Effects of Ultrasounds

Ultrasound is an important function of the technology used in today's world. The medical community uses ultrasound and X-rays in everyday life. Ultrasonic waves are high frequency sound waves, ultrasonic waves generate sound waves, these sound waves are injected into the body to generate echo echoes, these echoes can be recorded and the structure under the skin can be seen . There are thousands of ultrasounds that help you see certain diseases and conditions that doctors and patients can not see. However, ultrasound is good for people, but many people doubt whether ultrasound has a negative effect.

Fetuses are not the only ones that can be devastatingly affected by ultrasound. One of the most famous effects of ultrasound is that it tends to heat the tissue as ultrasound passes through the tissue. Tissues can be easily heated up to 40 ° C. The heat in the body is usually easily deprived by blood circulation or simply dissipated to surrounding tissues. This mass can be applied to a technique called ultrasonic therapy, this heat is used to stimulate repair of damaged internal tissue. Another well-known effect of ultrasound is cavitation. Cavitation is a small bubble released when exposed to extreme negative pressure. These bubbles can cause cells and tissues to rupture. This effect is used in the form of noninvasive liposuction where adipocytes are destroyed using ultrasound. Although humans can not hear ultrasound, they still cause direct damage to the human ear.

Ultrasonic therapy has been commonly used for soft tissue injury (Speed, 2001). Studies on the effects of ultrasound on body tissues over the past several decades are discussed below. My goal is to review research over the past few years and try to find a definitive and consistent result on the effects of ultrasound. Therefore, especially for treatment of the medial collateral ligament injury, as ultrasound passes through body tissues, they vibrate the particles and convert the acoustic energy into heat. The amount of heat generated is largely dependent on the given strength and energy absorption rate, as well as on specific tissue characteristics such as heat capacity, heat transfer efficiency, tissue distribution and space (Robertson, Ward, Low, and Reed, 2006, P. 266)
