I used to work in a cardiology department.  There has been much work using ultrasound to create 3D images of the heart.  Similar systems are used for oil exploration.  I have worked with the reconstruction algorithms.  It is not that difficult.  I'd volunteer to work on it if someone provided me with useful data. 

You don't need sophisticated custom circuitry or DSPs if you are not picky of how fast your image refreshes.
