RESUMO
@#Abstract: Objective To follow up and evaluate the stability testing status of γ stereotactic radiotherapy system (hereinafter γ knife WS 582-2017 Specifications for Testing of Quality Control in X and γ referred to ) in medical institutions based on the RayStereotactic Radiotherapy System WS 582-2017 Methods (hereinafter referred to ). A total of 43 medical institutions using γ knife and 54 medical physics personnel were recruited as the research subjects by random sampling method. Based on the - - standard tracking evaluation method, we followed up the evaluation of γ knife stability testing based on WS 582 2017. Results - Only 66.7% of the 54 subjects preformed WS 582 2017 in their daily work. Only 30.2% (all were tertiary hospital) of 43 medical institutions were equipped with complete quality control and testing equipment. The implementation rate of γ knife stability test was 67.4%, and it was not carried out in strict accordance with the test events and test cycle requirements - specified in the WS 582 2017. There were incomplete test events, incomplete records or test cycles that did not meet the Conclusion standard requirements in γ knife stability test. Medical institutions did not carry out γ knife stability tests in strict - accordance with the projects and cycle required by the WS 582 2017. The reasons are related to medical institutions are not equipped with complete testing equipment, the personnel are lack of understanding of relevant national standards, the poor publicity and implementation of the standards, the lack of standardized training channels and inadequate health supervision.
