Those skilled in the art will understand that the present application is also applicable to other radiation imaging systems or imaging systems based on other high-frequency electromagnetic energy.

[0034] Figure 1 is a schematic diagram of the medical imaging system of the embodiments of the present application. As Figure 1As shown, the medical imaging system 100 includes a suspension device 110, a wall stand device 120, and a detection bed device 130 disposed in the scanning room 101, and a control device 150 disposed in the control room 102. The suspension device 110 includes a longitudinal guide rail 111, a transverse guide rail 112, a telescopic cylinder 113, a pulley 114, and an X-ray tube assembly 115.

[0035] Although some embodiments of the present application are described based on a suspended X-ray imaging system, the embodiments of the present application are not limited thereto.

[0036] For ease of description, in the present application, the x-axis, y-axis, and z-axis are defined such that the x-axis and y-axis are in a horizontal plane and perpendicular to each other, and the z-axis is perpendicular to the horizontal plane. Specifically, the direction of the longitudinal guide rail 111 is defined as the x-axis, the direction of the transverse guide rail 112 is defined as the y-axis direction, and the extension direction of the telescopic cylinder 113 is defined as the z-axis direction, and the z-axis direction is the vertical direction.

[0037] The longitudinal guide rail 111 and the transverse guide rail 112 are perpendicularly arranged. Among them, the longitudinal guide rail 111 is installed on the ceiling, and the transverse guide rail 112 is installed on the longitudinal guide rail 111. The telescopic cylinder 113 is used to carry the X-ray tube assembly 115.

[0038] The pulley 114 is disposed between the transverse guide rail 112 and the telescopic cylinder 113. The pulley 114 may include components such as a rotating shaft, a motor, and a drum. The motor can drive the drum to rotate around the rotating shaft, thereby driving the telescopic cylinder 113 to move along the z-axis and / or slide relative to the transverse guide rail. The pulley 114 can slide relative to the transverse guide rail 112, that is, the pulley 114 can drive the telescopic cylinder 113 and / or the X-ray tube assembly 115 to move in the y-axis direction. And the transverse guide rail 112 can slide relative to the longitudinal guide rail 111, thereby driving the telescopic cylinder 113 and / or the X-ray tube assembly 115 to move in the x-axis direction.

[0039] The telescopic cylinder 113 includes a plurality of cylindrical shapes with different inner diameters, and the plurality of cylindrical shapes can be sleeved in the cylindrical shape located above it in sequence from bottom to top to achieve telescoping. The telescopic cylinder 113 can be telescoped (or moved) in the vertical direction, that is, the telescopic cylinder 113 can drive the X-ray tube assembly to move in the z-axis direction. A rotating part is also provided at the lower end of the telescopic cylinder 113, and the rotating part can drive the X-ray tube assembly 115 to rotate.

[0040] The tube assembly 115 includes an X-ray tube that can generate X-rays and project the X-rays towards the expected region of interest (ROI) of the patient. Specifically, the X-ray tube can be positioned adjacent to a collimator that is used to align the X-rays to the expected region of interest of the patient. At least a portion of the X-rays can be attenuated by the patient and can be incident on the detectors 121 / 131. Additionally, not shown, the X-ray imaging system can further include a position-flexible handheld detector for imaging some joints or infants.

[0041] The suspension device 110 further includes a collimator 117 that is typically mounted below the X-ray tube, and the X-rays emitted by the X-ray tube irradiate the subject through the opening of the collimator 117. Among them, the size of the opening of the collimator 117 determines the irradiation range of the X-rays, that is, the area size of the field of view (FOV) of the exposure. The positions of the X-ray tube and the collimator 117 in the transverse direction determine the position of the exposure FOV on the subject. As is well known, X-rays are harmful to the human body, so it is necessary to control the X-rays so that they only irradiate the part of the subject that needs to be examined, that is, the region of interest (ROI).

[0042] The suspension device 110 further includes a tube control console 116 that is mounted on the tube assembly. The tube control console 116 includes a display screen and user interfaces such as control buttons for performing preparatory work before shooting, such as patient selection, protocol selection, and positioning.

