The Development of a New Stereotactic Whole Body Frame for Extra-Cranial Radiotherapy


We have been researching an upgraded version of a stereotactic whole body frame, which is used to evaluate the daily setup accuracy of the patient position and to reduce the amount of tumor movement produced by breathing during fractionated extra-cranial radiotherapy. The aim of this study was to develop a new whole body frame, with less setup error whilst being able to repositioning the patient. The dimensions of the frame were 130 cm in length, 50 cm in width and a base plate thickness of 3 cm. The material used in the base plate of the frame was bakelite and the immobilizer was made from acetal. In addition, Radiopaque angio-catheter lines were engraved on the base plate using a coordinate system, which determined the target localization. Using the above methods, a frame that is suitable for CT simulation and treatment was manufactured. The frame structures was designed to minimize collisions relative to the change sin the rotation angle of the gantry and to maximize the transmission rate of the incident radiation at the lateral or posterior of the oblique direction. The attach verification device, such as X-rays and Fluoroscopy, to the new body frame were satisfactory and practical with respect to most functions such as immobilization, target localization, reducing the treatment setup error and verifying the delivered dose
