[0002] In recent years, cone beam computed tomography (CBCT) imaging technology has seen increasing clinical applications in veterinary medicine, such as fracture treatment, gastrointestinal obstruction, and three-phase angiography. Three-phase angiography involves rapidly injecting a contrast agent into the animal's body within seconds using an independent, external high-pressure syringe pump.

Both the first position and the second position are positions, but they are not the same position.
[0050] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if there is transmission of electrical signals or data between the connected circuits, modules, units, etc.
[0051] When used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.
[0052] In an exemplary embodiment, Figure 1 As shown, a CBCT integrated device 10 equipped with an injection pump is provided, including: a bed 100, a ray generating device 200, a detector 300, a injection pump 400 and an infusion tube 500.
[0053] The bed body 100 includes a bed board 110 and a support portion 120 . The support portion 120 is used to support the bed board 110 . A pipe groove is provided in a non-imaging area of the bed board 110 .
[0054] The ray generating device 200 is used to generate X-rays.
[0055] The detector 300 and the ray generator 200 are arranged opposite to each other, and the detector 300 is used to receive X-rays and generate CBCT data based on the X-rays. The ray generator 200 and the detector 300 scan together around the circumference of the animal to be detected to collect projection data. Specifically, Figure 1 The dotted line L in FIG is the movement trajectory of the ray generating device 200 and the detector 300 .
[0056] The injection pump 400 includes a mechanical drive device 410 and a pump body 420. The pump body 420 is arranged in a non-imaging area through the mechanical drive device 410, and the mechanical drive device 410 is used to drive the pump body 420 to rotate to a first position when it is necessary to inject drugs, and to drive the pump body 420 to rotate to a second position when it is not necessary to inject drugs; wherein, the pump body 420 is used to load drugs to be injected; the first position is a position where the needle component of the pump body 420 points to a position below the horizontal plane, and the second position is a position where the needle component of the pump body 420 points to a position above the horizontal plane.
[0057] At least part of the infusion tube 500 is fixed in the tube groove; one end of the infusion tube 500 is connected to the needle component of the pump body 420, and the other end of the infusion tube 500 is connected to the injection component. The injection component can be an animal injection needle or a heparin cap.
[0058] The tube groove can fix the infusion tube 500 , thereby preventing the infusion tube 500 from being entangled during use of the CBCT integrated device 10 equipped with the syringe pump.
[0059] The tube groove can be molded directly on the bed plate 110. Furthermore, the bed body 100 can be made of carbon fiber, and therefore, the tube groove molded on the bed body 100 can also be made of carbon fiber. The diameter of the tube groove can be larger than the diameter of the infusion tube 500 to ensure that the tube groove can accommodate the infusion tube 500. For example, the diameter of the tube groove can be 1.5 times the diameter of the infusion tube 500, taking into account both the tube groove's capacity and its fixation capabilities.
[0060] The non-imaging area of the bed board 110 includes the sidewalls and the footboard surface of the bed board 110. If the tube groove is located on the sidewall of the bed board 110 in the non-imaging area, the infusion tube 500 may fall off the sidewall due to the weight of the injected drug. Therefore, the infusion tube 500 may be secured in the tube groove using an adhesive material. The adhesive material may be transparent tape. If the tube groove is located on the footboard surface of the non-imaging area, the operator can clearly observe the flow of the injected drug, thereby ensuring the reliability of the injection.
[0061] When the injected drug is a contrast agent, the high density of the contrast agent used in phase III angiography can easily create high-density artifacts on the image, seriously interfering with image interpretation. The placement of the tube groove in the non-imaging area prevents the contrast agent in the infusion tube 500 from interfering with the image, thereby ensuring image quality.
[0062] When a drug injection is required, the pump body 420 rotates to the first position, ensuring that the drug in the pump body 420 can flow smoothly into the infusion tube 500 under the action of gravity, thereby completing the injection of the drug. Conversely, when the drug injection is not required, the pump body 420 rotates to the second position, ensuring that the drug in the pump body 420 can remain in the pump body 420 under the action of gravity and not flow into the infusion tube 500, thereby preventing the drug from leaking out of the pump body 420 and flowing into the infusion tube 500 or even into the injection component when injection is not required.
