The blood is like a river in the human body, and its temperature requirements are very high. When the temperature is too low, the river will freeze; if the temperature is too high, the water will evaporate. Therefore, Chinese medicine practitioners say that "the blood is warm, but not the heat". It can be seen that the words used in the "Yellow Emperor's Internal Classic" are very precise.
Infrared thermal imaging diagnostic technology is a new imaging method. It is a subject that diagnoses diseases and studies human physiological and pathological phenomena by collecting heat radiated from the human body and processing it through computer to form a unique "hot" image of the human body. . Since the human body itself is a natural source of biological infrared radiation, it continuously emits infrared radiation energy. Under physiological conditions, the heat radiated by the human body is maintained in a balanced, stable, constant state. When the human body changes or the physiological condition changes, the whole body or local heat balance will be broken, and the infrared thermal image scanning can accurately detect any changes in heat balance in various parts of the human body.
Infrared thermal imaging technology is applied in medicine and is called thermal image. Human beings are warm-blooded animals, and the human body is a natural source of biological infrared radiation, which continuously scatters infrared radiation energy into the surrounding space. When the human body is sick or physiologically altered, the systemic or local thermal balance is disrupted or affected, and clinically manifests as an increase and decrease in tissue temperature. At present, the widely used infrared thermal imaging tests various diseases, which proves that infrared thermal imaging technology can meet the clinical needs, especially in the treatment of TCM syndrome differentiation.
Since the publication of the first thermal image of the human body by Professor Czerny on the Maine in Frankfurt in 1928, medical thermal imaging has only emerged in Germany in the early 1950s. Initially a separate infrared detector was used. Due to the development of other thermal imaging devices, such as contact thermal imaging of electronic thermometers and LC (liquid crystal) screens, infrared thermal imaging technology is integrated into medical diagnostic systems.
Medical infrared thermal imaging technology is a combination of medical technology, infrared camera technology and computer multimedia technology. It is an imaging device for recording the thermal field of human body. A person is a warm-blooded animal that can maintain a certain body temperature. From a physics point of view, the human body is a natural biological heating element that constantly radiates infrared radiation energy to the surrounding space. When the human body is sick or some physical conditions change, this systemic or local heat balance is destroyed and affected, so it is clinically expressed as an increase and decrease in tissue temperature. Therefore, we can monitor the occurrence and development of diseases by measuring the changes in body temperature, and provide a basis for clinical diagnosis. Many scholars at home and abroad also apply the characteristics of infrared thermography to health examinations.
