Background
According to the different absorption and transmission rates of different tissues of human body to X-ray, the CT uses the precisely collimated X-ray to scan the cross section of a certain position of human body one by one, the detector receives the X-ray transmitted through the layer, the X-ray is converted into visible light, the visible light is converted into electric signal by photoelectric conversion, the electric signal is converted into digital signal by analog/digital converter, the digital signal is input into computer, the computer processes the digital signal, the cross section or stereo image of the detected position of human body can be taken, and the tiny lesion of any position in human body can be found. The CT machine has the characteristics of short scanning time, clear images and the like, and can be used for checking various diseases.
The bulb is one of the core components of the CT apparatus. The CT bulb tube is a high-vacuum cathode ray diode, a 12V power supply is used for heating a cathode filament to generate a free electron cloud set, when 40-150 kV high-voltage electricity is applied to a cathode and an anode, due to the steep increase of potential difference, electron beams in a free active state impact an anode molybdenum-based tungsten target at a high speed by a cathode to generate energy conversion, about 1% of electric energy forms X rays, the X rays are emitted from a window, and the rest of the electric energy is converted into heat energy and is cooled by a cooling system.
X-rays are short electromagnetic waves of strong penetration, the higher the voltage the stronger the penetration. X-rays attenuate when penetrating a substance, which is the physical basis for X-ray imaging. People use the principle of X-ray to make human tissue produce different attenuation ray projections, the silver bromide on the film is developed into black after being sensitized, and the silver bromide which is not sensitized is developed into transparent white after being fixed, so that black and white images are produced, namely the photographic effect. The attenuation degree of the X-ray is related to the density and the thickness of an irradiated object, the level difference of black and white shadows displayed on the imaging indicates the difference of tissue density in a human body, and the higher the density is, the whiter the image is; conversely, the darker the image. Of course, the density of the tissue in the human body changes when the tissue is diseased, and the black and white images captured change accordingly, which is the principle of image diagnosis.

Step 406: the energy output switch 25, upon receiving a close command from the control module 24, closes so that: the power supply signal output by the recovered energy storage module 23 reaches the X-ray beam generator energy storage module 34 via the closed energy output switch 25.
Step 407: the control module 24 sends an off command to the energy output switch 25 when detecting that the energy stored by the energy storage module 34 of the X-ray beam generator of the CT machine is changed from not meeting the energy required by the current operation of the X-ray beam generator to meeting the energy.
