System and method for determining target stimulation volumes
First Claim
1. A computer-implemented method for determining a stimulation volume for a subject patient, the method comprising:
- associating, by a computer processor, anatomical features in a first image, corresponding to an anatomical region of the subject patient, with corresponding anatomical features in a second image, corresponding to an anatomical region of at least one selected patient from a patient population, wherein a stimulation volume has been predetermined for the at least one selected patient; and
warping, by the processor, a combination of the second image and the stimulation volume predetermined for the at least one selected patient so that the anatomical features in the second image of the combination match the anatomical features in the first image, the warped combination thereby providing for the subject patient one of a target stimulation volume, defined by an outline of a region targeted to be activated by a stimulation, and a side effect stimulation volume, defined by an outline of a region, activation of which by a stimulation is estimated to cause a side effect.

Abstract
A system and method may include determining a target stimulation volume based on modifying a patient population image for which an efficacious volume had been determined. A system and method for suggesting stimulation devices may include determining which stimulation device is capable of producing an output volume of activation that most closely matches the target volume. A system and method for facilitating selection of stimulation parameters may include graphically identifying a maximum volume in which tissue is stimulatable by an implanted stimulation device. A system and method may pre-compute volumes of activation that result from a predetermined modification of programming settings. A system and method may transmit stimulation programming settings from a stimulation programming module to a stimulation generating device.

8. A computer-implemented method for determining a stimulation volume for a subject patient, the method comprising:
-
associating, by a computer processor, anatomical features in a first image, corresponding to an anatomical region of the subject patient, with corresponding anatomical features in a second image, corresponding to an anatomical region of at least one selected patient from a patient population, wherein a stimulation volume has been predetermined for the at least one selected patient; modifying, by the processor, the second image so that spatial relationships of the anatomical features in the second image match spatial relationships of the anatomical features in the first image; modifying a spatial relationship of the stimulation volume to the second image based on the modification to the second image to generate a new spatial relationship; and determining for the subject patient one of a target stimulation volume, defined by an outline of a region targeted to be activated by a stimulation, and a side effect stimulation volume, defined by an outline of a region, activation of which by a stimulation is estimated to cause a side effect, by applying the new spatial relationship to the modified second image.
