Technical Field

[0001] The present application relates to the field of imaging technology, and in particular to a desktop translational X-ray fluoroscopy system. Background Art

[0002] X-ray fluoroscopy technology is widely used in medical imaging, security inspection and other fields. Traditional X-ray fluoroscopy equipment is usually bulky, expensive, and requires professional operation. With the development of science and technology, portable X-ray fluoroscopy equipment has gradually become a market demand. However, existing portable devices still have certain shortcomings in terms of image quality, ease of operation and data transmission efficiency. Therefore, the development of an X-ray fluoroscopy system that combines portability, high-quality images and efficient data transmission has become an important direction of current technological development.

[0003] At present, most portable X-ray fluoroscopy devices on the market use fixed X-ray emitters, which cannot achieve translational scanning, thus limiting the image quality within the fluoroscopy range. In addition, existing devices mostly rely on wired connections for data transmission, which limits the use scenarios and convenience of the devices. Therefore, there is an urgent need for a desktop translational X-ray fluoroscopy system to solve the above problems. Summary of the invention

[0004] In order to improve the quality of fluoroscopic image generation and reduce usage limitations, the present application provides a desktop translational X-ray fluoroscopy system.

[0005] The present application provides a desktop translational X-ray fluoroscopy system, comprising: An X-ray emitter, used to emit an X-ray beam to penetrate an object to be fluoroscopically viewed; An X-ray receiver, used for receiving X-rays passing through the fluoroscopic object and generating a fluoroscopic image; A guide rail driven by a stepper motor is used to fix and control the X-ray transmitter and the X-ray receiver to move synchronously on a two-dimensional plane; A rechargeable battery for providing power; A mobile terminal that establishes connection with an X-ray transmitter, an X-ray receiver and a stepper motor through wireless technology is designed with an X-ray fluoroscopy application interface, which includes: a first mobile operation interface; used to generate a first mobile instruction according to a user's trigger operation on the designed first mobile operation interface, convert the first mobile instruction into a pulse signal and send it to the stepper motor, so that the stepper motor controls the rotation angle and step length according to the pulse signal; and also used to receive and process fluoroscopic images, and generate result fluoroscopic images through a reconstruction algorithm.

[0006] By adopting the above scheme, a translational X-ray transmitter design is adopted, and through the movement of the X-axis and Y-axis guide rails, a comprehensive scan of the object to be fluoroscopic is achieved, thereby improving the coverage and clarity of the fluoroscopic image; a mobile terminal X-ray fluoroscopy application interface design is adopted, so that the stepper motor can drive the guide rail according to the user's fluoroscopic needs to control the synchronous movement of the X-ray transmitter and the X-ray receiver; wireless transmission technology is adopted to realize real-time fluoroscopic image data transmission between the X-ray receiver and the mobile terminal, thereby improving data transmission efficiency and convenience, while reducing the limitations of the use of the X-ray fluoroscopy equipment.

[0007] Preferably, it also includes: A position feedback device, used to collect the position information of the X-ray emitter in real time and feed it back to the mobile terminal; The mobile terminal establishes a connection with the position feedback device through wireless technology, and is also used to receive feedback position information in real time; compares the position movement information corresponding to the first movement instruction with the feedback position information received before and after the X-ray emitter is moved according to the first movement instruction, and generates a position compensation instruction based on the comparison result to control the stepper motor to continue driving the guide rail.

[0008] By adopting the above solution, considering that there will be errors when using a stepper motor to drive the track to control the movement of the X-ray emitter, a position feedback device is used to feed back the real-time position of the X-ray emitter to the mobile terminal, and a position compensation operation is performed to achieve closed-loop control and precise position control.

[0009] Preferably, the mobile terminal is also used to obtain the position movement information corresponding to the first movement instruction after issuing a preset number of position compensation instructions, and if there is still an error in the comparison result between the position movement information corresponding to the first movement instruction and the feedback position information received before and after the movement of the X-ray emitter is completed according to the first movement instruction and the preset number of position compensation instructions, and the existing error is greater than the preset error, then a prompt message indicating that the first movement instruction cannot be executed is generated accordingly.

[0010] By adopting the above solution, taking into account that the movement instruction issued by the user may exceed the movement range, resulting in the inability to meet the movement instruction issued by the user after moving to the edge of the guide rail, the movement information of the position corresponding to the movement instruction issued by the user that cannot be reached after multiple compensations is used as the judgment standard, and a prompt message is given that the corresponding movement instruction cannot be executed.

