If the comparing step determines that the obtained energy signal is different from the known energy signal, the tissue is identified as diseased tissue. The diseased tissue is localized in the patient via the energy signal. A physical disability caused by the localized diseased tissue is diagnosed by an AI module. The physical disability is then treated.
