Ben Schofield Not on every video. Just on every video YOU watch... I'll be there, like a thorn in your side or like a ghost, haunting your every move. muhaaaha ;)
I had an ultrasound done on my neck because I had a strange bump about the size of a walnut just to the left of my throat that needed to be identified. I named it "Nick."
I’m here because I’m studying wave physics (pre-quantum) and my textbook lists Ultrasound as an example. It says that maximum energy is transferred when impedances match (minimizing reflection). This video uses very precise vocabulary and I really appreciate that!
The Echo part of that probably comes from the pulse-echo method that the machine uses. you can do pitch-catch, and through transmission as well but those are mostly in the manufacturing industry and not medical.
Honestly, why do you think that's something everyone should know? This person might have never been near one before and isn't a doctor. I honestly didn't know what the gel did, I thought it was lubricant too and I've had an ultrasound done on me. Don't be so condescending.
It actually is mostly just a lubricant that has other desirable acoustic qualities in addition to its use as a lubricant. Its ingredients are very similar to some commonly used non-oil based lubricants.
There's also an ultrasound gel recipe here in youtube. The doctors in medical missions going to poorer areas of the world make their own instead of bringing in a lot of gel to reduce baggage.
Hmm, propylene glycol and glycerin are also the majority of vaping juice (others being flavoring and nicotine if added.) They're also found in inhalers for asthma.
Ken Anderson about a year ago I found a pea sized lump on my right testicle. I went to the ER and got both of my balls scanned. So I can attest to the great feeling of this gel.
Ken Anderson I got lucky. Once I got scanned I went to a specialist, he told me it wasn't cancer and it was just a lump. And to come back if it got bigger . To this day it hasn't gotten bigger. Thank god.
Sci show can you guys make a video about animal symbiosis? Maybe like the clown fish and sea a anemone? I heard there are many other kinds and I hope you guys can make a video to share these animals
Hey, got a fun question... Why does baking at "altitude" differ from baking at "sea level"? And would baking be different on the moon or Mars with the same equipment?
My doctor sent me to an ultrasound technician after he found that my neck was too fat to properly see if I had a problem with my thyroid. Needless to say that I spent sometime after that appointment trying not to pick the hardened gel out of my hair
Everyone talks about how cold the gel is, and it's always in shows and movies as cold. Mine was definitely really warm... like above body temp. Makes me wonder if the place I went is the only place that bothers to warm up the gel. Haha.
I believe it was in national geographic that they were saying that ultra sound caused mutations, and that the only people that have avoided these mutations are indigenous tribes. I don't think sound waves would be powerful enough to do that however.
I have to get a yearly thyroid ultrasound, and can hear it every time, especially when the tech has it pointed at a major blood vessel. It's an odd sound/feeling, like interior cricket noises, and the rhythm changes based on how deep they're looking and when they're taking specific still images.
It can't be "sounds that you can't even hear". They are sound waves that you can't even hear. By the definition of the word sound, sound waves are sound only when they are heard.
Imagine that instead of our eyes letting in light, they shot out ultra sounds at say 100khz and our brains/ears/recievers used that to create our 'reality'. Kind of like sonar but for vision! I never really thought about how ultrasound worked to be honest haha
Oh, so ultrasound gel works similarly to immersion oil used with high objective magnification microscopy. Just with sound waves instead of light with use of index refraction. How relevant, I'm getting an ultrasound Friday.
Tracy Chen you know how oil doesn't mix with water? Well nail polish doesn't mix with water either, but nail polish remover mixes with nail polish, so that the nail polish gets sort of liquified, just like the dirt on dirty dishes when they are washed with water.
What are waves, like radio waves, electromagnetic wave, infrared waves etc.? I have seen many videos online but nothing satisfied me much. kindly put some light on above mentioned topic in your upcoming videos. also mention things like electricity, Schumann resonances, aurora and anything you like. Love to you tubers like you.
