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...
Equine thermography has increased in popularity recently because of improvements in thermal cameras and advances in image-processing software. The basic principle of thermography involves the transformation of surface heat from an object into a pictorial representation. The colour gradients generated reflect differences in the emitted heat. Variations from normal can be used to detect lameness ...
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...
The human hand is considered to be the terminus of the nervous system. It contains numerous capillary vessels, and it plays an important role in the regulation of the autonomic nervous system. We have used infrared thermography and ultrasound Doppler flowmetry to investigate characteristics of the temperature variation of the hand and the blood flow after cold stimuli. We have also developed an...
This paper presents a method for detecting defects in reinforced concrete structures by using the method of active infrared (IR) thermography. Non-destructive testing using infrared (IR) thermography consists of thermal stimulation of the object of interest and monitoring of the surface temperature variation during the transient cooling or heating process. The paper includes short descriptions ...
Fusion of NDT techniques has proven to increase the capability and reliability of defect detection thus improve inspection results. It can also provide solution for the limitations posed by a single NDT technique in acquiring the intended information and so achieving the required inspection efficiency. Eddy current thermography is an emerging technology in advanced NDT, which provides and alter...
OBJECTIVE Safety and feasibility evaluation of intracoronary temperature measurements in patients with acute coronary syndromes (ACS) using a catheter based thermography system. METHODS AND RESULTS Thermography was performed in 40 patients with ACS. A 3.5-F thermography catheter containing 5 thermocouples measuring vessel wall temperature, and 1 thermocouple measuring blood temperature (accur...
Breast cancer is a common malignancy causing high mortality in women especially in developed countries. Due to the contribution of mammographic screening and improvements in therapy, the mortality rate from breast cancer has decreased considerably. An imaging-based early detection of breast cancer improves the treatment outcome. Mammography is generally established not only as diagnostic but al...
INTRODUCTION Methods allowing one to locate the position of a cutaneous perforator do not allow one to determine the boundaries of the vascularized skin. In clinical practice this causes complications in the form of marginal necrosis of the flap. AIM To examine the usefulness of thermography to assess the extent of vascularization of the skin and subcutaneous tissue by a single perforator. ...
Potential use of thermography for more effective detection of breast carcinoma was evaluated on 26 patients scheduled for breast carcinoma surgery. Ultrasonographic scan, mammography and thermography were performed at the University Hospital for Tumors. Thermographic imaging was performed using a new generation of digital thermal cameras with high sensitivity and resolution (ThermoTracer TH7102...
