Ultrasound

ultrasound Ultrasound is sound pressure with frequency higher(prenominal) than 20khz; this is the f number frequency limit of human envisioning. Since it is sound, it is a longitudinal loop. some(prenominal) animals such as bats and dogs have the major power to hear sounds with frequency above 20khz like bats and dogs. in that respect ar many human uses of ultrasonography such as in the medical field to observe the personate, ultrasonic interrogatory to mention out the density and work on of materials, echo sounder and ultrasonic cleansing Medical sonography: A transmitter sends Ultrasound waves to the body which then reflects voxs of or undecomposed waves ass where the teleph wizard receiver uses the reflected waves to create an image of the organ or material it has bounced withdraw. It is one of the most widely utilise symptomatic tools in ripe medicine.

Ultrasound can also be utilize to spy abnormalities in the pelvis area. It also employ to treat tumors exploitation a process called Focused Ultrasound Surgery (FUS) or HIFU, High Intensity Focused Ultrasound. unhearable testing: It is a way of testing materials without damaging them in anyway way.

Ultrasonic testing can be used to measure the ponderousness of materials as well as hear flaws in them. An ultrasound transducer connected to a diagnostic work is passed over the object. The waves reflected off the object is receive by the transducer and the diagnostic m achine calculates the shape and thickness de! pending on the amplitude of the wave reflected. The distance of the part the wave reflected of is measured depending on the quantify it takes for the wave to make out back. SONAR(SOund NAvigation and Ranging): sonar is usualy used underwate by boats and submarines as seafaring to detect the shape of the sea bottom or to detect separate vessel. sonar creates a quiver of sound and then listens for reflections of...If you lack to get a full essay, order it on our website: OrderEssay.net
