Scope

This standard applies to radiotherapy simulators (hereinafter referred to as simulators) that use diagnostic X-ray equipment to simulate the geometric conditions of radiotherapy radiation beams, determine the irradiated treatment volume, the position of the radiation field and the size of the radiation field during radiotherapy. This standard applies to simulators using high-voltage generators that meet the requirements of GB 9706.3-1992 and whose working voltage does not exceed 400kV. This standard is only applicable to radiation therapy simulation test before radiation therapy, not for other purposes, such as diagnosis. A simulator conforming to this standard consists of the following components: a system capable of generating X-rays not exceeding 400kV, used to simulate the geometric conditions of radiotherapy radiation beams; a system capable of generating transmitted X-ray images by means of photographic perspective; A device that can define the size of the radiation beam and define the treatment area; a mechanical structure that can actually simulate the geometric conditions of the radiotherapy equipment and its movement, and can support the imaging system; a treatment couch. Equipment to which this standard applies must be used under the supervision of qualified personnel. Unless otherwise stated, the radiation therapy simulators targeted by this standard have an isocentric gantry with no pitch and swing of the radiation head. During any test, only those controls normally accessible to the operator are permitted to make adjustments to the simulator, and such adjustments are considered part of the normal operation of the simulator.
