Abstract
A method for controlling an ultrasonic hyperthermia treatment apparatus is disclosed. The hyperthermia treatment apparatus utilizes ultrasound that is focused at a focal spot. The position of the focal spot relative to the transducer is varied, where the peak power of the focal spot and the degree of overlap between the various positions of the focal spot are such that the energy radiated during a shot at each point in the region scanned by the variation of the position of the focal spot represents an equivalent focal spot where the energy applied to the object to be treated is substantially equal to the energy needed to destroy the cell tissue.