[0011] Preferably, the mobile terminal is also used to record historical prompt information of the first movement instruction that cannot be executed, count and analyze the position movement information corresponding to the historical prompt information of the first movement instruction that cannot be executed, and form a position movement information range for the position movement information corresponding to the historical prompt information of the first movement instruction that cannot be executed with an appearance frequency greater than a preset frequency; determine whether the position movement information corresponding to the new first movement instruction triggered by the user on the first movement operation interface is within the position movement information range, and if so, generate a prompt information that the first movement instruction may not be executed and display it on the first movement operation interface; after the first movement instruction is continued to be executed according to the user triggering the first operation interface, the generated first movement instruction is converted into a pulse signal and sent to the stepper motor.

[0012] By adopting the above solution, the inexecutable movement instructions generated by the user history can be recorded and statistically analyzed, so as to guide the user to avoid generating inexecutable movement instructions as much as possible.

[0013] Preferably, the X-ray fluoroscopy instrument application interface further includes: a fluoroscopy mode selection interface, and each fluoroscopy mode existing in the interface sets preset fluoroscopy parameters for a preset type of fluoroscopy object; The mobile terminal is also used to trigger the generation of perspective parameter adjustment instructions according to the perspective mode selected by the user in the perspective mode selection interface, and convert the generated perspective parameter adjustment instructions into electrical signals and send them to the X-ray transmitter and the X-ray receiver, so that the X-ray transmitter adjusts the X-ray emission intensity accordingly, and the X-ray receiver adjusts the receiving parameters accordingly.

[0014] By adopting the above scheme, different perspective mode selection interfaces are set for different types of perspective objects, so that users can select corresponding perspective modes according to perspective requirements to adjust X-ray emission intensity and X-ray receiving parameters, thereby improving the quality of the generated perspective images.

[0015] The X-ray instrument application interface also includes: a generation result feedback interface; The mobile terminal is also used to generate a regeneration result operation instruction according to the user triggering on the result feedback interface, re-process and reconstruct the received perspective image according to the regeneration result operation instruction, regenerate the result perspective image and save the result perspective image generated each time.

[0016] By adopting the above scheme, considering that the resultant perspective image generated by the initial image processing and the iterative re-algorithm does not meet the user's requirements for the perspective image, a user feedback interface is set and the image processing and reconstruction are performed accordingly, thereby generating a perspective image that the user is more satisfied with.

[0017] Preferably, it also includes: A micro camera device, used to collect image data of the object being viewed and send it to the mobile terminal; The X-ray instrument application interface also includes: a second mobile operation interface; The mobile terminal that establishes a connection with the micro camera device is also used to analyze and identify the contours and key points of the received image data of the perspective object when a trigger instruction is triggered by a second mobile operation interface designed by the user, automatically plan the movement route according to the identified contours and key points, and correspondingly generate continuous second movement instructions and convert the second movement instructions into pulse signals and send them to the stepper motor; and the mobile terminal does not support the simultaneous generation of the first movement instruction and the second movement instruction.

[0018] By adopting the above scheme, in addition to the user automatically moving the X-ray emitter to meet the perspective requirements, an automatic movement route can also be designed and continuous movement instructions can be generated accordingly to achieve global perspective of the object being perspectived.

[0019] Preferably, the X-ray instrument application interface also supports preview and editing of result perspective images; The mobile terminal is also used to store image data after the user annotates the generated result perspective image in chronological order.

[0020] By adopting the above solution, the user is allowed to preview, edit and store the result perspective image, which is convenient for the user to perform subsequent viewing and analysis.

[0021] Preferably, the guide rails have two groups, each group of guide rails is two linear guide rails, which are respectively installed in the X and Y directions, and each linear guide rail adopts a rolling bearing or a sliding bearing.

[0024] By adopting the above solution and using Bluetooth wireless technology, a relatively stable communication connection can be achieved.

[0025] In summary, this application has the following beneficial effects: 1.

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a structural schematic diagram of a desktop translational X-ray fluoroscopy system described in a specific embodiment; Figure 2 It is a diagram of an X-ray instrument application interface in a mobile terminal of a desktop-level translational X-ray instrument system described in a specific embodiment. DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] Example 1 like Figure 1 As shown, the embodiment of the present application discloses a desktop-level translational X-ray fluoroscopy system, which specifically includes: a housing 1, a rechargeable battery 2, an X-ray transmitter 3, an X-ray receiver 4, a guide rail 5, a stepper motor 6, a camera device 7, and a mobile terminal 8.