I wonder, if certain people could actually hear ultrasound noises through some sort of genetic mutation would it cause any sort of pain due to the frequency, for example the dog whistles that sound silent to us but a dog can hear, is it to them just a regular sound or is the reason they respond to it because of some other form of stimulus
Objection, Your Honor, there was no such thing as an ultrasound machine in 1950 when I was born (and according to Hollywood, everything was in black-and-white, hahaha!). Besides, even if it did, it wouldn’t be making photos (as in _photographs_ or _light_ drawings) but _phonos_ (_phonographs_, or _sound_ drawings) and yes, every single time a doctor prescribed any ultrasound imagery, the machine was emitting sounds even this old guy could hear (though I’m sure it also emitted ones I could not hear).
I was born in 84 and they didn't do ultrasounds on pregnant women back then unless there was suspected trouble. They didn't even all agree that ultrasounds were completely safe and do them every pregnancy until the late 90s. I know some people born up to 95 or 96 or so that never had ultrasounds either, at the time the resolution sucked so bad you could almost never determine even gender from them. I think it was mostly used in the larger more expensive hospitals that just wanted extra tack on fees in the 90s.
"That's why they are good for echolocation if you are a bat or dolphin." Well, it has never happened to me before. Although my friend told me he had thought he was a carrot when he had been high on mushroom and wanted to plant himself in the ground.
Feedback: One of the first images you used was of a knee ultrasound post TKR surgery. This would most likely be therapeutic ultrasound - you're not going to image anything shooting a beam of sound straight into a metal patella. You then went at length to talk about diagnostic ultrasound. It may have been worth mentioning therapeutic ultrasound, and how it differs from diagnostic ultrasound.
maybe Its just me, but how come when you yawn sounds get louder ? For example I work at a pool and when I'm at the top off the slide and I yawn the sound of the water running and everything else gets louder
A quick search turns up ranges of 1-20Mhz and 2-15Mhz. Even at 1Mhz, the answer is no. While dogs can hear frequencies we identify as ultrasound, they definitely can't hear the sound used by ultrasound machines.
So.. i just realized i am vaping ultrasound gel every day. - Yea, you guessed it, the main ingridients in electric cigaret juice is .. Glycerine, Propylene Glycol and destilled water/alchohol..
I've had three ultrasounds done in my life. One to check how my appendix was doing...And two to check out the source of testicular pain. They don't even heat it up.
Just throwing this out there. If you are pregnant and you buy a Doppler for your home, my sister has one that is about six inches, you don't have to buy ultrasound gel. It can be pretty expensive. You can buy aloe Vera gel. My sister talked to her doctor and it works the same. You can buy a big bottle of aloe for a few dollars and it will last you way longer than you are pregnant.
can it be counted as a photo if it's using sound waves? I have the same issue with gamma camera images and xrays being called photos but at least they're essentially the same thing as a photo (electromagnetic radiation affecting a medium).
I have a question- why do we cringe and shiver and feel the need to move around when we see gross stuff? Like if somebody had a dislocated joint or injuries to eyes and other sensitive places etc? why does it make us like, shiver?
I never realised that the gel even do something... I always thought is there because of friction...so that the ultrasound thing doesn't hurt when it's moved around on the skin....I feel really stupid and much smarter now at the same time
mR. StRAnGe as far as I know the water in a cloud freezes. Ice is heavier than water so it falls down. On the way to the surface the ice melts and becomes liquid again. But sometimes it does not melt and we get snow or hail instead of rain.
Why is yawning so contagious....???? do we have weak minds, does this simply show how easily we can be manipulated??? Sometimes i pretend to yawn to see who ends up yawning..... Its quite fascinating..
lol i thought it was just to make it easier for the tool to move around
Dumbfuck 🤣🤣
😜
My friend was an ultrasound technician but had to find a new job when he went a little insane. Apparently you have to be of sound mind.
Master Therion are u gonna comment on every video?
Ben Schofield Not on every video. Just on every video YOU watch... I'll be there, like a thorn in your side or like a ghost, haunting your every move. muhaaaha
;)
Master Therion hahaha
The door is on the left.
