This paper reports the status of a new cardiovascular fluoroscopy benchmarking phantom. A joint working group of the Society for Cardiac Angiography and Interventions (SCAI) and the National Electrical Manufacturers Association (NEMA) developed the phantom. The device has been adopted as NEMA standard XR 21-2000, 'Characteristics of and Test Procedures for a Phantom to Benchmark Cardiac Fluoroscopic and Photographic Performance' in August 2000. The test ensemble includes imaging-field geometry, spatial resolution, low-contrast iodine detectability, working thickness range, motion unsharpness, and phantom entrance dose. The phantom tests systems under conditions simulating normal clinical use for fluoroscopically guided invasive and interventional procedures. Test procedures rely on trained human observers.
本文报告了一种新型心血管荧光透视基准模型的情况。心脏血管造影与介入学会（SCAI）和美国国家电气制造商协会（NEMA）的一个联合工作组开发了该模型。该设备于2000年8月被采纳为NEMA标准XR 21 - 2000，即“用于心脏荧光透视和摄影性能基准测试的模型的特性及测试程序”。测试项目包括成像视野几何形状、空间分辨率、低对比度碘可探测性、工作厚度范围、运动模糊以及模型入口剂量。该模型在模拟荧光透视引导下的侵入性和介入性程序正常临床使用的条件下对系统进行测试（检测）。测试程序依靠经过培训的人员进行观察。
