除了 3D MR 血管造影的可视化之外，还进行了进一步分析，以获得解剖相关的广义锥体表达中的血管形状，这适用于手术模拟的目的。采用数学形态学方法对 3D 二值和灰度数据进行定量血管形状分析和处理。作为全局和局部血管形状的定量描述符，模式谱被应用于检测动脉瘤和狭窄等异常血管形状。并采用半径估计和细化的 3D 方法来重建脉管系统。使用体模和临床 MRA 数据检查这些分析和处理程序。
Beyond visualization of 3D MR-Angiography, further analysis has been carried out to obtain vascular shape in an anatomically-relevant generalized cone expression, which is suitable for the purpose of surgical simulation. Methods of mathematical morphology were employed for quantitative vascular shape analysis and processing in 3D binary and grayscale data. As a quantitative descriptor of global and local vascular shape, pattern spectrum was applied to detect abnormal vascular shapes like aneurysm and stricture. And 3D methods of radii estimation and thinning were carried out to reconstruct the vasculature. These analysis and processing procedures were examined using phantoms and clinical MRA data.
