Episode Transcription

The text below is machine transcribed.

Everybody it's Josh and Chuck Your Friends, and we are here to tell you about our upcoming book. That's coming out this fallow, the first ever stuff. You should know book Chuck, THAT'S RIGHT! What's the cool super cool title we came up with it's stuff. You should know Colin an incomplete compendium of mostly interesting things. That's right and it's coming along.

So great we're super excited you guys. The illustrations are amazing and there's the look at the book. It's all just it's exactly what we hoped it would be, and we cannot wait for you to get your hands on it. Yes, we can't, and you don't have to wait actually well. You do have to wait, but you don't have to wait to order.

You can go preorder the book right now everywhere you get books and you will eventually get a special gift for Preorderg which we're working on right now.

That's right so check it out soon coming this fall welcome to step. You should know a prodection of I heart radios, how stuff work hang and welcome to the PODCAST, I'm Josh Clark and there's Charles W Chuck Brian over there flying Solo batching. IT UP T ta, stag party up in this piece OAND. This is stuff. You should know you remember the happy days where they had a stag party, Richie and potsy and Ralph mouth went to a stag party with, I think, richy's older brother, who I believe his named Chuck.

I think his name was chuck, but I don't remember what happened. I I sort of remember that episode.

I think they just got a little freaked out a little titolated arouse and then freaked out, I think, did sounds like what would have happened. Did phonsie fix a jute box by hitting with this fist.

I think that even may have been preju box ponzie. I don't even know that he was wearing a leather coate at the time he may have just been wearing that weird gray jacket that he wore at first yeah like the mechanics jacket, and that would make sense because I think chuck was only in the early days of the happy days - The happiest days right, but then remember they like kill them off like pretty graphically he suffered from dysenterry for basically three straight episodes and like that's all they focused on and then he finally just died, and they said man this. This is called H happy days. I think we need to just get rid of them yeah. I think they change their show runner after that yeah.

So we're talking about ultrasound right now and if you had Tisenterry, I'm not entirely convinced that ultrasound would help.

But let's say you had a kidney stone. Instead, okay friend ultrasound would help with that kind of thing.

Yeah they could. They could sniff out a kidney stone yeah they can as a matter of fact wel. What's funny. is they do everything but sniff yeah thet? You sound in the use, vision, a'se the wrong thehey, don't snifver take yet.

Oh boy, that was great, should be good, so ultrasound, everybody knows what ultra sound is just about everybody. Seeing an ultrasound picture.

You see little babies like in the womb, developing and they're, getting all cute and everything, or else you see him really early on and they're, not at all cute, but either way.

I think everybody's pretty familiar with ultrasound and I was too, but I still learne quite a bit from this incredibly outdated article by Craig Frouden, Rich PhD yeah and you're speaking specifically of what's known as a Sonagram when a a device that you know we're going to talk about this in more detail, but a device called a transducer probe.

It's so great is either put on you or in you MM, depending on preparably on you epending on what they're after or how close they need to get sure, yeah absolutely and then what well I mean you know I can speak from experience. One of the best things in the world is when you see that first little picture of baby and heartbeating I'll bet, and then the worst moment is when you go in there and get one and that heart isn't beating yeah and it's unnerving moment when you go in there for that stuff and, like I said it can be it can. It feels both great and terrible thand I' experienced all yeah, but the thing is about ultrasound chuck is most people think that that's what it dos for us is check on babies, but it's ust for a whole bunch of other stuff yeah as well, which will talk about and they're starting to find even more cutting edge techniques for it to so.

It's actually pretty interesting stuff and the whole thing magically is centered on crystals that are actually hidden in the incredibly greatly named transducer prob mand. They actually, you know in a way squeeze these crystals and when you squeeze crystals, especially ones that have in arregular shape they do something amazing.

They produce energy vibrations. In this case, and so by squeezing the crystal a vibration, a sound goes out.

A very high frequency sounds ultra sound. What mightit is it is ultrasound on the order of something like this article says one to five mega hurts, but I saw twoo. Twenty is much more standard, Oh yeah, and it hurts his how many of the same part of of a wavelength of you know sound or something like that would pass by a space appointin space every second, so in this case, Sey, like the crest of these wavelinks, these ultra sound wavelinks, the something like twenty million of their crests would pass by one point in space in one second, very, very high frequency, very, very tight and which makes them very, very energetic.

