Abstract

Background . Ultrasound occupies an important place among many therapies in physiotherapy. The process of ultrasound treatment in physiotherapy consists of the contact interaction of the ultrasonic emitter with the surface of the skin of the patient's body. The issue of patient safety remains relevant to this procedure. Thus, in everyday clinical practice deviations of the accuracy of the initial acoustic parameters of the ultrasound apparatus from the nominal ones were observed. This can either lead to an inadequate effect of the ultrasound on the patient's body or may lead to an excessive effect of the ultrasound on the patient. In the first case, the patient does not receive the necessary dose of ultrasound for treatment, and as a consequence, ineffective treatment and disappointment of the patient in this method of treatment may be observed. In the second case, there is a risk of injury to the patient, which poses a threat to the safety of his health during the procedure of ultrasound therapy. Objective. The purpose of the paper is development of a technique for evaluating the initial parameters of ultrasound therapy apparatus for practical application in the development and improvement of ultrasound therapy apparatus. Methods. The study measured the input and output parameters of a piezoelectric element that is included in the emitter of the experimental ultrasound therapy apparatus. Results. As a result of these studies, a calculation technique was developed and the value of the ultrasound intensity of the test unit of the adaptive ultrasound therapy apparatus was determined. Conclusions. A technique for calculating the initial intensity of ultrasound for ultrasound therapy apparatus has been developed, which makes it possible to use them in the development of new ultrasonic emitters for physiotherapy.
