Abstract

A system for providing visual three dimensional assistance to a user during a medical procedure involving a soft organ. The system and method provide visual assistance to a user during a medical procedure involving a soft organ. The system and method utilize a processor for generating an image of the soft organ, a surgical instrument tracker for tracking a surgical instrument during the medical procedure, and a display in communication with the processor and the surgical instrument tracker for visually displaying in three dimensions, the image of the soft organ and the surgical instrument in relation to the soft organ.

Claims

1. A system for providing visual assistance to a user during a medical procedure involving a soft organ comprising:

a processor for generating a three dimensional image of the soft organ;

a surgical instrument tracker for tracking a surgical instrument in a three dimensional space during the medical procedure;

a display in communication with the processor and the surgical instrument tracker for visually displaying, in three dimension, the three dimensional image with the soft organ and the surgical instrument in relation to the soft organ in a three dimensional space.

2. The system of claim 1, wherein the display further provides quantitative information during the medical procedure.

3. The system of claim 2, wherein the quantitative information is risk analysis information.

4. The system of claim 2, wherein the quantitative information is soft organ volume information.

5. The system of claim 2, wherein the quantitative information is at least one of the following:

references information, guidance information, or alert information.

6. The system of claim 1, wherein

the three dimensional image of the soft organ includes the soft organ and surrounding anatomical structures;

and

the three dimensional image has segmented soft organ and segmented surrounding anatomical structures.

7. The system of claim 6, wherein the surrounding anatomical structures include internal or external structures relative to the soft organ.

8. The system of claim 1, where the three dimensional image is rotatable and scalable.

9. The system of claim 1, wherein the display contains at least a first image and a second image.

10. The system of claim 9, wherein the first image is a global perspective image and the second image is a local perspective image.

11. The system of claim 10, wherein the surgical instrument comprises a tip and wherein the local perspective image is a close up view of the surgical instrument'"'"'s tip relative to the soft organ.

12. The system of claim 9 wherein the first image and the second image can be synchronously manipulated.

13. The system of claim 1, wherein the image of the soft organ is generated based on a computed tomography (CT) image or a magnetic resonance imaging (MRI) image.

14. The system of claim 1 wherein the processor for generating a three dimensional image of the soft organ overlays preoperative information on the three-dimensional image.

15. The system of claim 1 wherein the three dimensional image of the soft organ is combined with a second image obtained from a separate image source.

16. The system of claim 15, wherein the second image is an ultrasound image.

17. The system of claim 1, wherein the processor further compares the user'"'"'s interactions during the medical procedure with the three dimensional image and generates a signal in response to the comparison.

18. The system of claim 17, wherein the user'"'"'s interactions include the placement of the surgical instrument in relation to the soft organ.

19. The system of claim 17 wherein the signal is an audio or visual alarm.

20. A machine-readable tangible and non-transitory medium, having information for providing visual assistance to a user during a medical procedure, recorded thereon, wherein the information, when read by the machine, causes the machine to perform the following:

generate a three dimensional image of the soft organ;

track a surgical instrument in a three dimensional space during the medical procedure; and

display, via a display device, in three dimensions, the three dimensional image with the soft organ and the surgical instrument in relation to the soft organ in a three dimensional space.

21. A method implemented on a machine having at least one processor, storage, and a communication platform connected to a network for providing visual assistance to a user during a medical procedure involving a soft organ comprising:

generating on a display in communications with the processor, a three-dimensional image of the soft organ;

tracking, via a surgical instrument tracker, a surgical instrument in a three dimensional space during the medical procedure;

combining, via the processor, the three-dimensional image of the soft organ and the tracked surgical instrument in three dimensional space; and

displaying, in three dimension, the three dimensional image with the soft organ and the surgical instrument in relation to the soft organ in a three dimensional space.
