Abstract

A system and method include a shape sensing enabled device too ( 102 ) having an optical fiber ( 126 ). An interpretation module ( 115 ) is configured to receive optical signals from the optical fiber within a structure and interpret the optical signals to determine a shape of the device. An image generation module ( 140 ) is configured to receive the shape of the device, register the shape with an image volume of the structure and generate a curved Memory multi-planar reconstruction (CMPR) rendering based on the shape.

First claim

The invention claimed is:

1. A system, comprising:
a shape sensing enabled device having at least one optical fiber;
an interpretation module configured to receive optical signals from the at least one optical fiber within a structure and interpret the optical signals to determine a shape of the device; and
an image generation module configured to receive the shape of the device, register the shape with an image volume of the structure and generate a curved multi-planar reconstruction (CMPR) rendering based on the shape.

2. The system as recited in claim 1 , wherein the image volume includes a three-dimensional image of the structure taken by one or more of computed tomography, magnetic resonance imaging, fluoroscopy, nuclear imaging and ultrasound.

3. The system as recited in claim 1 , wherein the shape sensing enabled device includes an elongated instrument including one or more of an endoscope, a catheter and a guide-wire.

4. The system as recited in claim 1 , wherein the shape sensing enabled device includes an imaging device configured to collect images at the shape sensing enabled medical device.

5. The system as recited in claim 1 , wherein the shape sensing enabled device collects path information for the structure in three-dimensional space, about an axis of the at least one optical fiber and over time.

6. The system as recited in claim 1 , wherein the structure includes a vascular or endoluminal structure.

7. The system as recited in claim 6 , wherein the image generation module rescales image data to account for movement in the vascular or endoluminal structure.

8. The system as recited in claim 1 , wherein the image generation module rescales image data to account for movements in the structure.

9. The system as recited in claim 1 , wherein the shape sensing enabled device collects path information to register and fuse non-Cartesian images with Cartesian images based upon the path information.

10. A workstation, comprising:
a shape sensing system including:
a shape sensing enabled medical device having at least one optical fiber; and
an interpretation module configured to receive optical signals from the at least one optical fiber within a structure and interpret the optical signals to determine a shape of the medical device;
a curved multi-planar reconstruction (CMPR) rendering module includes:
an image generation module configured to receive the shape of the medical device, register the shape with an image volume of the structure, the CMPR being generated from the image volume using the shape as path information; and
a display for viewing the CMPR.

11. The workstation as recited in claim 10 , wherein the image volume includes a three-dimensional image of the structure taken by one or more of computed tomography, magnetic resonance imaging, fluoroscopy, nuclear imaging and ultrasound.

12. The workstation as recited in claim 10 , wherein the shape sensing enabled device includes an elongated instrument including one or more of an endoscope, a catheter and a guide-wire.

13. The workstation as recited in claim 10 , wherein the shape sensing enabled medical device includes an imaging device configured to collect images at the shape sensing enabled medical device.

14. The workstation as recited in claim 10 , wherein the path information for the structure includes three-dimensional space, rotation about an axis of the at least one optical fiber and time.

15. The workstation as recited in claim 10 , wherein the structure includes a vascular or endoluminal structure.

16. The workstation as recited in claim 15 , wherein the image generation module rescales image data to account for movement in the vascular or endoluminal structure.

17. The workstation as recited in claim 10 , wherein the shape sensing enabled device collects path information to register and fuse non-Cartesian images with Cartesian images based upon the path information.

18. A method, comprising:
collecting shape sensing data from a shape sensing device disposed within a three-dimensional structure;
registering the three-dimensional structure having the shape sensing device therein with an image volume; and
generating a curved multi-planar reconstruction (CMPR) image from the shape sensing data such that the shape sensing data provides a path along which image volume data is employed to provide an image of the three-dimensional structure.

19. The method as recite din claim 18 , further comprising rendering cross-sections of the structure along the path.

20. The method as recited in claim 19 , wherein the image volume includes a three-dimensional image of the structure taken by one or more of computed tomography, magnetic resonance imaging, fluoroscopy, nuclear imaging and ultrasound.

21. The method as recited in claim 19 , wherein the shape sensing device includes an elongated device including one of an endoscope, a catheter and a guide-wire.

22. The method as recited in claim 19 , further comprising refining the CMPR each time a new shape is acquired for the shape sensing device.

23. The method as recited in claim 19 , wherein the path for the structure includes information over time for three-dimensional space, and rotation about an axis of the shape sensing device.

24. The method as recited in claim 19 , further comprising rescaling image data to account for movements in the structure.

25. The method as recited in claim 19 , further comprising adjusting volume parameters during an acquisition of the image volume to limit collecting of volume data to regions intersecting with the shape sensing device.
