Fast anatomical mapping (FAM) reconstruction using surface update restrictions
A method includes presenting, on a display, an electroanatomical (EA) map of a surface of a cavity of an organ. Input is received from a user, and, in response to the user input, a region of the EA map is locked to subsequent updates.
1. A method for fast anatomical mapping reconstruction, the method comprising:
presenting, on a display, an electroanatomical (EA) map of a surface of a cavity of an organ;
receiving input from a user; and
in response to the user input, locking a region of the EA map to subsequent updates, wherein locking the region comprises preventing subsequent updates in prespecified proximity of an anatomical feature in the EA map and wherein the EP map comprise an EA map of the left atrium, and wherein the anatomical feature is a pulmonary vein.
2. The method according to claim 1 , wherein locking the region comprises preventing subsequent manual editing of the EA map.
3. The method according to claim 1 , wherein locking the region comprises ignoring subsequently acquired data points belonging to the region.
4. The method according to claim 1 , wherein locking the region is performed in response to identifying that data points in the region were obtained by a probe while applying excessive force to the surface.
5. The method according to claim 1 , and comprising manually editing unlocked regions of the EA map to remove irrelevant data points therein.
6. The method according to claim 1 , and comprising:
unlocking the locked region;
manually editing the unlocked region of the EA map to remove irrelevant data points therein; and
re-locking the manually edited region.
7. A system for fast anatomical mapping reconstruction, the system comprising:
a display, which is configured to present an electroanatomical (EA) map of a surface of a cavity of an organ; and
a processor, which is configured to receive input from a user, and, in response to the user input, to lock a region of the EA map to subsequent updates, wherein the processor is configured to lock the region by preventing subsequent updates in prespecified proximity of an anatomical feature in the EA map and wherein the EP map comprise an EA map of the left atrium, and wherein the anatomical feature is a pulmonary vein.
8. The system according to claim 7 , wherein the processor is configured to lock the region by preventing subsequent manual editing of the EA map.
9. The system according to claim 7 , wherein the processor is configured to lock the region by ignoring subsequently acquired data points belonging to the region.
10. The system according to claim 7 , wherein the processor is configured to lock the region in response to identifying that data points in the region were obtained by a probe while applying excessive force to the surface.
11. The system according to claim 7 , wherein the processor is configured to receive further user input that manually edits unlocked regions of the EA map to remove irrelevant data points therein.
12. The system according to claim 7 , wherein the processor is configured to:
unlock the locked region;
receive further user input that manually edits the unlocked region of the EA map to remove irrelevant data points therein; and
re-lock the manually edited region.
