Abstract
Claims
1. It is a system, A memory configured to store multiple electroanatomically mapped mapping locations acquired within the cardiac cavity, and a point cloud of locations within the cavity marked for ablation, It is a processor, Receiving or generating a volume map of at least a portion of the cavity, including the plurality of mapping locations, Updating the volume map by removing a portion of the mapping location so that the location marked for ablation lies on the surface of the volume map, Using the updated volume map, generate a map of at least a portion of the cavity, including the locations marked for the ablation. A processor configured to display the aforementioned map to the user, The processor is configured to project the positions marked for ablation onto the respective positions on the surface of the volume map, and to remove a portion of the volume map that includes a surface connecting the projected positions which are the ablation-marked positions. The processor is configured to remove a surface that connects the marked positions for ablation to the projected marked positions for ablation by removing a surface defined as the surface between a first curve generated by interconnecting the marked positions for ablation and a second curve generated by interconnecting the projected marked positions for ablation. system.
2. The system according to claim 1, wherein the processor is configured to identify one or more locations among the locations marked for ablation that fall within the volume map, and to remove the portion such that the identified locations marked for ablation fall on the surface of the volume map.
3. The system according to claim 1, wherein the location marked for ablation is a location on the cardiac wall tissue that is marked for ablation.
4. The system according to claim 3, wherein the processor is configured to generate the map by generating an electroanatomical (EA) map of at least a portion of the heart wall tissue.
5. The system according to claim 1, wherein the processor is configured to remove the portion of the volume map by defining the respective distance to penetrate the surface between each marked position for ablation and each projected position on the surface, and defining the portion to be removed based on the distance.
6. The system according to claim 5, wherein the processor is configured to define the portion of the volume map to be removed by defining a sphere having a diameter corresponding to the distance.
7. The system according to claim 1, wherein the processor is configured to display the map to the user by presenting one or more icons at the locations marked for the ablation.
8. A program, and when the program is loaded into the processor, the processor, Receiving or generating a volume map including multiple electroanatomically mapped mapping locations of at least a portion of the cardiac cavity, and a point cloud of locations within the cavity marked for ablation, Updating the volume map by removing a portion of the mapping locations so that the locations marked for ablation fit on the surface of the volume map, Using the updated volume map, generate a map of at least a portion of the cavity, including the locations marked for the ablation. The aforementioned map is displayed to the user, and the following is performed: Removing the portion of the mapping locations includes projecting the locations marked for ablation onto the respective locations on the surface of the volume map, and removing the portion of the volume map that includes a surface connecting the locations marked for ablation to the projected locations marked for ablation. Removing the surface connecting the positions marked for ablation to the projected positions marked for ablation includes removing the surface defined as the surface between a first curve generated by interconnecting the positions marked for ablation and a second curve generated by interconnecting the projected positions marked for ablation. program.
9. The program according to claim 8, wherein removing the portion of the mapping locations includes identifying one or more locations among the locations marked for ablation that fall within the volume map, and removing the portion such that the identified locations marked for ablation fall on the surface of the volume map.
10. The program according to claim 8, wherein the location marked for ablation is a location on the cardiac wall tissue that is marked for ablation.
11. The program according to claim 10, wherein generating the map includes generating an electroanatomical (EA) map of at least a portion of the cardiac wall tissue.
12. The program according to claim 8, wherein removing the portion of the volume map includes defining the respective distance to penetrate the surface between each marked position for ablation and each projected position on the surface, and defining the portion to be removed based on the distance.
13. The program according to claim 12, wherein defining the portion of the volume to be removed includes defining a sphere having a diameter corresponding to the distance.
14. The program according to claim 8, wherein displaying the map to the user includes presenting one or more icons at the locations marked for the ablation.
