Eugene, Oregon - November 18, 2008 - New techniques for imaging the functional activity of the human brain by simultaneously recording changes in its electrical activity (EEG) and blood flow (fMRI) are contributing important insights into normal and pathological brain functioning. However, the EEG signal recorded with existing EEG/fMRI technologies is often of disappointing quality.
Today, EGI announced that it had licensed a key patent from The Regents of the University of California covering methods for improving the signal quality of the EEG when it is recorded during an MRI exam (U.S. Patent No. 7,286,871, “Method and apparatus for reducing contamination of an electrical signal”). The licensed techniques, developed by Dr. Mark Cohen of UCLA’s David Geffen School of Medicine, allow the artifact introduced into the recorded EEG signal by the large gradient pulses emitted by the MRI during its normal operation to be effectively removed from the data using timing pulses generated by the MRI. Additional claims in the patent protect the use of “twisted” pairs electrodes to help improve the signal-to-noise ratio, which also results in cleaner EEG recordings. [company pr] MORE
