We have developed a novel model-to-image registration technique which aligns a 3-dimensional model of vasculature with two semiorthogonal fluoroscopic projections. Our vascular registration method is used to intra-operatively initialize the alignment of a catheter and a preoperative vascular model in the context of image-guided TIPS (Transjugular, Intrahepatic, Portosystemic Shunt formation) surgery. Registration optimization is driven by the intensity information from the projection pairs at sample points along the centerlines of the model. Our algorithm shows speed, accuracy and consistency given clinical data.
我们开发了一种新颖的模型到图像配准技术，该技术可将三维血管模型与两个半正交荧光透视投影对齐。我们的血管配准方法用于在图像引导的经颈静脉肝内门体分流术（TIPS）手术中，在术中初始化导管与术前血管模型的对齐。配准优化由沿模型中心线的采样点处投影对的强度信息驱动。根据临床数据，我们的算法显示出速度、准确性和一致性。
