Abstract
To provide ultrasonic cleaning of inanimate objects, ultrasonic waves in a frequency range of between 15 kilohertz and 10 megahertz are applied to water in a tank with a power density between 15 and 7,000 watts per square centimeter. Asymmetric power waves are applied to avoid instability leading to transient cavitation. To provide ultrasonic treatment of animals, ultrasonic waves in a frequency range of between 15 kilohertz and 500 kilohertz are applied to water in a tub with a power density between 0.1 and 5 watts per square centimeter. The equipment is able to apply ultrasonic waves with at least two power densities in the vicinity of the portion of the animal with one of said power densities being more than 15 watts per square meter for sterilizing the water before the patient enters the tub and the other being less than 15 watts per square meter.
