摘要
Systems, methods, and devices are disclosed for optimizing patient-specific stimulation parameters for spinal cord stimulation. A patient-specific anatomical model is developed based on a pre-operative image, and a patient-specific electrical model is developed based on the anatomical model. The inputs to the electric model are chosen, and the model is used to calculate a distribution of electrical potentials within the modeled domain. Models of neural elements are stimulated with the electric potentials and used to determine which elements are directly activated by the stimulus. Information about the models inputs and which neural elements are active is applied to a cost function. Based on the value of the cost function, the inputs to the optimization process may be adjusted. Inputs to the optimization process include lead/electrode array geometry, lead configuration, lead positions, and lead signal characteristics, such as pulse width, amplitude, frequency and polarity.
