Essay on ultrasound and x rays and the physics involved.
In this essay I will explain about ultrasound and x-rays and talk about how they a put to use in the medical profession. I will talk about the physics involved when putting these technologies to work and also the dangers they may impose if not used correctly.
Ultrasound.
What Ultrasound is a medical imaging technique that basically uses sound waves (which are of a high frequency) and records its echoes. Just like what submarines use to located other ships or submarines (sonar) as well as what bats use to see in the dark.
Ultrasound works in the medical profession by the ultrasound machine transmitting high frequency sound pulse though the body using a probe. The frequency of the sound is about (1 to 5 megahertz). The sound then travels though the body until it hits a tissue boundary for example between fluid and a soft tissue.
Some of these sound waves are reflected back to the probe as other care on going deeper into the body until they also reach another boundary and are reflected back...
