Abstract

A computer implemented system and method facilitates a cycle of generation, sharing, and refinement of volumes related to stimulation of anatomical tissue, such as brain or spinal cord stimulation. Such volumes can include target stimulation volumes, side effect volumes, and volumes of estimated activation. A computer system and method also facilitates analysis of groups of volumes, including analysis of differences and/or commonalities between different groups of volumes.

Claims

1. A method, comprising:

obtaining atlas registration information regarding a patient and obtaining a surgical trajectory for implantation of a leadwire;

obtaining user input of at least one desired therapeutic effect;

obtaining effects of electrical stimulations performed on a plurality of patients of a patient population;

analyzing, by a processor, the effects of electrical stimulations performed on the plurality of patients of the patient population to determine a plurality of volumes of activation (VOAs) along the surgical trajectory and utilizing the atlas registration information, wherein each of the VOAs corresponds to an estimate of a volume of tissue stimulated using a corresponding set of stimulation parameters;

scoring each of the VOAs to reflect production of the at least one desired therapeutic effect by stimulation of the VOA;

based on the analysis and scoring, determining, by the processor, a target volume and a corresponding set of stimulation parameters that are estimated to provide electrical stimulation of the target volume; and

stimulating the patient using the corresponding set of stimulation parameters for the target volume.

2. The method of claim 1, wherein obtaining atlas registration information comprises identifying an AC-PC (anterior commissure-posterior commissure) in an image of the patient.

3. The method of claim 1, wherein obtaining atlas registration information comprises obtaining an image of the patient and registering the image to an atlas.

4. The method of claim 1, wherein obtaining atlas registration information comprises comparing the patient to a plurality of population groups of the patient population, wherein an atlas is associated with each of the population groups, and selecting the atlas of the population group that is most similar to the patient.

5. The method of claim 4, wherein obtaining atlas registration information comprises transforming an image of the patient to register the image to the atlas of the population group that is most similar to the patient.

6. The method of claim 1, further comprising obtaining user input of at least one side effect, wherein the scoring of the VOAs also reflects production of the at least one side effect by stimulation of the VOA.

7. The method of claim 1, wherein determining the target volume comprises selecting points for the target volume that belong to a threshold number or percentage of the VOAs.

8. The method of claim 1, wherein determining the target volume comprises selecting points for the target volume that have a threshold score based on the VOAs containing the point weighted by the scoring of the VOA.

9. The method of claim 1, further comprising filtering the VOAs by a time of day when electrical stimulation of the VOA was performed.

10. The method of claim 1, further comprising filtering the VOAs by a medication used by a patient associated with the VOA.

11. A system, comprising:

at least one computer processor; and

a memory coupled to the at least one computer processor and having instructions stored thereon, wherein the instructions are configured to perform the following acts when executed by the at least one computer processor;

obtaining a surgical trajectory for implantation of a leadwire;

obtaining user input of at least one desired therapeutic effect;

obtaining effects of electrical stimulations performed on a plurality of patients of a patient population;

analyzing the effects of electrical stimulations performed on the plurality of patients of the patient population to determine a plurality of volumes of activation (VOAs) along the surgical trajectory and utilizing atlas registration information, wherein each of the VOAs corresponds to an estimate of a volume of tissue stimulated using a corresponding set of stimulation parameters;

scoring each of the VOAs to reflect production of the at least one desired therapeutic effect by stimulation of the VOA;

based on the analysis and scoring, determining a target volume and a corresponding set of stimulation parameters that are estimated to provide electrical stimulation of the target volume; and

stimulating the patient using the corresponding set of stimulation parameters for the target volume.

12. The system of claim 11, wherein the at least one computer processor is configured and arranged to perform the following additional act:

obtaining the atlas registration information regarding the surgical trajectory for implantation of the leadwire.

13. The system of claim 11, wherein obtaining the atlas registration information comprises obtaining an image of the patient and registering the image to an atlas.

14. The system of claim 12, wherein obtaining the atlas registration information comprises comparing the patient to a plurality of population groups of the patient population, wherein an atlas is associated with each of the population groups, and selecting the atlas of the population group that is most similar to the patient.

15. The system of claim 14, wherein obtaining atlas registration information comprises transforming an image of the patient to register the image to the atlas of the population group that is most similar to the patient.

16. The system of claim 11, further comprising obtaining user input of at least one side effect, wherein the scoring of the VOAs also reflects production of the at least one side effect by stimulation of the VOA.

17. The system of claim 11, wherein determining the target volume comprises selecting points for the target volume that belong to a threshold number or percentage of the VOAs.

18. The system of claim 11, wherein determining the target volume comprises selecting points for the target volume that have a threshold score based on the VOAs containing the point weighted by the scoring of the VOA.
