[0002] X-ray technology has been widely used in veterinary diagnosis, especially in early detection and accurate diagnosis. Traditional two-dimensional X-ray equipment is widely used in veterinary clinics and animal hospitals due to its small footprint, with high space utilization. However, two-dimensional X-ray imaging has the problem of tissue overlap, multiple organs or tissues may overlap, affecting the accuracy of diagnosis, especially in complex parts such as the chest and abdomen.

[0003] To solve this problem, three-dimensional X-ray imaging technology, especially spiral CT and CBCT equipment, has gradually been applied.

[0032] an X-ray source assembly 101, a flat panel detector 109, an animal bed 103, respiratory anesthetic gas conversion joints 104a and 104b, and a control module;

[0033] The X-ray source assembly 101 and the flat panel detector 109 are oppositely arranged on a rack to constitute a basic imaging unit.

[0034] The animal bed 103 comprises rotating mechanisms 105a and 105b, which are arranged between the X-ray source assembly 101 and the flat panel detector 109.

[0035] The respiratory anesthetic gas conversion joint 104a and 104b are provided with a structure with 360-degree full rotation function;

[0036] The control module executes a preset program through a computer device, selects an adaptive scanning mode according to different animal types, and realizes two-dimensional or three-dimensional imaging.

[0037] The rotation mechanism 105a and 105b of the animal bed 103 are symmetrically arranged on both sides of the bed body, and drive the animal bed 103 to rotate around a horizontal axis to realize three-dimensional scanning; specifically, the animal bed 103 includes a pair of symmetrically arranged driving assemblies arranged on the left and right sides of the animal bed 103; the driving assembly is controlled by a servo motor, such as a stepping motor or a direct current motor, to realize 360-degree rotation of the animal bed 103 around the horizontal axis; the design of the rotation mechanism 105a and 105b ensures that the animal bed 103 can stably and accurately rotate during scanning, thereby completing three-dimensional scanning; further described, the rotation mechanism 105a and 105b are composed of a pair of synchronous driving assemblies, the driving assemblies are connected to the rotating shaft through a transmission device, such as a gear, a chain or a belt, to ensure the stability and accuracy during rotation; the structural design of the rotation mechanism 105a and 105b ensures high rotation accuracy, so that each angle of imaging can provide clear three-dimensional data; the angle control during rotation is accurately adjusted by the servo motor and the control module to meet the scanning needs of different animals; during the start of the scanning process, the control module automatically adjusts the rotation speed and angle of the rotation mechanism 105a and 105b according to the type and scanning needs of the animal, to ensure that the entire scanning area can be covered; through the rotation mechanism 105a and 105b, the animal bed 103 can smoothly rotate around the horizontal axis, avoiding the problem of tissue overlap caused by fixed position in traditional imaging systems; the rotation mechanism 105a and 105b work with the animal fixing device to ensure the stability of the animal during rotation; the animal bed 103 is provided with a fixing structure, such as Figure 2 As shown, including adjustable animal restraint belt 201 and animal restraint cover 202, and rotating bed plate 203, which can effectively prevent the animal from falling off and loosening during rotation, reduce motion artifacts and ensure imaging quality.

[0038] The invention is further configured such that the animal bed 103 has a detachable structure with a stretcher buckle interface at the bottom, allowing it to be used independently as an animal transport stretcher after being detached from the frame. Specifically, the animal bed 103 adopts a detachable structural design with a stretcher buckle interface at the bottom. This interface includes a fixing device and a release mechanism, allowing the user to easily detach the animal bed 103 from the frame without disassembling other key components. After detachment, the animal bed 103 can be used independently as an animal transport stretcher, providing sufficient support and stability to ensure the safety and comfort of the animal during transport. The stretcher buckle interface design makes the disassembly and reinstallation process quick and convenient, improving work efficiency and ease of operation.

[0039] The present invention is further configured such that the respiratory anesthetic gas conversion connectors 104a and 104b include a fixed end and a rotatable end. The fixed end is connected to an external anesthetic gas source, and the rotatable end rotates synchronously with the animal bed 103. The connectors also have an airtight structure inside. Specifically, the fixed ends of the respiratory anesthetic gas conversion connectors 104a and 104b are connected to an external anesthetic gas source via pipes to ensure a stable supply of anesthetic gas to the animal. The rotatable ends of the connectors employ high-precision bearings and an airtight structure design to ensure that the gas channel remains sealed during rotation, preventing anesthetic gas leakage.

