ElectroMeridian Imaging Electromeridian ImagingŪ (ryodoraku) was initially developed in Japan in 1951 by Dr. Yoshio Nakatani and has been recently innovated by Dr. John A. Amaro of The International Academy of Medical Acupuncture Inc. It helps to reduce the human errors and bias possible in Eastern medicine diagnostics and makes evaluation procedure more reliable. It produces an exact reading of 24 "yuan" or source points on wrists, feet, and ankles to determine an imbalance in meridians. It measures the effectiveness of acupuncture treatments and helps patient to see progress as well as areas requiring further attention. The procedure is computerized and completely painless. The device used is "Ryodoraku with Stimulation" which is the top of the line for stand-alone ryodoraku devices. In our office, we are exclusively using the PC interface which sends measurement results directly to the computer and makes them error-proven.