So those are the the vibrations the sound that is produced by squeezing crystals, and you would think just squeezing crystals is pretty pretty great. Let's just give this thing a blue ribbon for being a wonderful piece of technology, but it gets even better than that yeah I mean, if you're talking about the fact that there's a machine that then calculate these distances from the probe to whatever it's trying to measure and then basically can create a two and now even three dimensional picture of that right. It seems like magic.

It does, especially because those those sound waves that propagate from the crystal being squeezed, which I like to think of, is the crystals being squeezed and it's making the sound and delight.

It's not like a painful painful sound that, like its just like yeah, that feels righat, so those sound waves when they travel into the body they hit all sorts of stuff, they hit tissue, they hit liquid. They hid everything and it's everything bone yeah and the the higher frequency of a wave, the more likely it is to bounce back.

So th a lot of that stuff bounces back and when it bounces back chuck. It comes right back into those crystals and when it hits those crystals, it actually produces electricity and then that electrical impulse is what's converted into through some sort of black magic that I have a lot of trouble. Wrapping my head around into images, so sound gets translated into images via electrical impulses and at the heart of it all are those crystals yeah. I think if you were to ask your average person, if a ultra sound like it just a yes or no question like an ultra sound, does it use actual crystals to produce an image?

You would probably get left out of the room by nine out of ten people and say, of course it doesn't that's some sort of weird wicken hocum right that you're trying to sell me on it's, not real, but it's remarkable. I had no idea that it uses crystals yeah. I think this machine is actually second only to the brethalyzer machine in surprising complexity.

Man An and I presume the ULTRASA machine was pretty complex, but Yah. I had no idea that they were squeezing crystals in there yeah in one thousand nine hundred and forty two. There was a neurologist who used ultrasonic waves, a as a tool as a diagnostic tool for the first time, name, Carl, with Akad Dosick, and he was trying to search for brain tomers through someone's skull yeah, and I think it was not until e Nineeen so about sixteen years later. Fifty eight that it was first to use for a SONAGRAM WITH DR in Donald Yeah and the great advantage of ultra sound is that you're, just your sending soundweights, which Youre Mechanical in nature into the body you're not using ionizing radiation like Xrays, so you're not going to like produce tumors, necessarily there's not you're, just not exposting being exposed to radiation energy, you're being exposed to mechanical energy. Again, just acoustic waves of sound.

But what's amazing about this, is that that that sound? Those echoes from that sound that bounce off of the different barriers or what they're called say like between blood and tissue, a tissue and bone as they bounce back up and they're. Converted into images you can see into the human body without using xrays and without cutting somebody open. So was an enormous advance that I think really gets overlooked, at least by the general public.

As far as medical advances go like, it was huge when we figured out how to do this yeah and that's why? If you ever go to get a Sonogram or something like this, and they show you an image of your little bread, loave baking in the oven and you catch yourself in your head. thinking, looks kind of cruddy to me.

Just put your foot in the door and slam it real, quick right and make sure you don't say that out loud in front of anyone in the room, because it is truly a little miracle machine just to get an image that looks that crutdy right, especially don't say it in front of Karl Dosik. No, no, it would really hurt his peopl, and all this I mean this stuff is remarkable, because it's the same concept of just the sonar that we use in the military in the sonor that bats use yeah and, as a matter of fact, like our understanding of Echo location, which is ultimately what it's based on. It's shooting out sound and then listening for the echoes and then taking the information right that those echoes bring back to judge things like distance shape, size all the UF. You can get a lot of information from sound if you know how to use echo location, that's what's happening, we're squeezing crystals to make the sound and then in turn after they shout they turn into ears. Listening for the echoes that come back and the echoes that come back ultimately become those white or bright or light areas on a sonogram that that form like the shape. Those are the echo yeah and it's way better, the very first sonagrams they would get boxes of bats.

They would open the LID and throw it over the pregnant belly very fast right right. Let them fly around for a couple of minutes and then take those bats into another room and give them pads of paper and pencils right and said to draw what you heard and bats are actually pretty good at drawing most of them. aret surprising, honestly, t t it looks about as good as the currents onogram yeah.

So I guess you're, not a big you're, not super impressed by t e the resolution.

