Title
(EN) METHOD AND SYSTEM TO CALCULATE QEEG
(FR) PROCÉDÉ ET SYSTÈME POUR CALCULER UN QEEG
Abstract
(EN)
A system (20) and method (600) for calculating a quantitative EEG is disclosed herein. EEG signals are generated from an EEG machine (40) comprising electrodes (35), an amplifier (42) and processor (41). The EEG signals are processed continuously for artifact reduction to generate continuous artifact reduced EEG data. A quantitative EEG is computed using continuous artifact reduced EEG data in near real time.

La présente invention concerne un système (20) et un procédé (600) pour calculer un EEG quantitatif. Les signaux EEG sont générés par un appareil EEG (40) comprenant des électrodes (35), un amplificateur (42) et un processeur (41). Les signaux EEG sont traités en continu pour la réduction des artefacts afin de générer des données EEG continues à artefacts réduits. Un EEG quantitatif est calculé en utilisant les données EEG continues à artefacts réduits pratiquement en temps réel.
