That's cool. Ultrasound imaging should be much more broadly available, like household object next to your toothbrush. I wonder how OpenWater open-source focused ultrasound stimulation is doing.
Well done, although all commercial ultrasounds are just a probe (piezoelectric curved or linear array) connected to a computer, previously over a high speed custom parallel bus, today USB-C will do. Then M-mode or B-mode reconstruction just runs in software. Doppler needs beam-steering etc and is a bit more complex.
