Ultrasound-On-a-Chip

"Will ultrasound-on-a-chip make medical imaging so cheap that anyone can do it?"

Speaking as a radiologist, I think this is a very encouraging development.  It could make it much cheaper to acquire images.

However, getting medically useful images also requires a certain amount of skill (which is why sonographers still need to go to school).  And interpreting them accurately is still non-trivial.  So I don't think "anyone" will be able to do it.  But it could help a lot of people, especially in remote areas or in time-sensitive emergency settings.  (Link via Howard R.)
