Abstract :
Though it is well understood that the success of radiotherapy involves correct treatment simulation and accurate patient positioning, the quality assurance of the radiotherapy simulator receives little attention. A radiotherapy simulator combines the technology from therapeutic and diagnostic radiology and needs to be tested for both. As pre-commissioning quality assurance program, the Varian Ximatron simulator was checked for (i) mechanical and optical parameters; (ii) parameters of X-ray beam; (iii) performance of image intensifier; and (iv) parameters relating to safety and radiation protection. In this paper the authors present the methods adopted and the results of the quality assurance of the Ximatron radiotherapy simulator
