Over the past 15 years, thermography has proven to be a simple, quick and reliable tool for the initial diagnosis of varicose veins.
It also provides reliable information, e.g. about inflammation, during follow-up treatment after vein surgery. Presentation of typical cases and the correlation between thermographic and pathological morphology (ultrasound).
The evaluation of vascular access in patients with chronic kidney disease undergoing hemodialysis requires accurate and reliable diagnostic techniques capable of delineating superficial venous anatomy, hemodynamic alterations, and the anatomical characteristics of arteriovenous fistulas (AVFs), while minimizing invasiveness and patient-related risks. In this context, clinical infrared...
Introduction:
Thermal heating of the skin using infrared lasers has been a valuable tool in pain research for multiple decades. Recently we have developed a closed-loop thermography-controlled system which allows accurate temperature control during moving laser stimulation. Using this setup the thermal energy transduction is no longer limited to transversally across the skin, but the...
Several diseases, including rheumatoid arthritis and cancer, are associated with localized increases in tissue temperature. This characteristic suggests that thermal imaging could be exploited for diagnostic and monitoring purposes, which led to the development of the field of medical thermography. However, when a localized hot-spot is situated more than ~15 mm beneath the skin and its...
Background and Aim: Thermal imaging is widely used to assess skin temperature. However, interpretation often relies on absolute values or qualitive patterns that provide limited insight into spatial thermoregulatory organization. Palm-to-finger thermal gradients (PFG) capture temperature distribution of the hand which reflects vascular tone and peripheral thermoregulation in response to a...
This paper explores the use of infrared thermography to analyze body heat distribution patterns in cyclists, to evaluate its potential contribution to professional bike fitting. Seven participants completed a standardized 15-minute cycling exercise, during and after which thermographic images were captured. The goal was to detect temperature asymmetries or irregularities that may indicate...
Alzheimer's disease (AD) is a progressive neurological disorder marked by memory deterioration and cognitive loss, impacting millions globally. Although AD is predominantly regarded as a brain disorder, increasing evidence indicates considerable peripheral modifications, especially within the microcirculatory system. In fact, research has shown that people with AD have platelet dysfunction and...
While not yet a common practice in standard medicine, infrared imaging is emerging as a promising non-invasive tool to support diagnostics, offering functional and physiological insights beyond the capabilities of conventional imaging techniques. By capturing subtle variations in surface and sub-surface thermal patterns, IR imaging provides real-time visualization of hemodynamic changes linked...
Flap surgery, which is widely applied in plastic and reconstructive surgery, involves the transfer of tissue from a donor site to a recipient site while preserving its intrinsic vascular supply. This technique is particularly indicated for the reconstruction of complex anatomical structures, such as the mandible or breast, as well as for the restoration of tissue defects resulting from trauma...
Introduction: Chronic itch is a clinically significant condition for which effective treatments remain limited. Experimentally induced itch using histamine and cowhage provide a controlled and reproducible way to study the mechanisms of itch, helping identify and test new therapeutic targets. However, histamine and cowhage differ in several characteristics, including their ability to elicit...
Introduction During the COVID-19 pandemic, infrared thermography (IRT) was widely used to estimate deep body temperature for workplace screening. However, we previously highlighted major limitations of predicting core temperature from skin temperature (Mekjavic & Tipton, 2020), demonstrating substantial elevations in skin temperature during moderate work in 40 °C conditions with minimal...
Breast infrared thermography is a non-invasive imaging technique capable of capturing superficial temperature distributions associated with variations in metabolic and vascular activity, offering potential support for early breast cancer screening. However, variations in acquisition conditions, patient morphology, and temperature ranges across sessions introduce significant inconsistencies in...
Active infrared thermography (IRT) offers a non-invasive route to detect and characterise
cutaneous lesions by measuring transient surface temperature responses following controlled
cooling. This thesis presents an end-to-end investigation combining physics-based
simulation, thermogram creation, algorithmic feature extraction, machine learning and
prototype instrumentation to assess the...
Carpal Tunnel Syndrome (CTS) is one of the most common peripheral entrapment neuropathies, resulting from compression of the median nerve within the carpal tunnel at the wrist. This condition is frequently associated with pain, reduced grip strength, and impaired fine motor control of the hand. Early diagnosis of CTS remains challenging, as conventional clinical and electrophysiological...
Introduction. The increasing demands of human space missions require non-invasive and autonomous health-monitoring technologies suitable for extreme environments. Quantitative infrared thermography (QIRT) is a promising tool for space medicine, providing contactless, real-time assessment of skin temperature and physiologically relevant information related to microcirculation, inflammation,...
The usage of infrared thermal imaging (IRT) for breast cancer (BC) diagnosis has been its first medical application, but its feasibility is still a debatable question. It is aim of this research study conducted in a cancer hospital to relate the thermal findings with the information retrieved from other medical imaging modalities. In a study involving 29 already diagnosed with other imaging...
Atherosclerotic disease of the carotid artery is a chronic pathological condition characterized by the progressive accumulation of lipid-rich plaques within the arterial wall, resulting in structural remodeling, altered hemodynamic conditions, and luminal narrowing, thereby posing a high risk of ischemic stroke. In this context, early identification of carotid stenosis is crucial to enable...
