A biomagnetic field measurement processing apparatus includes circuitry; and a memory storing computer-executable instructions that cause the circuitry to execute reconfiguring a current signal from a biomagnetic field signal; extracting a current component from the current signal; and based on the extracted current component, adding to each other at least two current waveforms among current waveforms of a plurality of inward currents that are current components directed toward a nerve axon from around the nerve axon, or adding to each other at least two current waveforms among current waveforms of a plurality of inward currents that are current components directed toward a muscle fiber from around the muscle fiber, and generating a current waveform to be displayed on a display device, according to the at least two current waveforms added to each other.

A magnetic field calibration device is used to calibrate a magnetism measurement device having a plurality of magnetic sensors and includes a first holder having a first holding surface, a second holder having a second holding surface having a fixed relative positional relation with the first holding surface, and magnetism generating parts fixed to the first holding surface and the second holding surface. Thus, calibration can be completed with a single operation by assigning the first and second holding surfaces of the magnetic field calibration device respectively to the first and second measurement surfaces of the magnetism measurement device. In addition, since the relative positional relation between the first and second holding surfaces is fixed, measurement results obtained from the individual measurement surfaces match each other.

An electromagnetic bio-signal detector to monitor very weak evoked action potentials associated with neurotransmissions is described. The small induction-coil array detector and integrated circuit design enables the device to have a small and possibly portable form factor while minimizing cost. Advanced signal processing methods enables the device to detect very weak electromagnetic signals without the need for shielding to reduce electromagnetic background emissions. The combination of cost, size, and sensitivity affords the electromagnetic bio-signal detector broad utility both inside and outside hospital settings and for numerous diagnostic and treatment feedback applications.

A method and a system for detecting the possible existence of a stroke is provided. In a first step of the method, a first measurement of a nerve impulse is obtained from the skin of a first location of a patient using a magnetometer. In a second step, the first measurement is compared with either a baseline measurement or a second measurement of a nerve impulse obtained from the skin of a second location of the patient using a magnetometer. In a third step, a signal is transmitted indicating a possible stroke if there is no symmetry between the first measurement and either the baseline measurement or the second measurement.
