Description

Technical Field

[0001] This utility model relates to the field of scanning equipment technology, specifically to a desktop CT scanning device. Background Technology

[0002] Desktop CT scanners are miniaturized CT scanning systems that use X-ray beams to scan objects. A detector receives the X-rays passing through the object and converts them into electrical signals, which are then processed by a computer to generate cross-sectional or three-dimensional images of the object. This technology can clearly display the internal structure of an object without damaging it. Desktop CT scanners are commonly used to scan anesthetized animals, isolated tissues, and industrial components, playing a crucial role in drug development, materials analysis, and non-destructive testing.

[0003] Existing desktop CT scanning devices typically use a fixed X-ray source and detector, with a rotating stage between them. The rotating stage is used to acquire projection data from hundreds to thousands of angles, which are then reconstructed by a computer to obtain high-resolution CT images.

[0004] However, because the rotating stage can only rotate in a single circle, the vertical scanning field of view of desktop CT scanners is limited by the vertical length of the detector, generally making it narrow and unable to scan long objects completely in one go. In particular, when the vertical length of the detector is narrow, desktop CT scanners can only scan a short segment (or cross-section) of the object. The object to be scanned needs to be divided into multiple small segments, scanned multiple times, and then the CT images are stitched together to obtain a scanned image of the entire object. Although this partially solves the problem of scanning objects, the operation is cumbersome, and the stitched images generally have misalignment and distortion, which seriously reduces the accuracy and reliability of CT images. Utility Model Content

[0005] In view of this, the present invention provides a desktop CT scanning device to solve the problem that existing desktop CT scanning devices cannot completely scan long objects in one go.

[0006] This utility model provides a desktop CT scanning device, comprising:

[0007] A stage, wherein the object to be scanned is placed on the stage;

[0008] A drive mechanism, connected to the platform, is used to drive the platform to rotate;

[0009] A radiation emission module is disposed on one side of the stage, and the radiation emission module includes a radiation source;

[0010] A radiation detection module is located on the other side of the stage. The radiation detection module includes a detector, which is arranged opposite to the radiation source and is used to receive radiation emitted by the radiation source.

[0011] At least two lifting modules are respectively connected to both ends of the platform, and are used to drive both ends of the platform to lift synchronously while the driving mechanism drives the platform to rotate.

[0012] Beneficial effects: By setting up a drive mechanism and a lifting module, the stage is rotated by the drive mechanism while the lifting module moves the stage up and down. This allows the stage to move the object to be scanned in a vertical spiral motion during scanning, thus achieving a spiral scan of the object in the vertical direction to meet the requirement of scanning long objects in one go. At the same time, since the lifting modules are connected to both ends of the stage, the lifting modules at both ends can move the two ends of the stage up and down synchronously. The lifting modules can also provide strong support for the stage, improve the stability of the stage, ensure scanning accuracy, and improve the quality of CT images.

[0013] In one optional implementation, the lifting module includes:

[0014] First frame;

[0015] A lifting mechanism is connected to the platform, and the lifting mechanism drives the platform to move up and down relative to the first frame.

[0016] In one alternative implementation, the desktop CT scanning device includes:

[0017] The first connecting frame is fixedly connected to the lifting mechanism at both ends. The first connecting frame is perpendicular to the lifting mechanism and is perpendicular to the radiation emission direction of the radiation source. The first connecting frame is provided with the platform.

[0018] Beneficial effects: By setting up a first connecting frame, the lifting mechanisms at both ends are fixedly connected. The lifting mechanisms can drive the first connecting frame and thus the platform to move up and down. The first connecting frame is perpendicularly connected to the lifting mechanism, so that the first connecting frame and the lifting modules at both ends together form a gantry structure. Since the platform is set on the first connecting frame, the lifting modules at both ends can provide strong support for the first connecting frame, so that the first connecting frame has a large load-bearing capacity. Even for long and heavy objects to be scanned, the stability of the overall structure can be guaranteed.

[0019] In one alternative embodiment, the platform is provided in the middle of the first connecting frame.

[0020] Beneficial effect: By setting a platform in the middle of the first connecting frame, the platform can be subjected to more stable forces, thus improving stability.

