心血管介入手术中，数字减影（DSA）影像和血管内超声（IVUS）影像之间无法进行精确对照，给介入手术造成了很大的影响。鉴于此，本研究开发了一种集成DSA影像和IVUS影像的一体化在线实时分析系统，主要由数据采集模块、DSA影像模块、IVUS影像模块、血管三维成像模块、DSA影像和IVUS影像的联动模块、影像报告模块和传输模块组成。该系统结合DSA影像和IVUS影像，可多方位对血管进行分析处理。临床实践结果显示，该系统能够很好地将DSA影像与IVUS影像进行联动，且联动误差≤1.5 mm，在临床上可以接受；同时该系统也能够很好地实现DSA影像和IVUS影像的血管的分割重建、测量和三维重建等。术者应用该系统可判断是否要对病变血管行介入治疗以及行介入治疗的血管段位置，并能够精确选择支架的大小和对支架进行定位。

Failure to make accurate comparisons between digital subtraction (DSA) images and intravascular ultrasound (IVUS) images had big inlfuence on cardiovascular interventional operations. In view of this, an integrated online real-time analysis system was developed, which integrated DSA images and IVUS images and mainly consisted of the data acquisition module, DSA image module, IVUS image module, three-dimensional vascular imaging module, DSA-and-IVUS-image linkage module, image reporting module and image transmission module. In combination with DSA images and IVUS images, the system could make blood vessels analyzed and processed in an all-round way. According to the results of clinical practices, the system realized excellent linkage between DSA images and IVUS images with errors ≤ 1.5 mm, which was acceptable clinically. Meanwhile, it also could realize segmented reconstruction, measurement and three dimensional reconstruction of DSA images and IVUS images. With utilization of the system, interventional heart doctors could identify whether interventional treatment was necessary for pigmented blood vessels as well as the position of interventional treatment. Moreover, it could help interventional heart doctors to select the accurate stent size and position the stent.
