A computing system is provided. The computing system includes a memory storing processor executable code. The computing system includes processors executing the code. The code causes the computing system to generate a graphical user interface that includes topological maps constructed from a three-dimensional anatomical model of a portion of an anatomical feature. The topological maps include an interior map view of the portion of the anatomical feature from a perspective of a device inserted into a patient. The code causes the computing system to generate a device icon on each of the topological maps. The device icon presents a real time position of an ablating surface of the device in relation to each map view of the topological maps.

Cardiac vein ablation visualization system and catheter

Disclosed are systems and methods for visualization of pulsed field ablation tags. In some implementations, a system includes a device, comprising a processor in communication with one or more sensors and a catheter comprising a plurality of electrodes. In some implementations, the processor is configured to: receive, via the one or more sensors, a position of each of the plurality of electrodes within a three-dimensional environment during a first ablation session; calculate, for the first ablation session, a first implicit function representing an energy field of the first ablation session from the received positions of each of the plurality of electrodes; and present, via a display, a first volumetric representation of the calculated first implicit function.

Using signed distance functions to visualize pulsed field ablation (PFA) tags

A method includes assigning, to first voxels in a model of tissue of a chamber of a heart, respective first values of a parameter at respective locations on the tissue, the first voxels representing the locations, respectively. Some of the locations are on an endocardial surface of the tissue, and others of the locations are on an epicardial surface of the tissue. The method further includes assigning respective second values to second voxels in the model, a subset of which represent a portion of the tissue between the endocardial surface and the epicardial surface, by interpolating the first values. Other embodiments are also described.

Volumetric LAT map

Display screen or portion thereof with icon

Methods, apparatus, and systems for medical procedures include receiving a first ultrasound slice from an ultrasound transducer, the first ultrasound slice corresponding to a first ultrasound position. A second ultrasound slice is received from the ultrasound transducer, the second ultrasound slice corresponding to a second ultrasound position. The first ultrasound slice and the second ultrasound slice are stored in memory. A first catheter position of a catheter is received. The first catheter position is determined to correspond to the first ultrasound position and the first ultrasound slice is provided based on the determination. The determination that the first catheter position corresponds to the first ultrasound position may be made based on locations, orientations, or may be based on the number of voxels that overlap between the first catheter position and ultrasound positions.

Historical ultrasound data for display of live location data

A system and method for detecting a mapping annotation for an electrophysiological (EP) mapping system. The system includes a processor comprising a machine learning algorithm configured to receive a first heartbeat at an identified cardiac spatial location including a first set of attributes information corresponding to the first heartbeat; receive a second heartbeat at the identified cardiac spatial location including a second set of attributes information corresponding to the second heartbeat; compare the first set of attributes information with the second set of attributes information; and determine which of the first heartbeat and the second heartbeat has optimal characteristics based on the compared attribute information.

System and method to detect stable arrhythmia heartbeat and to calculate and detect cardiac mapping annotations

A method for producing an image of a body tissue surface. The method includes transforming a source 3-D model of the body tissue surface into a flattened model comprising details of the body tissue surface represented visually on an unwrapped and flattened surface, wherein the flattened model represents transformed positions of the source 3-D model of the body tissue surface defined between a first edge and a second edge. The first edge is formed about a lumen defined by the body tissue surface, and the body tissue surface projects about the lumen to the second edge. The method further includes producing an image from the flattened model.

Flattened organ display

A system includes a processor and a display. The processor is configured to: (i) receive a first dataset corresponding to a first property of an organ of a patient, and a second dataset corresponding to a second property of the organ, (ii) assign a first visual attribute to the first property and a second visual attribute to the second property, and (iii) produce a map of the organ including an overlay of the first and second visual attributes. The display is configured to display the map.

Visualizing multiple parameters overlaid on an anatomical map

A method includes, receiving, on a surface of an anatomical map of a patient organ having a first presentation, a selection of a first selected region, which is intended to have a second presentation, different from the first presentation. A perimeter of the first selected region, and at least an unselected area positioned within the first selected region, are identified. A second selected region is produced, the second selected region includes the first selected region and the unselected area. The anatomical map, having the second presentation applied to the second selected region, is displayed.

Regional resolution in fast anatomical mapping

A method includes calculating a first medial-axis tree graph of a volume of an organ of a patient in a first computerized anatomical map of the volume, acquired at a first time. A second medial-axis tree graph is calculated, of a volume of the organ of the patient in a second computerized anatomical map of the volume, acquired at a second time that is different from the first time. A deviation is detected and estimated, between the first and second tree-graphs. Using the estimated deviation, the first and second medial-axis tree graphs are registered with one another. Using the registered first and second tree graphs, the first and second computerized anatomical maps are combined.

Automatic registration of an anatomical map to a previous anatomical map

Methods, devices, and systems for acquiring the volume of a catheter are disclosed. The system may comprise a catheter and a processor. The processor may be configured to receive a voxel grid comprising a plurality of voxels and a plurality three-dimensional coordinates of a location of a catheter. The processor may render the catheter on a display using the three-dimensional coordinates, wherein the catheter rendering comprises a plurality of shaded pixels. The processor may identify coordinates of one or more voxels of the voxel grid which overlap with at least one shaded pixel and mark the voxels of the voxel grid which overlap with at least one shaded pixel. As such, a voxel trail may be created wherever a catheter moves. The voxel trail may be used to define an internal volume within which the catheter is positioned, such as a chamber of a heart, blood vessel, or valve.

Catheter representation via voxels within organ

A method includes receiving or generating a volume map of at least a portion of a cavity of an organ of a body including a plurality of mapped locations, and a point cloud of locations in the cavity marked for treatment. The volume map is updated by removing a portion of the mapped locations, so that the locations marked for treatment fall on a surface of the volume map. Using the updated volume map, a map of at least a portion of the cavity is generated, the map including the locations marked for treatment. The map is displayed to user.

A system includes a display and a processor. The processor is configured to: (i) receive a dataset including multiple data points, each data point corresponding to one or more properties of an organ of a patient, (ii) produce, based on a clustering criterion, at least a cluster including two or more of the data points, and (iii) produce and present on the display, a map of the organ and at least an object indicative of the cluster. In response to selection of the object by a user, the processor is configured to produce and present on the display, a two-dimensional (2D) table including the one or more properties of each of the clustered data points.
