Abstract
A biomagnetometer measures a magnetic field produced by a source within the body of a subject, using a magnetic field sensor system. The biomagnetometer includes an ultrasonic transceiver that determines the internal physical structure of the body with ultrasonic waves. An electromagnetic transmitter/receiver establishes the position of the ultrasonic transceiver relative to the magnetic field sensor system. A computer controls and integrates the magnetic field sensor system, the ultrasonic transceiver, and the electromagnetic transmitter/receiver. The biomagnetometer permits a direct association between the measured biomagnetic field and the location of the source within the body of the subject.
