Abstract

A system and method for graphically identifying candidate electrodes of a leadwire for stimulation of a patient anatomy includes a processor obtaining data corresponding to an anatomic region, identifying a spatial relationship between electrodes of the leadwire to the anatomic region, based on the identifying, selecting a subset of the electrodes of the leadwire, generating, based on the obtained data and the selected subset, a graphical output arrangement that includes a model of the leadwire including graphical representations of at least some of the electrodes and a graphical selection marking identifying the selected subset of the electrodes.

Claims

1. A computer-implemented method for graphically identifying candidate electrodes of a leadwire for stimulation of a patient anatomy, the method comprising:

obtaining, by a computer processor, data corresponding to an anatomic region;

identifying, by the processor, a spatial relationship between electrodes of the leadwire to the anatomic region;

based on the identifying, selecting, by the processor, a subset of the electrodes of the leadwire;

generating, by the processor and based on the obtained data and the selected subset, a graphical output arrangement that includes;

a model of the leadwire including graphical representations of at least some of the electrodes; and

a graphical selection marking identifying the selected subset of the electrodes; and

displaying, by the processor, the graphical output arrangement on a display coupled to the processor.

2. The method of claim 1, wherein:

the electrodes are arranged in succession along a length of the leadwire, between first and second ends of the leadwire; and

the generation and arrangement of the graphical selection marking is performed to ensure that;

a first end of the selection marking is arranged adjacent the electrode of the selected subset that, of the selected subset, is arranged closest to the first end of the leadwire; and

a second end of the selection marking is arranged adjacent the electrode of the selected subset that, of the selected subset, is arranged closest to the second end of the leadwire.

3. The method of claim 2, wherein the graphical selection marking includes:

a first line arranged perpendicular to a longitudinal axis of the model of the leadwire and arranged adjacent to the electrode of the selected subset that, of the selected subset, is arranged closest to the first end of the leadwire; and

a second line arranged perpendicular to the longitudinal axis of the model of the leadwire and arranged adjacent to the electrode of the selected subset that, of the selected subset, is arranged closest to the second end of the leadwire.

4. The method of claim 2, wherein the graphical selection marking includes a line extending from the first end of the selection marking to the second end of the selection marking.

5. The method of claim 1, wherein the anatomic region is a region targeted for stimulation.

6. The method of claim 1, wherein the anatomic region is an anatomic structure targeted for stimulation.

7. The method of claim 1, wherein the anatomic region is defined by an association of the region with at least one adverse stimulation side effect.

8. The method of claim 1, wherein the anatomic region is defined by an association of the region with at least one therapeutic stimulation effect.

9. The method of claim 1, wherein the graphical output arrangement further includes a second graphical selection marking identifying one of the subset of the electrodes based on the spatial arrangement of the one of the subset of the electrodes with a sub-area of the anatomic region.

10. The method of claim 9, wherein the sub-area is a centroid of the anatomic region.

11. The method of claim 1, wherein, where the leadwire includes at least one electrode that passes through the anatomic region, only the at least one electrode is selected in the selecting step.

12. The method of claim 11, wherein the electrodes of the leadwire include at least one virtual electrode defined by activations of a combination of two or more of the electrodes.

13. The method of claim 1, wherein, where the leadwire does not include any electrodes that passes through the anatomic region, the selecting is performed such that each of the subset of the electrodes is at least partially included within a portion of the leadwire that is between a first line of projection that is perpendicular to a central longitudinal axis of the leadwire and extends to a first boundary of the anatomic region and a second line of projection that is perpendicular to the central longitudinal axis of the leadwire and extends to a second boundary of the anatomic region.

14. The method of claim 1, wherein the graphical output arrangement includes a graph, the model of the leadwire provides a first set of values of the graph, a set of values of a stimulation parameter are a second set of values of the graph, and the graphical output arrangement includes one or more nodes that each corresponds to a respective value pair including one of the first set of values and one of the second set of values.

15. The method of claim 14, wherein a node corresponds to a value of the first set of values if the node is associated with a stimulation conducted with an electrode to which the value of the first set of values corresponds.

16. The method of claim 15, wherein a node corresponds to a value of the second set of values if the node is associated with a stimulation conducted with the stimulation parameter being set to the value of the second set of values.

17. The method of claim 14, wherein a node corresponds to a value of the first set of values if the node is associated with a stimulation region centered at an electrode to which the value of the first set of values corresponds.

18. The method of claim 14, wherein the stimulation parameter is stimulation amplitude.

19. The method of claim 14, wherein each of at least one of the one or more nodes is selectable, in response to which selection, the processor is configured to display details of a record associated with the respective value pair of the respective node.

20. The method of claim 14, wherein each of at least one of the nodes represents one of a recorded adverse side effect of a stimulation conducted at the respective value pair and a recorded therapeutic effect of the stimulation conducted at the respective value pair.

21. The method of claim 14, wherein the graphical selection marking includes a first edge parallel to a first axis of the graph and a second edge parallel to a second edge of the graph.

22. The method of claim 21, wherein, where the one or more nodes includes at least one node whose respective value pair includes a value of the first set of values that corresponds to at least one of the subset of the electrodes, the at least one node is displayed within the graphical selection marking.
