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) coition oftenness sound shake and echoes. thither be distinct kinds of echography they argon placoid image, 3D sonography imagining, and Doppler ultrasound. Doppler ultrasound is based on the Doppler act. (Doppler effect is whenever relative motion exists amongst a source of sound and a listener and the absolute frequence of the sound heard by the listener sounds different compared to the frequency when there is no motion.) The frequency of the echoes depend on how the mark reflecting the ultrasound waves is locomote. If it is a high frequency then it is moving toward the probe and if it is a subvert frequency it is moving forward from the probe. How much the frequency changes depends on how fast the object is moving. TO organize how fast and object is moving, Doppler ultrasounds broadside the change in frequency of the echoes. Doppler ultrasound is utilize to footprint the rate of blo od light 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 engender a 3D image. 3D-ultrasound imaging is used to feature 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 cosmos born to mother s who had many ultrasound examinations durin! g pregnancy. There are deuce 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...
