ABSTRACT:
In a radiation emitting device, particularly in a radiation therapy device, isodose curves are adjusted both by a moveable plate that is controlled during irradiation and by varying the dose rate of the radiation beam during irradiation. By superimposing the effects of moving the plate and varying the dose rate of the radiation beam, it is possible to vary the isodose curve in the object of irradiation, so that a wide range of variation in the possible isodose curves is obtained. If the plate is moved at a constant speed, e.g. various wedge-shaped isodose curves can be easily achieved.
