目的:调查了解原某军区部分医院医用诊断X线摄影(CR/DR)项目放射防护和质量控制现状,发现问题,提出有效改进措施。方法:抽取原某军区部分医院的医用X线摄影(CR/DR)项目,对其放射防护和质量控制相关情况进行分析,调查内容包括:辐射防护设施、图像质量、工作场所辐射泄漏水平、X线管头性能等。结果:最常见的不合格指标有:工作状态指示灯、光野与射野的偏离、图像均匀性等,其合格率分别是73.81%、54.76%和89.74%。结论结论:应在安全防护设施、设备维修与保养等方面进一步加强,并应坚持周期性的放射防护与质量控制监督监测。
OBJECTIVE: To investigate the status quo of radiological protection and quality control of medical diagnostic radiography (CR / DR) projects in some hospitals of the former military region and find out the problems and put forward effective measures for improvement. Methods: The medical X-ray photography (CR / DR) project of some hospitals in the former military region was extracted and the radiological protection and quality control were analyzed. The investigation contents include radiation protection facilities, image quality, radiation leakage level in the workplace, X Line head performance and so on. Results: The most common unqualified indicators were working status indicator, deviation of light field and field, uniformity of images, etc. The pass rates were 73.81%, 54.76% and 89.74% respectively. Conclusions: It should be further strengthened in the aspects of safety protection facilities, equipment maintenance and repair, etc., and periodic radiation protection and quality control supervision and monitoring should be adhered to.