[0021] In one alternative embodiment, the size of the first connecting frame is larger than the size of the platform along the extension length direction of the first connecting frame.

[0022] And / or, the desktop CT scanning device includes a second connecting frame, the two ends of which are fixedly connected to the bottom of the first frame (6).

[0023] Beneficial effects: By setting up a second connecting frame, the overall integrity of the lifting module is improved, which facilitates subsequent positioning, installation and adjustment operations.

[0024] In one alternative implementation, the lifting mechanism is a linear slide.

[0025] Beneficial effects: By setting the lifting mechanism as a linear slide, compared with the lead screw or electric cylinder structure in related technologies, there will be no left and right swaying, and the platform will not wobble, thus further ensuring the stability of the overall structure.

[0026] In one alternative implementation, the desktop CT scanning device includes:

[0027] A base on which the ray emitting module, the ray detection module, and the lifting module are fixedly connected.

[0028] Beneficial effects: By setting up a base, it is easy to set up the X-ray emission module, X-ray detection module and lifting module as a whole structure. At the same time, it provides a support platform for the X-ray emission module, X-ray detection module and lifting module. When in use, the modules can be integrated into a whole and used directly without the need for reassembly, saving assembly steps.

[0029] In one optional implementation, the ray emitting module includes:

[0030] The second frame is fixedly connected to the base, and the radiation source is provided on the second frame.

[0031] Beneficial effects: By setting the X-ray emission module to include a second frame, it is easier to fix and connect it to the base, and it is also easier to set up the X-ray source. This makes the arrangement of each structure more compact and also makes the overall size of the desktop CT scanning device smaller.

[0032] In one optional implementation, the ray detection module includes:

[0033] The third frame is fixedly connected to the base, and the detector is mounted on the third frame.

[0034] Beneficial effects: By setting the X-ray detection module to include a third frame, it is easier to fix and connect it to the base, and it is also easier to set up the detector. This makes the arrangement of each structure more compact and also makes the overall size of the desktop CT scanning device smaller.

[0035] In one alternative implementation, the desktop CT scanning device includes:

[0036] The controller, connected to the drive mechanism and the lifting module, is used to control the rotation of the platform while simultaneously controlling the synchronous lifting of both ends of the platform.

[0037] Beneficial effects: By setting up a controller, it is easy to automatically control the rotation of the stage while simultaneously controlling the synchronous lifting and lowering of both ends of the stage, which improves the overall intelligence of the desktop CT scanning device and enhances the user experience.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] Desktop and gantry CT scanners are both commonly used imaging devices. Gantry CT scanners are larger, with the X-ray source and detector rotating continuously in a circular motion, while the scanning bed moves horizontally to transport the patient. These two components work together to achieve a helical scan of the patient. Gantry CT scanners use a helical scanning method, enabling long-distance scanning. However, desktop CT scanners are smaller and cannot accommodate the complex mechanical transmission mechanisms of gantry CT scanners to achieve a complete scan of long objects in a single operation.

[0048] Desktop CT scanning devices in related technologies typically employ a fixed X-ray source and detector, with a rotating stage positioned between them. The rotating stage enables the acquisition of projection data from hundreds to thousands of angles, which is then reconstructed by a computer to obtain high-resolution CT images.

[0049] However, because the rotating stage can only rotate in a single circle, the vertical scanning field of view of desktop CT scanners is limited by the vertical length of the detector, generally making it narrow and unable to scan long objects completely in one go. In particular, when the detector is narrow, desktop CT scanners can only scan a short segment (or cross-section) of the object. The object to be scanned needs to be divided into multiple small segments, scanned multiple times, and then the CT images are stitched together to obtain a scanned image of the entire object. Although this can partially solve the problem of scanning long objects, the operation is cumbersome, and the stitched images generally have misalignment and distortion, which seriously reduces the accuracy and reliability of CT images.

[0050] Furthermore, when the rotating stage of the related technology achieves lifting and lowering, the bottom is usually fixed to the lifting platform. When the object is large or heavy, the object may tilt, causing the rotating stage to no longer be horizontal, which further affects the scanning accuracy of the desktop CT scanning device and reduces the quality of CT images.

