Abstract: A three-dimensional geometric model of a heart can be generated from a plurality of two-dimensional image slices of the heart collected using an intracardiac echocardiography (“ICE”) catheter. Each image slice can be associated with localization information for the ICE catheter. The image slices can be output in a plurality of voxels according to their associated localization information, thereby creating a three-dimensional geometric model of the heart. Data sufficiency of the three-dimensional model can also be graphically represented. For example, data sufficiency can be represented using voxel opacity, a one-dimensional illustration, a two-dimensional illustration, and/or a data collection cue.

Abstract: A system includes a display and a processor. The processor is configured to compute multiple forecasted local activation times (LATs) at different respective locations on cardiac tissue of a subject, by simulating a propagation of a physiological activation potential along the cardiac tissue with a particular portion of the cardiac tissue, which is currently conductive, being non-conductive. The processor is further configured to generate, based on the forecasted LATs, a forecasted electroanatomical map representing a forecasted state of the cardiac tissue following an ablation of the particular portion of the cardiac tissue, and to display the forecasted electroanatomical map on the display. Other embodiments are also described.

Abstract: Methods, systems, and apparatuses for visualizing the motion box of an electromagnetic sensor tracking system on a display that can be viewed by the physician are disclosed. Electromagnetic sensor tracking systems are able to determine the position and orientation (P&O) of the sensors being tracked only when the sensors are within the motion box, or the spatial region located in proximity to the electromagnetic field generators of the system. During usage of the electromagnetic sensor tracking system, the sensor can go out of this spatial region and, when this occurs, navigating it back into the motion box can be difficult. The methods, systems, and apparatuses described herein provide for the representation of sensors, the motion box, and a representation of a thorax on a display so that the clinician can view the position and orientation of the sensors with respect to the motion box.
