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

Figure 1

(a) A typical configuration of the internal region relative to the source space for a helmet-type sensor array. As can be seen, an appropriate location of the origin can be found such that the internal region covers the whole source space. (b) A possible configuration of the internal region relative to the source space in case of a flat sensor array. The internal region cannot entirely cover the source space, which extends into an intermediate region. In these figures, the inner circle with a broken line indicates the boundary between the internal and intermediate regions. The outer circle with a broken line indicates the boundary between the intermediate and external regions.
