摘　　要：目的分析介入放射诊疗的数字减影血管造影X射线设备(以下简称DSA设备)的放射卫生设备检测报告中的近台操作透视防护区检测平面上周围剂量当量率在验收检时的测情况和同一台设备的历年变化,针对近台工作人员受照剂量率与防护设施防护量的变化,进行讨论并提出建议。方法通过统计广州南方医大医疗设备综合检测有限责任公司近年来新验收的DSA设备和同一台设备三年间变化的透视防护区检测平面上周围剂量当量率,分析统计数据是否满足《医用X射线诊断设备质量控制检测规范》(WS 76—2020)的要求。结果新验收设备均能满足WS 76—2020要求,其中规范上所述的第二术者位的腹部位置的周围剂量当量率是其中较高的,同一设备连续三年的检测结果大部分未发生剧变。结论应加强关注第一术者位以外的其他近台工作人员的辐射防护量,要注意防护设施的日常维护和管理,增加个人防护用品的使用并增强个人防护意识,降低工作人员的受照剂量。Objective Through the analysis of the radiological health equipment inspection report of digital subtraction angiography X-ray equipment(DSA equipment)used for interventional radiology diagnosis and treatment,the change of the ambient dose equivalent rate of the fluoroscopic protection area detection plane in the acceptance test and the same equipment over the years.To put forward discussions and suggestions.Methods According to the statistics of DSA equipment newly accepted by Guangzhou Southern Medical University Medical Equipment Comprehensive Testing Co.,Ltd.in recent years and the dose equivalent rate of the same equipment on the X-ray protection area detection plane changed in three years,the statistical data were analyzed to meet the requirements of WS 76-2020"Quality Control Test Specification for Medical X-ray Diagnostic Equipment".Results All the newly accepted equipment could meet the requirements of WS 76-2020,among which the surrounding dose equivalent rate of the abdominal position of the second operation mentioned in the specification was the highest.Most of the test results of the same equipment for three consecutive years did not change drastically.Conclusion It is necessary to pay more attention to the radiation protection amount of the staff near the station other than the first operation,pay attention to the daily maintenance and management of the protective facilities,strengthen the use of personal protective equipment and strengthen the awareness of personal protection,and reduce the exposure dose of the staff.
