医用数字摄影(CR、DR)系统X射线辐射源是一种医院临床诊断用的强制检定计量器具。评估CR、DR的安全性和有效性对保证患者和医务工作者的生命健康安全有着非常重要的意义。而CR、DR最重要的安全指标就是空气比释动能。因此,分析与评定CR、DR空气比释动能的测量不确定度十分必要。一、检定依据与测量模型本文选用RS2000C型号的诊断水平剂量仪和100mm长杆电离室,依据JJG1078-2012《医用数字摄影(CR、DR)系统X射线辐射源检定规程》和
Medical digital photography (CR, DR) system X-ray radiation source is a hospital clinics for the diagnosis of mandatory testing measuring instruments. To assess the safety and effectiveness of CR and DR is very important to ensure the health and safety of patients and medical workers. The CR, DR the most important safety indicator is the air kerma. Therefore, it is necessary to analyze and evaluate the measurement uncertainty of the kinetic energy of CR and DR air. First, the test basis and measurement model This selection of the RS2000C type diagnostic level dosimeter and 100mm long pole ionization chamber, according to JJG1078-2012 “medical digital photography (CR, DR) system X-ray radiation source verification procedures” and
