[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Combination Figures 1 to 5 As shown, the bone imaging device of this embodiment includes an infrared emitter 3 and an infrared receiver. The infrared emitter 3 is configured to emit infrared light to detect bones; the infrared receiver includes a first receiver 7 that receives the infrared light emitted by the infrared emitter 3 and transmits it through the bones.
[0040] In this embodiment, the bone imaging device uses infrared light to detect bones, which, compared to X-ray detection, improves upon the problem of significant radiation damage to the human body caused by existing bone imaging devices. Furthermore, infrared detection technology can distinguish the absorption spectrum of infrared light by bone in specific wavelengths, offering the advantages of being non-invasive and non-contact, making it suitable for large-scale screening.
[0041] In some embodiments, the skeletal imaging device further includes a support mechanism 5 for supporting the limb to be detected, the support mechanism 5 including a support platform 51 disposed opposite to the infrared emitter 3.
[0042] In some embodiments, the distance between the infrared emitter 3 and the support platform 51 is adjustable; and the infrared emitter 3 is configured to move in two dimensions in a plane parallel to the support platform 51 to adjust its position relative to the support platform 51. The infrared emitter 3 can adjust its position relative to the support platform to adapt to different working conditions and improve the applicability of the skeletal imaging device. Furthermore, the infrared emitter 3 can emit infrared rays to the limb to be detected at different orientations and distances. This facilitates adjusting the intensity and orientation of the infrared rays received by the infrared receiver.
[0043] like Figure 2 and 3As shown, the skeletal imaging device also includes a motion mechanism 1, which includes a first moving part 17 configured to move in a first direction relative to the support platform 51 in a plane. An infrared emitter 3 is mounted on the first moving part 17 and configured to move in a second direction perpendicular to the first direction relative to the first moving part 17 in a plane.
[0044] The motion mechanism 1 also includes a first motor 12 for driving the first moving part 17 to move along a first direction.
[0045] In some embodiments, the motion mechanism 1 further includes a second moving component 13, which is configured to be movable relative to the support platform 51 in a third direction perpendicular to the plane, and a first moving component 17 is mounted on the second moving component 13 and configured to move relative to the second moving component 13 in a first direction.
[0046] The motion mechanism 1 also includes a second motor 11 for driving the second moving part 13 to move in a third direction.
[0047] In some embodiments, the first moving part 17 extends along a second direction, and the two ends of the first moving part 17 along the second direction are respectively connected to the second moving part 13.
[0048] In some embodiments, the second moving component 13 includes two first guide components 18 arranged in parallel and spaced apart to guide the first moving component 17 to move along a first direction. The two first guide components 18 are connected to each other, and the two ends of the first moving 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 member 14 that guides the second moving member 13 to move along a third direction, and the second guide member 14 is provided at both ends of each first guide member 18.
[0050] The motion mechanism 1 also includes a support frame 15, on which the second guide components 14 are mounted. A support block 16 is also installed below the support frame 15. The support block 16 contacts the bearing surface that supports the imaging device. Four second guide components 14 are arranged at the four corners of a rectangle, with adjacent second guide components 14 connected by a central connecting rod to form a frame structure. A first guide component 18 is located between two adjacent second guide components 14, with second guide components 14 at both ends, which helps to make the movement of the first guide component 18 in a third direction more stable.
[0051] like Figure 5As shown, the bone imaging device also includes a rotating mechanism 2 connecting the first moving part 17 and the infrared emitter 3. 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 moving part 17 and is configured to rotate relative to the first moving part 17. The axis of rotation of the first rotating part 21 relative to the first moving part 17 is perpendicular to the support platform 51. The second rotating part 22 is connected to the first rotating part 21 to rotate with the first rotating part 21. The second rotating part 22 is configured to rotate relative to the first rotating part 21. The axis of rotation of the second rotating part 22 relative to the first rotating part 21 is parallel to the support platform 51. The infrared emitter 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 limb being detected, which is beneficial for achieving 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 the orientation of the infrared emitter 3 can be rotated to various angles in the circumference of the second rotating component 22.
[0053] See Figure 6 In some other embodiments, the rotating mechanism 2 further includes a third rotating component 23 connected to the second rotating component 22 to rotate with the second rotating component 22. 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 support platform 51 and perpendicular to the axis of rotation of the second rotating component 22. The infrared emitter 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 located on the side of the carrying platform 51 away from the infrared transmitter 3.
