In this paper we mostly research vessel segmentation, vessel centerline extraction and the threedimensionalrepresentation of vessels in the threedimensional reconstruction.
本文主要研究数字减影血管造影三维重建过程中的血管分割、中轴提取以及血管的三维表达问题。

The difficulty of unsteady threedimensional vector field data visualization stems from both data representation and management of large volume data.
非定常三维向量场可视化的难点不仅在于数据表现本身，还在于大体积数据的管理和组织。
