The technology concerns improvements in the system and methods for analyzing data derived from a Magnetoencephalogram (MEG).

The basic premise of the invention is that there exists a replicable correspondence between the amplitude and sources of absolute powers of the electrical signal and the magnetic B vector and that a set of proper scaling factors may be applied to convert one to the other. The invention describes how to systematically quantify and analyze power spectra and spectra obtained from a set of MEG sensors, the construction of standardized features such as absolute power, relative power, coherence and symmetry in frequency bands analogous to those conventionally used in QEEG (Quantitative EEG Measures) and the statistical evaluation of each such feature relative to an existing QEEG age-appropriative normative database. The improvements described in this invention would enable clinicians to analyze patients more rapidly than currently possible and would enable automatic and sensitive statistical evaluation, thereby facilitating clinical interpretability as well as making the use of MEG more cost-effective.
