适用于医用光电X射线图像增强器，作为诊断X射线设备的部件。描述了一种通过分析单γ射线光子闪烁脉冲高度谱来确定X射线像增强器探测量子效率（DQE）的方法。这个 该方法仅适用于输出辐射衰减率约等于或快于P-20磷光体的电光X射线像增强器。

Applies to electro-optical X-ray image intensifiers for medical use, as components of diagnostic X-ray equipment. Describes a method of determining the detective quantum efficiency (DQE) of X-ray image intensifiers by analysis of the single gamma-ray photon scintillation pulse-height spectrum. The method applies only to electro-optical X-ray image intensifiers having output radiance decay rates approximately equal to or faster than that of a P-20 phosphor.
