X线检查的目的在于正确显示检查部位和发现病变,将病变显示在高质量照片上,从而为临床提供可靠的诊断依据。过去我们认为质量保证(QA)和质量控制(QC)是技师的工作,与诊断医师关系不大,许多诊断医师对QA、QC的概念及具体内容都不大清楚,也不去研究,通过近几年我科开展QA、QC活动以来,我们意识到,质量保证和质量控制不单纯是技师的事情,与诊断医师也密切相关。 众所周知,影像诊断不论是X线检查、超声检查、还是核素、CT、MRI,都离不开机器,机器的性能和使用情况与产生的图像密切相关。同一台机器不同的 The purpose of the X-ray examination is to correctly display the examination site and find lesions, and to display the lesions on high-quality photographs, thus providing a reliable diagnosis basis for the clinic. In the past, we believe that quality assurance (QA) and quality control (QC) are the work of technicians and have little to do with the diagnosis of physicians. Many diagnosticians are not very clear about the concepts and specific contents of QA and QC and do not study them. After several years of QA and QC activities in our department, we realized that quality assurance and quality control are not simply technicians, but also closely related to diagnosticians. As we all know, imaging diagnostics, whether it is X-ray examination, ultrasound examination, or radionuclide, CT, MRI, are inseparable from the machine, the performance and use of the machine and the resulting image is closely related.
