The application of infrared thermal imager in the research of tumor photothermal therapy

The human body is a biological heat body, and the dimensions of each part are not equal. The normal temperature distribution of human body has certain stability and symmetry. If temperature changes occur somewhere in the human body, it indicates that there is a lesion in the body. The reason is that changes in blood flow and metabolism in the body of the lesion cause the distribution of temperature in the body, which may be temperature rise or decrease in temperature. The infrared thermograph shows the temperature distribution of human body and its degree of temperature distribution. The doctor observed in the analysis of the infrared thermal image and quantitative measure of temperature difference value, combined with the anatomy, pathology and clinical experience, can be diagnosed patients with and without symptoms and lesions, as well as its location, nature and degree.
Along with the development of the infrared thermal imaging technology, especially the development of refrigeration focal plane infrared array, medical infrared thermal imaging technology has become the CT, mri, B to wait after the mainstream of modern medical imaging technology and a new breakthrough, and opened up to the function of new medical imaging field. It has a wide range of clinical applications, not only for early detection, but also for tracking observation, disease diagnosis, evaluation of efficacy, and medical research.
