“…Optical skin phantoms were treated by pulsed laser radiation. Subsequent thermographic imaging [29][30][31][32][33][34] of the irradiated area was used to measure the temporal profiles during and after the irradiation. The laser-pulse parameters were varied to determine the optimal values for tissue irradiation which would provide best results of therapy.…”

“…Additionally, the physical distention of the artery can create a small heat signature as the heat is transmitted to a wider surface area and then is transmitted to the surrounding tissues. This heat signature forms the basis of the non-contact approach to pulse measurement that is pursued in this thesis work [8].…”

“…This core temperature is then transferred to the skin through the tissues of the body. Muscles, bone, and fat tend to serve as insulators and keep hotter temperatures near the core, while the circulatory system tends to provide the main source to convect heat to the body's surface where it can be detected through thermal imaging systems [8]. The skin directly above the vessels of the circulatory system tends to be hotter than the surrounding skin because the blood is heated in the core and then carries that heat to the surface of the skin.…”

“…From a physiological standpoint, skin tissues and the fat of the subcutaneous tissues act as heat insulators, which effectively help maintain the body's normal core temperature. As the skin is exposed to the environment, it approaches the ambient temperature [Wu08]. While the typical anatomical structure involves a layer of fat between the muscle fascia and the skin, the thickness of this layer is extremely …”

“…These models use heat fluxes originating from the blood, metabolism, and body's core as inputs to the system and heat fluxes due to thermal radiation, air, and sweat evaporation that emanate from the system; the net transfer in and out of the system must be equivalent as in (2.13). Wu et al (2008) show that using some basic assumptions and practical imaging conditions (i.e. indoor imaging at rest with air-conditioning), that the amount of heat transferred via blood perfusion alone can be calculated as a function of the temperature read from the thermal camera.…”
