It is perfectly fine in my opinion. The patient can be instructed to move very 
slowely and if 1 or 2 high quality images are transferred that is a huge 
benefit for the physician.

True. I would guess that those are not your standard cases which one would 
likely encounter.

Depends heavily on the case. Doctors are trained to diagnose by talking to 
patients but observing something and comparing it to something one has seen 
before is greatly enhanced by even a few images.

I tend to agree. If a specific use case pops up from people actually doing the 
work those applications can be greatly optimized.
