ThermEval's ACT Examination is a thermographic disease screening procedure for detecting thermal signs of coronary artery atherosclerosis, stenosis of the carotid arteries, and various thyroid dysfunctions. TAS employs sophisticated digital image processing to quantitatively and objectively assess and report the risk for development of the diseases.
The examination is based on the solid principal that humans are symmetrical, with the left and right sides in the perfect body being mirror images of each other. The thermal patterns on the bodies of healthy individuals are relatively symmetrical temperature distributions. Departure from this normal right/left thermal symmetry indicates abnormality, and the possible presence of disease. The more serious the disorder, the more pronounced are the differences in thermal symmetry. Conversely, the more pronounced the differences, the more serious might be the underlying cause.
The presence and severity of subclinical atherosclerosis or carotid stenosis is disclosed in the ACT Examination by detecting and processing subtle signs of thermal asymmetry between multiple quasi-independent vascular regions on the left and right sides of the face and neck. TAS evaluates each of twenty-five regions of the face and neck. Those regions evidencing thermal abnormality derive a score based on statistical pathological significance. The total score is translated into five classes of risk: Normal, Borderline, Equivocal, Diagnostic, and Conclusive.
Detection of signs of thyroid disorder is based on a hyperactive thyroid gland generates excessive heat, which often produces a region of elevated temperatures over the hyperactive thyroid lobe. The cause of the inflammation is unknown, but might indicate hyperthyroidism, or a more serious cause of inflammation. Similarly, a hypoactive thyroid generates less heat and manifests as a cooler region over the dysfunctional area. TAS's interpretation objectively evaluates the thermal patterns over the thyroid and reports abnormalities that suggest further clinical investigation.
