MAGNETOMETER FOR MEDICAL USE

Each induction coil 2 is coupled to a respective detection circuit comprising a low impedance pre-amplifier 3, a low pass filter 5, a notch filter 6 to remove line noise, and an averaging element 7. Each detection circuit produces an output signal 9 for use to analyze the time varying magnetic field...

Zusammenfassung:Each induction coil 2 is coupled to a respective detection circuit comprising a low impedance pre-amplifier 3, a low pass filter 5, a notch filter 6 to remove line noise, and an averaging element 7. Each detection circuit produces an output signal 9 for use to analyze the time varying magnetic field of the region of the subject's body.
