ABSTRACT:
A method and system for the evaluation and visual display of abnormal electromagnetic physiological activity of the brain and the heart utilizes a set of bioelectric amplifiers and a computer based system for the recording and analog to digital conversion of human electrophysiological signals. The signals collected are expanded in selected spatio-temporal functional bases, and parametric models are used for summarizing the statistical properties of the coefficients. Multivariate topographic maps and curves are computed based on the comparison of the estimated parameters for a patient and the regression equations for the parameters calculated from a normative database. The multivariate maps and curves are visually displayed in a diagnostically useful color-coded probability scale.