Master Therion I hope your fantastic puns become a regular thing in the Sci Show comments, kinda like Solid Banana's anus comments, heh
I had an ultrasound done on my neck because I had a strange bump about the size of a walnut just to the left of my throat that needed to be identified. I named it "Nick."
I’m here because I’m studying wave physics (pre-quantum) and my textbook lists Ultrasound as an example. It says that maximum energy is transferred when impedances match (minimizing reflection). This video uses very precise vocabulary and I really appreciate that!
Over here in The Netherlands we call those ultrasound machines "Echo". For example if I were to need an ultrasound I would say: I'm gonna get an echo
Aron Bekhuis We use the term "echo" for echocardiograms in English, since we can't abbreviate it ECG because that's electrocardiogram.
The Echo part of that probably comes from the pulse-echo method that the machine uses. you can do pitch-catch, and through transmission as well but those are mostly in the manufacturing industry and not medical.
Who the fuck cares man how you call it in your shitty country
Ganara426 What's your problem, brah.
Ganara426...Go back in your hole, you moron!
Do bat wings regenerate when they are damaged?
If they try hard enough
Krešimir Jurilj No. Only batman can do that.
Krešimir Jurilj darude - sandstorm
Lmao, thought you were talking about when your nutsack gets stuck to your thigh at first
Yes, bat wings can be very rapidly "repaired".
I thought it was just a lubricant
Honestly, why do you think that's something everyone should know? This person might have never been near one before and isn't a doctor. I honestly didn't know what the gel did, I thought it was lubricant too and I've had an ultrasound done on me. Don't be so condescending.
It actually is mostly just a lubricant that has other desirable acoustic qualities in addition to its use as a lubricant. Its ingredients are very similar to some commonly used non-oil based lubricants.
It can be... Most of the ultrasonic technicians in the industrial world use KY gel. It's cheap, easy to get, and it works.
There's also an ultrasound gel recipe here in youtube. The doctors in medical missions going to poorer areas of the world make their own instead of bringing in a lot of gel to reduce baggage.
it is :P
I hope that you have a Very Merry Christmas and a Very Happy New Year.
Have Fun,
Joe
You can treat deep muscles with ultrasound. You need a medium and water is one, gel is water. You need gel for the vibrations to work
Why does aluminum spark or catch fire in a microwave?
I think it was the one on metal in microwaves. But I could be mistaken. :)
But why does metal do that?
Love how he made it sound so matter-of-factly, even to bats and dolphins
Can you do one on cerebral aneurysms? I had one rupture at 19 and would love to learn more!
phantasm1234 ask him on patreon
You forgot to mention that farts can defeat ultrasound ! Medical science 0 : Me after some Mexican food 1 :D
Hmm, propylene glycol and glycerin are also the majority of vaping juice (others being flavoring and nicotine if added.) They're also found in inhalers for asthma.
and in a lot of food
and in tons of personal hygiene/care products like soap, makeup, conditioner, etc
Ah thank you very much for this, really well explained !
Had to double check that thumbnail
my chem teacher patented this gel, he's really cool (and old)
Which gel, because there are many. baby oil works about as well. a lot of the gels are water based.
i had this stuff put on my balls once when I was in the ER lmao felt dank-o-roni
Ken Anderson about a year ago I found a pea sized lump on my right testicle. I went to the ER and got both of my balls scanned. So I can attest to the great feeling of this gel.
i suspect you are not lying
no im not lying, my left testicle became swollen probably quadruple the normal size and I was in a shit ton of pain.
Ken Anderson I got lucky. Once I got scanned I went to a specialist, he told me it wasn't cancer and it was just a lump. And to come back if it got bigger . To this day it hasn't gotten bigger. Thank god.
Ken Anderson was your gel warmed. The gel they put on me had to have been in a warmer.
A side mark: In space you can use Water for Ultrasound (for eyes at least). Chris Hadfield shows that in a video about Eyesight in space.
Sci show can you guys make a video about animal symbiosis? Maybe like the clown fish and sea a anemone? I heard there are many other kinds and I hope you guys can make a video to share these animals
Why is there a solid banana around my ultrasound gel?
