What does the red color in the CT image represent?

Thermal scanning imaging is also called thermal CT. The system "receives" the thermal radiation in human cell metabolism by collecting various infrared rays generated by human cell tissues, and then inputs them into a computer for analysis and processing, and displays the state of human thermal radiation with different colors. "Different parts of the human body and different organs have different temperatures, but they all have normal values. For example, varicose veins of lower limbs can also have physical reactions. The higher the temperature of the protruding blood vessel, the greater the thermal radiation of this part. "

The temperature of all parts of normal human body is normal, and the image displayed on the computer screen is yellow-green. If it is high, it will turn red; if it is low, it will turn dark green. In the process of changing from normal to abnormal, different cells in the human body release different amounts of heat, that is, infrared rays with different wavelengths and amplitudes are released, and the thermal radiation of normal cells and abnormal cells is also different. By comparing the thermal radiation images produced by normal metabolism of healthy cells with those produced by abnormal structures, we can judge the degree of human body, so as to find the lesions earlier and prevent them.
