A method of determining and treating disordered tissue in a patient incites energy signal generation from disordered tissue. An energy sensor structure obtains an energy signal from tissue of a patient. The obtained energy signal is compared in a processor circuit to a known energy signal of the same tissue under normal functioning of the tissue. The tissue is identified as disordered tissue when the comparing step determines that the obtained energy signal is different from the known energy signal. The disordered tissue is localized within the patient via the energy signal. A bodily disorder caused by the localized disordered tissue is diagnosed by an Al module. The bodily disorder is then treated.

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.
