POROUS STONE N.P. Avdelidis, E.T. Delegou, and A. Moropoulou 1 IRT & Materials Consultancy, Volos, Greece; 2 National Technical University of Athens, Athens, Greece Abstract: In this work, infrared thermography was employed as a monitoring technique during water capillary rise tests on a choice of porous stones in the laboratory, as well as in situ on a cleaned porous stone surface of a histori...

Since BC 400 when Hippocrates used temperature in a diagnosis by applying mud to a patient's body and speculating that dry areas had disease, temperature has been an important area of interest in medicine. The skin is a very important organ in temperature regulation, and body temperature is controlled by the combined control of the central and autonomic nerve system. Infrared thermography (IRT)...

Eddy current thermography testing is an emerging technology in nondestructive testing. This technology combines eddy current and thermographic NDT techniques to provide a fast and efficient method for defect detection and characterisation over a relatively large area. The technique uses induced eddy currents to heat the sample being tested and defect detection is based on the changes of the ind...

Thermography is being increasingly appreciated as a further modality contributing to the early detection of incipient tissue damage predisposing to diabetic foot ulceration in selected high-risk patients. Among currently available modalities, liquid crystal thermography and infrared thermography have been most widely used. The former is effective, but its main limitation is low sensitivity. The...

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...

In urban search and rescue situations, a 3D map obtained using a 3D range sensor mounted on a rescue robot is very useful in determining a rescue crew’s strategy. Furthermore, thermal images captured by an infrared camera enable rescue workers to effectively locate victims. The objective of this study is to develop a 3D thermography mapping system using a 3D map and thermal images; this system ...

Eight Danish Holstein cows were milked with a 1-mm thick specially designed soft liner on their right rear teat and a standard liner mounted under extra high tension on their left rear teat. Four of the animals were overmilked for 5 min. Rear teats were subjected to ultrasound examination on the first day and to infrared thermography on the second day. Teats were submersed in ethanol 20 min pos...

Non-destructive testing (NDT) refers to all the test methods, which permit testing or inspection of object without impairing its future usefulness. The aim of NDT is the detection of damages or unwanted irregularities like flaws, inclusions, material loss/degradation and local imperfections in material properties. Active infrared thermography is a nondestructive evaluation technique in which ma...
