Abstract

A therapy apparatus for locating and treating a zone situated in the body of a subject life form with ultrasound includes an ultrasound transducer which can be optionally operated in a therapy mode or a locating mode, and which generates therapeutic ultrasound waves having a first frequency focused onto a zone of action in the therapy mode and generates diagnostic ultrasound having a second frequency in the locating mode. The ultrasound transducer also receives portions of the diagnostic ultrasound reflected in the body of the subject in the locating mode and converts them into electrical signals that are supplied to an evaluation electronics which provides image information about the zone to be treated.
