Abstract

A system employs an interventional tool (30), ultrasound imaging system and a multi-planar reformatting module (40). The interventional tool (30) has one or more image tracking points (31). The ultrasound imaging system includes an ultrasound probe (20) operable for generating an ultrasound volume image (22) of a portion or an entirety of the interventional tool (30) within an anatomical region. The multi-planar reformatting imaging module (40) generates two or more multi- planar reformatting images (41) of the interventional tool (30) within the anatomical region. A generation of the two multi-planar reformatting images (41) includes an identification of each image tracking point (31) within the ultrasound volume image (22), and a utilization of each identified image tracking point (31) as an origin of the multi-planar reformatting images (41).

First claim

The invention claimed is:

1. A system, comprising:
an interventional tool having at least one image tracking point;
an ultrasound imaging system including an ultrasound probe operable to generate an ultrasound volume image of at least a portion of the interventional tool within an anatomical region; and
a multi-planar reformatting imaging module operable to generate at least two multi-planar reformatting images of the ultrasound volume image of the at least a portion of the interventional tool within the anatomical region, wherein a generation of the at least two multi-planar reformatting images includes:
an identification of each image tracking point within the ultrasound volume image; and
a utilization of each identified image tracking point as an origin of at least one of the least two multi-planar reformatting images.

2. The system of claim 1 , wherein the interventional tool is a catheter.

3. The system of claim 1 , wherein the imaging tracking point is located within a tip section of the interventional tool.

4. The system of claim 1 , wherein the at least two multi-planar reformatting images are orthogonal.

5. The system of claim 1 , wherein each multi-planar reformatting image has a fixed orientation within the ultrasound volume image.

6. The system of claim 1 , wherein the multi-planar reformatting imaging module is further operable to dynamically update the least two multi-planar reformatting images as the interventional tool is navigated within the anatomical region.

7. The system of claim 1 , wherein the multi-planar reformatting imaging module is further operable to dynamically update the least two multi-planar reformatting images as the ultrasound probe is moved relative to the anatomical region.

8. The system of claim 1 , further comprising:
an X-ray imaging system operable to generate at least two X-ray images of the at least a portion of the interventional tool within the anatomical region, wherein the identification of each imaging tracking point within the ultrasound volume image includes:
an identification of each imaging tracking point within the at least two X-ray images; and
a conversion of each identified imaging tracking point within the at least two X-ray images to the ultrasound volume image.

9. The system of claim 1 , further comprising:
a global tracking system including at least one tool sensor integrated with the interventional tool, wherein each tool sensor defines one of the at least one imaging tracking point.

10. The system of claim 9 , wherein each tool sensor is an electromagnetic sensor.

11. The system of claim 9 ,
wherein the global tracking system further includes at least one probe sensor integrated with the ultrasound probe; and
wherein the identification of each imaging tracking point within the ultrasound volume image includes a co-registration of each tool sensor and each probe sensor to a global tracking coordinate system.

12. The system of claim 9 , wherein the generation of the at least two multi-planar reformatting images includes:
generating the at least two multi-planar reformatting images normal to the interventional tool relative to the tool sensors.

13. The system of claim 12 , wherein the multi-planar reformatting imaging module is further operable to stack the at least two multi-planar reformatting images to form a warped ultrasound volume image relative to an axial alignment of the at least a portion of the interventional tool within the ultrasound volume image.

14. The system of claim 13 , wherein the multi-planar reformatting imaging module is further operable to slice the warped ultrasound volume image into at least one additional multi-planar reformatting image to visualize the at least portion of the interventional tool and surrounding portions of the anatomical region.

15. The system of claim 13 , further comprising:
an image modality operable to generate a scan image of the anatomical region,
wherein the multi-planar reformatting imaging module is further operable for fusing the warped ultrasound volume image and the scan image.

16. A method, comprising:
navigating an interventional tool within an anatomical region, the interventional tool having at least one image tracking point;
an ultrasound probe generating an ultrasound volume image of at least a portion of the interventional tool within the anatomical region; and
a multi-planar reformatting imaging module generating at least two multi-planar reformatting images of the ultrasound volume image of the at least a portion of the interventional tool within the anatomical region, wherein the generation of the at least two multi-planar reformatting images includes:
an identification of each image tracking point within the ultrasound volume image; and
a utilization of each identified image tracking point as an origin of at least one of the least two multi-planar reformatting images.

17. The method of claim 16 , further comprising:
an X-ray imaging system generating at least two X-ray images of the at least a portion of the interventional tool within the anatomical region, wherein the identification of each imaging tracking point within the ultrasound volume image includes:
an identification of each imaging tracking point within the at least two X-ray images; and
a conversion of each identified imaging tracking point within the at least two X-ray images to the ultrasound volume image.

18. The method of claim 16 , further comprising:
a global tracking system including at least one tool sensor integrated with the interventional tool and at least one probe sensor integrated with the ultrasound probe,
wherein each tool sensor defines one of the at least one imaging tracking point, and
wherein the identification of each imaging tracking point within the ultrasound volume image includes a co-registration of the at least one tool sensor and the at least one probe sensor to a global tracking coordinate system.

19. The method of claim 16 , further comprising:
a global tracking system including a plurality of tool sensors integrated with the interventional tool, wherein the generation of the at least two multi-planar reformatting images includes:
generating the at least two multi-planar reformatting images normal to the interventional tool relative to the tool sensors; and