What?
Chom chom.
Hey, got a fun question... Why does baking at "altitude" differ from baking at "sea level"? And would baking be different on the moon or Mars with the same equipment?
this is so cool i never thought about it
(Neither glycerin nor propylene glycol are polymers, though they can be used as building blocks for polymers)
whoever invented ultrasound was a freaking genius
İ found this channel to be the best on UA-cam. I love how I can learn from here so fastly and useful things 👍🏻👍🏻
My doctor sent me to an ultrasound technician after he found that my neck was too fat to properly see if I had a problem with my thyroid. Needless to say that I spent sometime after that appointment trying not to pick the hardened gel out of my hair
Everyone talks about how cold the gel is, and it's always in shows and movies as cold. Mine was definitely really warm... like above body temp. Makes me wonder if the place I went is the only place that bothers to warm up the gel. Haha.
I was cackling at my ultrasound because the baby kept flipping us off whenever her hands were in the shot.
For the longest time I assumed it mimic the visceral portion, surprised it's mimicking the skin impedance.
I believe it was in national geographic that they were saying that ultra sound caused mutations, and that the only people that have avoided these mutations are indigenous tribes. I don't think sound waves would be powerful enough to do that however.
I just googled this few weeks ago.. crazy!
I have to get a yearly thyroid ultrasound, and can hear it every time, especially when the tech has it pointed at a major blood vessel. It's an odd sound/feeling, like interior cricket noises, and the rhythm changes based on how deep they're looking and when they're taking specific still images.
I love your videos guys! you make me so much smarter every day
That's a different channel.
very interesting!
that extends my knowledge about acoustic impedance..!
Thank you so much 💛💛🤍
It also makes a tasty treat
0:27 - actually, it's usually warmed. Still weird, but not all that unpleasant.
Now that I think about it, I'm surprised there hasn't been a misinformed scare campaign about the effect of ultrasounds on babies.
It can't be "sounds that you can't even hear". They are sound waves that you can't even hear. By the definition of the word sound, sound waves are sound only when they are heard.
you should have mentioned that 2D ultrasonography can be used to investigate muscle architecture using some handy equations!
ultra sounds.. neat stuff
Where was this when I needed it?
Imagine that instead of our eyes letting in light, they shot out ultra sounds at say 100khz and our brains/ears/recievers used that to create our 'reality'. Kind of like sonar but for vision! I never really thought about how ultrasound worked to be honest haha
Nice video! I liked especially the ending!
Henry Lehtovirta then why are you subscribed to this channel?
I was trying to be *very* funny like 30 seconds after the video was uploaded
*keep these questions coming
"Squishy bits"
Technical term.
Why is the image shaped the way it is? Like with the small part at the top and the big part at the bottom?
The waves spread out at roughly a 45 degree angle from the transducer, it's like a flashlight beam in pitch black, it can only see where the beam is.
is there less sound when it's cold?
Oh, so ultrasound gel works similarly to immersion oil used with high objective magnification microscopy. Just with sound waves instead of light with use of index refraction.
How relevant, I'm getting an ultrasound Friday.
I always thought it was just for lubrication for the machine...
thanks a lot bro
They should do an episode that explains why certain mint flavoured/scented things feel cold
My guess would be that it evaporates quicker than usual materials idk
Ganara426 sounds like a good guess.
Love your videos!! Keep up the good work :D
I thought it was just lube.
Ultrasound can also be used in physical therapy for tense, achy muscles
How does nail polish remover work?
Tracy Chen you know how oil doesn't mix with water? Well nail polish doesn't mix with water either, but nail polish remover mixes with nail polish, so that the nail polish gets sort of liquified, just like the dirt on dirty dishes when they are washed with water.
It's more like table salt dissolving in water but not in oil.
The nail polish dissolves in the remover (it's acetone) but not in water.
basically the answer to every how does this dissolve that question. Like dissolves like.
is the same gel used in ecg also.
What are waves, like radio waves, electromagnetic wave, infrared waves etc.?
