Described in the paper is a relatively simple method for the determination of the efficiency of registration of X-ray diagnostic systems by the whole tract of transformation of radiation contrast from the spot of contrast-sensitivity test to the visual registration of image. It is just enough to have the contrast sensitivity test and to measure the dose at test location. On the basis of the visually registered minimal contrast the efficiency of registration of a diagnostic system is evaluated by the radiation-contrast parameter. The suggested method can be used at handover tests and in testing the X-ray systems during their exploitation.
本文描述了一种相对简单的方法，用于通过从对比敏感度测试点到图像视觉配准的辐射对比度全变换过程来测定X射线诊断系统的配准效率。只需进行对比敏感度测试并测量测试位置的剂量。基于视觉配准的最小对比度，通过辐射对比度参数评估诊断系统的配准效率。所建议的方法可用于交接测试以及在X射线系统运行期间对其进行测试。
