数字医学研究与应用 Research and Application of Digital Medicine CTA三维重建的研究与展望 ① ② ② ② 翟争峯 蒲立新 曲建明 高忠军 摘 要 CT血管造影（CTA），又叫非创伤性血管成像技术，是脑血管造影的三大方法—数字减影血管造影（DSA）、CT血管 造影（CTA）、磁共振血管造影（MRA）之一，由于其无创性，完成速度快、分辨率高以及所用造影剂容易通过肾脏排泄等优 点，使CTA在近些年得到飞速发展。CTA三维重建可显示脑血管病变的三维形态，方便了医生从不同的角度观察病灶以及其周 围组织，大大提高了医生的诊断效率与准确性。首先讨论CTA在国内外临床上的应用；其次对CTA三维重建过程中去骨算法进 行阐述，并对去骨后的绘制方法进行简要综述；最后对CTA三维重建未来进行展望。 关键词 CTA 三维重建 去骨算法 Doi:10.3969/j.issn.1673-7571.2014.05.019 [中图分类号] R318.1 [文献标识码] A The Study and Prospects of CTA 3D Reconstruction / ZHAI Zheng-feng, PU Li-xin, QU Jian-ming, et al//China Digital Medicine.-2014 9(5): 64 to 67 Abstract CT angiography (CTA) is also called traumatic vascular imaging techniques, which is one of the three significant approaches-digital subtraction angiography(DSA),CT angiography(CTA), magnetic resonance angiography (MRA) ) in cerebral angiogram. Because of non-invasion, fast speed, high resolution and the contrast agents easily accomplished through renal excretion, etc, CTA has got rapid development in recent years. CTA 3D reconstruction can show three-dimensional shape of cerebrovascular pathological changes, which is convenient for doctors to observe lesions and the surrounding tissue from different angles, greatly improving the doctors diagnosis efficiency and accuracy. In this passage, firstly, we will discuss the clinical application of CTA in domestic and foreign countries, then, we will state bone removal algorithm in the process of CTA 3D reconstruction and briefly summarize the rendering methods of CTA 3D reconstruction, finally, we will look into the future of CTA 3D reconstruction.
