一、按照工作方式确定检定项目依据JJG744-2004《医用诊断X射线辐射源检定规程》,医用诊断X光机分为连续工作方式和间歇工作方式,就是平时所说的透视和拍片。JJG744-2004适用于胃肠机、摄片机、牙片机、C形臂、床旁机的检定。有的X光机(如胃肠机)具有透视和拍片两种功能,应分别进行检定。透视机检定项目包括辐射输出的空气比释动能率、辐射输出的质(手动模式)、分辨力、射线管电流、射线管的焦点。摄片机检定项目 First, in accordance with the work to determine the test items JJG744-2004 “medical diagnostic X-ray radiation source verification procedures”, medical diagnostic X-ray machine is divided into continuous work and intermittent work, is usually said perspective and filming. JJG744-2004 for gastrointestinal machines, film machines, tooth machine, C-arm, bedside machine test. Some X-ray machine (such as gastrointestinal machine) with perspective and film two functions, should be tested separately. The fluoroscopy program includes the air-kerma rate of radiation output, the quality of the radiated output (manual mode), resolution, tube current, and the focus of the tube. Camera test items
