Electrical and activation field models for configuring stimulation therapy
First Claim
1. A method comprising:
- receiving a patient anatomy data set that describes at least one characteristic of patient tissue proximate to an electrical stimulation lead implanted within a patient;
receiving user input that defines stimulation parameter values;
generating a stimulation field model that represents where electrical stimulation will propagate from the electrical stimulation lead based upon the patient anatomy data set and stimulation parameter values; and
displaying the stimulation field model on a representation of an anatomical region of the patient.

Abstract
The disclosure describes a method and system that generates an electrical field model of defined stimulation therapy and displays the electrical field model to a user via a user interface. The electrical field model is generated based upon a patient anatomy and stimulation parameters to illustrate which areas of a patient anatomical region will be covered by the electrical field during therapy. In addition, a neuron model may be applied to the electrical field model to generate an activation field model. The activation field model indicates which neurons will be activated by the electrical field in the anatomical region. These field models may be used by a clinician to determine effective therapy prior to stimulation delivery. In particular, the field models may be beneficial when programming non axi-symmetric, or three-dimensional (3D), leads which allow greater flexibility in creating stimulation fields.
