There's a new way to see inside your body that could replace MRIs, and it only uses water and sound.
So, your typical MRI machine uses magnets and radio waves to move protons in your body, creating signals that the machine converts into images, which is amazing. But, to use this machine, you have to step into a water bath, and then you're slowly lowered down at about 5 cm per second.
And around you is a ring with these tiny little sensors, each one about the size of a grain of sand, that act as a speaker and a microphone, creating tiny vibrations that build up into one fast sound wave that travels across the tank in 1/2000 of a second. And as the wave passes through your body, it changes shape depending on what it's going through.
The sensors in the ring go one by one until they've encompassed your whole body, capturing a whopping 17 GB of data per second. So, by looking at how each wave changes shape, they can create an image of what a slice of your insides looks like.
And it does this again and again and again as you're slowly lowered through the ring, imaging several hundred slices of your body in only 60 seconds, nearly 100 times faster than an MRI, which could mean more people could more easily get them. They're still testing this, but see when you can use it. Subscribe.
