Double active transient thermography [PDF]
NDT and E International, 2022 This paper presents an innovative variant of the Active Transient Thermography (ATT), designated Double Active Transient Thermography (DATT), where the component inspected is excited by one heat and one cold sources. The goal is to speed up and improve the temperature contrast, namely for polymer matrix composites parts produced by Additive ...

Diabetic Plantar Foot Segmentation in Active Thermography Using a Two-Stage Adaptive Gamma Transform and a Deep Neural Network [PDF]
Sensors, 2023 Pathological conditions in diabetic feet cause surface temperature variations, which can be captured quantitatively using infrared thermography. Thermal images captured during recovery of diabetic feet after active cooling may reveal richer information ...

Excitation Source Optimisation for Active Thermography [PDF]
Proceedings, 2018 In active thermography, the use of an optimised excitation source can simplify the interpretation of measurement results. Our custom designed source, especially designed for dynamic line scanning thermography, minimises the needed excitation power and ...

Spot Weld Inspections Using Active Thermography
Applied Sciences, 2022 Spot welds have a significant part in the creation of automotive vehicles. Since the integrity of, for example, a car, is dependent on the performance of multiple welds, it is important to ensure the quality of each spot weld.

Dynamic Vascular Imaging Using Active Breast Thermography
Sensors, 2023 Mammography is considered the gold standard for breast cancer screening and diagnostic imaging; however, there is an unmet clinical need for complementary methods to detect lesions not characterized by mammography.

ACTIVE DYNAMIC THERMOGRAPHY IN MAMMOGRAPHY
TASK Quarterly, 2004 We discuss limitations of the known methods of IR imaging in diagnostics of breast cancer. In conclusion we show that the known methods, based on simple observation of external temperature distribution, are not fully effective.
