[0002] The X-ray photography device is a medical device for general X-ray photography examination, belongs to a low-risk medical ray device of Class III, and is mainly used for imageological examination of the chest, breasts and other parts of the body. The medical X-ray photography bed is a special device used for placing the examinee and arranging the photography body position during X-ray photography examination, and is mainly divided into a fixed bed and a mobile bed.

[0003] When the existing X-ray photography bed is used for photographing patients with different heights, the examination part of the body needs to be accurately aligned with the irradiation center of the X-ray machine and the detector.

Moreover, during the X-ray examination process, even if the main ray beam is focused on the examination part, scattered rays or leakage rays may still be generated. If the head is directly irradiated, the cumulative radiation dose of these organs will be increased, and the long-term tumor risk will be increased. In addition, if the patient is displaced due to voluntary activity or involuntary tremor during the exposure process, the image will be blurred or deviated, and misdiagnosis or missed diagnosis may occur.
