&gt; I also think you&#x27;re seriously underestimating the computational cost of converting the measured signal to a usable image. No way is an RPi fast enough to produce a live image with decent quality. 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&#x27;m guessing it&#x27;s custom ASIC territory.<p>Really?  Medical ultrasound has a long history predating high-end GPUs.  Maybe that kind of computing power is required for modern high-resolution&#x2F;low-lag devices, but my guess is you could get something usable with a computer as powerful as a RPi.<p><a href="http:&#x2F;&#x2F;www.ob-ultrasound.net&#x2F;history1.html" rel="nofollow">http:&#x2F;&#x2F;www.ob-ultrasound.net&#x2F;history1.html</a>
