Background: Breast cancer is a common malignancy in which early breast cancer detection by the help of imaging can improve the treatment outcome. Thermography utilizes infrared beams which are fast, non-invasive, and non-contact and the output created images by this technique are flexible and useful to monitor the temperature of the human body. Case presentation: Our patient is a 25-year-old w...
In this paper, an overview of the recent applications of pulsed infrared thermography is presented. Pulsed infrared thermography, which provides stratigraphic information by analyzing the heat diffusion process within the sample after a thermal perturbation, is applied to the investigation of different kinds of cultural heritage artefacts. In particular, it is used to analyze repairs, decorativ...
The natural convection flow phenomena that occur inside an enclosed space are very interesting examples of complex fluid systems that may yield to analytical, empirical and numerical solutions, and many reports have looked into this basic problem. In the present study, heat transfer and fluid flow for natural convection in a horizontal rectangular container with a free surface are investigated ...
Eye temperature, measured using infrared thermography (IRT), is a non-invasive tool for evaluating the stress response in cattle, bison and elk to surgical procedures. Infrared thermography has recently revealed that a rapid drop in eye temperature is likely a sympathetically mediated response via vasoconstriction that can be used to detect fear and/or pain related responses in animals to diffe...
Within recent years there has been an increase in the use of NDT methods to detect defects and anomalies in various civil engineering structures. Infrared thermography, which has been successfully used in the USA in civil engineering applications, is being increasingly applied in the UK as an NDT technique. For example, the technique is now included in the Building Regulations for the assessmen...
Thermal barrier coatings (TBCs) are used in gas turbine engines to protect engine hot-section components in the harsh combustion environments, and extend component lifetimes. Infrared Thermography method has been selected for obtaining thermal images and studying the TBCs of Alumina, Zirconia and Alumina+Titanium oxide coated on the base plate of Titanium, by measuring the back wall temperature...
RATIONALE Varicella zoster virus is a neurotropic virus that causes an infectious disease characterized by skin changes and neuropathic pain. After the resolution of the first infection, the virus lies dormant within the sensory ganglia. The reactivation of the virus causes zoster. An alteration in skin infrared emission might be expected in the areas of the skin affected by inflammatory change...
Thermography (infrared imaging) is a non-invasive technique applied for the detection breast cancer. We consider the problem of automatically recognition malignant breast from frontal view thermography image presented as gray scale image. This framework provides insights into several issues: breast Region of Interest (ROI) detection, extraction statistical features, extraction features based on...
OBJECTIVE It was the aim of this study to investigate the surface temperature in newborns within the first hour after delivery. Furthermore, the influence of different environmental conditions with regard to surface temperature was documented. METHODS Body surface temperature was recorded under several environmental conditions by use of infrared thermography. 42 newborns, all delivered at ter...
