Paranasal sinusitis detection using thermal imaging

This paper focuses on the identification of paranasal sinusitis using thermal imaging. Thermal imaging is a non-invasive technique which provides a 2D temperature profile of a body under measurement. The experiments have been performed by IR camera on eight subjects of different age group under consideration of constant ambient temperature and resting position. The Region of Interest for imaging is human face. The average temperature of different parts of a face is measured by circle and polygon analysis. The line analysis is performed horizontally and vertically across the nose to show the temperature variations between nose and adjacent parts to it. Image thresholding is done by using Otsu´s method to differentiate between normal and sinusitis affected patients. The preliminary investigation results show encouraging signs for use of thermal imaging for paranasal sinusitis.
