I think it's worthwhile pointing out that the warning isn't against taking necessary ultrasounds, but unnecessary ones. And if there's a tiny risk from an unnecessary procedure, then why take it? And the concern with the device in the link is that it's an unregulated ultrasound device which could, in the hands of someone well-meaning but ill-advised, deliver a dose of ultrasound far in excess of that deemed safe by regulators.

The usual comment we hear on usage of this is that OSH equipment like a simple hammer would have to present a disclaimer such as "Can be fatal if used wrongly -- bashing one's head with this device may prove dangerous" - but doesn't bring a lot to the debate. That being said, open source medical hardware is quite a new field, and lot of aspects need to be matured.