You know it's wine, like I said when you, when you realize, what's going on it's truly a miracle and the Three d ons yeah I mean those are kind of creepily accurate right. They are. They have a little uncanny valley thing going on Bat, not sure why yeah, but they definitely do, but that's a huge advance in ultrasound because, like originally in Ultra Sone, especially if you just see the flat one that almost looks like a grainy xray or something like that, but you're, seeing something like soft tissue, that's another advantage of ultrasound over xray xray typically shows much harder stuff, whereas an ultra sounpart. So you even like blood, something is nondense, denseless sure. What's the opposite of Dence viscus loose Lucy, Gizy, yeah, Lucy Gas, even as something is, is anatomically. Lucy goosy is blood.

The ultra sound can capture that because of the high frequency and the other. The other great thing about using high frequency is that or the other reason we use high frequency is the the higher the frequency, the greater the resolution, and it's not a perfect analogy, but it's similar to how. If you increase the magnitude of a microscope, you can see smaller and smaller stuff.

It's very much similar to hiher the frequency of say, sound in an ultrasan machine.

The more finely detailed. The more resolution you can have y problem is is that the those higher energy wavelengths tend to to bounce back tend to reflect very easily lower energy travels further and further through the body. So what they figured out is you can combine these and that's how you ultimately get thred imaging, which Wi'll talk a little more about in a minute. You want to take a break yeah. Let's take a break and we'll come back and talk about all the parts of this.

I was about to call it the wonder machine, but we already have one of those o the Miracle Machine. mirical machines good all right right after this all right, so the miracle machine has - and you know the they don't explain any of this stuff. They basiol that you now you go in there and they're. Just like hey this thing works.

This is a bit of black magic and just sit back and and open up, and here comes the probe yeah. We, I think we should go over the list that appears in this article that was apparently written by Franz Kafka.

All right, we have to okay agreed.

I have ha feeling you're talking about the final few things about what happens during an ultrasond examination.

Oh, oh, that part yeah, sure. Okay, all right! So you got your tranducer Prob, which we already talked about a little bit, and that is the thing that tha the eyes ind the ears that sens and receives those waves and like we said it can go if you, if you see this in a movie, then you're likely seeing the kind that they put on your belly right because you're far along, and they want to see like that little baby in the body parts and everything that is later on in a pregnancy at first they use the one that goes.

You know into the vagina, witha kindom strapped on the end of it not Su that right, but rolld down.

Sure I mean that makes perfect sense.

You know, yeah I mean you got to put some sort of protective covering over it, okay and what better than a condom to fit over something that's sort of shape like a peanuts Gotcha, and then they loobe that thing up and then up it goes and then that's how you check on things in the earlier parts of the pregnancy.

I would hope that they would have these much smaller.

Is it well? I mean I, don't they don't use Hem AG, they need to use the Magnam okay, Al Right, but even still e condom fits very loosely to I should no okay, okay, that's what I was after Yeah Y.

It's I'm trying to I'm looking around the room that you're not even in to try and compare it to something. But what does that mean?

Well, I mean I'm ine we're working from Home O. No, you said you were looking around the room.

Yeah try to compare to something, but I'm not there correct, I'm looking for a like object in the room that you're not even sitting in yeah know. I got what youere saying I was making a different joke that you're not picking I'm not picking up on it. Let's say it's as big as this highlighter sort of like a sharpy magic marker, okay, okay, roughly yeah, all right, so I think we're together on the size of the transducer pro thats used early on. It's inserted man. They might use that same. They might use that same one. What whatere you going to say? How did we get through of like breastfeeding and female puberty, and this one is the one that's tripping us up, so I know I have no idea, I'm going to get us back on track. Thou'll watch this all right that same wand, wand, great word for it.

It might be used anally, orally, all sorts of different ways. They might stick it in whatever orifics they can. It's not just vaginally, depending on what they want to get a closer look at sure.

Is You know, especially if they're not just looking at a baby, okay, yeah yea, let's move on!

Let's do all right up next on the list is the CPU and that's you know, that's the little computer that does all that that black magic math yeah and it notes here in the article that contains the electrical power supply.

I noticed that too. I thought that was really specific, so yeah like if you look at any any ultrasyuld machine, the even the most cutting edge ones, that they have now look pretty much the same as one you would have seen in like the s yeah they're, just a little slimmer, they're, a little more user friendly they'll, probably have a touchscreen.

