[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The infrared transmitter 3 is configured to transmit infrared rays for detecting bones; the infrared receiver includes a first receiver 7 that receives infrared rays emitted by the infrared transmitter 3 and transmitted through bones.

[0040] In this embodiment, the bone imaging device uses infrared rays to detect bones, which improves the problem of the existing bone imaging device causing greater radiation damage to the human body compared to the use of X-rays to detect bones. Furthermore, infrared detection technology can distinguish the absorption spectrum of bones to infrared light in a specific band, has the advantages of non-invasive and non-contact detection, and is suitable for large-scale screening.

[0041] In some embodiments, the bone imaging device further includes a carrying mechanism 5 for carrying the limb to be detected, and the carrying mechanism 5 includes a carrying platform 51 arranged opposite to the infrared emitter 3 .

[0042] In some embodiments, the distance between the infrared transmitter 3 and the carrying platform 51 is adjustable; and the infrared transmitter 3 is configured to move two-dimensionally in a plane parallel to the carrying platform 51 to adjust its position relative to the carrying platform 51. The infrared transmitter 3 can adjust its position relative to the carrying platform to adapt to different working conditions and improve the applicability of the bone imaging device. Furthermore, the infrared transmitter 3 can emit infrared rays to the limb to be detected at different orientations and different distances. This is conducive to adjusting the intensity and orientation of the infrared rays received by the infrared receiver.

[0043] like Figure 2 and 3As shown, the bone imaging device also includes a motion mechanism 1, which includes a first moving component 17. The first moving component 17 is configured to move in a first direction within a plane relative to the supporting platform 51. The infrared transmitter 3 is installed on the first moving component 17 and is configured to move in a second direction perpendicular to the first direction within a plane relative to the first moving component 17.

[0044] The motion mechanism 1 further comprises a first motor 12 for driving the first moving component 17 to move along a first direction.

[0045] In some embodiments, the motion mechanism 1 also includes a second movable component 13, which is configured to be movable along a third direction perpendicular to the plane relative to the supporting platform 51, and the first movable component 17 is installed on the second movable component 13 and is configured to move along the first direction relative to the second movable component 13.

[0046] The motion mechanism 1 further includes a second motor 11 for driving the second moving component 13 to move along a third direction.

[0047] In some embodiments, the first movable component 17 extends along the second direction, and both ends of the first movable component 17 along the second direction are respectively connected to the second movable component 13 .

[0048] In some embodiments, the second movable component 13 includes two first guide components 18 arranged in parallel and spaced apart to guide the first movable component 17 to move along the first direction. The two first guide components 18 are connected, and both ends of the first movable component 17 are movably connected to the two first guide components 18 respectively.

[0049] In some embodiments, the motion mechanism 1 further includes a second guide component 14 for guiding the second movable component 13 to move along the third direction, and a second guide component 14 is provided at both ends of each first guide component 18 .

[0050] The motion mechanism 1 also includes a support frame 15, on which the second guide members 14 are mounted, and a support block 16 is mounted below the support frame 15. The support block 16 contacts the bearing surface of the imaging device. Four second guide members 14 are arranged at the four corners of a rectangle, and two adjacent second guide members 14 are connected by an intermediate connecting rod to form a frame structure. The first guide member 18 is located between two adjacent second guide members 14, and both ends of the first guide member 18 have second guide members 14, which is conducive to making the process of the first guide member 18 moving along the third direction more stable.

[0051] like Figure 5As shown, the bone imaging device further includes a rotating mechanism 2 connecting the first movable part 17 and the infrared transmitter 3, and the rotating mechanism 2 includes a first rotating part 21 and a second rotating part 22. The first rotating part 21 is connected to the first movable part 17 and is configured to be rotatable relative to the first movable part 17, and the axis of rotation of the first rotating part 21 relative to the first movable part 17 is perpendicular to the supporting platform 51. The second rotating part 22 is connected to the first rotating part 21 to rotate with the first rotating part 21, and the second rotating part 22 is configured to be rotatable relative to the first rotating part 21, and the axis of rotation of the second rotating part 22 relative to the first rotating part 21 is parallel to the supporting platform 51, and the infrared transmitter 3 is connected to the second rotating part 22 to rotate with the second rotating part 22.

[0052] In this embodiment, the infrared emitter 3 can rotate under the drive of the rotating mechanism 2 to adjust the position of the infrared emitter 3 relative to the detected limb, which is conducive to realizing the multi-angle irradiation of the limb by the infrared emitter 3. The second rotating component 22 rotates with the first rotating component 21 and can be adjusted to various positions in the circumference of the first rotating component 21. The infrared emitter 3 rotates with the second rotating component 22 and can rotate the direction of the infrared emitter 3 to various angles in the circumference of the second rotating component 22.

