Abstract

An ultrasound therapy apparatus having an applicator. The applicator comprises at least one ultrasonic beam emitter, at least two ultrasonic transducers, and a support member. The beam emitter emits an ultrasonic beam onto an object within a patient, for the purpose of treating the object. The transducers apply ultrasonic beams to the patient and detect ultrasonic echoes coming from the patient, thereby to form two tomograms, each of a selected plane of the patient, one plane intersecting with the other on a line passing through a region in which the beam emitted by the beam emitter is focused. The support member supports the beam emitter and the transducers in a specific positional relationship. Receivers receive echo signals corresponding to the ultrasonic echoes. Two displays display tomograms formed from these echo signals. They also display a first marker, which indicates a region in which the ultrasonic beam emitted from the beam emitter is focused, and also a second marker, which represents an intersection line of the two planes. By referring to these markers, an operator can set the applicator in a position whereby the beam emitted from the beam emitter is focused onto the object.
