title: [Therapy simulator for radiotherapy planning].
abstract: The ideas prevailing so far with regard to therapy simulators are represented and the type of the simulator used is described; after that, the range of problems a simulator is applied to, is being analysed more detailedly. The use of the simulator is necessary within two phases of irradiation planning: Firstly, to trace that cross-sectional view of the body which is best adapted to dosage planning along with a preliminary adjustment informing upon the beam directions and the field sizes needed. Secondly, to accomplish the final fixation of the needed beam directions and field sizes inclusively the marking of cutaneous fields, a definitive schedule of doses having been laid down before. The requirements, therapy simulators have to meet according to these considerations, are discussed.
