The human body is a natural source of infrared radiation, constantly radiating infrared radiation energy around. When the human body is ill, the thermal balance of the whole body or local part of the human body is destroyed, which is clinically manifested as the increase or decrease of the temperature of human tissues. Therefore, the change of human body temperature is an important index for clinical diagnosis of diseases.

Infrared thermal imager can display and record the temperature distribution in the human body, and the pathological changes of human body thermal and normal physiological state of human body thermal image comparison, judged by comparing the difference between the pathological state, compared with the conventional detection means, the infrared thermal imaging system in the process of reflect the change of body temperature and metabolism has an irreplaceable characteristics.

Medical infrared thermal imaging technology uses infrared radiation from the body's own skin, is passive, no harm to the human body. This technology has been used in clinical diagnosis in China for decades, and has been used in the diagnosis of various diseases, mainly in the following aspects:

1. Early diagnosis of breast tumor

Normally, the thermal map of both breasts in a healthy woman is symmetrical, and any breast thermal map asymmetry is often associated with cellular activity and disease, more likely to be associated with tumors. The surrounding blood vessels of malignant tumor are rich and the cells are active, and the temperature of malignant tumor is higher than normal tissue. The results showed that the tumor tissues had vigorous metabolism, rich blood supply and local radiation of heat. Therefore, using infrared thermal camera to detect breast cancer is very advantageous.

2. Screening for neurological diseases

At present, infrared thermal camera is the only method used in pain clinic department for the screening of headache, joint pain, neuralgia, shoulder, neck, waist and leg pain and other painful diseases. Is characterized by the intracranial vascular biphasic changes of vascular functional disease, neck, (arthropathy, single or multiple peripheral nerve damage, neuritis, etc., can be through the characteristics of the thermal imaging performance, reflect the pathological changes of plant nerve adjust vasomotor function changes affect the skin temperature, and thus indirectly prompt neural function, thereby indirectly infer related diseases of the nervous system, to the doctor accurate diagnosis of the disease provide powerful evidence.

3. Test for skin diseases and inflammation

When lesions and inflammation occur in the superficial tissue areas near the skin surface, the body surface temperature distribution usually changes, which can be detected in advance by thermal imager. Infrared thermal camera can be used for early warning of superficial inflammation in all parts of the body, such as rhinitis, thyroiditis, pneumonia, pharyngitis, stomatitis, gastroenteritis, etc. Advanced infrared thermal camera can also be used for burn area and depth examination, frostbite area and depth examination, skin graft treatment, etc.

4. Clinical application of Traditional Chinese medicine and acupuncture

In Traditional Chinese medicine, infrared thermal camera is used for TCM assisted dialectics, and the lesions presenting high temperature are classified as cold, Yin and deficiency. When the temperature is higher in some lesions, then to clear the heat, discharge the method to cure, when the temperature is lower, then to warm. Based on the principle of acupuncture and moxibustion, the infrared thermal imaging method can assist medical treatment, and part of the mechanism of acupuncture and moxibustion treatment can be understood from the side. Local acupuncture for some human lesions can improve, shrink or disappear. The thermal image shows that the local temperature increases significantly after acupuncture, which represents the improvement of blood circulation and the increase of local metabolic volume.

Of course, the application direction of medical infrared thermal imager is far more than the above several kinds. For clinical diagnosis application, medical thermal imager must have perfect functions to meet the medical needs.

The medical infrared thermal imager developed and produced by Yoseen Infrared is accurate in temperature measurement, with clear imaging, non-contact temperature measurement, safe and non-radiation, and is the "magnifying glass" for body hidden dangers, realizing the "visualization" of Traditional Chinese medicine.
