Analysis of the Correlation between the Facial Temperature and the Stenosis of Carotid Arteries

Death caused by stroke above the age of 60 years placed second in the world, and is the fifth leading cause in people aged 15 to 59 years old. Several methods for early detection of stroke are magnetic resonance angiography, and carotid duplex, both diagnoses are cost and time consuming. This research is aimed to provide a noninvasive, cost effective, and rapid technique for diagnosing carotid artery stenosis by using thermography. In this study, 64 images from 32 people were used to analysis the correlation between the temperature of the face and the stenosis of carotid arteries by automatically selecting and calculating the mean and standard deviation of the facial temperature. We find that external carotid artery affects the facial temperature significantly
