It evolved out of defense-oriented electronics devices such as Radar and more specifically Sonar, which uses sound waves. Sonic altimeters operating on pulses of Compressed Air were in use in l934 by what was to become the Luftwaffe and they were installed on commercial Zeppelins such as the Graf Zeppelin and HIndenberg. A sort of variant called the sonicaltimeter ( an early use of run-on language now so common) was made and used on Blimps by the US Navy and was adapted to submarine detection during the war. so it goes.
It is an ultrasound scan.
An ultrasound tech will look for a penis or testicles when checking an ultrasound scan for a body. These parts of the anatomy make themselves very apparent on a scan in males.
Ultrasound scan requirements vary depending on the type of ultrasound. For example, for a pregnancy ultrasound, the woman is expected to drink 4 glasses of water and not relieve her bladder for an hour before the scan.
