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...

The development and application of nondestructive testing technology for prestressed reinforced concrete structures in the field infrastructure construction were summarized this study via analysis relevant literature worldwide. detection methods, principles, instruments quality evaluation analyzed compared, based on which, acoustic emission technology, impact echo ultrasonic infrared thermograp...

Vibrothermogrphy is a promising technique that uses ultrasonic elastic waves to locally stimulate defects on solids specimens and is typically applied in the aerospace and automotive industries. This technique allows for defect selective imaging using thermal waves that are generated by ultrasound waves. The mechanism involved is frictional heating or hysteresis that turns a dynamically loaded ...

The paper presents a simplified mathematical model to describe the transient heat transfer of a radiant floor heating system. A purpose-built test room has been realized to investigate the actual thermal response of a concrete radiant floor in unsteady-state conditions. Beyond the temperature sensors needed for the standard thermal analysis of the heat transfer inside the chamber, the floor tem...

Recently, a novel approach was proposed which combines advantages of both pulse (PT) and modulated (MT) infrared thermography. In a nondestructive evaluation (NDE) perspective, the specimen is pulse-heated as in PT and the rnix offrequencies ofthe thermal waves launched into the specimen are unscrambled by perforrning the Fourier transform of the temperature time evolution over the field of vie...
