The Value of Thermography as a Clinical Imaging Diagnostic Test:
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...
متن کاملPhotoacoustic thermography of tissue.
Photoacoustic (PA) techniques can measure temperature in biological tissues because PA signal amplitude is sensitive to tissue temperature. So far, temperature-measuring PA techniques have focused on sensing of temperature changes at a single position. In this work, we photoacoustically measured spatial distribution of temperature in deep tissue. By monitoring the temperature at a single positi...
متن کاملThermography in Neurologic Practice
One kind of medical images that has been developed in the last decades is thermal images. These images are assessed by infrared cameras and have shown an exponential development in recent years. In this sense, the aim of this study was to describe possibilities of thermography usage in the neurologic practice. It was performed a systematic review in Web of Knowledge (Thompson Reuters), set in a...
متن کاملDouble Pulse Infrared Thermography
0. Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an optimum interval delta is chosen. The observed ...
متن کاملLock-in Thermography Image Procesing
Composite materials have appropriate thermal properties for detection flaws by means of non-destructive infrared thermography methods. Infrared thermography methods are based on tracking heat flow that has been induced by flood lamps. Lock-in thermography, as one of infrared thermography methods, is used in detection of flaws. Surface of specimen is periodically heated by heat flow in form of s...
