Abstract

A method for data display includes acquiring a three-dimensional (3D) map of a lumen inside a body of a subject, transforming the 3D map of the lumen into a two-dimensional (2D) image by projecting the 3D map onto an annulus, and presenting the 2D image on a display screen.

Claims

1. A method for controlling display of data during a medical procedure, the method comprising:

acquiring location signals indicating a location of a probe in a three-dimensional (3D) space, including a lumen, inside a body of a subject, the lumen extending lengthwise between a first circumferential edge and a second circumferential edge;

presenting a 3D map of the 3D space including the lumen and the location of the probe at a portion of the lumen;

transforming the 3D map of the lumen into a two-dimensional (2D) image by projecting the 3D map of the lumen onto a 2D annulus, the annulus comprising an inner circumferential edge corresponding to the first circumferential edge of the lumen in the 3D space and an outer circumferential edge corresponding to the second circumferential edge of the lumen in the 3D space;

presenting the 2D image of the annulus on a display screen including the location of the probe at a portion of the annulus between the inner circumferential edge and the outer circumferential edge;

presenting the location of one or more ablation lesions, presented on the 3D map, on the 2D image of the annulus;

calculating an ablation path for the one or more ablation lesions on the lumen; and

displaying the ablation path between the first circumferential edge and the second circumferential edge on the lumen on the 3D map and between the inner circumferential edge and the outer circumferential edge on the 2D image of the annulus.

2. The method according to claim 1, wherein presenting the 2D image comprises presenting a stationary 2D image of the annulus.

3. The method according to claim 2, comprising presenting the 3D map and the stationary 2D image simultaneously on adjacent parts of the display screen.

4. The method according to claim 3, comprising maintaining the 2D image of the annulus as a stationary image while manipulating the 3D the lumen in one or more directions on the 3D map.

5. The method according to claim 1, wherein the lumen is a pulmonary vein of a heart.

6. The method according to claim 5, further comprising determining a completion of an ablation procedure in response to presenting an image of a contiguous closed lesion on the 2D image of the annulus.

7. The method according to claim 1, further comprising:

calculating a starting point for a further ablation lesion based on at least one of a calculated location of a previous ablation lesion and an extent of the further ablation lesion; and

displaying the starting point as a mark on the lumen on the 3D map and on the 2D image of the annulus.

8. A processing and display apparatus for use in a medical procedure, comprising:

a display screen; and

a processor which is configured to;

acquire location signals indicating a location of a probe in a three-dimensional (3D) space, including a lumen, inside a body of a subject, the lumen extending lengthwise between a first circumferential edge and a second circumferential edge;

present a 3D map of the 3D space, including the lumen and the location of the probe at a portion of the lumen, on the display screen;

transform the 3D map of the lumen into a 2D image by projecting the 3D map of the lumen onto a 2D annulus, the annulus comprising an inner circumferential edge corresponding to the first circumferential edge of the lumen in the 3D space and an outer circumferential edge corresponding to the second circumferential edge of the lumen in the 3D space;

present the 2D image of the annulus on the display screen including the location of the probe at a portion of the annulus between the inner circumferential edge and the outer circumferential edge;

calculate an ablation path for the one or more ablation lesions on the lumen, and

display the ablation path between the first circumferential edge and the second circumferential edge on the lumen on the 3D map and between the inner circumferential edge and the outer circumferential edge on the 2D image of the annulus.

9. The apparatus according to claim 8, wherein the 2D image of the annulus is stationary.

10. The apparatus according to claim 8, wherein the processor is configured to present the 3D map and the stationary 2D image simultaneously on adjacent parts of the display screen.

11. The apparatus according to claim 10, wherein the processor is configured to maintain the 2D image of the annulus as a stationary image while manipulating the 3D the lumen in one or more directions on the 3D map.

12. The apparatus according to claim 8, wherein the lumen is a pulmonary vein of a heart.

13. The apparatus according to claim 12, wherein the processor is configured to determine a completion of an ablation procedure in response to presenting an image of a continuous closed lesion on the 2D image of the annulus.

14. The apparatus according to claim 8, wherein the processor is configured to:

calculate a starting point for a further ablation lesion based on at least one of a calculated location of a previous ablation lesion and an extent of the further ablation lesion, and

display the starting point as a mark on the lumen on the 3D map and on the 2D image of the annulus.

15. A non-transitory computer readable medium having instructions for causing a computer to perform a method of controlling display of data during a medical procedure, the method comprising:

acquiring location signals indicating a location of a probe in a three-dimensional (3D) space, including a lumen, inside a body of a subject, the lumen extending lengthwise between a first circumferential edge and a second circumferential edge;

presenting a 3D map of the 3D space including the lumen and the location of the probe at a portion of the lumen;

transforming the 3D map of the lumen into a two-dimensional (2D) image by projecting the 3D map of the lumen onto a 2D annulus, the annulus comprising an inner circumferential edge corresponding to the first circumferential edge of the lumen in the 3D space and an outer circumferential edge corresponding to the second circumferential edge of the lumen in the 3D space; and

presenting the 2D image of the annulus on a display screen including the location of the probe at a portion of the annulus between the inner circumferential edge and the outer circumferential edge;

presenting the location of one or more ablation lesions, presented on the 3D map, on the 2D image of the annulus;

calculating an ablation path for the one or more ablation lesions on the lumen; and

displaying the ablation path between the first circumferential edge and the second circumferential edge on the lumen on the 3D map and between the inner circumferential edge and the outer circumferential edge on the 2D image of the annulus.
