Abstract

A method and system for a user interface for artifact removal in an EEG is disclosed herein. The invention allows an operator to select a plurality of artifacts to be automatically removed from an EEG recording using a user interface. The operator pushes a button on the user interface to apply a plurality of filters to remove the plurality of artifacts from the EEG and generate a clean EEG for viewing.

Claims

1. A method for removing artifacts in an EEG recording, the method comprising:

selecting a plurality of artifacts to automatically be removed from an EEG recording using a user interface;

selecting a display mode from a plurality of display modes for presenting the EEG recording, wherein the plurality of display modes comprise seizure probability, rhythmicity spectrogram left hemisphere 1-25 Hz, rhythmicity spectrogram right hemisphere 1-25 Hz, relative asymmetry spectrogram, hemispheric 0-18 Hz, peak envelope hemispheric 2-20 HZ, spike detections, and chewing artifact probabilities;

generating an EEG recording from an EEG system comprising

a plurality of electrodes for generating a plurality of EEG signals,

at least one amplifier connected to each of the plurality of electrodes by a plurality of wires to amplify each of the plurality of EEG signals,

a processor connected to the amplifier to generate an EEG recording from the plurality of EEG signals, and

a display connected to the processor for displaying an EEG recording;

displaying the EEG recording on the display, the EEG recording comprising a plurality of artifacts wherein the plurality of artifacts comprises at least two of a muscle artifact, an eye movement artifact, an electrical artifact, a heartbeat artifact, a tongue movement artifact, and a chewing artifact;

applying a plurality of filters to the EEG recording to automatically remove the plurality of artifacts, wherein the processor is configured to apply the plurality of filters to the EEG recording; and

generating a clean EEG recording on the display for viewing.
