A method is presented which aids the clinician in obtaining quantitative measures and a three-dimensional (3-D) representation of vessels from 3-D angiographic data with a minimum of user interaction. Based on two user defined starting points, an iterative procedure tracks the central vessel axis. During the tracking process, the minimum diameter and a surface rendering of the vessels are computed, allowing for interactive inspection of the vasculature. Applications of the method to CTA, contrast enhanced (CE)-MRA and phase contrast (PC)-MRA images of the abdomen are shown. In all applications, a long stretch of vessels with varying width is tracked, delineated, and visualized, in less than 10 s on a standard clinical workstation.
本文介绍了一种方法，该方法可帮助临床医生以最少的用户交互从三维血管造影数据中获取血管的定量测量值和三维（3-D）表示。基于两个用户定义的起点，通过迭代过程跟踪血管中心轴。在跟踪过程中，计算血管的最小直径并进行表面渲染，以便对脉管系统进行交互式检查。展示了该方法在腹部CTA、对比增强（CE）-MRA和相位对比（PC）-MRA图像中的应用。在所有应用中，在标准临床工作站上，不到10秒即可跟踪、描绘并可视化一段宽度各异的长血管。
