[0002] The dual-energy X-ray bone densitometer is a measuring instrument used to examine bone mass. It is an X-ray-based device for measuring the bone density of the human forearm. The X-ray penetrable plastic material is used as a mold sleeve, and a gray scale calibration value is set. The usage method of the bone module calibration device is the same as that of measuring human bone density. The X-ray contrast imaging system of the instrument converts the analog quantity of the radiation penetration rate of the bone module after irradiation into a gray scale digital quantity readable by the instrument's computer system. After comparison and calculation processing with the gray scale standard digital quantity of the bone density value stored in the instrument's computer system, information such as bone density is presented in ways such as text, charts, curves, and video images. The detection operation of the device is relatively cumbersome, and it is inconvenient to adjust the irradiation position, which affects the detection accuracy.

[0003] When the device is performing detection, it is necessary to adjust the position of the irradiation instrument according to different detection positions. The irradiation instrument is prone to shaking or deviation during movement, and the irradiation instrument is prone to damage after long-term use.
