[0002] X-ray detection systems have achieved high-resolution, low-dose, and multimodal in vivo and ex vivo imaging in animal research, and are widely used in orthopedics, oncology, metabolic diseases, and drug development. However, existing X-ray detection systems for small animal in vivo or ex vivo tissue detection lack automatic filter adjustment mechanisms, resulting in high signal noise interference. Furthermore, these systems lack a detector jitter axis, making them prone to image artifacts caused by inconsistent responses of different detector pixels to X-rays of varying energies. Finally, they lack sample height adjustment capabilities, making it difficult to quickly reposition samples to the center of rotation when sample sizes vary significantly. Summary of the Invention

[0029] like Figures 1-8 An X-ray detection system is shown, comprising a fixed assembly, a rotating assembly 7, a translational assembly 6, a sample chamber 24, an X-ray assembly, and an intelligent control module 3. The fixed assembly includes a fixed plate 4 with a first through hole at its center. The rotating assembly 7 is connected to one side of the fixed plate 4 and includes a turntable 5 rotatably connected to the fixed plate 4 and a rotation drive connected between the fixed plate 4 and the turntable 5. The rotation drive is adapted to drive the turntable 5 to rotate, and the turntable 5 has a second through hole at its center, concentric with the first through hole. The translational assembly 6 is located on the other side of the fixed plate 4 and includes an X-axis translational assembly 22 and a Y-axis translational assembly 23 connected to the X-axis translational assembly 22. The X-axis translational assembly 22 is adapted to drive the Y-axis translational assembly 23 to move along the X-axis. The chamber 24 is connected to the Y-axis translation component 23 and passes through the first through hole and the second through hole. The Y-axis translation component 23 is adapted to drive the sample chamber 24 to move along the Y-axis. The X-ray component is connected to the side of the turntable 5 away from the fixed plate 4 through the Z-axis drive component. It includes a moving platform 27 connected to the drive end of the Z-axis drive component, an X-ray source 17 and a flat panel detector 18 connected to opposite ends of the moving platform 27 along the Z-axis, an automatic filter adjustment component connected to the X-ray source 17, and a jitter component connected to the flat panel detector 18. The X-ray source 17 and the flat panel detector 18 are located on opposite sides of the second through hole. The jitter component is adapted to drive the flat panel detector 18 to reciprocate along the Y-axis. The intelligent control module 3 is electrically connected to the rotation component 7, the translation component 6, and the X-ray component.

[0030] This X-ray detection system can drive the sample chamber 24, connected to the Y-axis translation component 23, to translate along the X-axis via the X-axis translation component 22. This allows for rapid adjustment of the sample to the center of the second through-hole of the turntable 5 when there are significant differences in sample size. The Y-axis translation component 23 can also drive the sample chamber 24 to translate along the Y-axis height direction, thus enabling adjustment of the sample chamber 24 in the height direction and achieving rapid and flexible adjustment of the sample position. A dithering component is provided, which drives the flat panel detector 18 to reciprocate along the Y-axis, thereby eliminating image artifacts during imaging and improving diagnostic accuracy. Through the automatic filter adjustment component, in conjunction with the intelligent control module 3, the filter parameters can be automatically adjusted according to the characteristics of the sample to be detected, thereby effectively reducing image artifacts caused by X-ray scattering, hardening effects, etc., to achieve the purpose of denoising, attenuating interference, or enhancing the target signal.

[0031] In this embodiment, as Figure 1 As shown, it also includes a main protective shell 1 covering the periphery of the fixed component and the rotating component 7, and a movable structural protective shell covering the periphery of the translation component 6; one end of the movable structural protective shell can pass through the first through hole and the second through hole, and the movable structural protective shell is adapted to translate along the X-axis direction. With this configuration, the X-ray detection system can be fully protected by the main protective shell 1 and the movable structural protective shell; the translatable setting of the movable structural protective shell allows it to be pushed and pulled along the X-axis direction, thereby opening or closing the translation component 6, which facilitates the operator in placing the test sample.

[0032] In this embodiment, as Figure 5 , Figure 7 As shown, the automatic filter adjustment assembly includes an X-axis adjustment assembly 29 connected to a filter holder 25. The filter holder 25 has multiple filter stations 21, each of which can be detachably mounted with a filter. The X-axis adjustment assembly 29 is adapted to drive the filter holder 25 to translate relative to the X-ray source 17 along the X-axis. This configuration allows filters of the required material and thickness to be installed at the stations 21 as needed. By driving the filter holder 25 carrying the corresponding material and thickness along the X-axis via the X-axis adjustment assembly 29, the filter at the required station 21 can be automatically adjusted to the position of the X-ray source 17 during actual operation, effectively reducing image artifacts caused by X-ray scattering and hardening effects, thereby achieving the purpose of denoising, attenuating interference, or enhancing the target signal.

[0033] Specifically, such as Figure 5 , Figure 6As shown, the X-ray source 17 includes a fixed substrate 26 and an X-ray generating device mounted on the fixed substrate 26. The fixed substrate 26 has a ray aperture for X-rays to pass through. The X-axis adjustment assembly 29 is adapted to drive the filter holder 25 to reciprocate along the X-axis on the fixed substrate 26. With this configuration, the required filter on the filter holder 25 can be adjusted to the position corresponding to the ray aperture, thereby effectively reducing image artifacts caused by X-ray scattering, hardening effect, etc.

