A system (10) and method of providing therapy to a patient using a plurality of electrodes (26) implanted within the patient. A virtual mul- tipole configuration is defined relative to the plurality of electrodes. The distance between each of a group of the electrodes and a virtual pole of the virtual multipole configuration is determined. A stimulation amplitude distribution is determined for the electrode group based on the determined distances, thereby emulating the virtual multipole configuration. Electrical energy is conveyed from the electrode group in accordance with the computed stimulation amplitude distribution. |
