Abstract: Long Wave IR imaging is one of the imaging modalities that have been used to study medical conditions of a human body by means of body surface temperature measurement. The thermal image obtained from a thermal imager can be better described as the heat map of the captured ROI (Region of Interest).
These thermal markers could be potential indicators of existing medical condition and can give further insights about the illnesses. While the literature review reports of extensive study of thermal imaging as subordinate tool for disease diagnosis, it cannot be denied that there still is dearth of standard thermal image databases of human body with medical conditions characterized by elevated temperatures in affected body parts which could be a useful research aid.
This could be attributed to the highly expensive Thermal Imagers commercially available. Therefore attempts to design and develop a reliable and cost-effective thermal sensor could be a pragmatic step towards widespread availability of thermal imaging device for use in medical applications.
In this paper, we have attempted to review the research works which has reported application of thermal imaging for medical purposes. We have also summarized the thermal imagers used and the temperature range and resolution of thermal sensors utilized in their reported works.
