摘要： The present disclosure provides systems and methods for generating a patch surface model of a geometric structure. The system includes a computer-based model construction system configured to be coupled to a device that includes at least one sensor configured to acquire a set of original location data points corresponding to respective locations on a surface of the geometric structure, the computer-based model construction system further configured to generate a reference surface based on the acquired original location data points, subdivide the reference surface into a plurality of triangles, project at least some of the original location data points onto a respective nearest point on the subdivided reference surface, compute a function that morphs the projected location data points towards the original location data points to generate a patch surface model, and determine a boundary for the patch surface model.

摘要： Electrophysiological signals from a graphical representation of an electrophysiology map including a plurality of electrophysiology data points can be sorted by receiving user inputs specifying a number of virtual electrodes for a virtual catheter and defining a pathway of the virtual catheter. A corresponding number of virtual electrodes can be defined on the pathway of the virtual catheter, and one or more electrophysiology data points relevant to electrical activity at the virtual electrodes can be identified, allowing output of a graphical representation of electrophysiological signals corresponding to the identified electrophysiology data points. Relevant electrophysiololgy data points can be identified by applying one or more relevance criterion, such as a distance criterion, a bipole orientation criterion, a time criterion, and/or a morphology criterion.
