Radiotherapy CT Simulator-functional Performance And Test

Given that appear on the market at present used in radiotherapy simulation location of CT simulator, because no industry standard for the equipment in our country, the market access of reason for this type of equipment can only to diagnose the industry standard requirements of the device with computer tomography for detection, can be diagnosed by computed tomography(CT) scanning device focus lies in the performance of the image, and the emphasis of the radiotherapy CT simulator is to simulate the precision of positioning, due to the emphasis of the application of both is different, so the test project indicators are also different, therefore, especially for radiotherapy CT simulator to develop the performance requirements and test methods.To ensure the safety and effectiveness of this device.In this paper, from the bed, frame, laser positioning, positioning for the patient as the positioning accuracy, dose, the X-ray generator, image performance, software function, running noise several considerations, introduces the validation radiotherapy CT simulator performance requirements and test methods.The method is suitable for radiotherapy CT simulator, which has the function of simulation positioning CT scanners can reference to use.The performance requirements and test methods in the article is finalized after with the ministry of health Beijing hospital, Chinese academy of medical sciences and other professional radiotherapy doctors and philips(China) investment co., LTD., aerial wei ge medical systems co., LTD and manufacturers of repeated communication meetings to discuss feasibility and practical verification, this requirement is to ensure that meet the demand of clinical use and both manufacturer established on the basis of technical ability, the consumer, manufacturing, testing for approval.
