1. A system for providing a multi-level current density diagram of a human body organ for the purpose of medical diagnosis comprising:

  • a. means for attaching a plurality of electrodes to a patient'"'"''"'"'s body in positions around the organ to detect continuous analogtype voltage signals resulting from electrical energy generated by the organ in the course of its functioning;

    b. digital converting and recording apparatus connected to the electrodes, said apparatus inCluding means to multiplex a discrete portion of said signals, means to convert the multiplexed portion into digital form representing the magnitude thereof, and means to record the signals in digital form;

    c. digital computer means to convert the recorded digital data into a series of multi-level current density diagrams, said computer being preset with respect to the time intervals of discrete portions of the recorded data and with respect to the correlative geometrical locations of the electrodes and with respect to the resistivity of the body parts between the electrodes and the organ to convert the voltage representations to current density representations.