[0063] Therefore, the above-mentioned CBCT integrated device 10 equipped with an injection pump includes a bed 100, a radiation generator 200, a detector 300, an injection pump 400, and an infusion tube 500. A tube groove is provided in the non-imaging area of the bed 110 to secure the infusion tube 500, prevent the infusion tube 500 from becoming entangled, ensure normal infusion, and reduce image artifacts. Furthermore, the mechanical drive device 410 can drive the pump body 420 to rotate when a drug needs to be injected, so that the needle component of the pump body 420 points to a position below the horizontal plane to ensure the outflow of the injected drug. The mechanical drive device 410 can also drive the pump body 420 to rotate when no drug needs to be injected, so that the needle component of the pump body 420 points to a position above the horizontal plane to prevent the injected drug from flowing out of the pump body 420. Furthermore, this CBCT integrated device 10 equipped with an injection pump can directly perform image exposure after injection, thereby capturing three-phase contrast images in a timely and accurate manner and obtaining high-quality images.
[0064] In an exemplary embodiment, the tube groove is a plurality of U-shaped grooves connected end to end.
[0065] Compared to a linear tube groove, a plurality of U-shaped grooves connected end to end can accommodate a longer infusion tube 500 .
[0066] Of course, the pipe groove can also be other bending curves.
[0067] In one embodiment, the above-mentioned CBCT integrated device 10 equipped with an injection pump further includes: an anti-slip buckle.
[0068] The anti-slip buckle is set in the tube groove to increase the friction between the tube groove and the infusion tube 500, reduce the risk of the infusion tube 500 slipping out of the tube groove, and thus reduce the risk of the infusion tube 500 being entangled outside the tube groove.
[0069] In an exemplary embodiment, the aforementioned integrated CBCT device 10 equipped with an injection pump further includes: a controller.
[0070] The controller is connected to the mechanical drive device 410; the controller is used to drive the mechanical drive device 410 to drive the pump body 420 to rotate to the first position when receiving an injection instruction; and drive the mechanical drive device 410 to drive the pump body 420 to rotate to the second position when receiving an end instruction and / or an initialization instruction.
[0071] The controller can respond to instructions to complete corresponding actions, thereby realizing automatic driving of the mechanical drive device 410. Among them, the injection instruction can be understood as an instruction issued when the drug needs to be injected; the end instruction can be understood as an instruction issued when the injection is completed; and the initialization instruction can be understood as an instruction issued when the drug to be injected is temporarily no longer needed after the pump body 420 is loaded with the drug to be injected.
[0072] In an exemplary embodiment, Figure 2 As shown, the pump body 420 includes a fixed cylinder 422 , a syringe 424 and a driving motor 426 .
[0073] The fixed cylinder 422 has an accommodating space therein; the fixed cylinder 422 is provided with a mechanical driving device 410 .
[0074] Syringe 424 includes a syringe barrel 4242, a sealing piston 4244, and a push rod 4246. The sealing piston 4244 is fixedly connected to the push rod 4246. A needle assembly is provided at one end of the syringe barrel 4242, and the sealing piston 4244 is disposed at an end away from the needle assembly. The syringe 424 is partially disposed within the accommodating space, with the needle assembly exposed to the environment. The syringe 424 is used to load the medication to be injected. The push rod 4246 may be a threaded push rod. Preferably, one end of the push rod 4246 is tightly coupled to the sealing piston 4244 via a one-way lock, and the other end of the push rod 4246 is connected to the drive motor 426 via a threaded lock.
[0075] The driving motor 426 is disposed in the accommodating space and away from a side of the needle component; the driving motor 426 is connected to the controller and the push rod 4246 respectively.
[0076] The controller is also used to control the drive motor 426 to drive the push rod 4246 to move when an injection instruction is received.
