[Development of new positioning and adjustment aids for fractionated whole body irradiation using compensators].

A new system of positioning and adjustment facilities is presented for fractionated total-body irradiation with the use of compensators, consisting of a positioning plate provided with devices for translation and rotation, a lifting device installed in the irradiation room, a transport vehicle, an individually adapted foam bed for the patient, and a fine-adjustment holding device for the compensator. The method as well as the material used are described in detail. The system does not only allow an exact reproduction of patient's position and compensator adjustment, but also reduces the time of preparation.
