Is Your Ultrasound R & amp;D Team Exposed to Harm?
This article collates and simplifies the main points to the level of detail needed by a team manager. It also points to more in-depth resources for those who might need them.
Background on Ultrasound Physics
Firstly, letâs talk a bit about what an ultrasound machine actually does. Most ultrasound machines are diagnosticâthey are intended to inform a healthcare practitioner of internal health issues not visible from the outside. Fun fact: the first ultrasound machines were actually developed for identifying flaws within metal beams, and medical applications came later.
Whether used for health or metallurgy, a diagnostic ultrasound device works by emitting ultrasound (that is, sound waves at a higher frequency than humans can hear) into something, and reading (i.e., listening to) the time-delayed response. Basically, they are a fancy speaker/microphone combo.
To get an idea of how this works, imagine standing near the side of a building with your eyes closed and clapping your hands, then listening for the echo. With a bit of practice, you could probably tell (based on how long the echo takes to reflect) roughly how far away the building is. Thatâs all a diagnostic ultrasound machine does: it tells you how far away things are. The only difference between an ultrasound machine and our clap-listen method is that ultrasound machines use an array of speakers (dozens of pairs of hands) and an array of microphones (dozens of pairs ...