[0029] Specifically, the housing 1 is made of a transparent X-ray radiation shielding material, such as lead glass, and is used to fix and install a rechargeable battery 2, an X-ray transmitter 3, an X-ray receiver 4, a guide rail 5, a stepper motor 6, a camera device 7, etc. A storage platform for storing the fluoroscopic object or a fixing device for fixing the fluoroscopic object is provided in the housing, and the storage platform and the fault device are both made of a specially designed composite material or a material composed of light elements that hardly affects the propagation of X-rays.

[0030] The rechargeable battery 2 is used to provide power, so that the desktop translational X-ray fluoroscopy system operates independently of an external power source, thereby increasing portability and flexibility.

[0031] An X-ray emitter 3, used for emitting an X-ray beam to penetrate the object to be fluoroscopically examined; The X-ray receiver 4 is used to receive the X-rays that pass through the fluoroscopic object and convert the received X-rays into electrical signals through an electro-optical converter, and then process the electrical signals using a signal processing circuit to finally generate a fluoroscopic image.

[0032] The guide rails 5 are driven by a stepper motor 6. There are two sets of guide rails. Each set of guide rails is two linear guide rails, which are installed in the X and Y directions respectively. The two sets of guide rails are symmetrical in the horizontal plane, and there is a certain interval in the middle to accommodate the object to be fluoroscopic. Each set of guide rails is used to fix and control the movement of the X-ray transmitter or the X-ray receiver on a two-dimensional plane. The two sets of guide rails adopt a rolling bearing, a sliding bearing or a linear guide rail track structure design, and are synchronously driven by a stepper motor, so that the X-ray transmitter and the X-ray receiver move synchronously on the two-dimensional plane.

[0033] The stepper motor 6 is used to drive the guide rail 5 so that the X-ray transmitter and the X-ray receiver move synchronously on the guide rail 5 .

[0034] The camera device 7 is fixedly installed in the housing 1 and is used to collect images of the object being viewed. Considering the convenience and flexibility of the device, a micro camera device is selected.

[0035] The mobile terminal 8 establishes a communication connection with the X-ray transmitter, the X-ray receiver, the stepping motor and the camera device through wireless technology, and the mobile terminal is designed with an X-ray instrument application interface, such as Figure 2 As shown; it is used to receive user triggers according to the designed application interface, generate corresponding operation instructions and communicate and transmit data with each device that has established a communication connection; during the data transmission process, a specific data format or protocol can be defined. The data format includes an identification field, a data field, a timestamp field, a check field and a control field. The identification field is used to identify the source and type of the data, so that the mobile phone application can correctly parse the data. The data field contains the actual perspective image data. The timestamp field records the generation time of the data, which is helpful for subsequent data processing and analysis. The check field is used to verify the integrity of the data to ensure that the data has not been tampered with or lost during the transmission process. The control field contains some control information, such as the start and end flags of data transmission. In this embodiment, the wireless technology uses Bluetooth connection mode.

[0036] Specifically, considering that the user has corresponding perspective requirements for the perspective object, such as the perspective requirements for a specific part of the perspective object, the X-ray perspective instrument application interface corresponds to setting a sub-application interface of the first mobile operation interface (human operation interface) and a sub-application interface of the generated result feedback interface. The first mobile operation interface is provided with and displayed with operation buttons for the user to select a moving direction and a moving distance; the generated result feedback interface is provided with and displayed with feedback operation buttons, such as: satisfied, dissatisfied, dissatisfied and regenerate, etc., for the user to provide feedback output on the generated result diagram.

[0037] It can be seen that the mobile terminal 8 is used to generate a first movement instruction according to the user triggering operation on the designed first movement operation interface, wherein the first movement instruction includes: preset position movement information, such as: preset movement direction and preset distance; convert the first movement instruction into a pulse signal and send it to the stepper motor, so that the stepper motor 6 controls the rotation angle and step length according to the received pulse signal, and then drives the guide rail 5 to make the X-ray transmitter and the X-ray receiver move synchronously along the preset movement direction and preset movement distance; It is also used to receive and process perspective images in real time, and generate result perspective images through reconstruction algorithms; the specific process includes: stitching perspective image data according to the perspective image data received in real time, combined with preset position movement information; using deep learning models, such as convolutional neural networks, to remove noise from the perspective image after splicing, and using contrast enhancement technology to enhance the perspective image; finally, using an iterative reconstruction algorithm for the perspective image after denoising and enhancement to more accurately reconstruct the original perspective image, thereby obtaining the final result perspective image.

