ABSTRACT:
This therapy simulator contains a radiation source (1) in a radiator head. An image acquisition unit (7) is connected to the radiator head and can be swivelled jointly with the latter about a patient's couch (9). At least two diaphragm systems, arranged offset in the direction of the principal axis (2) of the radiation source (1), are arranged in the radiator head. At least one of these diaphragm systems is designed as a depth diaphragm system (4) and at least one other is designed as a measuring diaphragm system (5).
A therapy simulator is to be created on which, together with the setting of the measuring diaphragm, the corresponding depth diaphragm is adjusted automatically. This is achieved by the actuating elements of the at least two diaphragm systems being designed such that the diaphragm systems projected into the image plane of the image acquisition unit (7) move at the same speed.
