摘要

本文介绍了用冠状动脉造影图像测量冠状动脉血流的实验验证。在两组冠状造影图像上沿动脉横切线测量图像强度:一组是标准注射造影剂，另一组是少量缓慢注射造影剂。采用简单动脉模型进行实验验证。流量计算的初步结果表明，误差在19%以下。

Densitometric measurements in coronarographic images for blood flow estimation

The paper presents the experimental validation of the coronary blood flow measured from coronarographic images. Measurements of the image intensity along the cross-section lines of the artery were performed on two sequences of coronarographic images: one with the standard injection of the contrast and the second one with the small quantity of slowly injected contrast. Experimental validation was performed using a simple artery model. The preliminary results of the flow calculation show that the error is below 19%.
