A system for positioning electrodes on a patient body includes an image capturing system, a memory device, a processing system and an indicator system. The image capturing system generates an actual image of the patient body. The memory device stores a reference image, the reference image including a reference body and a reference position on the reference body. The processing system compares the actual image and the reference image and for determining an electrode position on the patient body by matching the reference position on the reference body. The indicator system indicates the electrode position on the patient body.