[0034] In this embodiment, as Figure 5 , Figure 6 As shown, an X-ray source 17 is located on the inner wall of one end of the moving platform 27, and a flat panel detector 18 is located on the inner wall of the other end of the moving platform 27. The X-ray source 17 is adapted to emit X-rays toward the flat panel detector 18. The jitter assembly includes a Y-axis driver 30 and a jitter shaft 19 connected to the driving end of the Y-axis driver 30. The flat panel detector 18 is connected to the jitter shaft 19, and the Y-axis driver 30 is adapted to drive the jitter shaft 19 to move along the Y-axis. With this configuration, the Y-axis driver 30 can drive the jitter shaft 19 to reciprocate along the Y-axis, thereby causing the flat panel detector 18 to translate left and right along the Y-axis in a direction perpendicular to the rotation center axis. Image artifacts caused by inconsistent responses of detector pixels to X-rays of different energies are eliminated during the scanning process by homogenizing the response characteristics of each pixel of the flat panel detector 18.

[0035] In this embodiment, as Figure 4 As shown, the rotary drive component is located between the fixed plate 4 and the turntable 5, including a rotary driver fixedly mounted on the fixed plate 4, a drive gear 13 fixedly mounted on the outer periphery of the first through hole on the fixed plate 4, and a driven gear fixedly mounted on the outer periphery of the second through hole on the turntable 5. The drive gear 13 is connected to the drive shaft of the rotary driver, and the drive gear 13 meshes with the driven gear. The rotary driver is electrically connected to the intelligent control module 3. With this configuration, the drive gear 13 can be driven to rotate by a drive motor, thereby driving the driven gear to rotate, and thus causing the turntable 5 to rotate. By electrically connecting the rotary driver to the intelligent control module, the rotation mode of the turntable 5 can be adjusted and controlled, such as continuous rotation or stop-rotation.

[0036] Specifically, such as Figure 4 As shown, a rotary bearing 14 is installed on the inner wall of the first through hole. A driven gear is fixedly connected to the rotary bearing 14. Multiple locking adjustment components 15 are arranged circumferentially on the bearing seat of the rotary bearing 14. The locking adjustment components 15 are electrically connected to the intelligent control module 3. This arrangement allows adjustment of the position of the rotary bearing 14 relative to the second through hole. Adjustments are made to correct eccentric movement of the rotary bearing 14 during long-term operation or due to other factors, thereby preventing image blurring and data distortion.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, a fixed inner ring 10 located on the outer periphery of the first through hole is fixed on the side of the fixed plate 4 away from the turntable 5. A rotating cable chain 8 is mounted on the fixed inner ring 10. A rotating inner ring 9 is connected to the side of the rotating cable chain 8 near the first through hole. A fixed outer ring 11 fixed to the fixed plate 4 is provided on the side of the rotating cable chain 8 away from the first through hole. A rotating outer ring 12 connected to the rotating inner ring 9 is provided on the side of the rotating cable chain 8 away from the fixed plate 4. The rotating inner ring 9 is fixedly connected to the rotating bearing 14. With this configuration, the cable of the rotating component 7 can be placed inside the rotating cable chain 8. The rotating inner ring 9 and the rotating outer ring 12 will rotate with the rotating cable chain 8, thus ensuring the rotation of the rotating cable chain 8 when the driven driven gear rotates and the rotating inner ring 9 rotates. At the same time, the rotating inner ring 9, the rotating outer ring 12, the fixed inner ring 10, and the fixed outer ring 11 are respectively installed around the rotating cable chain 8, which can limit the rotation of the rotating cable chain 8 and eliminate the risk of cable entanglement.

One end of the sample compartment 24 is connected to the driving end of the lifting actuator, and the other end faces the fixed plate 4 and the turntable 5, and passes through the first through hole and the second through hole.

[0039] In this embodiment, the sample chamber 24 is a carbon fiber sample chamber 24. The carbon fiber sample chamber 24 has high rigidity and low density, which can prevent the sample chamber 24 from bending flexibly when carrying animal samples, and the material itself has no adverse effect on the imaging effect.

[0040] In this embodiment, as Figure 5 , Figure 6 As shown, the Z-axis drive assembly is a Z-axis driver 28 fixed to the side of the turntable 5 away from the fixed plate 4, and the moving platform 27 is connected to the drive rod of the Z-axis driver 28 via a moving shaft 16. This configuration allows adjustment of the distance between the sample center and the focal point of the X-ray source, thereby adjusting the imaging magnification ratio.

[0041] In summary, this X-ray detection system can drive the sample chamber 24, connected to the Y-axis translation component 23, to translate along the X-axis via the X-axis translation component 22. This allows for rapid adjustment of the sample to the center of the second through-hole of the turntable 5 when there are significant differences in sample size. The Y-axis translation component 23 can also drive the sample chamber 24 to translate along the Y-axis height direction, thereby enabling height adjustment of the sample chamber 24 and achieving rapid and flexible adjustment of the sample position. A dithering component is provided, which drives the flat panel detector 18 to reciprocate along the X-axis, thereby eliminating image artifacts during imaging and improving diagnostic accuracy. The automatic filter adjustment component, in conjunction with the intelligent control module 3, can automatically adjust the filtering parameters according to the characteristics of the sample to be detected, thereby effectively reducing image artifacts caused by X-ray scattering, hardening effects, etc., to achieve the purpose of denoising, attenuating interference, or enhancing the target signal.
