Infrared thermal imaging in medicine
Physiological Measurement, 2012This 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.

Infrared thermal imaging without pixellation
Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Technical Digest (IEEE Cat. No.01CH37170), 2001Summary form only given. A large pixel-less thermal imager based on the epitaxial integration of GaAs/AlGaAs quantum-well infrared photodetector and a GaAs light-emitting diode is demonstrated. The device transforms a mid-infrared (9 /spl mu/m) scene at to a near-infrared (0.82 /spl mu/m) image.

Thermal imaging is a non-contact method in which the radiation pattern of an object is converted into a visible image called thermal image or thermogram. All the objects at temperature above absolute zero (−273 °C) emit infrared radiation. The infrared band with wavelength from 3 to 14 µm is called thermal infrared region.

Thermal Infrared Imaging of Exoplanets
AIP Conference Proceedings, 2009High‐contrast imaging remains the only way to search for and study weakly‐irradiated giant exoplanets. We review here in brief a new high‐contrast imaging technique that operates in the 3–5 μm window and show the exquisite sensitivity that can be reached using this technique.

Digital infrared thermal imaging of human skin
IEEE Engineering in Medicine and Biology Magazine, 2002Describes computational approaches to image processing for improved interpretation and analysis. The authors discuss the physics of image formation, developments in uncooled camera technology, and the use of image processing to interpret 2-D maps of temperatures and to analyze thermal images for assessing physiological changes and responses to physical

Infrared thermal imaging in sepsis
2022Microcirculatory dysfunction is important in the pathophysiology of sepsis, yet it is not quantified in clinical practice. The skin has a rich microcirculatory blood supply, with subjective assessment of skin temperature used as a marker of perfusion.

Infrared Imaging Analysis for Thermal Comfort Assessment
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007Skin temperature is a relevant and effective indicator for objective evaluation of human sensations and thermal states according to the surrounding thermal stresses. Managed by skin blood flow, sympathetic nervous system (constriction and sweating), subcutaneous thermal structure and facial vein patterns, facial coetaneous temperature variability can ...

Human thermal models for evaluating infrared images
IEEE Engineering in Medicine and Biology Magazine, 2002Discusses comparing infrared images under various thermal environmental conditions through normalization of skin surface temperature. To evaluate IR images obtained under various thermal environmental conditions, we proposed a human thermal model with which IR images obtained under certain thermal environmental conditions can be converted into images ...