I saw that the I think it's the SEAMENS SACOA has a Jel warmer, I'm sure is very appreciated by patients e Nice, but I mean for the most part, it's just like everything that this article from I don't know. Probably two thousand and eight yeah it just is describing yeah. You've got your trandusor pulse controls and that's where you can change the frequency. The duration of the pulses. The amplitude right will look, will explain what that means in a little while to the to the tech they might understand. What's going on, but really it's them saying like get clear, focus, go deeper, threedmode that kind of thing yeah, but to the computer. It's like no we're messing with the amount of electricity that's coming and going through the crystals correct. Okay, all right! You get your display that speaks for itself, sure it's a little monitor.

It says on here: Keyboard, alright inputs, stata yeah. I thought that was pretty funny to the next. Two are my favorites of this list, though? Why don't you go ahead, then? Take it away hm I wasn't expecting that was taking a super coffee.

You've got the disc storage device which could be anything from a hard drive, floppy, disk or CD. Yes, and it says that it stores the acquired images and I actually wrote I wish you could see this. I wrote Haha under that part clearly does not have a USP drive, no clearly, not or any kind of SSD driver.

Anything like that, but then the last one chuck is the printer which I'm sure still exists, but I'm just guessing that they were in describing a dot matrix printer in this one, no the printers there, but it's, but it's when you know it's one of those little guys that you just put punch the button and it spits out and then they tear it off.

Yes, so I mean you know they can email, you a Jpeg, I'm sure, but they're also like here. This goes on your fridge.

Here's a butterfly made out of letters, Ogodi g home with this right.

Okay, so again, that's still basically the components of a ultrasan machine. What I was like, surely surely this article is just hopelessly out of date, and I mean it really is 'nd it doesn't it didn't capture? You know some of the cutting edge stuff that's being used today, but really ultra son machines haven't changed that much in the last like ten, twenty, maybe thirty or so years, they've, just gotten smaller, more powerful and, as is like computer technology, is improved so to has whatever computers you're going to find on board and ultrason machine, but the t e, the nuts and bolts of it are still generally the same thing and the the key, though the thing that's really changed over time and gotthen better and more sophisticated and varied. Is that transducer probe yeah, because iitaly yeah for sure, if you're going to make any improvements, you want to make it to the transducer pro, because it's going to have some pretty big effects in the keyboard?

Maybe maybe so because you do want to input data yes easily uhuh, but with that transducer pro initially, they had say like one crystal and that crystal would shoot, basically a static beam that was going out into your body and it would basically just take a snapshot of whatever it came in contact with.

There might not have been much adjustment to resolution to death, to focus anything like that.

It was just like here.

What do you expect? It's s give me a break you're looking into a human body using sound waves, just be impressed with that, but then, as they started, to figure out how to add more and more crystals into in a Ray, an a ray yeah, you can do all sorts of different things. And now, all of a sudden, your output of sound waves can be adjusted crystal by crystal, and your input can be adjusted crystal by crystal as well. So the resolution overall is just magnificently improved since they started making a rays of crystals in these transducer propes yeah and you did a nice little quicky overview of how it worked. But I don't think we mentioned that it's based on a principal called the piazo electric or pressure elix electricity effect yeah. We didn't and that's discovered by a couple of dudes in the in s Pierre and Jacque Cury, any relation. I mean to look that up yeah. I think Pierre is Marie Curi's husband, okay, one of the two are, I'm pretty sure it was Piere Eah and one of the few times that wife has overshedowed the husband's accomplishments yeas, but all three of them were extremely accomplished. Oh sure yeah. I don't want to know the carries yeah they'R, its kind of tough to they actually contributed quite a bit.

I mean how much do you want to go over this again? How much more detail do we do we want to throw on people?

I mean, I think we basically already explained it. We just left out that it's called the piazzo electric effect, which the cures discovered. I mean yeah, but again, ultimately, you squeeze a crystal and then it makes a yelp and then it listens out and the whatever bounces back gets converted into electricity. It's a it's a it's a inherent property of a regularly shape crystals. That is just a sounding that that actually happens in maybe even more astounding that humans figured out how to harness it to look inside the body.

Yeah and you know they're. The two most important parts are obviously that in the CPU and the CPU to be able to figure out - and this of course just program to do so - it's not an emotional living thing that that yeth had a fire under its but right, but the way that it figures out how to basically plot these I mean it's kind of plotting. Densities is what it's doing at the end of the day. Don't you think yeah for sure, based on the echoes that come back in the distance of them and yeah?

How energetic the echo is, because you know when, when a frequency of sound or wavelink hits something, and it's bounced back, it transfers some of its energy.

I don't think it's.

