Abstract

The method of functional imaging is applied to x-ray angiograms. Functional images are generated by inserting at each point of an x-ray image a computed grey or colour value proportional to a dynamic parameter (such as blood velocity) instead of the recorded x-ray absorption value. For this purpose a new system for angiographic image processing has been developed. First results show that the method which we have called Computer Angiography is a tool to extract more information about the blood dynamics in organs in an easier and faster way than with the conventional angiographic technique.

摘要

功能成像方法应用于X射线血管造影图。通过在X射线图像的每个点插入与动态参数（如血流速度）成比例的计算出的灰度值或彩色值，而不是记录的X射线吸收值，来生成功能图像。为此，已经开发了一种用于血管造影图像处理的新系统。初步结果表明，我们称为计算机血管造影的方法是一种比传统血管造影技术更简便、更快速地提取有关器官血液动力学更多信息的工具。
