目的了解车载式医用诊断X射线机(以下简称“车载X射线机”)影像质量控制和放射防护情况。方法以珠三角某市19家医疗机构共26台车载式医用诊断X射线机为调查对象,对其影像质量控制和放射防护检测项目进行评价。结果 2015年珠三角某市26台车载X射线机影像质量控制检测结果全部达标;放射防护检测关键检测点合格率如下:车身右边隔断墙(87.5%)、车身左侧(88.0%)、车身右侧(96.0%)、车身左侧门(87.5%)、车身右侧门(80.0%)、车身后门(83.3%)。结论放射诊疗单位应加强和改善车载式X射线机的放射防护效果,卫生监督管理部门应提高执法力度。
Objective To understand the image quality control and radiological protection of vehicle-mounted medical diagnostic X-ray machines (hereinafter referred to as “X-ray radiographs”). Methods Totally 26 vehicle-mounted medical diagnostic X-ray machines from 19 medical institutions in a city of Pearl River Delta were selected as the research object to evaluate the quality control and radiation protection testing items. Results In 2015, 26 X-ray image quality control tests of X-ray radiographs in a certain city of PRD were all achieved. The pass rate of the radiological testing key test points was as follows: the right partition wall (87.5%), the left side of the car body (88.0% (96.0%), the left side of the body door (87.5%), the right side of the body door (80.0%), the body back door (83.3%). Conclusion Radiological diagnosis and treatment units should enhance and improve the radiological protection effect of X-ray radiography in vehicles, and the health supervision and administration department should enhance law enforcement.