[0043] The movement of the suspension device 110 includes the movement of the tube assembly along the x-axis, y-axis, and z-axis, as well as the rotation of the tube assembly in the horizontal plane (the axis of rotation is parallel or coincident with the z-axis) and in the vertical plane (the axis of rotation is parallel to the y-axis). In the above movements, motors are usually used to drive the rotating shafts to drive the corresponding components to rotate, thereby realizing the corresponding movement or rotation, and the corresponding control components are generally installed in the trolley 114. The X-ray imaging unit further includes a motion control unit (not shown in the figure), and the motion control unit can control the above movements of the suspension device 110. Further, the motion control unit can receive control signals to control the corresponding components to perform corresponding movements.

[0044] The column device 120 includes a first detector assembly 121, a column (such as a chest radiograph stand) 122, and a connecting portion 123. The connecting portion 123 includes a support arm perpendicularly connected to the height direction of the column 122 and a rotating bracket mounted on the support arm. The first detector assembly 121 is mounted on the rotating bracket. The column device 120 further includes a detector driving device disposed between the rotating bracket and the first detector assembly 121. Driven by the detector driving device, it moves on the plane supported by the rotating bracket along a direction parallel to the height direction of the column 122. The first detector assembly 121 can further rotate relative to the support arm at a certain angle with respect to the column. The first detector assembly 121 has a plate-like structure, and its direction is variable so that the X-ray incident surface becomes vertical or horizontal according to the incident direction of the X-ray.

[0045] In some embodiments, the detector in the embodiments of the present application may include the first detector assembly 121 of the column device 120. Among them, the housing of the detector is a housing for accommodating the internal components of the detector. For example, it is a housing for accommodating the internal components of the first detector assembly 121. The support assembly for supporting the detector may include the rotating bracket of the column device 120 for supporting the first detector assembly 121.

[0046] The examination table device 130 includes a second detector assembly 131, a table board 132, and a base 133. The second detector assembly 131 is located below the table board 132, and the base 133 supports the second detector assembly 131 and the table board 132.

[0047] In some embodiments, the detector in the embodiments of the present application may include the second detector assembly 131 of the examination table device 130. Among them, the housing of the detector is a housing for accommodating the internal components of the detector. For example, it is a housing for accommodating the internal components of the second detector assembly 131. The support assembly for supporting the detector may include the base 133 of the examination table device 130 for supporting the second detector assembly 131.

[0048] The selection or use of the first detector assembly 121 and the second detector assembly 131 can be determined based on the patient's imaging site and / or imaging protocol, or can be determined based on the position of the subject obtained by camera imaging to perform imaging examinations in the lying or standing positions.

[0049] Figure 1 Only an example diagram of the column and the examination table is shown. Those skilled in the art should understand that columns and / or examination tables in any form or arrangement can be selected, or only columns can be installed. The columns and / or examination tables do not limit the overall solution of the present application.

[0050] In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller is configured to command the X-ray source to emit X-rays for image exposure. The detector controller is configured to select a suitable detector among a plurality of detectors and coordinate the control of various detector functions. For example, it automatically selects a corresponding detector according to the position or posture of the subject, or may perform various signal processing and filtering functions. Specifically, it is used for initial adjustment of dynamic range, interleaving of digital image data, etc. In some embodiments, the control device may provide power and timing signals for controlling the operation of the X-ray source and the detector.

[0051] In some embodiments, the control device may also be configured to use digital signals to reconstruct one or more desired images and / or determine useful diagnostic information corresponding to the patient. The control device may include one or more dedicated processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), or other suitable processing devices.

[0052] Of course, the medical imaging system may also include other numbers, configurations, or forms of control devices. For example, the control device may be local (e.g., collocated with one or more medical imaging systems 100, such as within the same facility and / or the same local network); in other implementations, the control device may be remote and thus can only be accessed via a remote connection (e.g., via the Internet or other available remote access technologies). In a particular implementation, the control device may also be configured in a cloud-like manner and can be accessed and / or used in a manner substantially similar to the way other cloud-based systems are accessed and used.

[0053] The system 100 further includes a storage device (not shown in the figure), and the processor may store digital signals in the memory. For example, the memory may include a hard disk drive, a floppy disk drive, a CD read / write drive, a digital versatile disk drive, a flash drive, and / or solid state memory. The memory may also be integrated with the processor to effectively use the footprint and / or meet the expected imaging requirements.

