| 英文摘要 | 栓塞治疗是非手术肿瘤治疗方法的首选方案,血管栓塞后的肝癌大部分瘤体组织因缺血、缺氧而逐步坏死,而正常肝组织的供血受影响不大,且能形成侧支循环,不会导致明显的肝功能障碍。假定肝实质组织由距离其最近的血管供血,提出一种肝脏血管栓塞治疗的计算机仿真方法,选用一种精确的欧氏距离变换算法,在改进算法步骤之后,使得该算法支持多背景点。实验结果表明,该方法可以将血管栓塞的结果,映射到肝实质组织中,达到肝实质的栓塞显示效果,能够帮助医生直观地观察栓塞后肝脏组织的供血状况,评估栓塞效果。; Embolization treatment is a kind of knubbly and non-operative treatment method.It's recommended as the best method in various kinds of non-operative treatments.The embolization treatment stops the hepatic artery from providing blood.As a result,the tumors will die from lacking of blood and oxygen,but the blood supply of normal liver tissue wouldn't be significantly affected.Assume the liver parenchyma is supplied by its recent organization blood vessels,and propose a kind of computer simulation method of liver vein embolization treatment,choose a precise Euclidean distance transformation algorithm.After improving the algorithm,it can support not only single background.Experiment shows that this method can get results of embolization map to the liver parenchyma organization,achieving the embolization display of liver parenchyma.So it can help the doctor intuitively observe the blood-supply condition after embolization,and then evaluate the effect of the embolization treatment.; 国家自然科学基金项目(60701022) |