In two-dimensional imaging mode, the beam limiter 102 is used to adjust the range of the imaging field of view; in three-dimensional imaging mode, the beam limiter 102 is used to cover the entire field of view of the flat panel detector 109. Specifically, the beam limiter 102 is installed between the X-ray source and the flat panel detector 109. When the system is in two-dimensional imaging mode, the beam limiter 102 precisely controls the range of the X-ray beam by adjusting the size of its opening, thereby limiting the imaging field of view and covering only the required portion of the scanning area. This limiting measure effectively avoids unnecessary radiation, improves imaging quality, and reduces the impact of radiation on the surrounding area. In three-dimensional imaging mode, the structure of the beam limiter 102 is adjusted to a full field of view coverage state, ensuring that the X-ray beam can cover the entire area of ​​the flat panel detector 109, thereby achieving a complete three-dimensional imaging scan. At this time, the opening of the beam limiter 102 is fully expanded to ensure the uniform distribution of the X-ray beam, maximize the integrity and accuracy of the imaging area, and meet the full field of view scanning requirements in three-dimensional imaging mode.

[0043] The system further comprises anti-collision switches 106a and 106b arranged at both ends of the bed body translation path, for preventing collision with the wall or gas barrier at both ends during long-range three-dimensional scanning; specifically, the anti-collision switches 106a and 106b are arranged at both ends of the bed body translation path, usually on both sides of the animal bed 103, to monitor whether the bed body contacts the barrier during scanning; the anti-collision switches 106a and 106b can adopt limit switches, proximity sensors or photoelectric sensors, etc., which can sense the motion state of the bed body, and when the bed body approaches both ends of the path, the sensor will detect and immediately feed back a signal to the control module, and after the control module receives the signal, it will immediately adjust the motion state of the bed body, stop or slow down the movement of the bed body, to avoid collision; in order to improve the accuracy of anti-collision, the anti-collision switches 106a and 106b are arranged to be high sensitivity, which can quickly respond when the bed body approaches the barrier, and can withstand certain external interference; the arrangement of the anti-collision switches 106a and 106b can ensure that the bed body does not collide with the wall or gas barrier at both ends during long-range three-dimensional scanning, ensuring the safety of the equipment and the animal.

[0044] The system further comprises lifting columns 107a and 107b for adjusting the distance between the animal and the detector to avoid interference with the detector during three-dimensional imaging; specifically, the lifting columns 107a and 107b are installed on the bottom of the animal bed 103 or the support structure, and can adjust the height of the bed body in the vertical direction, thereby adjusting the distance between the animal and the flat panel detector 109; the lifting columns 107a and 107b are driven by electric drive or servo motor, and the lifting speed and stroke of the lifting columns 107a and 107b are accurately controlled by the instruction of the control module, to ensure that the distance between the animal and the detector is appropriate, and to avoid that the posture or body shape of the animal interferes with the image quality of the detector during three-dimensional imaging; the adjustment range of the lifting columns 107a and 107b can be set according to the body shape of different animals and scanning requirements; in the implementation process, the sensors or encoders equipped in the lifting columns 107a and 107b can monitor the height change in real time, and feed back the signal to the control module, and the control module adjusts the height of the lifting columns 107a and 107b according to the preset program or real-time scanning requirements, to ensure the accurate docking during imaging; at the same time, the stability of the lifting columns 107a and 107b is also very important, and high-precision guide rails or support systems are usually used to ensure that they do not vibrate or deviate during lifting, to avoid affecting the stability of scanning and the quality of images.

[0045] The application further provides that the computer device comprises a memory and a processor, the memory stores a computer program, the program automatically selects an appropriate scanning mode according to the type of the animal, and processes the obtained imaging data to optimize the imaging effect; specifically, the computer program will determine the required imaging mode, such as two-dimensional or three-dimensional imaging, based on the animal's body size, species, scanning area and other parameters, and adjust the settings of the imaging device according to these parameters, including scanning angle, exposure time, scanning speed and resolution; the processor is responsible for executing the instructions in the program and processing the obtained imaging data in real time, the imaging data is transmitted to the computer device through the control module, the computer program optimizes the image data, such as noise reduction, detail enhancement, contrast adjustment, etc., to ensure that the final image quality meets the diagnostic requirements; the program may also dynamically adjust according to the real-time feedback data during the scanning process, such as imaging quality and animal position, to further optimize the imaging effect; during the operation of the system, the computer device will automatically generate the best scanning scheme according to the body size and scanning requirements of different animals, and control the working parameters of each system component to ensure that each scan can obtain accurate and high-quality image results, improve the efficiency and accuracy of diagnosis.