[0077] Preferably, the injection cylinder 4242 is detachably connected to the fixed cylinder 422, so that the injection cylinder 4242 can be separated and removed from the fixed cylinder 422, and the drive motor 426 can be removed from the fixed cylinder 422, so as to replace the injection cylinder 4242 and repair the drive motor 426. Specifically, the detachable connection can be a connection method based on a thread lock.
[0078] When no medication is required for injection, the needle assembly of the pump body 420 is directed above the horizontal plane, positioned at a certain angle, thereby preventing leakage of the injected medication. When medication is required for injection, the mechanical drive device 410 drives the needle assembly of the pump body 420 to point below the horizontal plane, positioning it downward at a certain angle. The controller controls the drive motor 426 to drive the push rod 4246 to move, pushing the sealing piston 4244 to squeeze the injected medication, causing the injected medication to flow out of the infusion tube 500 and enter the animal's body through a specific path. After the injection is completed, the controller controls the mechanical drive device 410 to drive the needle assembly of the pump body 420 to point back above the horizontal plane, restoring the default state of the needle assembly pointing upward.
[0079] In one embodiment, Figure 2 As shown, threaded caps A may be provided at both ends of the infusion tube 500 to connect with the needle component and the injection component respectively to ensure the stability of the connection.
[0080] Preferably, the detachable connection is a connection based on a thread lock, and such a setting can prevent the infusion tube 500 from being dislodged due to pressure during high-pressure injection.
[0081] In an exemplary embodiment, Figure 1 As shown, the pump body 420 is disposed in the non-imaging area of the bed 100 through the mechanical driving device 410 .
[0082] Preferably, the pump body 420 can be connected to the bed body 100 through the mechanical driving device 410, taking into account both functionality and space.
[0083] In an exemplary embodiment, Figure 3 As shown, the mechanical driving device 410 includes a universal rotating arm 412 , a lifting column 414 and a base 416 .
[0084] One end of the universal rotating arm 412 is used to fix the pump body 420 .
[0085] One end of the lifting column 414 is rotatably connected to the other end of the universal rotating arm 412 .
[0086] One end of the base 416 away from the ground is connected to the other end of the lifting column 414 .
[0087] When the pump body 420 is fixed on the universal rotating arm 412, the staff can flexibly adjust the direction of the needle component in the pump body 420 according to actual needs, thereby meeting the needs of various working conditions.
[0088] The lifting column 414 can adjust the placement height of the pump body 420 to meet the operating needs of workers of different heights, and can also meet the standing and sitting operating needs of workers.
[0089] By moving the base 416 , the placement position of the pump body 420 can be flexibly adjusted, reducing the space requirement for the environment, thereby meeting various environmental location requirements in actual applications.
[0090] In an exemplary embodiment, the bed body 100 further includes a mechanical sliding component, which is respectively connected to the bed board 110 and the support portion 120 , so that the bed board 110 can translate relative to the support portion 120 .
[0091] The controller is also connected to the mechanical sliding component, the ray generating device 200 and the detector 300 respectively; the controller is also used to drive the mechanical sliding component to drive the bed plate 110 to perform translational movement and control the ray generating device 200 and the detector 300 to start working when receiving a scanning instruction.
[0092] A scanning command can be understood as a command issued when scanning an animal to be inspected. Upon receiving the scanning command, the controller drives the mechanical movable components to translate the bed plate 110 toward the radiation generator 200 and controls the radiation generator 200 and detector 300 to scan the circumference of the animal to be inspected, thereby collecting projection data.
[0093] In one embodiment, the support portion 120 of the bed 100 is a vertically movable column.
[0094] The height of the column can be changed to suit the actual needs of the operator.
[0095] In an exemplary embodiment, Figure 4 As shown, a method for applying a CBCT integrated device equipped with an injection pump is provided. The method is applied to the above-mentioned CBCT integrated device equipped with an injection pump, and the method includes:
[0096] S402, when it is necessary to inject medicine, the mechanical driving device is driven to rotate the pump body to a first position, where the needle component of the pump body points to a position below the horizontal plane.
[0097] S403, controlling the pump body to push out the medicine to be injected.
[0098] S404, when no medicine needs to be injected, the mechanical driving device is driven to rotate the pump body to a second position, where the needle component of the pump body points to a position above the horizontal plane.
