Infrared imaging technology has certain advantages in detecting vascular lesions, especially the blood supply and functional status of limb blood vessels. The temperature of the body is determined by the state of blood circulation. When the blood vessels become diseased, the blood supply will be blocked and the skin temperature will decrease. , Raynaud's disease and scleroderma have important diagnostic value.

 

Due to the increase of local blood flow of arterial and venous hemangioma, the skin temperature will increase, and the thermal image of patients with varicose veins of the calf will show a unique cord. For thrombophlebitis, vascular stenosis and mechanical compression caused by various factors The diagnosis of blood circulation disorders and thermal imaging has certain significance.

 

The thermal image of Raynaud's disease shows that the peripheral temperature of fingers and toes is significantly lower than the skin temperature of normal extremities. The thermal image is very helpful for the disease and the progress of treatment. Although the temperature difference of scleroderma changes, the boundary is unclear, showing a gradual transition image, which can be used as a differential point for Raynaud's disease. Foreign institutions have used infrared imaging technology to carry out clinical diagnostic research on Raynaud's phenomenon and scleroderma, and have achieved some results.

 

Medical infrared imaging technology is a new type of medical technology, which belongs to the scope of functional imaging. This technology is combined with CTMIB superstructure imaging, which can not only understand the patient's tissue structure, but also understand the functional state of the tissue. The combination of functional imaging is the ideal modern imaging. It enables early detection of many lesions, a more comprehensive understanding of disease laws, and a more accurate diagnosis of the nature of the disease. The existing medical infrared imaging technology can qualitatively diagnose the internal lesions of the human body through the infrared thermal image of the temperature distribution on the surface of the human body, but cannot determine the location and size of the internal lesions of the human body, and cannot accurately locate the lesions. In addition, due to the complexity of the human body and the limitations of current infrared imaging cognition, it brings certain difficulties to diagnosis. By studying biological heat transfer and its medical applications, people can establish a new and accurate human body heat transfer model to evaluate the infrared images of the human body in different thermal environments, and realize the quantitative diagnosis of early diseased cells and abnormal temperature inside the human body.
