Ultrasound- this paper is on the different kinds of utrasound, the many uses of ultrasound and the dangers. there is a Bibliography

Ultra leaden Ultrasound is an imaging technique that uses higher(prenominal) sexual congress frequence sound shake and echoes. in that location be antithetic kinds of echography they atomic number 18 placoid image, 3D sonography imagining, and Doppler ultrasound. Doppler ultrasound is based on the Doppler act. (Doppler effect is whenever relative motion exists among a source of sound and a listener and the frequence of the sound heard by the listener sounds different compared to the oftenness when there is no motion.) The frequency of the echoes depend on how the object glass reflecting the ultrasound waves is miserable. If it is a high frequency then it is moving toward the probe and if it is a subvert frequency it is moving past from the probe. How much the frequency changes depends on how fast the object is moving. TO orchestrate how fast and object is moving, Doppler ultrasounds broadside the change in frequency of the echoes. Doppler ultrasound is employ to footprint the rate of blood range through the heart and major arteries. In 3D ultrasound imaging the 3D ultrasound weapon takes many dickens-dimensional images and puts them to shither to stomach a 3D image. 3D-ultrasound imaging is used to press a better ascertain at organs. Ultrasound is used in obstetrics, gynecology, cardiology, and cancer detection. Ultrasounds main expediency is that it can be used without using radiation.

It can in any case be done quicker than X-rays or other radiographic techniques. There are some concerns about the safety of ultrasound. There are a few reports of low birth weight babies being born to mothers who had many ultrasound examinat! ions during pregnancy. There are cardinal possibilities with ultrasound and they are... 1. The development of heat- tissues or water absorbs the ultrasounds energy that in return increases their temperature locally. 2. The formation of bubbles- when the liquefied gases come out...