I don't want to say this because we're going to get an email from physics people, so let me just cavy out it with that is expudi. I would be very surprised if there's any situation or many situations, especially when you're talking about something is, is clugy as the human body, where you're going to get a hundred percent reflection back rut based on the different kinds of intensities that are received back into that crystal those can be measured and you can map like. Oh, this is actually a very solid part compared to this.

This part, which now you can see, is the edge because it just kind of tapers off and the the wavelink didn't bounce back quite as strongly because some of it misedor some of it, was absorbed yeah and the cool thing about all. This is its done in real time.

It's not like they're doing this and then a couple of days later you get your photo. I mean it's all right there right in the case of a Sonagram, and I guess every every use of it, but that's the only one I've experienced personally yeah.

It's right there on the Monitor, and you know you hear the little heart beating to so it actually record sound as well.

That's NEAT and this article didn't really touch on that.

But that's that's just astounding to me. It's like that's the most like sonar. I think is that I mean that's. That's where sub it's the same. ECHO location is all the basis of this right. Yeah whereyou're, making a soundnd Han listening back for an echo, but in this case wev figured out how to transfer those.

Those sounds that or what comes back into images, but it would make sense that you could also just maintain it as a sound to right yeah. I mean I would think so I mean that's what a hydrophone is that itwas underwater mikes that also just listen to you know sound tha, I'm a little stumped on that one I have to admit, or maybe there's a tiny microphone attached. Maybe so shube quiet the Microphonelis?

No, I think, that's probably just a part of the the programming, and maybe perhaps that is the easiest part.

Perhaps so, but I really feel like we should just come totally clean and say that totally guessing that was all educated guest, yes, which you can say, is also just making up step on the spot. Yeah someone someone can correct us and we'll read it Ou loud yeah, we'll bread it out lere. We do that kind of thing.

So, like we said, we've been talking about the TD variety theythey.

I guess this was around the to early twosands because they talk about sort of the new thred imaging and it's it's been around for a while. Now right, it's basically the standards thred, although I think td is still you know very much in use o you think Tud's the standard, I think so, okay or maybe it has to do with how far along as far as Sonograms, go right or really what they need to do, but the what they need to see. I think it probably also depends on that as well, but the so two ds that standard the one that almost looks like an Xraye. It's basically a snapshot, it's kind of grainy, but that's that's what people think of is a a standard td, Sonogram or ultrasound picture. Yes, then, then, you've got thred, which is that comes out as a result of the crystal Arras Right.

So you can you can change the frequency of the pulses that are going out, so you can sense things further away with the slightly lower frequency ones and sense. Th things closer with the the higher frequency ones and the t whole thing puts these images together to create a thred picture.

Yeah and, like I said, if you've never seen a thred picture, it ain't right from a SONAGRAM.

It's pretty interesting. It's remarkable that they can get this level of detail and part of it is surely to delight parents to be there's no doubt about it, but it's not just for that. It's not like hey! You want to see an even cooler, creepy picture of that developing circus peanut, because we can. We can do that now.

Yeah, it has a lot of uses. You can there's a lot more detail.

You can really assess development of of limbs in the face of the of the baby to be, and you can really get in there and kind of see more with your eyeballs. What's going on well, plus also, I mean, if you're looking for something like a tumor, it's much harder to see a tumor and two dimensions as like black and white shadows.

Then it is the sea like a three dimensional lump, so that's super helpful for thre D as well, and then there's there's another mode called m mode, remotion mode, which I believe is basically a bunch of twod images that are just taken in such rapid sucession that they are basically act like a flipbook or a video right. You can see this in in basically real time or just slightly delayed real time, because I know you kind of reference that this is all happening like immediately, but like the pulses that are being sent out and then returning are happening on the order of like millionts of a second yeah over and over and over again, there's there's that kind of old timy single beam. That's a constant wavelength!

That's not much in use. The new ones are just very quick pulses that are shot out many many times in a single second and as those things are shot out h, the stuff is returning just mind, bogglingly quickly to the crystals to be turned into data.

Now, that's not the the Doppler of one is it?