[0055] In some embodiments, an infrared reflector is provided on the side of the support platform 51 away from the infrared emitter 3, and the infrared receiver further includes a second infrared receiver located on the same side of the support platform 51 as the infrared emitter 3. Optionally, the infrared emitter 3 and the second infrared receiver are integrated together.
[0056] The imaging device in this embodiment can implement two detection methods. In the transmission detection scheme, the infrared emitter 3 excites the light, and the first infrared receiver 7 receives it. At this time, the support platform 51 switches to transmission mode, and the light signal can pass through and reach the first infrared receiver 7. In the reflection detection scheme, the infrared emitter 3 and the second infrared receiver excite and receive the light. At this time, the support platform 51 switches to reflection mode, which can reflect the light signal and receive it by the second infrared receiver.
[0057] In some embodiments, the infrared transmitter 3 includes a housing and an infrared emitting component disposed within the housing, and the second infrared receiver includes an infrared receiving component located within the housing.
[0058] like Figure 1 As shown, it also includes a housing 6, with an infrared transmitter 3, an infrared receiver, and a support mechanism 5 housed inside the housing 6.
[0059] In some embodiments, the housing 6 is provided with a detection port that allows the limb to be inspected to enter, and the support platform 51 is configured to move relative to the housing 6 in a direction perpendicular to the plane where the detection port is located.
[0060] like Figure 4 As shown, the support mechanism 5 further includes a third guide member 53 configured to guide the support platform 51 relative to the housing 6. The support mechanism also includes a bracket 54 supporting the third guide member 53. In some embodiments, the third guide member 53 includes a guide rail. The bracket 54 is fixed within the housing 6, the third guide member 53 is mounted on the bracket 54, and the support platform 51 is mounted on the guide member 53 to move back and forth within the housing 6 to adjust the position of the support platform 51.
[0061] The skeletal imaging device also includes a camera 4 housed within the housing 6. The camera 4 is mounted on the side wall of the housing 6 and is used to monitor the target's placement. The camera 4 can also measure the thickness of the target being detected.
[0062] In some embodiments, the support mechanism 5 further includes a positioning component 52 disposed on the support platform 51 for positioning the limb being detected.
[0063] During the detection process, the target is inserted into the front detection port. Since skeletal disease diagnosis requires relatively standardized skeletal images, the imaging morphology of the finger bones has certain requirements. Therefore, four positioning mechanisms 52 are fixed on the support platform 51. The target is laid flat on the support platform 51, abutting against the four positioning mechanisms 52 to facilitate the positioning of the finger joints. During adjustment, medical personnel can provide assistance and guidance through the camera 4. After placement, the three-axis moving mechanism 1 and the support mechanism 5 work together to perform detection and positioning with the assistance of the camera 4, according to single-frame or multi-frame detection requirements. The three-directional rotation mechanism 2 allows free rotation in the xy, yz, and zx planes formed by the xyz axes, according to individual detail requirements, achieving imaging in any direction, at any angle, and at any distance. Furthermore, the camera 4 measures the target thickness, which can assist in adjusting the detection distance of the detection device to improve image clarity.
[0064] The second motor 11 drives the second moving part 13 to move up and down along the second guide part 14, controlling the vertical distance between the infrared emitter 3 and the second infrared receiver and the target being detected. The 1-2 forward and backward motion motors drive the 1-7 forward and backward motion mechanism to move forward and backward, coordinating with the left and right movement of the three-direction rotation mechanism 2 to achieve horizontal positioning of the target. The three-direction rotation mechanism 2 can control the infrared emitter 3 and the second infrared receiver to rotate freely in the xy, yz, and zx planes, enabling the infrared emitter to excite and image from any direction, angle, and distance.
[0065] Since the area to be captured in the infrared image may be large, multiple sets of infrared emitters and receiver modules can be used together, mainly divided into overall detection and local key area detection. The excitation light and photoelectric conversion element of the overall detection module can radiate a large area of bone, completing the detection in one go. However, since the detection accuracy of large-area imaging may not be high enough, local key area detection is included to perform more precise 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 within the protection scope of the present invention.
