Claim 12:
13. A system comprising:
a memory storing a temporal interference (TI) pattern database having a plurality of TI patterns for different combinations of electrode placement configurations, number of electrode pairs, a range of amplitudes corresponding respectively to a first input waveform and a second input waveform, and a range of frequencies corresponding respectively to the first input waveform and the second input waveform;
a neuromodulator for providing therapy to a target neural tissue of a patient by using a temporal interference (TI) pattern operative to be caused by at least two input sources comprising a first input source operative to generate a first input waveform having a first amplitude and a first frequency and a second input source operative to generate a second input waveform having a second amplitude and a second frequency; and
at least two pairs of patch electrodes attachable proximate to the target neural tissue of the patient, the at least two pairs of patch electrodes coupled to respective input sources via corresponding leads, and wherein placement of at least two pairs of patch electrodes is determined based on interrogating a temporal interference (TI) pattern database,
wherein the neuromodulator includes a controller configured to control the first and second input sources to generate and apply the first and second input waveforms to the respective pairs of patch electrodes such that the first and second input waveforms combine, when substantially simultaneously applied, to generate a beat waveform having a beat frequency due to interference, the beat waveform causing a TI electric field having an interference region at least partially overlapping the target neural tissue of the patient, wherein the beat frequency is of a value operative to impart a therapeutic effect to the target neural tissue.
