ABSTRACT:
A method for classifying field patterns generated by electrophysiological activities occurring inside the body of a living subject includes the steps of measuring field patterns arising as a result of the electrophysiological activities outside the body of the subject using a multi-channel measuring apparatus, generating feature vectors corresponding to the measured field patterns, supplying the feature vectors to an adaptive classifier, and training the adaptive classifier with training field patterns which have been generated by a localizable surrogate model of the electrophysiological activity. The method includes the further step of generating a probability value for each field pattern at an output of the adaptive classifier which indicates the probability with which each field pattern can be generated by a selected localizable surrogate model. This classification method greatly reduces the number of possible patterns which must be reviewed by a physician in order to evaluate the electrophysiological activity of the subject.
