Infrared thermography (IRT) for the assessment of microvascular skin blood flow in a specialist connective tissue disease unit
Aim. To establish standardised infrared thermography (IRT) within a specialist connective tissue disease unit, assessing its utility: • for the evaluation of Raynaud’s Phenomenon (RP) in clinical rheumatology and research • for the detection of active localised scleroderma (LS) lesions in …

Regulation of surface temperature in mammals
… of 56 mammal species were measured using infrared-thermography (IRT) at ambient temperatures from $-$5 to 35 C. Not all species were available at all temperatures. All of the animals' responses were evaluated in terms of effect on heat exchange and thermoregulatory ability. The responses …

Comparative study of non-destructive testing methods of defect detection on aircraft
… In this thesis, Digital shearography and Infrared Thermography (IRT) techniques are employed to test aircraft composite materials. Background information on the techniques has been presented and the literature survey has confirmed the use of these techniques on aircraft structures. Much of …

An investigation into the use of infrared thermography as a tool to assess the physiological stress response in the horse
… the use of temperature measurement using infrared thermography (IRT) as an objective, non-invasive method to identify the physiological stress response in the horse. The primary area of investigation was the eye area within the medial posterior palpebral border of the lower eyelid and the …

Assessment of Infrared Thermography for NDE of FRP Bridge Decks
… situations. This thesis will discuss the use of Infrared Thermography (IRT) as a means of detecting debonds and voids caused by conditions encountered both in fabrication and in the field. As forced convective hot air is applied within the bridge deck, debonds between bridge deck components near …

Direct Quantitation of Heat Loss in Human Subjects Using Infrared Thermography
Infrared thermography (IRT) can be used to quantitate changes in mean surface temperature. This value is one variable used in heat loss equations which permits computation of radiant, convective, evaporative and total heat losses from subjects. The portable, non-contact, non-invasive nature of the …

Application and Evaluation of Non-Destructive Testing Methods for Buried Pipes
… Radar (PPR), Ground Penetrating Radar (GPR), and Infrared Thermography (IRT) to evaluate the detection and characterization accuracy of these technologies. Results showed that both the BCT technologies detected all three voids behind the corrugated steel pipe wall, while PPR and GPR found one of …

Long-Term Performance of Polymeric Materials in Civil Infrastructure
… this study investigated the viability of using infrared thermography (IRT) and ultrasonic testing (UT) for routine inspection. The study discovered that environmental parameters, such as temperature, wind, and humidity, can affect IRT accuracy, and that a proper heating-cooling cycle can aid in …

Investigation of skin temperature differentials in relation to estrus and ovulation in sows using a thermal infrared scanning technique
… during the periovulatory period using digital infrared thermography (IRT), which has already been successfully used as a therapeutic and diagnostic tool in various fields and species in veterinary medicine. The experimental group consisted of a total of 25 gilts and 27 multiparous sows, and a …

The use of infrared thermography and behavioural and physiological responses as early disease indicators in calves
… lying and water drinking) and physiological (infrared temperatures and respiration rate) responses which occur during the onset of neonatal calf diarrhoea (NCD), and to assess their suitability as early disease indicators. Additionally, due to an increasing trend towards providing calves with …

Assessing the impact of lameness on fertility and oestrus behaviour of dairy cattle: A comparison of oestrus detection methods with the evaluation of a modern detection method
… to evaluate a new oestrus detection technology (Infrared Thermography (IRT)). Through an online questionnaire, it was determined that 85% of respondents noticed behavioural changes associated with lameness (reduced oestrus expression, less mounting activity, increased lying times), and that lame …

Improving on quality control methods used in commercial MEA manufacturing
… control. They are automated visual inspection, infrared thermography (IRT) and x-ray fluorescence (XRF). A rig was successfully designed and built for the automated visual inspection and IRT and methods were successfully developed for the use of the 3 techniques in MEA fabrication. The results …
