Abstract
Abstract A supersonic hyperthermia treating method comprises the steps of inserting a heat generating member having a high attenuation for supersonic waves into a diseased part in a body and leaving it there, then transmitting supersonic waves generated outside of the body from a supersonic wave generator for heating the heat generating member to hyperthermically treat the diseased part.
