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 evolved out of defense-oriented devices such as Radar and Sonar. It is closer to the latter as it uses Ultra ( beyond) sound waves, not radar pulses. You can forget about a round screen and azimuth markings and rings also. They were evolved from Radar and Sonar but are adapted to Medical purposes.
The ultrasound was invented by the English physician Ian Donald in 1957. Today, it is one of the most important pieces of medical equipment in helping to diagnose illneses.

Ultrasound systems were first used in the medical system in the late 1940s and early 1950s. They were based on imaging systems used for material testing in the construction of ships.
First discovered in 1893 by Sir Francis Galton. However an apparatus to utilize it technologically wasn't engineered until 1917, where it was used in submarines.

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.
the ultrasound was invented in california.
