There are quite a few papers in the literature about using high-end GPUs to speed up ultrasound imaging and denoising, for commercial vendors I'm guessing it's custom ASIC territory.
Really? Medical ultrasound has a long history predating high-end GPUs. Maybe that kind of computing power is required for modern high-resolution/low-lag devices, but my guess is you could get something usable with a computer as powerful as a RPi.

- daemin 11y agoI can confirm that you can turn ultrasound data into a 2D image using a simple mid 2000's era ARM processor and an FPGA. So a RPi can even be overkill for that purpose.
