Noticed that the page was pegged for clean up back in Nov. 2005. I've added a section about how ultrasonic testing works as well as cleaned up a bit of wording. I didn't cite references as I got most of the info from watching a demo of an ultrasonic test at work. User:Canuckman55 26 October 2006.

Can anybody add a few words about all those medical applications for ultrasonic testing? Nowadays they usually complement mammographic testing, and mothers-to-be can view their offspring-to-be with the help of this technology. -- Remotelysensed ( talk) 16:24, 7 December 2010 (UTC)NDT-UT2 reply

@ North8000: you added this ref name, but forgot to fill in the source. -- Fyrael ( talk) 20:50, 26 May 2021 (UTC) reply
