15 July 2014 – Electrical Geodesics, Inc. (“EGI” or the “Company”), a leading neurodiagnostic medical technology company, today announces the award of a $1.75 million SBIR grant from the US National Institute of Neurological Disorders and Stroke/National Institutes of Health (“NINDS/ NIH”) to support the development of a revolutionary technology to perform dense array EEG within high-field MRI environments.

Simultaneous use of dense array EEG with MRI scanning is becoming increasingly important in both the scientific understanding of neurophysiology in managing conditions such as epilepsy and the non-invasive, presurgical planning for brain surgery. Typically, EEG electrodes are connected with metallic wires that interfere with the magnetic field within the MR scanners, increasing the risk of tissue heating, causing errors and artifacts in the highly sensitive dEEG recordings and MR images.

EGI has prototyped the use of an “Ink Net” design using customized high-resistive conductive inks printed on polymer film to connect electrodes to the EEG amplifier. These polymer inks have the potential to deliver the required quality of signal with minimal interference with the magnetic fields. Working with Massachusetts General Hospital (“MGH”), EGI will use this grant funding over the next 2 to 3 years to refine the development and validation of its Geodesic Sensor Net technology to create a range of Ink Net products for clinical and research use.

Don Tucker, PhD, Chairman and CEO of EGI, said:

“We have a number of on-going collaborations with neurologists and neurosurgeons both in the US and internationally, which demonstrate the value of dense-array EEG alongside MR imaging in delivering accurate images of the electrical activity of the brain. Better technologies are needed to optimize the use of the tools already available to the neuroscience community and the award of this grant and support of experts at MGH will allow us to research and prove new substrates and inks and develop and validate the next generation of EEG signal technology.”
