My obstetrician refused to do ultra-sounds except when medically indicated. She told me that ultra-sound can damage cells and is the same technology used to break up kidney stones.

Sure, if it's focused. That sounds like a pretty lame excuse- Ive never heard of any damage from an ultrasound that wasn't intended. You have to create a focal point where the waves cross, which creates a turbulence at that point only.

I suppose that's possible, at least to some extent. My wife had the same concerns. But that probably has to do with the energy and type of radiation. I'm sure GE's legal department has looked into it.
