《GB/T 19042.3-2005医用成像部门的评价及例行试验 第3-3部分:数字减影血管造影（DSA）X射线设备成像性能验收试验》由TC10（全国医用电器标准化技术委员会）归口，TC10SC1（全国医用电器标准化技术委员会医用X射线设备及用具分会）执行，主管部门为国家药品监督管理局
GB/T19042的本部分适用于带有成像系统的数字减影血管造影设备中影响影像质量的那些x射线设备部件。该成像系统由X射线发生子系统及探测设备组成。该探测设备由x射线影像增强器电视链，数字化和数字影像的处理方法，影像存储和包括减影的影像操作，以及影像显示设备组成。本部分不适用于普通数字成像设备。如果此类设备具有数字减影血管造影功能，则本部分仅限于数字减影血管造影功能。

Scope

This part of GB/T 19042 applies to those X-ray equipment components that affect image quality in digital subtraction angiography equipment with imaging systems. The imaging system is composed of X-ray generation subsystem and detection equipment. The detection equipment is composed of an X-ray image intensifier TV chain, digitization and digital image processing method, image storage and image operation including subtraction, and image display equipment. This section does not apply to ordinary digital imaging equipment. If such equipment has a digital subtraction angiography function, this section is limited to the digital subtraction angiography function.
