    • A method for intracardially mapping a condition such as an electrical or mechanical property of a chamber of a heart uses a catheter having a distal tip and at least one condition sensor contained therein or proximate thereto. The at least one sensor is capable of sensing condition information in the chamber and provides the three-dimensional position of the catheter tip in a positional frame of reference. The method includes the steps of acquiring first and second images of the chamber. The images are acquired from different projections and contain topological information of the chamber. The chamber images are registered with the positional frame of reference. The catheter distal tip is advanced into the catheter and is navigated to acquisition points under the guidance of topological information contained in or derived from the images. Condition and position information are acquired at each of the acquisition points, the points being sufficient in number and spacing to permit the generation of a map of the condition in the chamber. The topological information used to guide the navigation of the catheter is preferably a three-dimensional reconstruction of the chamber derived from the topological information contained in the images.
    • 用于心脏内映射心脏室的电气或机械性质的状态的方法使用具有远端尖端的导管和至少一个状态传感器,其包含在其中或其附近。 所述至少一个传感器能够感测腔室中的状况信息,并且将导管尖端的三维位置提供在位置参考系中。 该方法包括获取腔室的第一和第二图像的步​​骤。 图像从不同的投影获得,并包含腔室的拓扑信息。 腔室图像以位置参考系登记。 导管远端尖端进入导管,并在包含或衍生自图像的拓扑信息的引导下导航到采集点。 在每个采集点获取条件和位置信息,这些点的数量和间距足以允许在室中产生条件的映射。 用于引导导管导航的拓扑信息优选地是从包含在图像中的拓扑信息导出的室的三维重建。

    • A method of reconstructing a map of a volume, including determining coordinates of a plurality of locations on a surface of the volume having a configuration, generating a grid of points defining a reconstruction surface in 3D space in proximity to the determined locations, for each of the points on the grid, defining a respective vector, dependent on a displacement between one or more of the points on the grid and one or more of the locations, and adjusting the reconstruction surface by moving substantially each of the points on the grid responsive to the respective vector, so that the reconstruction surface is deformed to resemble the configuration of the surface.
