1. A method for providing therapy to a target neural tissue of a patient, the method comprising:
determining placement of at least two pairs of electrodes based on interrogating 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;
affixing at least two pairs of electrodes noninvasively on a body of the patient at respective locations relative to the target neural tissue based on the placement of the at least two pairs of electrodes determined by interrogating the TI pattern database;
applying a first particular input waveform having a first amplitude and a first frequency to a first pair of the at least two pairs of electrodes; and
applying a second particular input waveform having a second amplitude and a second frequency to a second pair of the at least two pairs of electrodes, the second frequency configured to be different from the first frequency 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.
