I really wanted to make a career in tomography. But had only one elective from another department and didn't know how to make it into this stream.
Everyone I know in the field has come into it laterally either from a prior software or hardware job in an unrelated field.

Pictures are surely what everyone wants to see, thanks. Animation that looks similar below. I’m not sure its that similar to MRI, but there are clear advantages to using US and it’s a new technique which hopefully get better. https://medicalxpress.com/news/2026-04-body-ultrasound-captu...
Presumably that's just a matter of better system modelling to fix?
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.
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.

Also my personal project which was inspired by un0rick but a bit simpler: https://williammeng.com/rtl-ultrasound.html

It’s difficult. Medical devices are not easy for a small business to break into and the big manufacturers don’t typically hire entry-level. Everyone I know in the field has come into it laterally either from a prior software or hardware job in an unrelated field.
The results really look rather blurry compared to the MRI... Presumably that's just a matter of better system modelling to fix?

MRI is done using X rays which have very very small wavelength compared to sound. And resolution of images i.e. less blurry varies inversely proportional to the wavelength. Yes some algo can make slightly better but I am certain that nothing can beat x rays in clarity for humans
