Abstract

A system and method for generating an estimated volume of activation (VOA) corresponding to settings applied to a stimulation leadwire includes a processor performing the following: determining, for each of a plurality of neural elements, one or more respective parameters characterizing an electrical distribution along the neural element, looking up the one or more parameters for each of the neural elements in a look-up table (LUT), obtaining threshold values for each of the neural elements recorded in the LUT in association with the looked-up parameters, comparing, for each of the neural elements, a value of the leadwire settings to each of the respective threshold value, estimating based on the comparisons which of the neural elements would be activated by the settings, and generating a structure corresponding to a region including the neural elements estimated to be activated.

Claims

1. A computer system for generating an estimated volume of activation (VOA), the system comprising:

a computer processor configured to;

for each of a plurality of neural elements that are in a vicinity of a leadwire;

determine a respective threshold activation value; and

determine whether a user-input stimulation value to be applied to the leadwire meets the respective threshold activation value of the respective neural element; and

generate a surface structure corresponding to those of the neural elements whose respective threshold activation values have been determined to be met by the user-input stimulation value.

2. The system of claim 1, wherein the leadwire is arranged to provide an anodic stimulation.

3. The system of claim 1, wherein the user-input stimulation value includes one of a current amplitude and a voltage amplitude.

4. The system of claim 1, wherein the user-input stimulation value includes a respective distinct stimulation value for each of a plurality of contacts of the leadwire.

5. The system of claim 4, wherein the respective distinct stimulation values include current values.

6. The system of claim 1, wherein the leadwire is configured to provide a deep brain stimulation (DBS) therapy.

7. The system of claim 1, wherein the leadwire is configured to provide a spinal cord stimulation (SCS) therapy.

8. The system of claim 1, wherein the leadwire is configured to provide an Occipital NS therapy.

9. The system of claim 1, wherein the leadwire is configured to provide a Trigemenal NS therapy.

10. The system of claim 1, wherein the leadwire is configured to provide a peripheral field stimulation therapy.

11. The system of claim 1, wherein the leadwire is configured to provide a sacral root stimulation therapy.
