Abstract:: Abstract: CT simulator has the functions such as original coordination positioning and radiotherapy resetting, and it can provide image and cooridiate information for radiotherapy. Through electronic density calibration, tissue inhomogeneity correction is carried out for supporting dose calculation in treatment planning system. With reference to relevant national standards, international guidelines, clinical functions of CT simulator and the practical experience of the center, a set of acceptance and commissioning testing scheme suitable for big bore CT simulator is presented, aiming to guide and assist the newly opened department in conducting comprehensive, safe and feasible acceptance and commissioning tests. The scheme includes the reference methods and tolerance standards of CT simulator machinery, image quality, radiation dose, radiotherapy related items and safety, so as to ensure the safety and accuracy of CT simulation and survival benefits.
