Abstract
This review describes the features of modern infrared imaging technology and
the standardization protocols for thermal imaging in medicine. The technique
essentially uses naturally emitted infrared radiation from the skin surface.
Recent studies have investigated the influence of equipment and the methods
of image recording. The credibility and acceptance of thermal imaging in
medicine is subject to critical use of the technology and proper understanding
of thermal physiology. Finally, we review established and evolving medical
applications for thermal imaging, including inflammatory diseases, complex
regional pain syndrome and Raynaud’s phenomenon. Recent interest in the
potential applications for fever screening is described, and some other areas
of medicine where some research papers have included thermal imaging as
an assessment modality. In certain applications thermal imaging is shown
to provide objective measurement of temperature changes that are clinically
significant.
