Title:
SYSTEM AND METHOD FOR EEG IMAGING OF CEREBRAL ACTIVITY USING ELECTRODE SETS
Document Type and Number:
WIPO Patent Application WO2006060727
Kind Code:
A9
Abstract:
The invention provides a method of estimating cerebral sources of electrical activity from a small subset of EEG channels utilizing existing methods to provide a 3dimensional, discrete, distributed, linear solution to the inverse problem using inputs consisting of a small number of EEG channels (e.g., 4 channels) augmented with synthetic EEG data for the other channels. The resultant image of cerebral electrical activity in the region of the EEG channels from which data is recorded is of comparable spatial resolution in the corresponding region to images of cerebral electrical activity obtained using a complete set of EEG channels (e.g., using 24 channels).
