ABSTRACT:
An ultrasound hyperthermia apparatus has a tomographic ultrasound probe for obtaining a tomographic image and a heating applicator for heating a tumor portion. A position detector is provided to detect the positional relationship of the tomographic ultrasound probe and the heating applicator with respect to a living organism, and a hot spot detector detects the position of a focusing point, i.e., a hot spot of the ultrasound radiated from the heating applicator in accordance with position data from the position detector, thereby generating an image signal indicating the hot spot. The image signal indicating the hot spot is superimposed on a tomographic image signal, and the hot spot is displayed on a TV monitor together with the tomographic image.
