标准摘要
[中文适用范围]： IEC 1223的本部分适用于影响数字减影血管造影（DSA）设备图像质量的X射线设备组件，其成像系统由X射线发生子系统、包含X射线图像的检测装置组成。 INTENSIFIER 电视链、数字化和数字图像处理手段、图像存储和图像操作（包括减法）以及图像显示设施。本标准不适用于数字成像通用设备。如果这样的设备包括DSA功能，则其仅限于DSA功能。 [外文原描述]： Applies to those components of X-ray equipment which influence the image quality of equipment for digital subtraction angiography (DSA) with an imaging system consisting of an X-ray generation subsystem, a detection device comprising an X-ray image intensifier television chain, means of digitization and digital image processing, image storage and image manipulation including subtraction, and facilities for image display. Defines the essential parameters which describe the performance of the above-mentioned components of X-ray equipment with regard to imaging properties, and defines methods of testing whether measured quantities related to those parameters comply with specified tolerances.