[0054] The system 100 further includes an input device 160, which may include a keyboard, a mouse, a voice-activated control device, a touch screen (which may also serve as the display device described later), a trackball, or any other suitable input device in the form of an operator interface. The operator can input operation signals / control signals to the control device through the input device.

[0055] The system 100 further includes a display device 151 (e.g., a touch screen or a display screen), and the display device 151 may be used to display operation interfaces such as a list of subjects, subject positioning or exposure settings, and images of the subject.

[0056] In some embodiments, the medical imaging system may further include a camera device 140. The subject can be photographed by the camera device to obtain a photographed image including the subject, such as a static image or a series of frame images in a dynamic real-time video stream, for assisting in positioning and exposure setting, etc. The camera device can be mounted on the suspension device, such as on the side of the collimator 117, etc. The embodiments of the present application do not limit this.

[0057] Figure 2 It is a schematic diagram of the detector identification device according to the embodiment of the present application. As Figure 2 shown, the detector identification device 200 includes a marking module 201 and an identification module 202. Among them, the marking module 201 is associated with the detector and includes at least one magnetic block 2011. The identification module 202 senses the magnetic block 2011 and generates the marking information of the detector according to the sensing result.

[0058] According to the above embodiments, the medical imaging system can obtain the marking information of the detector. Even in the case of more than one detector, different detectors can be identified, so that the operation process can be simplified and misoperation can be avoided. Moreover, by marking the detector in the way of magnetic blocks, the cost can be saved, it is easy to implement, and the reliability of the marking information can be ensured.

[0059] In some embodiments, one or more detectors may be included in the medical imaging system. For example, as Figure 1 shown in the medical imaging system, 2 detectors may be included. The detector can be a wireless communication detector or a wired communication detector. The present application does not make specific limitations on this.

[0060] In some embodiments, the marking module 201 can be associated with the detector in various ways. For example, the marking module 201 can be arranged on the detector, or the marking module 201 can be arranged on the supporting component that supports the detector.

[0061] In some embodiments, when the marking module 201 is arranged on the detector, the identification module 202 can be arranged on the supporting component that supports the detector. Taking Figure 1 the medical imaging system shown as an example, the marking module 201 can be arranged on the first detector assembly 121, and the identification module 202 can be arranged on the rotating bracket for supporting the first detector assembly 121; or, the marking module 201 can be arranged on the second detector assembly 131, and the identification module 202 can be arranged on the base 133 for supporting the second detector assembly 131.

[0062] In some embodiments, when the marking module 201 is disposed on the support assembly that supports the detector, the identification module 202 may be disposed on the detector. For Figure 1 taking the medical imaging system shown in [Figure] as an example, the marking module 201 may be disposed on the rotating bracket for supporting the first detector assembly 121, and the identification module 202 may be disposed on the first detector assembly 121; alternatively, the marking module 201 may be disposed on the base 133 for supporting the second detector assembly 131, and the identification module 202 may be disposed on the second detector assembly 131.

[0063] Hereinafter, taking the marking module 201 being disposed on the detector as an example, the device according to the embodiments of the present application will be described exemplarily. It can be understood that the following description is equally applicable to the case where the marking module 201 is disposed on the component that supports the detector.

[0064] In some embodiments, the magnetic block 2011 may be made of various magnetic materials. For example, the magnetic block 2011 is made of a permanent magnet.

[0065] In some embodiments, the magnetic block 2011 may be disposed on the detector in a preset pattern. Among them, the preset patterns of the magnetic blocks 2011 of different detectors may be different. Since different patterns of the magnetic block 2011 correspond to different induction results, different marking information can be generated to distinguish different detectors.

[0066] In some embodiments, the marking information may be various information that can distinguish different detectors. That is, different detectors have different marking information.

[0067] The marking information can be represented in various ways. For example, the marking information can be represented by a magnetic induction signal, for example, the signal output by a magnetic inductor; or the marking information can also be represented by a signal obtained by processing the magnetic induction signal such as filtering, for example, it can be represented by high and low levels.

