Both of them radiate different wavelengths of infrared rays, and the temperature of the colon wall and its surrounding tissues is not only the temperature. Under the influence of blood flow in the blood vessels, it is also affected by its own metabolism. Therefore, the temperature of the part of the colon wall and its surrounding tissues will be different due to the richness of blood vessels and the degree of metabolic activity. The wavelength of infrared rays is also different. For colonic inflammation or tumors, the temperature is significantly higher than normal due to its active metabolism. Studies have shown that blood components (serum, plasma, hemoglobin, albumin, red blood cells, lymphocytes, platelets) have the lowest absorption of infrared light in the spectrum, meaning that in addition to external radiation, the blood also has infrared rays to the surrounding tissue. The absorption effect is very small, the accuracy of the infrared system is less than or equal to 0.05 degrees, and the spatial resolution is at least 0.8 mrad.

At the same time, the signal input to the host also has a synchronization signal, a reference black body signal, and the like. After the infrared thermal scanning probe is started, the micro-motor is driven to extend a certain distance from the tip end of the colonoscope, and is rotated by the micro-motor to perform circular scanning on the colon wall, and the data obtained by multi-plane continuous cross-cutting scanning is transmitted to the infrared ray. The main body of the thermal scanning processing system performs image processing and outputs it to the infrared thermal scanning system monitor to clearly display the stereoscopic image of the colonic blood vessels. Through image analysis, the doctor can find that the blood vessels in the colon wall and its surrounding tissues are abnormally rich and the blood vessels are abnormally sparse. Or there are abnormal conditions such as vascular missing areas, providing doctors with immediate diagnosis basis.
