数字X线摄片机质量控制研究

Analysis of Quality Control in Digital X-ray System

为对无锡地区某三甲医院6台数字X线摄片机设备进行质量控制检测,依据省计量标准使用FLUKE仪器进行检测,检测内容包括:球管电压、曝光时间、空气比释动能和半价层。结果显示,此6台DR设备普遍情况良好,除曝光时间合格率为88.89%以外,其他指标合格率均为100%。通过各方面的质控检测,为建立一套完整的DR质控标准打下基础。

Object Conduct the quality control（QC） of six digital X-ray systems（DR）. Method Detect tube voltage, exposure time, air kerma and half value layer based on standard measurement of Jiangsu Province by FLUKE. Result Qualified rate is 100% expect exposure time. Discussion establish whole standard of QC in DR by all aspects detection.
