The history of performance testing in Leeds of television fluoroscopic systems is briefly outlined. Using the visual, physical and technological requirements as a basis, a set of nine test objects for quality control in television fluoroscopy is described. The factors measured by the test objects are listed in the introduction; the test objects and their function are fully described in the remainder of the paper. The test objects, in conjunction with a television oscilloscope, give both subjective and objective information about the X-ray system. Three of the test objects enable the physicist or engineer to adjust certain aspects of the performance of the X-ray system. The set of nine test objects is available commercially.
简要概述了利兹对电视荧光透视系统进行性能测试的历史。以视觉、物理和技术要求为基础，描述了一套用于电视荧光透视质量控制的九个测试对象。介绍部分列出了由测试对象测量的因素；本文其余部分对测试对象及其功能进行了全面描述。这些测试对象与电视示波器一起，可提供有关X射线系统的主观和客观信息。其中三个测试对象能使物理学家或工程师调整X射线系统性能的某些方面。这套九个测试对象有商业供应。
