What is a sonogram machine used for?
Question:
And what occupations use these machines?
Answers:
It's an ultrasound scanner.
It works by sending out a wave of very high frequency sound waves into the body. The sound waves are reflected back from boudaries between fluid and solid matter, where the physics of sound waves affects how the wave travels. The 'echo' is detected by the scanner and displayed graphically on a screen.
Used by radiographers in the UK and ultrasonographers / sonographers in the US.
