So you can start imaging all these points. Transducer that sends out pulses along this wholeįace of the transducer you can image this whole region. It keeps doing this and it knows that you'll have points right here, difference between interfaces right here, an interface between I'm drawing these sound waves crooked just so you can see them. It'll reflect against this interface between blood and tissue. So there's something here,Īnd here's the end of it. Right, took that long, now there must have been Here's another interfaceīetween tissue and blood, so it's going to reflect again. Right, if it took that long to get back, it must have

It also knows the speed of sound, so it can calculate, all It knows when it sent out the pulse and it knows when that Here, between blood and tissue, it will reflect, comes back. This is going to keep traveling here, it keeps traveling. Let's just say there's tissueįrom blood or other things, or, sorry, tissue from organs, and then the red will represent the blood. Interface between the two media, which, in this case, we'll make it simple. It'll reflect any time there'sĪ difference in the medium, so any time there's an Toward anything in here, and it turns out it'll reflect. This transducer takes electrical energy, you plug it into the wall, turns it into sound energy. You can do x-ray, but too much exposure to radiation is bad, too, so a very good option You want to try to avoidĪn operation if possible. What's going on inside, you can operate, but that obviously sucks. Organ or some tissue here, or some tissue over here, you're worried something's going wrong, you got to figure out Portion of the human body and there's maybe a vital If you wanted to do some medical imaging or figure out what's going If it's a frequency above this, this is the range we can hear, if the frequency lies above this range, we give it a special name. Ear can hear frequencies from around 20 hertz to about.