[0051] To address the aforementioned technical problems, this application proposes a desktop CT scanning device.

[0052] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0053] According to an embodiment of the present invention, a desktop CT scanning device is provided, comprising:

[0054] Stage 10, on which the object to be scanned is placed;

[0055] The drive mechanism 15 is connected to the stage 10 and is used to drive the stage 10 to rotate.

[0056] X-ray emission module 1 is located on one side of stage 10, and X-ray emission module 1 includes X-ray source 2;

[0057] The X-ray detection module 11 is located on the other side of the stage 10. The X-ray detection module 11 includes a detector 12, which is arranged opposite to the X-ray source 2 and is used to receive the X-rays emitted by the X-ray source 2.

[0058] At least two lifting modules are connected to both ends of the platform 10, respectively, and are used to drive both ends of the platform 10 to lift synchronously while the driving mechanism 15 drives the platform 10 to rotate.

[0059] By setting up a drive mechanism 15 and a lifting module, the drive mechanism 15 drives the stage 10 to rotate while the lifting module drives the stage 10 to rise and fall. This allows the stage 10 to drive the object to be scanned to make a vertical spiral motion during scanning, thereby realizing a vertical spiral scan of the object to be scanned to meet the requirement of a complete scan of long objects in one go. At the same time, since the lifting modules are connected to both ends of the stage 10, the lifting modules at both ends can drive the two ends of the stage 10 to rise and fall synchronously. The lifting modules can also provide strong support for the stage 10, improve the stability of the stage 10, ensure scanning accuracy, and improve the quality of CT images.

[0060] In this embodiment, the radiation source 2 emits X-rays. Of course, in actual use, other radiation sources can be set as needed, and no further restrictions are imposed here.

[0061] In this embodiment, the stage 10, the drive mechanism 15, and the lifting module together form the motion module 5 of the desktop CT scanning device.

[0062] The drive mechanism 15 is specifically a motor, connected to the stage 10, which drives the stage 10 to rotate, such as... Figure 5 As shown. As an alternative implementation, the drive mechanism 15 can also be located in other positions, as long as it can drive the stage 10 to rotate.

[0063] like Figure 3As shown, the drive mechanism 15 and the stage 10 are integrated into a single unit, forming an electric rotary table. The stage 10 has a mounting cavity for placing the object to be scanned. Alternatively, in actual setup, the object to be scanned can be directly fixed to the stage 10, but double-sided tape is required to firmly adhere the object to the stage 10, or screws can be used to tighten the object to the stage 10.

[0064] like Figure 2 As shown, this embodiment has two lifting modules, one for each end of the platform 10. The lifting modules drive the platform 10 to move up and down. Figure 4 As shown. As an alternative implementation, more lifting modules can be provided, respectively located at both ends of the platform 10. Specifically, the lifting modules can be evenly distributed at both ends of the platform 10 to better ensure the stability of the lifting of the platform 10.

[0065] Each lifting module in this embodiment includes:

[0066] First frame 6;

[0067] The lifting mechanism is connected to the platform 10, and the lifting mechanism drives the platform 10 to move up and down relative to the first frame 6.

[0068] Depend on Figure 2 It can be seen that a first frame 6 and a first lifting mechanism are respectively provided at both ends of the platform 10.

[0069] like Figure 3 As shown, the desktop CT scanning device includes:

[0070] The first connecting frame 9 is fixedly connected to the lifting mechanism at both ends, and a platform 10 is provided on the first connecting frame 9.

[0071] As an alternative implementation, the desktop CT scanning device may not include the first connecting frame 9, but the first frame 6 may be directly fixed to both ends of the stage 10.

[0072] Specifically, the size of the first connecting frame 9 is larger than the size of the stage 10, so as to expand the size of the stage 10 for placing the object to be scanned and improve the applicability of the desktop CT scanning device.

[0073] like Figure 3As shown, along the length of the first connecting frame 9, the size of the first connecting frame 9 is larger than the size of the platform 10, which facilitates the connection between the first connecting frame 9 and the first frame 6. Along the width of the first connecting frame 9, the size of the first connecting frame 9 matches the size of the platform 10. As an alternative implementation, the size of the first connecting frame 9 may also be larger than the size of the platform 10 in both the length and width directions.