I have seen many videos online but nothing satisfied me much. kindly put some light on above mentioned topic in your upcoming videos.
also mention things like electricity, Schumann resonances, aurora and anything you like.
Love to you tubers like you.

The funny thing is that how ultrasound gel works is so simple that the majority of the video is dedicated to how ultrasounds themselves work.
I was born before ultrasound (1956).
I was born in 84 and they didn't do ultrasounds on pregnant women back then unless there was suspected trouble. They didn't even all agree that ultrasounds were completely safe and do them every pregnancy until the late 90s.

can any complex lifeforms on earth detect by sensor or tympanum those frequencies ?
"That's why they are good for echolocation if you are a bat or dolphin."
Well, it has never happened to me before. Although my friend told me he had thought he was a carrot when he had been high on mushroom and wanted to plant himself in the ground.

Can u guys do a video about what might happen if the supermassive black hole in the center of our galaxy disappeared?
maybe Its just me, but how come when you yawn sounds get louder ? For example I work at a pool and when I'm at the top off the slide and I yawn the sound of the water running and everything else gets louder
Since ultrasound uses sound, it wouldn't be a photograph would it?
Can dogs hear the ultrasound?
Dogs can hear up to 79khz which means that they can hear some of the ultrasounds.
In aviation we use mostly the Mhz range I believe medical is the same. Because as frequency increases so does resolution and sensitivity, generally.
A quick search turns up ranges of 1-20Mhz and 2-15Mhz. Even at 1Mhz, the answer is no. While dogs can hear frequencies we identify as ultrasound, they definitely can't hear the sound used by ultrasound machines.
So.. i just realized i am vaping ultrasound gel every day.
- Yea, you guessed it, the main ingridients in electric cigaret juice is .. Glycerine, Propylene Glycol and destilled water/alchohol..
Hey SciShow
Oh... and here I thought that the gel was just a lubricant to help the ultrasound thing move around the belly.
Can you make a video about why water is denser than ice
Will you guys be making a video on antimatter or the recent news about antihydrogen?
everytime ive had one, ive heard the sounds. it sounds like bats clicking
So can we vape the gel? E-juice is made of vegetable glycerin and propilene glycol
How come some doctors cure tissue damage or infections with ultrasound? How does that work?
Impedance matching
Why do we itch?
Dead skin cells still remain on the body, therefore the body detects it, and wants them gone. (I think :/)
I've had three ultrasounds done in my life. One to check how my appendix was doing...And two to check out the source of testicular pain. They don't even heat it up.
Why are you stalking me? I was talking about acids and you make an acid video and when I have an ultra sound scan, you make this video.
So for an ultrasound thickness meter, the gel's impedance is similar to steel, or metals ?
or is this the same gel ?
when i get ultra sounds for my cancer or what ever i can here the sound
hey can you tell me to what is function of gelly in ecg
Just throwing this out there. If you are pregnant and you buy a Doppler for your home, my sister has one that is about six inches, you don't have to buy ultrasound gel. It can be pretty expensive.

as an Ultrasound student who just passed my SPI (basically ultrasound physics test) this is accurate.
As a 10" 3D portable digital ultrasound machine, this is accurate too.
can you make video about why we like music
@1:07 I'm a bat-dolphin
Its called couplant. Good explanation, but why not insert the technical term in the explanation?
Let's be honest... Hank probably asked this question.
How do rain drops form and release in a cloud?
mR. StRAnGe as far as I know the water in a cloud freezes. Ice is heavier than water so it falls down. On the way to the surface the ice melts and becomes liquid again. But sometimes it does not melt and we get snow or hail instead of rain.
Why is yawning so contagious....???? do we have weak minds, does this simply show how easily we can be manipulated???
Sometimes i pretend to yawn to see who ends up yawning..... Its quite fascinating..
I thought it is to prevent the skin from becoming another ultrasound source.
how about a video on whether spirits exist or not?
Meena Alekhya its called SCISHOW
1:33 so in short ultrasound gel = tasteless ejuice
As a sonography student we take the images not the doctors
