Blood vascular reconstruction plays an important role in vessel disease diagnosis and prognosis, treatment planning and surgery. Based on adjacent vector projection, a simple and robust explicit algorithm is presented for vascular reconstruction. It generates the base mesh and utilizes the Loop algorithm for perceptual refinement by mesh subdivision. In the end, the reconstructed vascular tree is rendered for volumetric visualization and localization of vascular malformations. Experimental results on the Aneurisk database have validated the capacity of the proposed algorithm in generating smooth surface and natural transition of high tortuosity in real time, while on clinical cases has verified its accuracy on pinning vascular stenosis.
