    摘要: An animated electrophysiology map is generated from a plurality of data points, each including measured electrophysiology information, location information, and timing information. The electrophysiology and location information can be used to generate the electrophysiology map, such as a local activation time, peak-to-peak voltage, or fractionation map. Animated timing markers can be superimposed upon the electrophysiology map using the electrophysiology, location, and timing information. For example a series of frames can be displayed sequentially, each including a static image of the electrophysiology map at a point in time and timing markers corresponding to the state or position of an activation wavefront at the point in time superimposed thereon. The visibility or opacity of the timing markers can be adjusted from frame to frame, dependent upon a distance between the timing marker and the activation wavefront, to give the illusion that the timing markers are moving along the electrophysiology map.

    摘要: Methods, apparatus, and systems for medical procedures are disclosed herein for receiving an input of a plurality of measured coordinates of a respective plurality of position transducers of a probe inside a body of a subject, receiving a measured voltage measurement output by the probe, determining a cost function based on a model of known mechanical properties of the probe compared to the measured coordinates with respect to shapes that can be assumed by the probe in the body and further based on an expected voltage value compared to the measured voltage measurement, selecting a shape based on the cost function, generating corrected coordinates of the points along the probe based on the shape and displaying a representation of the probe using the corrected coordinates.
