[0029] Specifically, in this embodiment, the height position of the adjustment port is the same as the height position of the insertion port, and the adjustment port is located on the left side surface of the outer protective box 1, that is, the axial center line of the adjustment port is perpendicular to the axial center line of the insertion port, so that an adult can extend his hand into the shooting space through the adjustment port, and can conveniently directly adjust the palm posture and position of the measured child.

[0030] Specifically, in this embodiment, a hand-entry protective curtain channel 4 is provided on the front side of the outer protective housing 1 and on the outer cover of the access opening. A protective curtain A 5 is provided on the inner side of the hand-entry protective curtain channel 4. The opening of the hand-entry protective curtain channel 4 on the end away from the outer protective housing 1 is smaller than the opening of the hand-entry protective curtain channel 4 on the end closer to the outer protective housing 1. The provision of the hand-entry protective curtain channel 4 allows the subject to accurately pass through the access opening and into the imaging space while maintaining an outstretched arm. The hand-entry protective curtain channel 4 and the outer protective housing 1 can both be made of steel plates. In this embodiment, a magnet is provided at the junction of the hand-entry protective curtain channel 4 with the protective housing 1, and the protective curtain channel 4 is attracted to the protective housing 1 by magnetic force.

[0032] Specifically, if Figure 4As shown, in this embodiment, a vertical partition 8, a transverse partition 9, and an inner protective box 10 are provided in the inner cavity of the outer protective box 1. The vertical partition 8 is located below the transverse partition 9, and the inner protective box 10 is located above the transverse partition 9. The inner space surrounded by the vertical partition 8, the transverse partition 9, the inner protective box 10, and the inner side wall of the outer protective box 1 serves as the shooting space of the outer protective box 1. The space in the inner cavity of the outer protective box 1 other than the shooting space serves as the equipment installation space. A radiation-proof material layer is provided on the inner side wall of the outer protective box 1. A radiation-proof material layer is also provided on one side of the vertical partition 8 located in the shooting space, one side of the transverse partition 9 located in the shooting space, and the inner side of the inner protective box 10. The radiation-proof material layer is provided using existing technology, such as using lead plates. The shooting space is formed by the vertical partition 8, the horizontal partition 9, the inner protective box 10 and the inner side wall of the outer protective box 1. Since there is a layer of radiation-proof material, the shooting space can be relatively closed, effectively avoiding unnecessary radiation brought by X-rays to the person being tested.

[0033] The X-ray generating assembly includes an X-ray generator 11 and a beam-limiting lead plate 12. The X-ray generator 11 is mounted on the outside of the inner protective housing 10. The beam-limiting lead plate 12 is disposed on the top of the inner protective housing 10. The beam-limiting lead plate 12 has an X-ray aperture for the X-rays to pass through. X-rays emitted from the light-emitting end of the X-ray generator 11 pass through the X-ray aperture in the beam-limiting lead plate 12 and enter the imaging space of the outer protective housing 1. The flat-panel detector 2 is mounted on the bottom surface of the inner cavity of the outer protective housing 1. The beam-limiting lead plate 12 controls the X-ray field of view. In this embodiment, the X-ray generator 11 and the flat-panel detector 2 are commercially available products, and the arrangement of the beam-limiting lead plate 12 also adopts existing technology.

[0034] In this embodiment, the side of the vertical partition 8, located outside the imaging space, can be used to mount the equipment's control circuit board. A wiring panel 15 is also mounted on the rear side of the outer protective housing 1, saving overall space.

The outer protective housing 1 effectively protects the control circuit board, X-ray machine 11, and other components within the equipment's mounting space.

[0035] Specifically, in this embodiment, observation window 3 is located directly above the access opening, allowing a person outside the device to accurately determine the hand's posture and position within the capture space. A camera 7 is located within the capture space within the inner cavity of outer protective housing 1 and is positioned directly above observation window 3. Camera 7 is a commercially available product and is connected to the device's control circuit board.

[0036] Through the setting of camera 7, the operator of the equipment can remotely view the posture and position of the hand in the shooting space, which is basically consistent with the perspective of the person observing from the observation window 3, making it convenient for the operator of the equipment to communicate with the person outside the equipment and to make reliable adjustments to the palm of the child being measured.

[0037] Working principle:

[0038] When examining the person being examined, the person's hand is extended into the shooting space through the hand entry and exit protective curtain channel 4 and the insertion port. The camera 7 can transmit the real-time position and posture of the person's palm to the external computer display. The person being examined can also directly view the position and posture of the palm through the observation window 3 and adjust it. For young children who find it difficult to adjust their palms to the correct position and posture by themselves, other adults can extend their hands into the shooting space through the adjustment port to directly assist in adjusting the posture and position of the child's palm. After adjusting the palm position, the X-ray machine 11 emits X-rays, and the X-rays emitted by the X-ray machine 11 pass through the palm. The flat-panel detector 2 receives the X-ray signal and converts the X-ray signal into a digital signal of the image to complete the shooting. The external computer system to which the bone age meter is connected determines the bone age of the person being examined by analyzing the image.
