A computer-aided automatic vital acupuncture point alignment and electronic acupuncture method uses a system comprised of a computer, a digital imaging device, a digital probe device and an electronic acupuncture device. The computer takes a picture of a patient's body with the digital imaging device and automatically marks vital acupuncture points on the picture from a standard body's picture on which all vital acupuncture points are marked and localizes the vital acupuncture points on the patient's skin with the digital probe device. A practitioner uses the electronic acupuncture device to touch the vital acupuncture points on the patient's skin based on the patient's picture. The computer outputs a suitable wave signal through the electronic acupuncture device to the skin. Therefore, the present invention identifies the vital acupuncture points on the skin to have a good curative effect.
