Abstract :
Therapeutic ultrasound refers generally to any type of ultrasonic procedure that uses ultrasound for therapeutic benefit. This includes HIFU, lithotripsy, targeted ultrasound drug delivery, trans-dermal ultrasound drug delivery, ultrasound hemostasis, cancer therapy, and ultrasound assisted thrombolysisIt may use focused ultrasound (FUS) or unfocused ultrasound. Ultrasound is a method of stimulating the tissue beneath the skin s surface using very high frequency sound waves, between 800,000 Hz and 2,000,000 Hz, which cannot be heard by humans. Your therapist will select a small surface area to work on for anywhere from five to 10 minutes. Gel is applied either to the transducer head or to your skin, which helps the sound waves evenly penetrate the skin. During your ultrasound therapy treatment, your therapist will continually move the transducer head over and around the selected area. Ultrasound therapy is deemed safe by the FDA provided it is performed by a licensed person and provided the therapist keeps the transducer head moving at all times. If the transducer head remains in one place for too long, there is potential to burn the tissues underneath, which you may or may not feel. and The Heat transfer in this Physiotherapy devices is radiation.
