I have never heard of this being an issue for diagnostic ultrasound. Since I’m trained in (cardiac) ultrasonography, I think this would have come up... I also did a brief lit search and didn’t identify any obvious examples.

I suspect your wife is referring to therapeutic ultrasound, which can damage bone [1]. But this is not the ultrasound people are getting of their heart, abdomen, or pelvis in general.

Even diagnostic ultrasound has been implicated in foetal brain damage (through cavitation). And ultrasound operators are known to often suffer from damage in their dominant hand.

Do you have a citation for this? I don't see anything about it in your link.

The comment from memory, but I found this paper:

US Bio effects of diagnostic US are discussed at (painful) length in undergraduate radiography training here in New Zealand. We are fairly well aligned with the UK in our training pathway but in my (limited) experience echo techs don’t seem to come from a radiography background while ultrasound ones do. Could be a local situation though. Broadly, the priciples seem to be ALARM and perhaps don’t do ‘souvenir’ scanning of foetuses. I wonder if anywhere follows that.

Good point, my training excludes fetal ultrasound, so this might be one reason yours and mine differ.

See! I learned something new today! :D
