Abstract

A system and method for outputting historical stimulation information includes a processor configured to assign individual display regions, e.g., pixels or voxels, (or a larger region) a score based on those volumes of activations (VOA) in which the individual display region had been included and the scores assigned to those VOAs, and display in a display device a map of varying graphical indicia based on the different scores assigned to the elemental display regions.

First claim

What is claimed is:

1. A computer-implemented method for outputting a stimulation history map corresponding to a plurality of stimulations that have been performed using a stimulation device implanted in an anatomical region, the method comprising:
for each of a plurality of display elements, where each of the display elements is recorded as having been part of each one of a plurality of scored estimated volumes of tissue activated (VOAs) by the plurality of stimulations, determining, by a computer processor, a score for the display element based on scores of the plurality of VOAs of which the display element has been recorded as being a part, wherein each of the plurality of VOAs comprises multiple ones of the display elements; and
generating and outputting, by the processor, a map including the plurality of display elements graphically marked based on the respective scores determined for the display elements.

2. The method of claim 1 , wherein the display elements are pixels.

3. The method of claim 2 , wherein the pixels represent an anatomical region in which the stimulation device is implanted.

4. The method of claim 2 , wherein the pixels represent an atlas of an anatomical region in which the stimulation device is implanted.

5. The method of claim 1 , wherein the display elements are voxels.

6. The method of claim 5 , wherein the voxels represent an anatomical region in which the stimulation device is implanted.

7. The method of claim 5 , wherein the voxels represent an atlas of an anatomical region in which the stimulation device is implanted.

8. The method of claim 1 , wherein the display elements represent tissue fibers.

9. The method of claim 1 , wherein the display elements represent neural elements.

10. The method of claim 1 , wherein the determining includes, for each of the display elements, determining the score for the display element as a maximum score for that display element from the plurality of VOAs of which the display element has been recorded as being a part.

11. The method of claim 1 , wherein the determining includes, for each of the display element, determining the score for the display element as a minimum score for that display element from the plurality of VOAs of which the display element has been recorded as being a part.

12. The method of claim 1 , wherein the determining includes calculating an average of scores of all of the plurality of VOAs of which the respective display element has been recorded as being a part.

13. The method of claim 1 , wherein the scores of the VOAs depend on a degree of therapeutic effect recorded as having been caused by the respective VOAs.

14. The method of claim 13 , further comprising:
receiving input of one of a plurality of therapeutic effects as a filter criterion, wherein, in accordance with the filter criterion, only those of the scores of the VOAs which correspond to the therapeutic effect are used for the determination of the scores for the display elements.

15. The method of claim 1 , wherein the scores of the VOAs depend on a degree of adverse side effect recorded as having been caused by the respective VOAs.

16. The method of claim 15 , further comprising:
receiving input of one of a plurality of adverse side effects as a filter criterion, wherein, in accordance with the filter criterion, only those of the scores of the VOAs which correspond to the adverse side effect are used for the determination of the scores for the display elements.

17. The method of claim 1 , wherein scores of the VOAs reflecting a degree of therapeutic effect caused by the stimulations to which the VOAs correspond and scores of the VOAs reflecting a degree of adverse side effect caused by the stimulations to which the VOAs correspond are used for the determination of the scores for the display elements.

18. The method of claim 1 , wherein the scores of the VOAs are affected by degrees of therapeutic effect and degrees of adverse side effect recorded as having been caused by stimulations to which the VOAs correspond.

19. The method of claim 1 , wherein display elements not having recorded as having been included in a scored VOA are blocked out from view in the map.

20. The method of claim 1 , wherein the graphical markings include indicia defined by at least one of color and shading.

21. A computer-implemented method for outputting a stimulation history map corresponding to a plurality of stimulations that have been performed using a stimulation device implanted in an anatomical region, the method comprising:
for each of a plurality of display elements, where each of the display elements is recorded as having been part of each one of a plurality of scored estimated volumes of tissue activated (VOA) by the plurality of stimulations:
determining, by a computer processor, a score for the display element based on scores of the plurality of VOAs of which the display element has been recorded as being a part, wherein each of the plurality of VOAs comprises multiple ones of the display elements; and
determining, by the processor, whether the score determined for the display element meets a threshold; and

generating and outputting, by the processor, a map of the display elements, wherein the display elements whose respective scores have been determined to meet the threshold are graphically distinguished from those of the display elements whose respective scores have been determined not to meet the threshold and from those of the display elements for which a score has not been determined.

22. The method of claim 21 , wherein the map is three-dimensional.
