Fully automated localization of electroencephalography (EEG) electrodes

A method for identifying electrode locations for electroencephalography (EEG) from three-dimensional head images, comprising:

• inputting three dimensional images stored in an electronic format,
• wherein the images are derived from a single imaging modality;
• executing, via a processor, instructions software encoded on a computer readable medium for:
• automatically identifying precise locations of a plurality of EEG electrodes positioned on a patient's head solely from the inputted three dimensional images;
• wherein the automatically identifying precise locations comprises
• using object shapes and properties intrinsic to the EEG electrodes to locate the electrodes in the three dimensional images without use of exogenous markers, and
• calculating centroid locations of each of the located plurality of EEG electrodes;
• and
• generating a three dimensional image as a function of the identified precise locations of the plurality of EEG electrodes;
• wherein the three dimensional image comprises
• a reconstruction of the plurality of located EEG electrodes and
• orientation information;
• wherein the single imaging modality consists of magnetic resonance imaging (MRI);
• wherein the orientation information is acquired by:
• convolving the calculated centroid locations with a mask matching a three dimensional rotation of a single electrode.
