[A virtual eversion method for blood vessels].

A virtual eversion method for human blood vessels is proposed in this paper, based on the virtual eversion methodology along electric field lines, and featured with a reference surface optimization using non-rigid registration. This method has the benefits of easy access with a larger view, and the ability to preserve the vessel's global anatomy and its local spatial relationship with other organs. A CT image dataset of arterial stenosis of lower extremities is tested to implement the virtual eversion experiment, and the results reveal the stenosis of artery clearly, which demonstrates the feasibility of this technique.
