摘要： A method includes presenting to a user a three-dimensional (3D) map of at least part of an organ of a patient, the 3D map generated by a position-tracking system. An artificial object, which is non-trackable by the position-tracking system, is identified in a medical image of at least part of the organ. A graphical representation of the non-trackable artificial object is presented to the user on the 3D map.

摘要： A method, including acquiring initial signals from selected positions in a heart, computing respective initial local values of a signal propagation metric at the selected positions, and interpolating the initial local values between the selected positions to compute initial interpolated values of the signal propagation metric at intermediate positions, between the selected positions. The method further includes acquiring subsequent signals from the positions, computing respective subsequent local values of the signal propagation metric at the selected positions, and spatially interpolating the subsequent local values of the signal propagation metric between the selected positions to compute subsequent interpolated values of the signal propagation metric at the intermediate positions. A map of the signal propagation metric is displayed, and when the subsequent interpolated values exceed a bound defined with respect to the initial interpolated values, an indication is provided on the map that the bound has been exceeded.

摘要： A method includes registering a fluoroscopic imaging system and a position tracking system to a common frame of reference. A region of interest is marked in a patient body by the position tracking system. Using the common frame of reference, a field of view of the fluoroscopic imaging system is set such that the region of interest appears in the field of view.

摘要： A method includes receiving, via a plurality of electrodes in a heart, a collection of acquisitions, each including a set of electrophysiological (EP) signals measured by the electrodes. A respective direction of arrival (DOA) and a respective distance relative to the electrodes from which the set of EP signals originated are estimated for each acquisition. The acquisitions are aggregated, to form a statistical distribution of the acquisitions as a function of estimated DOA and distance. Using a statistical test, it is checked whether the statistical distribution is consistent, in accordance with a predefined consistency criterion. If the statistical distribution is found consistent, an estimated location in the heart of a focal source of an arrhythmogenic activity that generated the received EP signals is derived from the statistical distribution. The estimated location of the focal source is overlaid on an anatomical map of at least a portion of the heart.

摘要： A method includes receiving, via a plurality of electrodes in a heart, a collection of acquisitions, wherein each acquisition comprises a set of electrophysiological (EP) signals measured by the electrodes. A respective direction of arrival (DOA) and a respective distance relative to the electrodes from which the set of EP signals originated are estimated for at least some of the acquisitions. Based on the estimated DOA and distance, a timing error is estimated in at least an EP signal among the EP signals. A timing of the EP signal is adjusted to fit the estimated DOA and distance and correct the error. An EP map of at least a portion of the heart is generated using the set of EP signals, including the adjusted EP signal.

摘要： Catheterization of the heart is carried out by inserting a probe having electrodes into a heart of a living subject, recording a bipolar electrogram and a unipolar electrogram from one of the electrodes at a location in the heart, and defining a window of interest wherein a rate of change in a potential of the bipolar electrogram exceeds a predetermined value. An annotation is established in the unipolar electrogram, wherein the annotation denotes a maximum rate of change in a potential of the unipolar electrogram within the window of interest. A quality value is assigned to the annotation, and a 3-dimensional map is generated of a portion of the heart that includes the annotation and the quality value thereof.
