A comparison of vector and radial magnetometer arrays for whole-head magnetoencephalography

PDF Version Also Available for Download.

Description

The number of detectors in magnetometer arrays for magnetoencephalography (MEG) has been steadily increasing, with systems containing or more detectors now possible. It is of considerable interest to know how best to configure such a large array. In particular, is it useful to measure all three components of the magnetic field, rather than just the radial component? This paper compares the information content provided by three different magnetometer arrays for whole-head measurements, using a definition of information content developed by Kemppainen and Ilmoniemi.
