True, but ultrasound isn't entirely benign. Depending on what frequency and what power it can crack solid parts of the body (its used to break up kidney/gall stones) it also can heat things up (which is, assuming my understanding is correct, why doppler scans for blood flow are not done on <18 week pregancy)
