Abstract
Recently, ultrasound is becoming a universal way of treatment when it comes to clinic, The thermal effect of therapeutic ultrasound can raise the temperature of tissue without damage and thus increases the flow rate, and this leads to the oxygen transportation velocity of peripheral tissue and ultimately facilitates the metabolism. The purpose of this research is analyzing relations between PTT and transmission time of therapeutic ultrasound, and in this study the PTT variation due to respective transmission time of ultrasound upon 17 normal persons was measured and as a result, it was observed that PTT increases as transmission time of therapeutic ultrasound.
