Abstract
Thermography is a technique that involves using a thermal camera to make a thermogram image that depicts the quantity of infrared energy emitted, transmitted, and reflected by an object. Body surface temperature monitoring, which varies when blood flow increases or decreases due to clinical irregularities, has been frequently utilised to diagnose medical problems such as breast cancer, diabetes neuropathy, and peripheral vascular disorders using thermography. Thermography has become a significant tool, particularly for fever screening during infectious disease epidemics such as Ebola and COVID-19, due to its non-invasive and non-contact nature. Thermography is a sensory instrument that can be particularly valuable in protecting human health when paired with thermal physiology data. In this review, we analyze and compare several thermography processes and aspects to come up with the optimal methodology for use in the medical field.
