Eagle DDFAO systemic health scanning system uses low voltage DC original stimulus induction technology. It induces a sustained electrical stimulation of 1.28 volts in the 22 individual zone of the body through the 6 electrodes, and the electrical signals in the body change into the ion flow. Based on the ion flow in the anodic and cathodic polarization movement, it can explicitly measure the resistance of the organization, electrical conductivity, pH value, voltage and cell membrane action potential, and then forming the three-dimensional image of the various parts of the body. Eagle DDFAO systemic health scanning system just needs 5 minutes to scan the whole body. It can make an accurate assessment of the biological activity and function of various organization and organs, to forecast the potential risk factors and disease development direction. It can make early warning of the risk of disease.