No. Okay. Doptler actually uses a steady beam from what I read yeah, so the Doppler ultra sound. It's mainly used to find out, I mean I'm sure they can use it for more than one thing, but it seems like the major uses to measure your bloodflow rate and go to your heart. They can go to your major arteries and they can basically see if you've got any kind of blood flow problems, because it's measuring a moving thing going through your body yeah, and it actually looks like a weather map where they use doplerade army. Most people see dopplaradar use for things like tornado or something like that to show different wind speeds so, like the different flow speeds of the blood flow, will be different colors and they can read that and be like. Oh, your blood's flowing nicely right. You got no problems right Dopbler, so I feel like we should take another break Huh. Oh my gosh. This is so thrilling that I think we need to to catch our breath. All right, we'll talk about some of the other things that you can do with a miracle machine right after this you know chuck. It really gives me a tremendous amount of comfort. Hope, good will m all sorts of stuff like that that we've come up in our twelfth year with another name for a machine.

Yeah like we had wonder machine basically from the beginning. I think so, and here we are in year twelve and we've just named another machine, the beaniful machine yeap.

So we talked enough. I think about well we're going to talk a little bit more about it about abstet, abstectric man. I knew I was going to do that.

Obstetrics Yep and when you go in there like I said part of it is to delight parents to be and say here it is everything's going heartbeat is strong, everything's happening, but they're also doing all sorts of things. They measure the size of thefetus.

They use a mouse to sort of click around and measure different distances.

They determine do date.

They want to make sure that fetus is in the right position.

They want to make sure the placent is in the right position.

They want to see how many fetuses there are in there. That's when you get the old by the way did not know if you knew this, but there are actually three living things inside. If you right now or eight so growth rate, you can detect the ectopic pregant pregnancies this way, yeah, that's a big one. It's a very big one.

That is when the baby is implanted in the phlopian tubes instead of in the uterus, and that means it is not a vible pregnancy right, so the life threatening for the mom.

What else amiotic fluid you got to make sure that there's enough cushion around that baby yeah for the pushing well yeah? Actually, that's eventually yeah and then, if you want to say, go in and take a sample of the amniotic fluid which you can do a lot of things by sampling, amniotic fluid to test.

So there's a lot of reasons to go in and draw some amniotic fluid.

I don't know why I'm trying to convince everybody that that there's reasons to take samples of amniotic flun Jus Etoe there is, but at the same time you can sit there and look into the into the womb.

The womb is okay right, I'm not like using some archaic and now offensive turm. Am I Jeez? I don't think so. Okay, I don't think so either. If I am please forgive me, I'm genuinely unaware of that. So scool me. If I'm, if I'm wrong, like, I don't think so. Anyway, it's called a baby box these days, my friend exactly yeah.

So if you want to keep an eye on the baby box, while you're getting a sample of the amniotic fluid to make sure you're not accidentally poking the baby, that's the ultra sound is really effective. For that to hand, can you believe they used to do that blindly?

I was reading an article about using ultra sound to guide spinal tap insertion, and this article said that it that the authors believe that, even though that you can use ultrasound for this now that the technology is widely available, most neurosurgeons prefer to just go in blind because it's more thrilling seriously.

This was an academic journal, Article that I was reading and they just said it so they crack open some Amel, Nihra, t sniffit and then go in there, yeah wow wearing a Hawaiian Shur.

What else can you do? You can use this for cardiology, we talked about the blood flow, but you can also literally say: Hey.

Is there something going on inside of your heart? Let's go look Yep, and especially with thred and real time stuff, like you like it's one thing to say: okay, well, the shape of your heart looks pretty good or the flow of your blood looks pretty good, but thanks to the MMO, so you can see it in motion. You can actually see make sure that the valves are opening and closing correctly in the right, the right time, like it's basically just peaking in real time onto the operations of your of your body using mmoe, it's pretty pretty amazing stuff. It's amazing. We also said, of course, you can see kidney stones which, by the way, I think we should do an episode on kidney stones eventually have you ever had one?

I don't want to say, because I don't want to jink myself. Okay, so you haven't, but you fear it.

Yes, that's it's a way to put it for yeah. I've never had a kidney stone either or golfstones. I've never had any stones inside me.

It's good. I've heard that getting those out is quite the ride.

Yes, you can also measure blood flow through the kidneys to you can detect prostate cancer. You can see lumps on the prostate, that's one of those instances where they'll be using the wand yeah.

So I also said earlier on Chuck that they're getting smaller and higher resolution and more portable and one of the places that ultrasole machines are showing to pop up more and more, and I think now, it's probably just a matter of course, based on how old this article is, but n emergency rooms they're, starting to really become kind of par for the course to like. If somebody shows up and says, like you know, they're doubled over an abdominal pain rather than sending them to surgery or even up to radiology yeah. They will, they will just apply and ultra sound there and be like Oh yeah. You've got a a ruptured stomach yea, so we need to. We need to get. We need to get that fix pretty and they say now. I wish I would have brushed you into surgery right.

