Wave: The generator of ultrasonic wave is nothing but an oscillator‚ which can generate these high frequency waves. The ultrasonic waves can be produced by the following methods. a) Magnetostriction Generator b) Piezoelectric or Ultrasound Generator a) Magnetostriction Effect This effect is very useful in generating ultrasonic waves are known as Magnetostriction effect. This effect was first discovered by Joule in 1847 & subsequently used by G.W Pierre in an oscillator

History‚ Use and Safety of Ultrasound Introduction Ultrasound is the generation of energy using sound wave of about 20‚000 or more vibrations per second. The ultrasound is mostly used in imaging tools and particularly in medical diagnosis. The ultrasound uses sound waves that are above the frequency of the human ear. A transducer is used to give off the sound waves that are reflected back from the tissues‚ and organs giving a picture of what are inside the body. This is later drawn on
