Signal Space Separation Method for a Biomagnetic Sensor Array Arranged on a Flat Plane for Magnetocardiographic Applications: A Computer Simulation Study
(a) Locations of four interference sources shown with respect to the sensors. (b) Random (normalized) time courses assigned to the four interference sources. (c) Generated interference sensor data . These interference sensor data are computed by projecting the interference-source time courses in (b) through the sensor lead field obtained using the Biot-Savart law. The sensor time courses are normalized, and the ordinate indicates the normalized values.