I need a second opinion.

Yeah ultra sounds are safe there.

You know there have been questions because anytime you're applying heat and energy near organs like very close to Orgon, sometimes yeah. You got to really kind of consider this and there have been some reports here and there of low birthwaight babies.

If you have had frequent ultra sounds during your pregnancy, but they have basically come out and say: Ultra sounds are safe but sort of like an xray. You don't want to come in here every other day and get one ht. You want to only do it when it's necessary because there is heat and apparently the formation of bubbles because of this heat. When dissolve gases come out of that solution, you know that's a thing, but that they are safe yeah. I mean we've been using him for sixty seventy years now and there's been plenty of chance for if that's an issue for to become obvious and evident with I mean it's, it just seems like it's very safe. I did see that theyre. This article says that there's not been any documented studies that show harmon animals and that's HAP At's, not true. Actually, there are animal studies that have shown that exposure to some kinds of ultrasound, typically continuous wave, which is just a concentrated beam of energy yeah that that can actually cause thermal heating, which is not good and then theres. I found another study from two thousand and seventeen that said some kinds, especially continuous wave, but also super super quickly. pulsed ultra sound has shown that it can break up DNA strands. Oh interesting, which is weird because, like that's one of the things that people have always pointed to is well, this is just mechanical energy. It's not going to damage your DNA like ionizing radiation is yeah, pretty it's a pretty startling revelation and they actually said in the article Yand again it was a academic journal Article. I can't remember which one, but it said like this is going to be of like a lot of interest to a bunch of different fields, because we didn't know this before Ye. That is interesting.

It is, is it time to read the Franzkaka yguide to getting a ultrasound? Yes, I also want to say chock before we do, though, the there again there's basically no evidence that there is harm that comes from ultrasound exams in obstite and obstetrics, especially when it's done by a train person.

Oh sure yeah.

It doesn't sound like it's anything to be worried about overall yeah.

I don't want to scare anybody. Unnecessariy Yo, shouldn't hur people should not be right and you shouldn't both yeah all right, so Franz kafkas guide to getting an ultra sound number one man if we could get vernerd herdzocg to read this list. That would just be amazing. We've got a pretty good runner up in the room. Nole DAS, a great job I shuld, we should get noll in here. Okay, we can doublhem man number one is to remove your clothes.

Okay number two is the ultra sonographer drapes the cloth over any exposed areas that are not needed for the exam aright. Okay check number three: We should really get Paul op Tompkins. If we want to do this right, actually, why? What would he do? Well? He does a great Berna, Hurd Dog, Okay Yeah. We should just get vernor hurtzog yeah man he's down for whatever it seems like what stuff should. I know.

Yeah the ultra sonographer applies a mineral oil based jelly to your skin, all right, it doesn't say this or to the condom on the probe. Okay, the Jelly eliminates air between the PROB and your skin to help pass the sound waves into your body yeah and if you're lucky they're using a seman Siqoa brand ultra sal machine, which has an on board Jel heater.

That's right!

Are they giving you money, Noa? Okay? What someone that seamens money?

Hey Man, they got they're loaded, they're, one of those companies that kind of make everything right, yeah yeah.

What if they did hear this and reached out to us and we're like hey.

We really appreciate it. We're sending you guys each an ultra sem machine, hey man I got it can go with my I've got a seaman's brand car charger, electric car charger. There you go I'll bet, that's something that was left off this list. You can charge a car with it. It's right, decent ultra solme or the verrys least jump one off. It's Geay, it's got jumper.

The ultra sonographer covers the probe with a plastic cover, that's the condom.

He she and I'm going to add h. They pass the probe over your skin to obtain the required images depending on the type of exam the probe may be inserted into you.

You want to finish up here with the last few. Oh no you're doing great all right number. Six. You may be asked to change position, change positions to get a better looks at the area of interest. Okay, there's two thousand and eight popping up again number seven. After the images have been acquired and measurements taken, the data is stored on a disk.

You may get a hard copy of the images they may write and sharpy what it is on the desk even and then the now here, the tois yeah. This is where it starts to take a kind of a dark turn number eight you're, given a talet to clean up and number nine.

I can't believe this is actually on the list.

