Title (EN) METHOD AND SYSTEM FOR LIMITING INTERFERENCE IN ELECTROENCEPHALOGRAPHIC SIGNALS
(FR) PROCEDE ET SYSTEME PERMETTANT DE LIMITER L'INTERFERENCE DANS LES SIGNAUX ELECTROENCEPHALOGRAPHIQUES
Abstract: front page image
(EN)This invention provides methods and systems for removing or limiting interference and artifacts often found in EEG signals and/or EOG signals and/or other physiological signals, and produces output signals that can be of greater use for analytic or diagnostic purposes, such as sleep studies. Interference and artifacts are removed by applying a plurality of filtering methods targeted to the particular time-frequency characteristics of the anticipated interference.
(FR)La présente invention concerne des procédés et des systèmes qui permettent d'éliminer ou de limiter l'interférence et les artéfacts qu'on trouve souvent dans les signaux EEG et/ou dans les signaux EOG et/ou dans d'autres signaux physiologiques et qui produisent des signaux de sortie d'une plus grande utilité aux fins d'analyse et de diagnostic, comme dans les études sur le sommeil. L'interférence et les artéfacts sont éliminés par application d'une pluralité de procédés de filtrage ciblés sur les caractéristiques particulières de temps fréquence de l'interférence anticipée.
