A therapy apparatus for locating and treating a zone in the body of a living subject with focused, therapeutic ultrasound waves having a first frequency includes an ultrasound locating system which emits diagnostic ultrasound having a second frequency, and which receives parts of the diagnostic ultrasound reflected in the body of the subject and converts them into electrical signals which are used to form an image of the zone to be treated with the subject. In order to permit the locating system to be operated simultaneously with the generation of therapeutic waves, and thus to be able to generate a continuous image without disturbances caused by therapeutic waves, the electrical signals are supplied, before forming the image, to a filter having a transfer function with a rejection band wherein the first frequency lies and a passband wherein the second frequency lies. The output signals from the filter are then used to generate the image.
