摘要： 虽然MRA血管图象摄影技术提供了一种非侵袭性的观察人体内部血管信息的方法．但是受核磁共振摄影原理的限制，难以像使用造影剂的X线CT一样。来准确地抽取特定血管的信息。针对MRA图象的特点，提出了一种从3维图象数据中检出并追踪特定血管的方法．

Abstract: Although the new technology of magnetic resonance angiography (MRA) provided a noninvasive way to show the information of flood vessels of human body. due to tile scanning limitation of the principle of MRA we can not extract a desired particular vessel like we do it easily by using X—ray CT scan with invasive contract agents.In this paper. we provided a novel method to extract and trace foe desired vessels from a set of three dimensional image data.
