[Technics and radiophysics of Buchler's afterloading device]

Informations are given upon a newly developed afterloading apparatus. It works by means of a point-shaped Iridium-192 source which is oscillating within the applicator during irradiation. The motion of the source is regulated by exchangeable cams. A great variation of isodose curves can be obtained in this way. The safety devices of the installation yield optimal radiological protection. The compact construction system of the basic equipment allows flexible use within existing therapy rooms.
