Body-ultrasound Sonography With Arduino

My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let’s take a look how far I can go with my simple items…

I was inspired by this a bit more complicated and more expensive project:

Here are the parts you’ll need for my project:

the main parts:

a gauge to measure the thickness of paint for 40 USD: ebay paint thickness gauge GM100
an arduino Due for 12 USD: ebay arduino due
a 320x480 pixel display for 11 USD: 320x480 arduino display
two 9V/1A power supplies for the symmetric +9/GND/-9V supply
ultrasound-gel for sonography: 10 USD ultrasound gel
for the transmitter:

a step-up-converter for the needed 100V for 5 USD: 100V boost converter
a common step-up-converter supplying 12-15V for the 100V-boost-converter for 2 USD: XL6009 boost-converter
