标准摘要
[中文适用范围]： 规定了确定数字 X 射线成像设备的探测量子效率 (DQE) 的方法，该效率是在医疗应用范围内的工作条件下曝光和空间频率的函数。 [外文原描述]： Specifies the method for the determination of the detective quantum efficiency (DQE) of digital X-ray imaging devices as a function of exposure and of spatial frequency for the working conditions in the range of the medical application as specified by the manufacturer. Is applicable to projection digital X-ray imaging devices producing images in digital format that are used for medical diagnosis. It is restricted to digital X-ray imaging devices that are used for radiographic imaging, such as CR systems, selenium-based systems, flat panel detectors, optically coupled CCD detectors, and digital X-ray image intensifiers used for single exposures.
