The advantages of infrared thermogram
1. Infrared thermography system passively accepts the body's own radiation and the formation of thermal images, in the process of ingesting thermal images, the human body does not accept the role of x-rays, ultrasound, electromagnetic waves, this diagnostic method is harmless to the human body can be used for all types of patients, including pregnant women, fetuses, can be used as often as you like. After the nuclear leak in Russia, the current trend to replace x-ray with infrared imager.
2. Non-contact measurement, the patient does not have any pain, the inspection method is simple and rapid, especially for outpatient.
3. One can observe a number of organs and even the whole body, can be used as an exploratory examination, and then further focus on observation or other ancillary checks. It is especially suitable for health examination.
4. Sensitive response, high degree of high resolution (temperature resolution of 0.05 ° C, spatial resolution of 0.8mrad)
5. High-definition color images: intuitive image with rich software processing capabilities, easy to analyze and diagnose, that is, the results of the investigation without delay in diagnosis and treatment.
6. Information storage, easy to review and compare.
As with any diagnostic imaging, each has its own advantages and disadvantages, there is a complementary, corrective issues, clinicians must provide an accurate history, signs, laboratory tests and other diagnostic imaging information, to exclude a variety of interfering factors, comprehensive consideration in order to make a more realistic diagnosis.
Medical thermography in the limb circulation of the six major advantages:
1. Measurement of skin temperature: skin thermometer and other methods can only be observed to test the local temperature, infrared thermography can not only observe the entire limb, and even the temperature of the whole body, but also can be designed to observe the temperature of a certain point on a comprehensive and focused on the study of the blood circulation to provide a favorable condition.
2. Sensitive and timely response: Measurement with a skin thermometer generally takes 1 to 3 minutes to produce results. But with thermal imaging camera, the temperature distribution image and data can be displayed instantly and sensitively.
3. High degree: It can reflect the temperature change of 0.05℃～0.1℃, so it can be considered to represent the actual temperature of the limb and blood circulation.
4. Continuous dynamic observation: the temperature at different times can be compared and analyzed. The temperature of the body surface changes with the change of the environment inside and outside the body, and the infrared thermogram can observe its dynamic change continuously, and can be repeated and analyzed through the recorder video. Thus, the law of blood circulation change can be fully observed. This is not solved by other methods. After statistical processing, the recorded images of different time, different conditions and different parts can be called out at one time for comparative analysis.
5. There is no need to touch the testing limb and the monitoring can be observed from a close distance.
6. Wide range of applications, clinical value: microsurgery before and after the observation and postoperative near and distant follow-up; thoracic outlet syndrome diagnosis and metallurgical observation; burns depth judgment; detection of the location and scope of the tumor; vascular diseases (such as thrombotic occlusive vasculitis, Raynaud's disease, etc.) diagnosis and evaluation of the efficacy of arthritis, diagnosis, lesion site and range; drug The efficacy of observation, such as vasodilator drugs, can understand the drug effect strength, duration of action, etc..
Disadvantages of thermal imaging device
1. Deep tissue and too obese people are more difficult to observe.
2. It is not yet possible to directly observe the kidneys and heart (currently used in the diagnosis of coronary heart disease).
3. At present, the domestic machine can only be standing or sitting position examination (the new has solved the problem of recumbent examination).
4. More interference. This is not necessarily a disadvantage, you can try to eliminate interference.
