“…Although, absolute temperatures obtained by thermography depend on a large number of factors, the relative temperature differences measured at the same point, at the same surface, have been shown reliable [16]. Among several suggested methods, special attention was given to occlusion by tourniquet, which was proposed as a valuable method for evaluating of skin blood flow, at sudden changes in perfusion condition [15]. Previous studies have shown, that vascular occlusion in the upper arm, established by 3-minute tourniquet, leads to reactive hyperemia on the palms and fingertips.…”

“…All measurements were obtained under controlled experimental conditions of the environment, at room temperature (26.84 °C ± 4.81 SD) and humidity of 22 %, according to the usual recommendations for such a kind of testing [15]. Measuring procedures were based on the previous research and modified with additional steps needed because of longer tourniquet duration.…”

The physiological reaction of postocclusive local reactive hyperemia is regulated by neurovascular mechanisms and it reflects the function of microcirculation. Thermoregulatory changes occur first, in the form of increased skin surface temperature, which is usually followed by an increase in local blood flow. This study investigated a correlation between tourniquet duration on the upper arm, and the appearance of reactive hyperemia in the distal parts of the upper limb. Changes were registered with infrared thermometer and infrared thermography, which provided us a highly precise view of distribution of reactive hyperemia. Changes of oxygen saturation of peripheral arterial blood and blood pressure were also recorded. Our research has shown that longer duration of tourniquet leads to more intense and longer lasting reactive hyperemia in the palmar region, followed by higher temperatures of the skin surface, without any changes in postocclusive values of SpO2. Keywords: Infrared thermography, Microcirculation, Postocclusive hyperemia, Skin temperature, Tourniquet, Thermoregulatory changes.

“…For the proper heat distribution within the body, blood flow plays a very crucial role. This research paper discusses how infrared thermography can be used in the analysis of blood flow in the lower limp positions [36]. For the easy understanding of the temperature behaviour of skin, dynamic infrared thermography is used [37].…”

Fever is a common symptom for various infectious diseases that are reporting nowadays in a massive amount like COVID-19, Ebola and so on that will directly affect our whole human cells and are showing a lot of chromosomal aberrations too. Since there was not a unique way are to predict how these diseases will affect our body both physically and mentally, since they can create some aftereffects in future too, there should be a suitable system which will efficiently detect these type of pandemic. In all these situations thermal screening had emerged as a remedial method for the detection of temperature variations. Among this Infrared thermography had been used as the best and effective method for fever screening. This survey presents some of the important papers which discussed how Infrared thermography can be effectively utilized for the detection of these epidemics by analyzing the temperature variations done in fever screening. Infrared thermography (IRT) is a method which uses an imaging scheme that gives you an image which is a thermal diagram that shows the temperature variations of various intensities. IRT uses the basic working principle from Stefan-Boltzmann Law, where the relationship between the temperature and the emissive power is established and the camera which is the infrared camera will capture this infrared energy and is converted into corresponding electronic signals. This paper gives a brief idea about various techniques used for fever screening which can be used to detect various diseases.

“…The objective of this research is to determine and track the overheating spots using an infrared imaging system during radiology examination. There are some similar approaches involving the tracking of body temperature (e.g., [37]) using a particle filter to track the selected the region of interest (ROI) [38] or combined with a Kalman filter to mitigate the effect of noise in tracking and thermal measurements [39] in the human body. The proposed approach creates a thermal dataset from several volunteers in a lying position (similar to radiology imaging environments) in front of thermal camera.…”

Thermal imagery for monitoring of body temperature provides a powerful tool to decrease health risks (e.g., burning) for patients during medical imaging (e.g., magnetic resonance imaging). The presented approach discusses an experiment to simulate radiology conditions with infrared imaging along with an automatic thermal monitoring/tracking system. The thermal tracking system uses an incremental low-rank noise reduction applying incremental singular value decomposition (SVD) and applies color based clustering for initialization of the region of interest (ROI) boundary. Then a particle filter tracks the ROI(s) from the entire thermal stream (video sequence). The thermal database contains 15 subjects in two positions (i.e., sitting, and lying) in front of thermal camera. This dataset is created to verify the robustness of our method with respect to motion-artifacts and in presence of additive noise (2–20%—salt and pepper noise). The proposed approach was tested for the infrared images in the dataset and was able to successfully measure and track the ROI continuously (100% detecting and tracking the temperature of participants), and provided considerable robustness against noise (unchanged accuracy even in 20% additive noise), which shows promising performance.
