Title: Method for aiding diagnostic scanning of the body of a patient

Abstract: A circuit having an amplifier coupled to an oscillator, the oscillator having a second amplifier and a feedback circuit. Changes in resistance between an electrode coupled to the circuit and a probe, also connected to the circuit, are responded to by the circuit. Output components are connected to the circuit for providing visual and audio signals corresponding to the resistance changes and for recording the changes upon a chart. The electrode is grasped by a patient, and the probe is the hand of a doctor using the technique of palpation upon the patient. The probe alternately is a structure, placed against the patient by the doctor, for simultaneously detecting the changes in resistance between the electrode and the structure and providing a second resistance change corresponding to the temperature of the portion of the patient contacted by the structure, the circuit responding to either resistance change to provide output signals corresponding to either the resistivity or the temperature of the contacted portion of the patient.
