[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1-Figure 3 As shown, the dual-energy bone densitometer has an additional filtering device, which includes two slide rails 3 and an aluminum plate 5. Specifically, the slide rail 3 is made of aluminum, and the slide rail 3 adopts a long and short structure, that is, the front and rear slide rails have different structures, and the rear slide rail is slightly longer than the front slide rail, which is convenient for installation and positioning; the slide rail 3 is connected to the bracket mounting plate 2, and the aluminum plate 5 is horizontally detachably slidably connected between the slide rails 3. The bracket mounting plate 2 is also provided with a limiting member that can limit the aluminum plate 5 at the slide rail 3. Specifically, the limiting member is a screw, and the screw is threadedly connected to the bracket mounting plate 2; the screw is a hand screw 6; the hand screw 6 is used to fix the aluminum plate 5 for easy disassembly.

[0019] A positioning member for assisting in positioning the aluminum plate 5 is also provided at the slide rail 3; specifically, the positioning member is a spring sheet 4; the overall structure utilizes the spring sheet 4 to self-press the aluminum plate 5, so that the aluminum plate 5 and the slide rail 3 are relatively fixed, which is convenient and reliable; of course, in practice, similar structures such as magnetic suction type or pressure plate fixed type used to fix the aluminum plate 5 can achieve the same purpose.

[0020] The bracket mounting plate 2 is also connected to the bracket 1, and the rays are emitted from the high-pressure bulb on the upper part of the bracket 1, and are emitted to the flat-panel detector through the square opening of the horn-shaped bracket 1; the additional filtering device is composed of a slide rail 3, a spring 4, an aluminum plate 5 and a hand screw 6. The spring 4 is installed on the slide rail 3, and the aluminum plate 5 can be automatically pressed after the aluminum plate 5 is inserted; the slide rail 3 adopts a long and short structure, which is convenient for positioning during installation; after the aluminum plate 5 is installed in place, it is fixed with hand screws 6 to prevent it from falling during transportation and causing damage to the flat-panel detector; the device does not need to disassemble the chassis, and the additional filtering structure device can be installed on the outside of the machine through the detection port, which is convenient, labor-saving, safe and reliable; the overall slide groove structure is used, and the aluminum plate 5 can be installed for children to use, and the aluminum plate 5 can also be removed for adults to use.

[0021] That is, the additional filtering device is a slide groove structure. A pure aluminum plate is added between the radiation source and the flat plate to reduce the X-ray dose. The structure uses a slide groove structure, and the slide rail 3 is self-tightened using a spring 4; it can be quickly replaced without disassembling the chassis, which is convenient and reliable.

[0022] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
