Abstract

The invention relates to a high frequency radiation therapy apparatus permitting therapy on the lying patient and which is constructed in such a way that a high frequency generator with a waveguide is displaced in the vicinity of the lying surface of a patient on a couch. The waveguide used is subdivided into a plurality of separately operable groups to obtain a lateral power distribution. Each group has slot-like openings in the wall current area of the waveguide and the openings of each group can be closed independently of one another.
