本发明所述的红外线热扫描系统， 其工作原理： 喉道组织内血管的血流， 动脉血温度 较高， 静脉血温度较低， 两者存在某种热交换机制， 两者都向外辐射不同波长的红外线， 喉道及其周边粘膜组织自身的温度不但受到血管内血流的影响，也受自身的新陈代谢的影 响，所以组织内发生异变的部分的温度会由于血管丰富与否和新陈代谢的活跃程度的不同 而表现出差异性，比如癌变或者炎症等，对外辐射的红外线的波长也各不相同。研究表明， 血液中的成分 （血清、 血浆、 血红蛋白、 白蛋白、 红细胞、 淋巴细胞、 血小板）在光谱中 对红外光的吸收最低，意味着血液除了对外辐射红外线外，还对周围组织的红外线的吸收 影响很小， 红外线热扫描系统的精度小于等于 0.05度， 空间分辨能力至少达到 0.8mrad， 红外线热扫描探头在喉中作近距离进行扫描， 得到精细精确的红外图像。 The infrared thermal scanning system of the present invention, its working principle: blood flow of blood vessels in the throat tissue, arterial blood temperature Higher, venous blood temperature is lower, there is some kind of heat exchange system, both of which radiate different wavelengths of infrared rays. The temperature of the throat and its surrounding mucosal tissue is not only affected by blood flow in the blood vessels, but also by The influence of its own metabolism, so the temperature of the part of the tissue that is abnormal in the tissue may be different due to the difference in the degree of blood vessel enrichment or metabolism, such as cancer or inflammation, and the wavelength of infrared rays radiated from the outside is also different. . 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 infrared thermal scanning system has an accuracy of less than or equal to 0.05 degrees and a spatial resolution of at least 0.8 mrad. The infrared thermal scanning probe scans at a close distance in the throat to obtain a fine and precise infrared image.

The signal is converted into an electrical signal, and after pre-processing (such as amplification, filtering, etc.), the preamplifier and the main amplifier are amplified to a certain level and then enter the infrared heat treatment system host. At the same time, the signal input to the host also has a synchronization signal, a reference black signal, and the like. The data obtained by multi-plane continuous cross-cut scanning is transmitted to the infrared thermal scanning system host for image processing, and output to the infrared system monitor to clearly display the stereoscopic blood vessel static image of the throat. The doctor can analyze the image and find the throat and peripheral mucosa. Abnormalities such as abnormal blood vessels, sparse vascular abnormalities, or areas with vascular loss, provide doctors with immediate diagnosis.
