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: An electroanatomical mapping system tracks and visualizes an item of interest, such as a medical device or anatomical structure, as the item moves within a non-ionizing localization field. The system localizes the item within the localization field and determines the initial position of the item with respect to an imaging device (e.g., an intracardiac echocardiography catheter) field of view. The system displays a region of the field of view containing the initial position of the item if it is within the field of view. If not, the system can output a notification. As the item moves, the system can update the displayed region so that it remains focused on the item, and can output a notification if the item exits the field of view. The displayed region(s) can include one or more two-dimensional image slices, optionally output as a three-dimensional volumetric image.