[0074] Specifically, the first connecting frame 9 is perpendicularly connected to the lifting mechanism and the first frame 6. By setting the first connecting frame 9, the lifting mechanisms at both ends are fixedly connected. The lifting mechanisms can drive the first connecting frame 9 and thus drive the platform 10 to move up and down. The first connecting frame 9 is perpendicularly connected to the lifting mechanism, so that the first connecting frame 9 and the lifting modules at both ends together form a gantry structure. Since the platform 10 is set on the first connecting frame 9, the lifting modules at both ends can provide strong support for the first connecting frame 9, so that the first connecting frame 9 has a large load-bearing capacity. Even for long and heavy objects to be scanned, the stability of the overall structure can be guaranteed.

[0075] Depend on Figure 2 It can be seen that the first frame 6 extends vertically and the first connecting frame 9 is connected between the two lifting modules.

[0076] The desktop CT scanner includes a second connecting frame 16, with both ends of the second connecting frame 16 fixedly connected to the bottom of the first frame 6. This improves the overall integrity of the lifting module and facilitates subsequent positioning, assembly, and adjustment operations. As an alternative implementation, the desktop CT scanner may not include the second connecting frame 16.

[0077] In this embodiment, a platform 10 is provided in the middle of the first connecting frame 9. By providing the platform 10 in the middle of the first connecting frame 9, the force on the platform 10 can be more stable, thus improving stability. As an alternative implementation, the platform 10 can also be provided in other positions of the first connecting frame 9, such as near the middle.

[0078] In this embodiment, the lifting mechanism is a linear slide. By setting the lifting mechanism as a linear slide, compared to the lead screw or electric cylinder structure in related technologies, there will be no left-right swaying, and the platform 10 will not wobble, further ensuring the stability of the overall structure. Of course, in other embodiments, the lifting mechanism can also be a linear motor, or a structure in which a motor drives a gear and rack, or other mechanisms that can perform lifting functions; no further restrictions are imposed here.

[0079] Specifically, there are two linear slides, namely a first linear slide 7 and a second linear slide 8, and the slides of the first linear slide 7 and the second linear slide 8 are fixedly connected to both ends of the first connecting frame 9.

[0080] The motors of the first linear slide 7 and the second linear slide 8 of the gantry structure are symmetrically distributed and the load is evenly distributed. Even when a large object to be scanned is placed and the center of gravity of the stage 10 may shift, the synchronicity of lifting and lowering can still be maintained to prevent tilting or vibration and ensure dynamic balance during the movement.

[0081] like Figure 2 As shown, the desktop CT scanning device includes:

[0082] The base 14 is fixedly connected to the X-ray emitting module 1, the X-ray detection module 11 and the lifting module.

[0083] By setting the base 14, it is easy to set the X-ray emission module 1, X-ray detection module 11 and lifting module into an integrated structure. At the same time, it provides a support platform for the X-ray emission module 1, X-ray detection module 11 and lifting module. When in use, the modules can be integrated into a whole and used directly without the need for reassembly, thus saving assembly steps.

[0084] As an alternative implementation, the desktop CT scanning device may not include the base 14, but instead the X-ray emission module 1, the X-ray detection module 11, and the lifting module may be directly fixed to the desktop.

[0085] Specifically, the X-ray emitting module 1, the X-ray detection module 11, and the lifting module are fixedly connected to the base 14 by bolts. As an alternative implementation, the X-ray emitting module 1, the X-ray detection module 11, and the lifting module can also be connected to the base 14 by other fixing methods, such as screw connection or snap-fit ​​connection, etc., without much limitation here.

[0086] like Figure 2 As shown, the ray emitting module 1 includes:

[0087] The second frame 4 is fixedly connected to the base 14, and the second frame 4 is equipped with a radiation source 2.

[0088] By configuring the X-ray emission module 1 to include the second frame 4, it is easier to fix and connect it to the base 14, and it is also easier to set up the X-ray source 2. This makes the arrangement of each structure more compact and also makes the overall size of the desktop CT scanning device smaller.

