More Information
Summary:The invention is entitled as mesh fitting algorithm. The invention provides cardiac catheterization. Cardiac catheterization is carried out by inserting a multi-electrode probe into a heart, constructing a position map of the electrodes, and simulating a 3-dimensional surface of the heart. The method is further carried out by placing the position map in registration with an acquired image of the heart, constructing, based on the position map, a mesh that models the 3-dimensional surface of the heart, and adjusting positions of vertices of the mesh relative to mapped points in the position mapto improve a registration of the mesh with the acquired image. 本发明题为"网格拟合算法"。本发明提供了心导管插入术，该心导管插入术通过以下方式来执行：将多电极探头插入到心脏中，构建电极的位置标测图，以及模拟心脏的三维表面。该方法通过以下方式来进步执行：将位置标测图放置成与心脏的采集的图像配准，基于位置标测图来构建对心脏的三维表面建模的网格，以及相对于位置标测图中的标测点来调节网格的顶点的位置以改善网格与采集的图像的配准。