[0038] It is also used to generate a regeneration result operation instruction triggered by the user on the result feedback interface, re-process and reconstruct the received perspective image according to the regeneration result operation instruction, regenerate the result perspective image and save each generated result perspective image in chronological order.

[0039] In addition, the X-ray instrument application interface also supports preview and editing of result perspective images; the mobile terminal 8 is also used to store image data after the user annotates the generated result perspective image. In order to facilitate the user to find and compare the perspective images edited by themselves, they can be stored in chronological order.

[0040] The implementation principle of the system described in this embodiment is: during use, the user controls the X-ray transmitter to perform translational scanning on the X-axis and Y-axis guide rails through the first mobile operation interface of the mobile terminal, and the X-ray receiver moves synchronously and receives X-ray rays and generates a perspective image. The generated perspective image data is transmitted to the mobile terminal in real time via Bluetooth, and is processed by the image processing and reconstruction algorithm to generate a clear perspective image, which is displayed on the mobile terminal.

[0041] Example 2 The difference of this embodiment 1 lies in the design of the guide rail. Considering that there may be movement errors in the execution process after the first movement instruction is issued, in order to avoid movement errors, closed-loop control and precise position control are implemented to ensure the accuracy and stability of the fluoroscopic scan. A position feedback device closely connected to the stepper motor is installed on the guide rail, including: a photoelectric encoder or a Hall sensor to detect the rotation angle and position of the stepper motor, combined with the previous moment position of the X-ray transmitter and the X-ray receiver (the initial moment position is known and is a limited position), and then obtain the position information of the X-ray transmitter and the X-ray receiver at the current moment. The system also includes: The position feedback device establishes a connection with the mobile terminal through wireless technology, and is used to collect the position information of the X-ray transmitter and the X-ray receiver in real time and feed it back to the mobile terminal.

[0042] The mobile terminal establishes a connection with the position feedback device through wireless technology, and is also used to receive feedback position information in real time; compares the position movement information corresponding to the first movement instruction with the feedback position information received before and after the X-ray receiver is moved according to the first movement instruction, and obtains a comparison result. If the error between the comparison results is greater than the preset error, a position compensation instruction is generated according to the comparison result to control the stepper motor to continue driving the guide rail. For example: the position movement information corresponding to the first movement instruction is to move 5cm to the left, and the feedback position information received before and after the X-ray receiver is moved according to the first movement instruction is to move 3cm to the left. There is a movement error of 1cm, which is greater than the preset error of 0.1cm, and a corresponding position compensation instruction is generated to continue to move 1cm to the left.

[0043] The implementation principle of the system described in this embodiment is: the user sends a first movement instruction through the mobile terminal, and the system controller converts the first movement instruction into a corresponding pulse signal after receiving it and sends it to the stepper motor, thereby driving the X-ray emitter to move precisely on the guide rail. At the same time, the position feedback device monitors the rotation angle and position of the stepper motor in real time, obtains the position information of the X-ray emitter and sends the feedback information to the mobile terminal, and the mobile terminal generates a position compensation instruction in response to achieve closed-loop control and precise position control, further ensuring the accuracy and stability of the fluoroscopic scan.

[0044] In addition, considering that the X-ray transmitter and the X-ray receiver have moved to the edge of the guide rail and cannot continue to complete the instructions, the movement instructions issued by the user cannot be executed even through position compensation. In order to promptly remind the user of this situation and facilitate the user to adjust the movement instructions in time, the following method is used to complete the judgment reminder.

[0045] The mobile terminal is further configured to generate a prompt message indicating that the first movement instruction cannot be executed if there is still an error in the comparison result between the position movement information corresponding to the first movement instruction obtained after the preset number of position compensation instructions are issued and the feedback position information received before and after the X-ray emitter is moved according to the first movement instruction and the preset number of position compensation instructions, and the error is greater than the preset error. In this embodiment, the preset number of times is 3 times.

