Abstract

Described embodiments include a system that includes a display and a processor. The processor is configured to modify an image slice by filling a portion, of the image slice, that corresponds to an anatomical cavity with a representation of a wall of the anatomical cavity, and to display the modified image slice on the display. Other embodiments are also described.

Claims

1. A system, comprising:

a display; and

a processor, configured;

to modify an image slice by filling a portion, of the image slice, that corresponds to an anatomical cavity with a representation of a wall of the anatomical cavity,

to identify the portion of the image slice that corresponds to the anatomical cavity, and

to display the modified image slice on the display.

3. The system according to claim 1, wherein the processor is configured to modify the portion of the image slice that corresponds to the anatomical cavity without modifying other portions of the image slice.

4. The system according to claim 1, wherein the processor is further configured to compute the representation by rendering the wall of the cavity.

5. The system according to claim 4, wherein the processor is configured to render the wall of the cavity in color.

6. The system according to claim 4, wherein the wall of the cavity is located behind a location at which the image slice was acquired.

7. The system according to claim 1, wherein the image slice is a computed tomography (CT) image slice.

8. The system according to claim 1, wherein the processor is further configured to overlay an icon that represents an intrabody tool on a portion of the modified image slice that corresponds to a location of the intrabody tool within the anatomical cavity.

9. The system according to claim 8, wherein the processor is further configured to overlay a marker on a portion of the representation of the wall that corresponds to a location at which the intrabody tool would meet the wall, were the intrabody tool to continue moving toward the wall in a direction in which the intrabody tool is pointing.

10. The system according to claim 9, wherein the processor is further configured to identify the location at which the intrabody tool would meet the wall, by projecting a virtual ray from a distal tip of the intrabody tool.

2. (canceled)

11. A method, comprising:

using a processor, modifying an image slice by filling a portion, of the image slice, that corresponds to an anatomical cavity with a representation of a wall of the anatomical cavity;

using the processor, identifying the portion of the image slice that corresponds to the anatomical cavity; and

displaying the modified image slice.

13. The method according to claim 11, wherein modifying the portion of the image slice that corresponds to the anatomical cavity comprises modifying the portion of the image slice that corresponds to the anatomical cavity without modifying other portions of the image slice.

14. The method according to claim 11, further comprising computing the representation by rendering the wall of the cavity.

15. The method according to claim 14, wherein rendering the wall of the cavity comprises rendering the wall of the cavity in color.

16. The method according to claim 14, wherein the wall of the cavity is located behind a location at which the image slice was acquired.

17. The method according to claim 11, wherein the image slice is a computed tomography (CT) image slice.

18. The method according to claim 11, further comprising overlaying an icon that represents an intrabody tool on a portion of the modified image slice that corresponds to a location of the intrabody tool within the anatomical cavity.

19. The method according to claim 18, further comprising overlaying a marker on a portion of the representation of the wall that corresponds to a location at which the intrabody tool would meet the wall, were the intrabody tool to continue moving toward the wall in a direction in which the intrabody tool is pointing.

20. The method according to claim 19, further comprising identifying the location at which the intrabody tool would meet the wall, by projecting a virtual ray from a distal tip of the intrabody tool.

12. (canceled)
