Methods for automatic generation of EEG montages

A computer-implemented method of enabling a generation of at least one user-defined montage from a plurality of EEG electrodes positioned in a patient's brain, on the patient's brain and/or on the patient's scalp, said method comprising:

• generating a first graphical interface to visually display at least one view of the patient's brain and/or scalp overlaid with a spatial distribution of the plurality of EEG electrodes, wherein each of said plurality of EEG electrodes in the at least one view is uniquely identified with reference to its position in the patient's brain, on the patient's brain and/or on the patient's scalp;
• displaying a tool within the first graphical interface;
• receiving an input from a user using the tool to select at least one electrode from the plurality of EEG electrodes displayed in the at least one view;
• prompting the user to indicate at least one reference electrode corresponding to the selected at least one electrode wherein using the tool to select the at least one electrode comprises:
• allowing the user to use at least two drawing loops to select electrodes corresponding to a first montage and electrodes corresponding to a second montage;
• upon forming the at least two drawing loops, generating a second graphical interface to prompt the user to identify the at least one electrode and the at least one reference electrode from the electrodes enclosed by each of the at least two drawing loops;
• and
• upon identifying the at least one electrode or the at least one reference electrode, automatically designating the other electrode(s);
• accessing EEG signals corresponding to the at least one electrode and the at least one reference electrode;
• and
• generating a third graphical interface to display at least one EEG trace indicative of a comparison of EEG signals of the at least one electrode and the at least one reference electrode.

A computer-implemented method of enabling a real-time generation of at least one user-defined bipolar montage from a plurality of EEG electrodes positioned in a patient's brain, on the patient's brain and/or on the patient's scalp, said method comprising:

• generating a first graphical interface to display at least one view of said patient's brain and/or scalp overlaid with a plurality of identifications corresponding to the plurality of EEG electrodes, wherein each of said identifications uniquely references each of the plurality of EEG electrodes in the patient's brain, on the patient's brain and/or on the patient's scalp;
• displaying a tool within the first graphical interface, wherein the tool is configured to receive a user's input that selects a first identification and a second identification;
• prompting the user to indicate a reference identification from the selected first identification and the second identification, wherein using the tool to select the first identification and the second identification comprises a) enabling the user to use a first drawing loop to select the first identification and the second identification for generating a montage, b) upon forming the drawing loop, generating a second graphical interface to prompt the user to identify the active electrode or reference electrode of the first identification and the second identification enclosed by the drawing loop, and c) upon identifying the active electrode or the reference electrode, automatically designating the other electrode;
• acquiring EEG signals associated with the plurality of EEG electrodes corresponding to the first identification and the second identification;
• and
• generating a third graphical interface to display an EEG trace associated with the first identification, the second identifications and the reference identification, wherein the plurality of EEG electrodes include at least one of strip, grid or depth electrodes.