[0068] In some embodiments, the preset pattern of the magnetic block 2011 may include at least one of the quantity information, position information, or size information of the magnetic block 2011. For example, for different detectors, at least one of the quantity, position, or size of the magnetic block 2011 may be different. The present application is not limited thereto, and the preset pattern may also include other information of the magnetic block, as long as different induction results or marking information can be generated.

[0069] For example, different numbers of magnetic blocks 2011 may be set for different detectors. Figure 3 and Figure 4 are schematic diagrams of the preset pattern according to the embodiments of the present application. Taking two detectors as an example, as Figure 3As shown, on one detector, one magnetic block 2011 can be set; as Figure 4 shown, on another detector, two magnetic blocks 2011 can be set. When the identification module 202 senses the magnetic blocks 2011 of these two detectors, different sensing results can be generated, and then different marking information can be generated.

[0070] For example, as Figure 3 shown, the preset pattern includes one magnetic block 2011, and the marking information (detector ID) of the detector corresponding to this preset pattern can be 10 or 01; as Figure 4 shown, the preset pattern includes two magnetic blocks 2011, and the marking information (detector ID) of the detector corresponding to this preset pattern can be 11.

[0071] This application is not limited to this, and the magnetic blocks 2011 can also be other quantities. For example, one detector is not provided with magnetic blocks, and the other detector is provided with one or more magnetic blocks.

[0072] For another example, for different detectors, the magnetic blocks 2011 can be set at different positions. Taking two detectors as an example, on one detector, the magnetic block can be set at the first preset position; on the other detector, the magnetic block can be set at the second preset position different from the first preset position. When the identification module 202 senses the magnetic blocks of these two detectors, different sensing results can be generated, and then different marking information can be generated.

[0073] For yet another example, for different detectors, magnetic blocks 2011 of different sizes can be set. Taking two detectors as an example, on one detector, a relatively small magnetic block can be set; on the other detector, a relatively large magnetic block can be set. When the identification module 202 senses the magnetic blocks of these two detectors, the sensing intensity of the small magnetic block is less than that of the large magnetic block. Thus, different sensing results can be generated, and then different marking information can be generated.

[0074] Next, the structure of the marking module 201 will be exemplarily described with reference to the accompanying drawings.

[0075] In some embodiments, the marking module 201 can be connected to the housing of the detector. By setting the marking module 201 on the housing of the detector, it is convenient for the identification module 202 to sense the magnetic blocks 2011 of the marking module 201, so as to ensure the reliability of the sensing result and further ensure the reliability of the marking information.

[0076] In some embodiments, the marking module 201 can be connected to the housing of the detector in various ways. For example, the housing of the detector can be provided with a groove recessed toward the inside of the detector, and the marking module 201 can be provided in the groove. Thus, when the detector is installed in a support assembly for supporting the detector, interference between the marking module 201 and the support assembly can be avoided, and miniaturization of the medical imaging system is facilitated.

[0077] In some embodiments, the marking module 201 can be accommodated in a groove provided in the housing of the detector. For example, the groove can accommodate an interface used for operations such as initial registration of the detector, such as a Type-C interface. Since the interface will no longer be used after the initial registration of the detector is completed, the interface can be removed from the detector, and the marking module 201 can be accommodated in the groove originally accommodating the interface. In this way, changes to the original structure of the detector can be reduced, making it easier to implement.

[0078] The present application is not limited thereto, and the marking module 201 may also be disposed on other structures of the housing of the detector, or the marking module 201 may also be disposed inside the detector, as long as it can be accurately sensed by the recognition module 202 .

[0079] Figure 5 201 is a schematic diagram of the marking module 201 of the embodiment of the present application. Figure 5 As shown, the marking module 201 may further include a storage component 2012. The storage component 2012 is connected to the housing of the detector and is used to store the magnetic block 2011. The storage component 2012 stores the magnetic block 2011, which can prevent the magnetic block 2011 from falling off or generating an unexpected displacement relative to the detector, thereby ensuring the reliability of the sensing result and further ensuring the reliability of the marking information.

