1. BACKGROUND AND RATIONALE In the proposed work, vital health sign related to cardiovascular activities will be sensed and quantified with the application of a non-invasive and minimal contact based method. In the new technology, an intensive investigation will be done to find a method to diagnose coronary diseases, stenosis and blockages through thermal heat transfer performance of the skin above the carotid artery on the neck of human subjects (as a probable region of measurement) using an IR temperature sensor/thermography.
