Ultrasonic irradiator for intracavitary treatment

Experimental results and analysis of irradiation intensity distribution in biological tissue under treatment by the ultrasonic irradiator comprised of three piezoplates placed on the lateral surface of 5 mm in diameter medical catheter are considered. It is shown that distribution of irradiation intensity produced by the considered irradiator around the catheter is more uniform than the distribution of intensity produce by two plates irradiator.