[0046] In addition, by recording and statistically analyzing the unexecutable movement instructions generated by the user's history, the user can be guided to avoid generating unexecutable movement instructions as much as possible, and the judgment reminder can be completed in the following way.

[0047] The mobile terminal is further used to record historical prompt information of the first movement instruction that cannot be executed, count and analyze the position movement information corresponding to the historical prompt information of the first movement instruction that cannot be executed, and form a position movement information range for the position movement information corresponding to the historical prompt information of the first movement instruction that cannot be executed and has an appearance frequency greater than a preset frequency; Determine whether the position movement information corresponding to the new first movement instruction prompt information triggered by the user in the first movement operation interface is within the position movement information range. If so, generate a prompt message that the first movement instruction may not be executed and display it on the first movement operation interface first. After continuing to execute the first movement instruction triggered by the user in the first operation interface, convert the generated first movement instruction into a pulse signal and send it to the stepper motor.

[0048] Example 3 The difference of this embodiment 1 lies in the design of the X-ray instrument application interface of the mobile terminal. The X-ray instrument application interface is also provided with an application sub-interface of the perspective mode selection interface, in which there are multiple perspective modes for the user to select, and each perspective mode is provided with preset perspective parameters for a preset type of perspective object; the system also includes: The mobile terminal is further used to generate a perspective parameter adjustment instruction according to the perspective mode selected by the user in the perspective mode selection interface, and convert the generated perspective parameter adjustment instruction into an electrical signal and send it to the X-ray transmitter and the X-ray receiver, so that the X-ray transmitter adjusts the X-ray emission intensity accordingly, and the X-ray receiver adjusts the receiving parameters accordingly. For example, when the user selects the first perspective mode, the first perspective parameter adjustment instruction is generated accordingly, so that the X-ray transmitter adjusts the X-ray emission intensity to the preset first X-ray emission intensity, and the X-ray receiver adjusts the receiving parameters to the preset first receiving parameters.

[0049] The implementation principle of the system described in this embodiment is as follows: during use, the user triggers and selects a specific perspective mode through a mobile terminal, and a corresponding perspective parameter adjustment instruction is generated according to the perspective mode selected by the user and sent to the X-ray transmitter and the X-ray receiver. When the user controls the X-ray transmitter through the mobile terminal to perform translational scanning on the X-axis and Y-axis guide rails with the adjusted X-ray emission intensity, the X-ray receiver receives the X-ray rays passing through the perspective object with the adjusted receiving parameters, generates a perspective image and transmits it to the mobile terminal, and is processed by the image processing and reconstruction algorithm to generate a clear result perspective image.

[0050] Example 4 The difference of this embodiment 1 is the design of the X-ray instrument application interface of the mobile terminal. In order to further reduce the operation steps of the user, the translation movement perspective can be automatically performed. The system also includes: A micro camera device, used to collect image data of the object being viewed and send it to the mobile terminal; The X-ray instrument application interface also includes: a second mobile operation interface; The mobile terminal connected to the micro-camera device is also used to generate a trigger instruction according to the second mobile operation interface designed by the user, analyze and identify the contour and key points of the received image data of the perspective object by using image recognition technology (using image recognition technology based on neural grid), automatically plan the movement route according to the identified contour and key points, and correspondingly generate continuous second movement instructions and convert the second movement instructions into pulse signals and send them to the stepping motor; wherein each perspective object is planned to be set with key points; In order to avoid the situation where the user performs other operations during the process of the user operating system generating the second movement instruction, causing the system to generate the first movement instruction which affects the execution of the second movement instruction, the mobile terminal is configured not to support the simultaneous generation of the first movement instruction and the second movement instruction, that is, when the second movement instruction is generated, it is impossible to generate the first movement instruction, and when the first movement instruction is generated, it is impossible to generate the second movement instruction.

[0051] The implementation principle of the system described in this embodiment is as follows: during use, the user selects the automatic translation option through the second mobile operation interface of the mobile terminal, and the mobile terminal will identify the contours and key points of the perspective object collected by the micro-camera device, and then plan a movement route by itself, and generate continuous second movement instructions corresponding to the movement route to control the X-ray transmitter to perform translational scanning on the X-axis and Y-axis guide rails, and the X-ray receiver moves synchronously and receives X-rays and generates a perspective image. The generated perspective image data is transmitted to the mobile terminal in real time via Bluetooth, and is processed by image processing and reconstruction algorithms to generate a clear perspective image, which is displayed on the mobile terminal.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
