Signal Space Separation Method for a Biomagnetic Sensor Array Arranged on a Flat Plane for Magnetocardiographic Applications: A Computer Simulation Study

Figure 6

The internal component and the external component of the signal vector (plus sensor noise) with four different locations of the origin (0, 0, and zori): (a) zori = 0 cm, (b) zori = 3 cm, (c) zori = 6 cm, and (d) zori = 9 cm. The upper panel indicates the internal components, and the lower indicates the external components . The filled circle shows the location of the origin, and the square indicates the location of the source. In each pair of the sensor time courses, they are normalized to the maximum value from the upper panel, and the ordinate indicates the normalized values.
