Summary

In the proposed method of sensing the vital health sign related to cardiovascular diseases, thermal heat transfer performance of the skin will be evaluated using a non-contact based Infra-Red temperature sensor. The temperature of the skin is significantly dependent upon the heat source as blood vessels (veins and capillaries) in the vicinity of the skin. However, there are several locations in the human body, where arteries are also at a relatively less depth from the outer skin surface (radial or ulnar arteries at the wrist and carotid artery in the neck). If it is possible to track the flow of blood from the thermal performance of the skin, then it could be useful in predicting various states of the human health related to cardiovascular activities.

Subjects will undergo Existing Procedure EP- Passive Thermography PT for Phase I and Existing Procedure EP- Active Thermography ATLIC/ATPC for Phase II, with Duplex Ultrasound being the existing procedure that is considered as more reliable in clinical practice. Existing Passive Thermography will be used to setup the baseline data for Phase I. The currently under-development temperature mapping method (Active Thermography) that involves application of cooling (either pulsed or lock-in cooling) over the skin will be utilized for Phase II.
