Verfahren und Vorrichtung zur visuellen Unterstützung einer elektrophysiologischen Katheteranwendung

摘要

A method for visually supporting an electrophysiological catheter application is provided. An electroanatomical 3D mapping data of a region of interest in the heart is visualized. A 3D image data of the region of interest is captured before the catheter application. A 3D surface profile of objects in the region of interest is extracted from the 3D image data by segmentation. The electroanatomical 3D mapping data and 3D image data forming at least the 3D surface profile is assigned by registration and visualized superimposed on one another. Characteristic parameters are measured for catheter guidance during the catheter application. The characteristic parameters are compared with at least one predefined threshold value and regulation data for catheter guidance is generated as a function of the comparison result. The regulation data is integrally displayed and represented in the superimposed visualization.
