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 ...

Thermography, a pictorial display of the infrared radiation of the breast, has been used for approximately 25 years as an aid in the evaluation of breast problems. Its inception dates to Lawson’s observations in 1956-1958 that a breast cancer may be warmer than surrounding tissue.’-’ He also showed that the venous blood draining the cancer may be warmer than its arterial supply. Many investigat...

AIMS AND OBJECTIVES To date assessment of changes in ocular temperature, as a hallmark of uveitis in horses has not been determined. Therefore the aim of the current study was to determine whether ocular temperature is increased in acute uveitic eyes compared with non-uveitic eyes, and to compare an affordable thermometry device with a thermography device. MATERIAL AND METHODS Ocular temperat...

Radiofrequency ablation (RFA) and microwave ablation (MWA) are currently the dominant modalities to treat unresectable liver tumors. Monitoring the ablation process with b-mode-sonography is often hampered by artefacts. Furthermore, vessels may cause cooling in the adjacent tumor target (heat-sink-effect) with risk of local recurrence. The present study evaluated infrared-thermography to monito...

Breast cancer is one of the leading causes of death among women. Early diagnosis can increase the survival rate in cancer patients. Digital Infrared Thermal Imaging (DITI) is a portable and non-invasive diagnostic technology that is non-contact, pain-free and radiation free procedure for breast carcinoma diagnosis. However, the link between disease and heat radiation is complex and in many case...

frared thermography, mapped 32 dermatome segments on the body’s surface that approximated the areas of innervation of the major peripheral nerves. He studied 32 healthy subjects and 30 patients with peripheral nerve impairment. In normal persons, he found the skin temperature difference between sides of the body to be stable, varying only 0.24C + 0.073C. In contrast, patients with peripheral ne...

PURPOSE To evaluate the feasibility to detect activated brown adipose tissue (BAT) using single-time-point infrared thermography of the supraclavicular skin region under thermoneutral conditions. To this end, infrared thermography was compared with 18-F-FDG PET, the current reference standard for the detection of activated BAT. METHODS 120 patients were enrolled in this study. After exclusion...
