Poikilothermia is a fundamental symptom of acute limb ischemia (ALI) and is known as "6Ps". Herein, we present the visualization of poikilothermia caused by ALI using handheld thermography. We believe that handheld thermography could be useful to assess poikilothermia objectively as a supplementary method to physical examination.

We theoretically and numerically analyze thermal invisibility based on the concept of scattering cancellation and mantle cloaking. We show that a small object can be made completely invisible to heat diffusion waves, by tailoring the heat conductivity of the spherical shell enclosing the object. This means that the thermal scattering from the object is suppressed, and the heat flow outside the ...

Delamination is one of the most common defects in laminate composite materials. To detect delaminations, different non-destructive test methods such as infrared thermography methods are currently widespread for non-destructive inspection, recommended for evaluating composite materials mostly in the active variant. The principle behind infrared thermography consists in highlighting the relevant ...

Thermography (infrared imaging) is a non-invasive technique applied for the detection breast cancer. We consider the problem of automatically recognition malignant breast from frontal view thermography image presented as gray scale image. This framework provides insights into several issues: breast Region of Interest (ROI) detection, extraction statistical features, extraction features based on...

Infrared thermography is used for measuring and analyzing physiological functions and pathology related to the body’s thermal homeostasis and temperature. This review provides an overview of the technological advantages of infrared imaging, with the focus on new advances in and opportunities for infrared imaging, as a reliable medical diagnostic tool. The review has four main parts. Firstly, a ...

The possibility that subclinical increased heat of the limb may be an early and reliable sign in the diagnosis of deep venous thrombosis is being investigated using thermography. Of the 35 cases studied 17 have had early deep venous thrombosis confirmed on phlebography. Of these, 16 cases have been previously diagnosed using thermography.

The ability to measure occupants’ thermal state in real time will enable major advances the control of air conditioning systems. This study proposes predicting occupant by a combination infrared thermography, computer vision, and machine learning. approach (1) uses cheek, nose, hand temperatures because they are least subject blockage hair, glasses, clothing; (2) measures distribution skin with...
