Abstract

A method for mapping a body organ, including receiving a three-dimensional (3D) map of the body organ having a multiplicity of map elements, each map element having a graphic attribute indicative of a local property of the body organ. The method further includes delineating a selected region of the map, so that the map is divided into the selected region and a non-selected region. The 3D map is displayed while the graphic attribute of the map elements specifically within the selected region are altered.

First claim

We claim:

1 . A method for mapping a body organ, comprising:
receiving a three-dimensional (3D) map of the body organ comprising a multiplicity of map elements, each map element having a graphic attribute indicative of a local property of the body organ; delineating a selected region of the map, so that the map is divided into the selected region and a non-selected region; and displaying the 3D map while altering the graphic attribute of the map elements specifically within the selected region.

2 . The method according to claim 1 , wherein displaying the 3D map comprises not altering the graphic attribute of the geometric map-elements within the non-selected region.

3 . The method according to claim 1 , wherein delineating the selected region comprises generating a closed perimeter on the 3D map separating the selected region from the non-selected region.

4 . The method according to claim 3 , wherein the selected region is within the perimeter.

5 . The method according to claim 3 , wherein the selected region is external to the perimeter.

6 . The method according to claim 1 , wherein delineating the selected region comprises initially generating a closed perimeter on the 3D map separating the selected region from the non-selected region, and subsequently changing the closed perimeter so as to alter the selected region and the non-selected region.

7 . The method according to claim 1 , wherein the body organ comprises a heart, and wherein the local property comprises at least one of a temperature, an electropotential, a resistivity, a contractility, and a local activation time (LAT) of the heart.

8 . The method according to claim 1 , and comprising:
incorporating into the 3D map one or more geometric figures, each geometric figure being representative of at least a portion of an entity associated with a local region of the body organ and having a further graphic attribute, and displaying the 3D map while altering the further graphic attribute of the one or more geometric figures specifically within the selected region.

9 . The method according to claim 1 , wherein the graphic attribute comprises at least one of a color value, a visibility, and a transparency.

10 . A method for mapping a body organ, comprising:
receiving a three-dimensional (3D) map of the body organ comprising one or more geometric figures, each geometric figure having a graphic attribute and being representative of at least a portion of an entity associated with a local region of the body organ; delineating a selected region of the map, so that the map is divided into the selected region and a non-selected region; and displaying the 3D map while altering the graphic attribute of the each geometric figure specifically within the selected region.

11 . The method according to claim 10 , wherein the geometric figures comprise at least one of a distal tip icon representative of a location and orientation of a catheter distal tip and an ablation icon representative of an ablation performed on a region of the body organ.

12 . Apparatus for mapping a body organ, comprising:
a processor which is configured to receive a three-dimensional (3D) map of the body organ comprising a multiplicity of map elements, each map element having a graphic attribute indicative of a local property of the body organ, and to delineate a selected region of the map, so that the map is divided into the selected region and a non-selected region; and a screen which is configured to display the 3D map while altering the graphic attribute of the map elements specifically within the selected region.

13 . The apparatus according to claim 12 , wherein displaying the 3D map comprises not altering the graphic attribute of the geometric map-elements within the non-selected region.

14 . The apparatus according to claim 12 , wherein delineating the selected region comprises generating a closed perimeter on the 3D map separating the selected region from the non-selected region.

15 . The apparatus according to claim 14 , wherein the selected region is within the perimeter.

16 . The apparatus according to claim 14 , wherein the selected region is external to the perimeter.

17 . The apparatus according to claim 12 , wherein delineating the selected region comprises initially generating a closed perimeter on the 3D map separating the selected region from the non-selected region, and subsequently changing the closed perimeter so as to alter the selected region and the non-selected region.

18 . The apparatus according to claim 12 , wherein the body organ comprises a heart, and wherein the local property comprises at least one of a temperature, an electropotential, a resistivity, a contractility, and a local activation time (LAT) of the heart.

19 . The apparatus according to claim 12 , wherein the processor is configured to incorporate into the 3D map one or more geometric figures, each geometric figure being representative of at least a portion of an entity associated with a local region of the body organ and having a further graphic attribute, and wherein the screen is configured to display the 3D map while altering the further graphic attribute of the one or more geometric figures specifically within the selected region.

20 . The apparatus according to claim 12 , wherein the graphic attribute comprises at least one of a color value, a visibility, and a transparency.

21 . Apparatus for mapping a body organ, comprising:
a processor which is configured to receive a three-dimensional (3D) map of the body organ comprising one or more geometric figures, each geometric figure having a graphic attribute and being representative of at least a portion of an entity associated with a local region of the body organ, and to delineate a selected region of the map, so that the map is divided into the selected region and a non-selected region; and a screen which is configured to display the 3D map while altering the graphic attribute of the each geometric figure specifically within the selected region.

22 . The apparatus according to claim 21 , wherein the geometric figures comprise at least one of a distal tip icon representative of a location and orientation of a catheter distal tip and an ablation icon representative of an ablation performed on a region of the body organ.