You get dressed tjust like the grimest list of procedures, you've ever heard of, and they stop at nine number. Ten should have been, then you go, give them your credit card and pay your copay right number. Eleven! You walk out to the park tat the parking lot number twelve wualk back in, because you forgot to give validat number thirteen check your back seat and make sure there are no creeps there. Alright number fourteen remove the creep that you found wow, quite a lest so we're talking about the future of ultra sound in this this this article isn't really captureit. So I started look around. I found weirdly enough a list of cutting edge ultra sounand stuff on the in the Daily Mail of all places, and the list is actually terrible because Itas Daily Mail article, but one thing that they did talk about, was tractor beams that they figured out that you can actually lift something as small as a bead. At this point using sound waves like in star wars, you would think kind of like SAR wars, but no not at all. It's actually levitating more than a tractor beam, treck tobe makes it sound like you're pulling something upward toward you. This is actually raising it up away from you, but there are all sorts of applications for this, especially in water, because you can use these sounds in the different arrays and the different configurations of a race to move something left or right. It's called steering the beam and they actually use it for for ultrasounnd imaging to, but you can actually move things like, say, an oil slick. You could kind of basically drive it into shore away from shore to some other place where you want to capture it. That's a eactally, pretty cool applications for it in medicine.

They' figured out that if you give somebody a drug say like a chemotherapy drug, some of those Khemotherapy drugs only partially cross the blood brain barrier so they're only partially effective. The rest of his gets metabolized and N. You pee it out or whatever.

So they figured out that if you give somebody a chemoftherapy drug and then blast their brain with an ultrasound machine, it will push the drugs pass. The blood brain barrier into your brain and they'll be that much more effective.

Oh Wow, I thought that was pretty cool too.

There was a man who was awakened from a coma because the doctor, for some reason, blastis Hypothalamis, with a continuous wave beam of ultrasound, but even the doctor was like this may have been coincidence. But you know I don't know man, it seems like thereare all sorts of applications that are just starting to tap into yeah. I've got a couple more. Let's hear: Hem ultrasound, assisted, Lipa Suction, basically, burning up fat cells driving it out of there.

Yes, but that really kind of points out that yeah this actually can create heat, because that's what they're doing is melting fat calles using sound, which is the thing, but then they've also figured out that, depending on the frequency of the sound of the sound wave, it can actually stimulate growth and function in cells. So theyv found that like persistent wounds like ulcers and things like that, you can actually stimulate them to heal by hitting them with soundwaves yeah.

I love it.

Is there anything an ultrasol machine can't do chuck? I don't know, I do know and I'll tell you what the answer that is and it's no, you gt anything else. I got nothing else, but a listener: Mail, okay! Well, that's it for ultra sounds forty seven minutes, that's impressive! It is since I said it's impressive it's time for listening to me, Hi guys. I am an eleven year old boy from the West Coast.

My parents introduced me to your podcast a few years ago and I became interested in podcast and podcasting because of you.

Nicei've recently started my own podcast called a child's perspective of current events night.

This sounds wonderful yeah. It does Goin to check it out. I haven't had a chance to listen yet DAKON, but he said I would love it. If you hould mentione my podcast during your listheer mail section, it would really help boost my audience monthly listeners.

Thank you for your time. I really hope you will consider mentioning me on your podcast and that is from Dagen Hofeld Nice Na and again it's called a child's perspective of current events.

I love that straightforward name. It's like Stuff You Should Know it says a all. It definitely is in the same wheelhouse for sure yeah, but it's not derivative in any way. No, no, not like it.

It's just in it's perfect simplicity, yeah. I love it and I'm going to give that a Lisson this afternoon Dagan and see how you're doing and if you need any other advice, just let us know, but so far the you've done. The smartest thing, which was to get someone on a superpopular podcast, to talk about your podcast right, exectly top one helps hopefully you'll get an sysk bump out of this, and I'm going to go, listen to dig, and so thanks for letting us now right, yeah right.

If you want to go check out, Dagen's podcast go do that. It's called a child's perspective on current events. ' So great and in the meantime, if you want to get in touch with this, you can send us an email like Dagan did, wrap it up, spank it on the bottom and send it off to stuff podcast that I heart radiocom Stuff You Should Know, is production of iheart radios, housestaff works for ore, podcast for my heart radio, because it the IHAT radio, AP Apple, podcast on whereever Tyoo, listen to your favorite chows
