Abstract		An alternative to standard short target-skin distance (TSD) rectal irradiation techniques is presented. The proctoscopic rectal cone is linked outside of the patient to a superficial X ray tube operated at 50 kVp and 25 mA. The cone is rigidly held in place by a hydraulic clamp and linked to the X ray tube with an electromagnetic lock. The X ray beam is filtered by 0.3 mm of aluminum, giving a half-value-layer of 0.27 mm of aluminum and an exposure rate of 720 R/min. (0.186 C/kg-min.) at the treatment TSD of 22 cm. The physical aspects of the technique are described in detail.