[0080] In some embodiments, Figure 5 As shown, the storage assembly 2012 may include: a positioning member 2012-1 and a cover plate 2012-2. The positioning member 2012-1 may be connected to the housing of the detector, and a positioning hole H1 for storing the magnetic block is formed on the side of the housing away from the detector. The cover plate 2012-2 may be connected to the positioning member 2012-1 in a manner of clamping the magnetic block 2011. Through the above-mentioned sandwich structure (also called a sandwich structure), the magnetic block 2011 can be firmly fixed in a preset position to prevent the magnetic block 2011 from being displaced relative to the housing of the detector.

[0081] In some embodiments, Figure 5 As shown, in the positioning member 2012 - 1 , the shape and / or number of the positioning holes H1 match the shape and / or number of the magnetic blocks 2011 .

[0082] For example, the inner diameter of the positioning hole can be slightly larger than the outer diameter of the magnetic block 2011, thereby facilitating the installation of the magnetic block 2011. The shapes of the magnetic block 2011 and the positioning hole H1 can be approximately circular, and such a design facilitates the installation of the magnetic block 2011. The present application is not limited thereto, and the shapes of the magnetic block 2011 and the positioning hole can also be other shapes.

[0083] For another example, the number of the positioning holes H1 can be equal to the number of the magnetic blocks 2011, or larger than the number of the magnetic blocks 2011.

[0084] In some embodiments, as Figure 5 shown, the positioning hole H1 can be a bottomed hole portion, that is, a blind hole. The present application is not limited thereto, and the positioning hole can also be a through hole.

[0085] In some embodiments, as Figure 5 shown, the positioning hole H1 is formed in the positioning member 2012-1. The present application is not limited thereto, and the positioning hole H1 can also be formed on the surface of the cover plate 2012-2 close to the detector.

[0086] In some embodiments, the receiving assembly 2012 can be connected to the housing of the detector in various ways. As Figure 5 shown, the positioning member 2012-1 and the cover plate 2012-2 of the receiving assembly 2012 can be formed with through holes, and fixing components such as screws can pass through the through holes to be connected to the housing of the detector. The present application is not limited thereto, and the receiving assembly 2012 can also be connected to the housing by means of bonding, clamping, or riveting.

[0087] In addition, the receiving assembly 2012 can also be other structures. For example, the receiving assembly 2012 can only include a positioning member, and a positioning hole is formed on the side surface of the positioning member close to the detector. The positioning member is connected to the housing of the detector and jointly clamps the magnetic block with the housing of the detector.

[0088] The above is only an exemplary description of the marking module 201. Among them, the marking module 201 can also be other structures, and the present application does not make specific limitations thereto.

[0089] Next, the structure of the identification module 202 will be described exemplarily with reference to the accompanying drawings.

[0090] In some embodiments, the identification module 202 can be connected to the supporting assembly that supports the detector. The supporting assembly can be various components capable of supporting the detector. For example, the aforementioned rotating bracket or the base 133, etc.

[0091] In some embodiments, as Figure 2As shown, the identification module 202 may include at least one magnetic inductor 2021. The magnetic inductor 2021 is disposed opposite to the magnetic block 2011, and the distance between the magnetic inductor 2021 and the magnetic block 2011 is less than a first preset distance. By disposing the magnetic inductor 2021 opposite to the magnetic block 2011 and making the distance between the oppositely disposed magnetic inductor 2021 and magnetic block 2011 less than the first preset distance, the reliability of the induction result can be ensured, and thus the reliability of the marking information can be ensured.

[0092] The first preset distance may be related to the magnetic field strength of the magnetic block 2011 and / or the induction ability of the magnetic inductor 2021.

[0093] Figure 6 is a schematic diagram of the magnetic inductor according to an embodiment of the present application. As Figure 6 shown, the identification module 202 includes at least one magnetic inductor 2021. Among them, one magnetic inductor 2021 can be used to sense one magnetic block 2011 at a position opposite thereto. Generally, the number of magnetic inductors 2021 corresponds to the number of encoding bits of the magnetic block 2011. The present application is not limited thereto, and the number of magnetic inductors 2021 may also be greater than the number of encoding bits of the magnetic block 2011. In this case, the marking information can be determined by using the induction results of some of the magnetic inductors 2021.

[0094] In some embodiments, a second preset distance may be provided between multiple magnetic inductors 2021, whereby interference of other magnetic blocks 2011 on the induction result can be avoided.

