Abstract
An ultrasound hyperthermia applicator comprises a plurality of transducers which can be operated in different grouping modes so that the applicator is effectively provided with a variable number of elements having variable effective diameters transmitting coherent beams. The individually coherent beams from these elements are individually focused for incoherent superposition in the target volume according to a spiral or multi-spiral focusing scheme. Such an applicator is capable of uniformly heating without scanning a limited part of human body with volume greater than the inherent focal size of the individual transmitter element.
