This is cool! I've got a personal project in the works to build an ultrasound machine just to learn how it works. There's a lot of electronics design, PCB design, FPGA work etc that in learning.
The probes themselves are used medical grade ones from ebay.
The hard part is that there can be over hundreds of piezo elements each needing to receive on their own channel. That means lots of expensive ADCs. Not to mention either having many pulser circuits or muxing a pulser to many elements.
- permenganate 4mo agoHave a look at this open source ultrasound project for some inspiration! https://un0rick.cc/ https://un0rick.cc/ Also my personal project which was inspired by un0rick but a bit simpler: https://williammeng.com/rtl-ultrasound.html https://williammeng.com/rtl-ultrasound.html
- polishdude20 4mo agoNeat! I didn't know you could use an SDR for that!
- kelu124 4mo agoHa Will, fancy seeing you there !
- drivebyhooting 4mo agoDo you have a GitHub? How do you source your parts?
- polishdude20 4mo agoNot yet. Once I've got it working haha. For the probe, you can find loads of them on ebay. For the electronics. Digikey, JLCPCB etc.
