Abstract
A method comprises: selecting a plurality of electrodes of one or more stimulation leads, the selected plurality of electrodes defining a two-dimensional region; determining a calibration value for stimulation points defined by the plurality of electrodes; selecting a stimulation point within a boundary formed by the two-dimensional region; identifying points on the boundary that are axially displaced relative to the selected stimulation point; automatically calculating boundary calibration values for identified points, each boundary calibration value being calculated as a linear interpolation of calibration values of a pair of stimulation points determined for the plurality of electrodes; automatically assigning a calibration value to the selected stimulation point that is a summation of the calculated boundary calibration values; and using the automatically assigned calibration value for the stimulation point to control an amplitude of stimulation pulses applied to the patient.