[0099] When a drug injection is required, the mechanical drive mechanism drives the pump's needle assembly to a position below the horizontal plane, positioned downward at a certain angle. The pump is then controlled to push the drug out, causing it to flow out of the infusion tube and into the animal's body through a specific path. When a drug injection is not required, the pump's needle assembly is directed above the horizontal plane, positioned at a certain angle, to prevent the drug from leaking.
[0100] In an exemplary embodiment, when the pump body includes a drive motor, the step of controlling the pump body to push out the drug to be injected includes:
[0101] Obtain actual case data.
[0102] The bolus parameters are determined according to actual case data and based on a bolus parameter prediction model; wherein the bolus parameter prediction model is a model determined by model training based on clinical case data, or a function model determined based on a data fitting method; the bolus parameters include bolus time and bolus speed.
[0103] When an injection instruction is received, the drive motor is controlled to drive the push rod in the pump body to move according to the injection parameters.
[0104] Bolus parameters are determined based on a bolus parameter prediction model, eliminating the need for the operator to consider individual differences among the animals being tested. Specifically, when contrast agents are injected, the bolus rate and duration are determined by the bolus parameter prediction model, eliminating the need for the physician to consider individual differences between animals. This avoids the need for multiple boluses of contrast agents due to misjudgment by the physician, significantly reducing the metabolic burden and renal risks on the animal.
[0105] To better explain the complete workflow of the CBCT integrated device equipped with a syringe pump, further explanation is now provided, using a three-phase scan of an animal as an example:
[0106] When performing a three-phase scan, the doctor first inputs the actual case data into the CBCT integrated device equipped with an injection pump. Specifically, the CBCT device software paired with the CBCT integrated device equipped with an injection pump can be set to create a case in the CBCT device software, and load relevant parameters (actual case data) and initialization operations. Among them, the loaded relevant parameters include exposure parameters such as X-ray tube voltage, tube current and exposure time, and imaging parameters such as reconstruction voxels and reconstruction matrix. For example, the X-ray tube voltage used can be 110kV, the tube current can be 20mA, and the exposure time can be 10ms. The reconstructed voxels involved can be 0.5×0.5×0.5mm 3 The reconstruction matrix can be 512 × 512 × 512. The initialization operation includes placing the ray generator, detector and injection pump in place.
[0107] At the same time, the animal is anesthetized and placed in a position that is determined by the imaging site. For example, in the case of delayed renal angiography, the animal is placed in the supine position.
[0108] The bedplate is controlled to move horizontally to support the animal, the vertical height of the support structure is changed to support the animal to the designated imaging area, and a command (injection command) is issued to activate the syringe pump, allowing the contrast agent to flow from the infusion tube and enter the animal's body through the U-shaped cannula. The injection rate and injection time are determined by a bolus parameter prediction model. Preferably, the bolus parameter prediction model is trained using a deep neural network using extensive clinical experimental data. Alternatively, a functional relationship between the key variables can be established through data fitting.
[0109] After the injection is completed, a command (end command) is issued to reset the injection pump and restore it to the default state (the pump body rotates to the second position).
[0110] The optimal arterial, venous, and delayed exposure capture times are determined based on the injection time, and the radiation generator and detector are driven to scan around the animal's circumference to collect projection data. Projection data are collected at intervals, but image reconstruction is not performed.
[0111] After all projection data is collected, the components of the CBCT integrated device equipped with the syringe pump automatically reset, and then image reconstruction is performed, displaying all three-dimensional images of the three-phase angiography. Specifically, image reconstruction can be performed based on the CBCT device software program. Figure 5 As shown, Figure 5 This is the delayed imaging effect diagram of the three-phase angiography using the CBCT integrated device equipped with an injection pump. Figure 5 The kidney area can be clearly seen in the angiography without any interference from image artifacts.
[0112] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of the steps or stages in other steps or other steps. It is understandable that the various steps in different embodiments can be freely combined as needed, and the various non-contradictory schemes formed by the combination all fall within the scope of protection of this application.
