血管的虚拟外翻方法

A Virtual Eversion Method for Blood Vessels

设计了一种血管虚拟外翻方法。该方法以沿电场线虚拟外翻理论为基础,以非刚性配准方法优化外翻基准面为特点,具有视野开阔、观察便捷、能保持与周围器官解剖对照关系等优点。用真实病人的下肢动脉血管图像进行实验,所得外翻图像能够完整揭示动脉狭窄,证明了该方法的有效性。

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. ACT 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.
