Transcript

  • 1. REACT: R eal-time E EG A nalysis for Event Dete ct ion Andrey Temko, Robert P. McEvoy , Denis Dwyer, Stephen Faul, Gordon Lightbody, William P. Marnane First AMA-IEEE Medical Technology Conference on Individualized Healthcare, Washington, D.C., 22nd March 2010 Department of Electrical & Electronic Engineering University College Cork, IRELAND
  • 2. Motivation
    • Seizure: A brief electrical discharge of a group of neurons in a synchronized manner
    • Neonates: Most prominent feature of neurological dysfunction
    • Adults: Approximately 1% of world population suffers from epilepsy
    REACT Real-time EEG Analysis for Event Detection Point-of-Care Technology
  • 3. REACT Technology Smoothing & thresholding Support Vector Machine 55 features (frequency envelope, wavelet, model-based (AR), structural, time-domain, etc.) Filtering, re-sampling, segmentation A.