[0053] See also Figure 6 In other embodiments, the rotating mechanism 2 also includes a third rotating component 23, which is connected to the second rotating component 22 to rotate with the second rotating component 22, and the third rotating component 23 is configured to be rotatable relative to the second rotating component 22. The axis of rotation of the third rotating component 23 relative to the second rotating component 22 is parallel to the supporting platform 51 and perpendicular to the rotation axis of the second rotating component 22, and the infrared transmitter 3 is connected to the third rotating component 23 to rotate with the third rotating component 23.

[0054] In some embodiments, the first infrared receiver 7 is disposed on a side of the carrying platform 51 away from the infrared transmitter 3 .

[0055] In some embodiments, an infrared reflecting component is disposed on the side of the carrying platform 51 away from the infrared transmitter 3, and the infrared receiver further includes a second infrared receiver located on the same side of the carrying platform 51 as the infrared transmitting component 3. Optionally, the infrared transmitter 3 and the second infrared receiver are integrated together.

[0056] The imaging device of this embodiment can realize two detection modes. In the transmission detection scheme, the infrared transmitter 3 is excited and the first infrared receiver 7 is received. At this time, the carrier platform 51 is switched to the transmission mode, and the optical signal can pass through and reach the first infrared receiver 7. In the reflection detection scheme, the infrared transmitter 3 and the second infrared receiver are excited and received. At this time, the carrier platform 51 is switched to the reflection mode, and the optical signal can be reflected and received by the second infrared receiver.

[0057] In some embodiments, the infrared transmitter 3 includes a housing and an infrared transmitting component disposed in the housing, and the second infrared receiver includes an infrared receiving component located in the housing.

[0058] like Figure 1 As shown, it also includes a shell 6, and the infrared transmitter 3, the infrared receiver and the supporting mechanism 5 are arranged in the shell 6.

[0059] In some embodiments, the housing 6 is provided with an inspection port for allowing the limb to be inspected to enter, and the carrying platform 51 is configured to move relative to the housing 6 in a direction perpendicular to the plane where the inspection port is located.

[0060] like Figure 4 As shown, the carrying mechanism 5 further includes a third guide member 53, which is configured to guide the carrying platform 51 to move relative to the housing 6. The carrying mechanism further includes a bracket 54 that supports the third guide member 53. In some embodiments, the third guide member 53 includes a guide rail. The bracket 54 is fixed in the housing 6, the third guide member 53 is mounted on the bracket 54, and the carrying platform 51 is mounted on the guide member 53 to move back and forth in the housing 6 to adjust the position of the carrying platform 51.

[0061] The bone imaging device also includes a camera 4 disposed in the housing 6. The camera 4 is mounted on the side wall of the housing 6 to monitor the placement of the target. The camera 4 can also measure the thickness of the detection target.

[0062] In some embodiments, the carrying mechanism 5 further includes a positioning component 52 disposed on the carrying platform 51 for positioning the limb being detected.

[0063] During the test, the test target is inserted into the front test port. Since the determination of bone diseases requires a more standardized bone image, there are certain requirements for the imaging morphology of the phalanges. Therefore, four positioning mechanisms 52 are fixed on the bearing platform 51, and the test target is laid flat on the bearing platform 51, against the four positioning mechanisms 52, so as to facilitate the positioning of the finger joints. During the adjustment process, medical staff can provide auxiliary guidance through the camera 4. After placement, through the cooperation of the three-axis moving mechanism 1 and the bearing mechanism 5, according to the single-frame or multi-frame detection requirements, the detection and positioning are carried out with the assistance of the camera 4; through the three-way rotating mechanism 2, according to the personalized detail requirements, it can be freely rotated in the xy, yz, and zx planes formed by the xyz three-axis to achieve imaging in any direction, any angle, and any distance. Furthermore, the camera 4 measures the target thickness, which can assist in adjusting the detection distance of the detection device to improve the imaging clarity.

[0064] The second motor 11 drives the second moving part 13 to move up and down along the second guide part 14 to control the vertical distance between the infrared transmitter 3 and the second infrared receiver and the detection target. The 1-2 forward and backward movement motor drives the 1-7 forward and backward movement mechanism to move forward and backward, and cooperates with the left and right movement of the three-way rotating mechanism 2 to achieve horizontal positioning of the detection target position. The three-way rotating mechanism 2 can control the infrared transmitter 3 and the second infrared receiver to rotate freely in the three planes of xy, yz, and zx, so that the infrared transmitter can be excited and imaged from any direction, angle, and distance.

[0065] Since the area of ​​the infrared image to be captured may be large, multiple groups of infrared transmitters 3 and receiving modules can be used together, mainly divided into overall detection and local key parts detection. The excitation light and photoelectric conversion element of the overall detection module can irradiate a large area of ​​bones and complete the detection at one time. However, since the detection accuracy of large-scale imaging may not be high enough, local key parts detection is provided to perform more accurate detection of key features and improve the clarity of bone imaging.

[0066] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