[0089] like Figure 2As shown, the X-ray emission module 1 in this embodiment includes an inverter 3, which is located on one side of the second frame 4 and connected to the X-ray source 2. Alternatively, the X-ray emission module 1 may not include the inverter 3.

[0090] Similar to the ray emitting module 1, the ray detection module 11 includes:

[0091] The third frame 13 is fixedly connected to the base 14, and the third frame 13 is equipped with a detector 12.

[0092] By configuring the X-ray detection module 11 to include a third frame 13, it is easier to fix and connect it to the base 14, and it is also easier to set up the detector 12. This makes the arrangement of the various structures more compact and also makes the overall size of the desktop CT scanning device smaller.

[0093] The second frame 4 and the third frame 13 are both set vertically. The radiation source and the detector 12 are respectively set near the top of the second frame 4 and the third frame 13 to ensure that the radiation source and the detector 12 can be set to correspond to the object to be scanned, so as to ensure the scanning effect.

[0094] The desktop CT scanning device in this embodiment includes:

[0095] The controller, connected to the drive mechanism 15 and the lifting module, is used to control the rotation of the platform 10 and to control the synchronous lifting of both ends of the platform 10.

[0096] By setting up a controller, it is easy to automatically control the rotation of the stage 10 while simultaneously controlling the synchronous lifting and lowering of both ends of the stage 10, which improves the overall intelligence of the desktop CT scanning device and enhances the user experience.

[0097] As an alternative implementation, the desktop CT scanning device may not include a separate controller, but instead the lifting mechanisms at both ends of the stage 10 may be set to the same mechanism to ensure that the number of steps during lifting is the same.

[0098] Simultaneously, the controller is connected to the drive mechanism 15 to control the rotation and synchronous, uniform motion of the stage 10. The motors of the first linear slide 7 and the second linear slide 8 are the same model and use the same controller to ensure the synchronicity of the lifting and lowering of the two linear slides. The motor that drives the stage 10 to rotate also uses the same controller, so that the stage 10 can achieve synchronous rotation and lifting motion, realizing helical scanning in a continuous and uniform manner to acquire projection data in three-dimensional space, thereby efficiently reconstructing the internal structure of the object.

[0099] The desktop CT scanning device in this embodiment operates as follows:

[0100] Place the object to be scanned on the stage 10;

[0101] Operate the two linear slides, adjust the object to be scanned to an appropriate height and then stop it. At this time, one end of the object to be scanned is in the CT scan field of view.

[0102] Set the exposure parameters for X-ray source 2 and the acquisition parameters for detector 12. At this time, both are in a waiting scan state.

[0103] At the same time, the X-ray source 2 is exposed, the stage 10 and the linear slide move at a constant speed. At this time, the rotation angle feedback signal of the stage 10 triggers the detector 12 to collect the data, and the X-ray source 2 exhibits a vertical spiral motion relative to the object being scanned.

[0104] After the object to be scanned completes the CT scan from one end to the other, the stage 10 stops rotating, the linear slide stops moving, the X-ray source 2 stops exposing, and the detector 12 stops acquiring data. The detector 12 acquires projection data and reconstructs it into a CT image by computer.

[0105] This completes the CT scan of the object to be scanned.

[0106] The desktop CT scanning device in this embodiment rotates the stage 10 and uses a lifting mechanism to provide lifting and lowering, which together simulates the effect of spiral CT. At the same time, a miniaturized gantry structure with lifting and rotation functions is set up. The gantry structure is compact and symmetrically arranged and fixed perpendicular to the ray direction. The linear slides at both ends are symmetrically distributed on both sides, bridging the stage 10. The height range of the stage 10 is large, which can adapt to objects of different sizes to be scanned.

[0107] The desktop CT scanning device in this embodiment, through the setting of the gantry structure, can achieve high-precision synchronization, strong resistance to off-center load, large load adaptability and long stroke compatibility in helical scanning. This allows the desktop CT scanning device to be small in size while still being able to achieve helical scanning like the gantry-type CT scanning device.

[0108] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