[0095] Similar to the first preset distance, the second preset distance may also be related to the magnetic field strength of the magnetic block 2011 and / or the induction ability of the magnetic inductor 2021.

[0096] In some embodiments, as Figure 2 shown, the identification module 202 may further include a mounting component 2022. The mounting component 2022 can connect the magnetic inductor 2021 and a support component (not shown) that supports the detector, and mount the magnetic inductor 2021 on the support component in a floating manner in a first direction, which is, for example, the direction in which the magnetic inductor 2021 is opposite to the magnetic block 2011, and can also be referred to as the relative direction.

[0097] By mounting the magnetic inductor 2021 in a floating manner through the mounting component 2022, it can be ensured that the gap between the magnetic inductor 2021 and the magnetic block 2011 is less than the first preset distance, and thus the reliability of the induction result can be ensured, and further the reliability of the marking information can be ensured.

[0098] Figure 7 is a schematic diagram of the mounting component according to an embodiment of the present application. In some embodiments, as Figure 2 and Figure 7As shown, the installation component 2022 may include: a main body member 20221, a guiding member 20222, and an elastic member 20223. Among them, the main body member 20221 is connected to the magnetic inductor 2021.

[0099] As Figure 7 shown, the first end A1 of the guiding member 20222 is connected to a support component (not shown), and the main body member 20221 drives the magnetic inductor 2021 to move along the guiding member 20222. The first end B1 of the elastic member 20223 is connected to the main body member 20221, and the second end B2 of the elastic member 20223 is connected to a support component (not shown).

[0100] By providing the elastic member 20223 in the installation component 2022, when the marking module 201 abuts against the recognition module 202, the position of the recognition module 202 can be adjusted accordingly according to the position of the marking module 201. Thus, the marking module 201 and the recognition module 202 can be kept in an abutting state, so that the distance between the relatively arranged magnetic inductor 2021 and the magnetic block 2011 can be ensured to be less than the first preset distance.

[0101] In some embodiments, the main body member 20221 and the magnetic inductor 2021 can be connected in various ways. For example, the magnetic inductor 2021 can be connected to the main body member 20221 by means of screw connection, bonding, snap fit, or riveting, etc.

[0102] In some embodiments, the guiding member 20222 can be various structures with a guiding function. For example, the guiding member 20222 can be a guiding rod, or it can also be a guide rail, etc. For example, as Figure 7 shown, the guiding member 20222 can be substantially columnar, and its extending direction is the first direction. The main body member 20221 is formed with a hole portion H2, and at least a part of the guiding member 20222 is located in the hole portion H2. Thus, the main body member 20221 can be moved along the guiding member 20222 in the first direction.

[0103] In some embodiments, in order to prevent the main body member 20221 from slipping off the guiding member 20222, a limiting portion A3 can be formed at the second end A2 of the guiding member 20222. For example, when the main body member 20221 is at the first position, the end face of the limiting portion A3 facing the support component abuts against the end face of the main body member 20221 facing the detector. Thus, the main body member 20221 cannot slide to a position farther from the support component than the first position, so that the main body member 20221 can be prevented from falling off.

[0104] This application is not limited thereto. The guiding member 20222 may also not be provided with the limiting portion A3, and other components or structures may be used to prevent the main body member 20221 from falling off. For example, the first end B1 of the elastic member 20223 may be fixedly connected to the main body member 20221, and the second end B2 of the elastic member 20223 may be fixedly connected to the supporting assembly, which can also prevent the main body member 20221 from falling off.

[0105] In some embodiments, the elastic member 20223 may be various elastic structures. For example, the elastic member 20223 may be a spring or the like. As described above, the two ends of the elastic member 20223 may be respectively fixedly connected to the main body member 20221 and the supporting assembly. This application is not limited thereto, and the two ends of the elastic member 20223 may also be respectively abutted against the main body member 20221 and the supporting assembly, or one end is fixedly connected and the other end is abutted, etc. Thereby, the installation operation of the elastic member 20223 can be simplified.

[0106] In some embodiments, the number of guiding members 20222 may be one or more; the number of elastic members 20223 may be one or more.

[0107] For example, the guiding member 20222 may be located at a position coinciding with the central axis of the main body member 20221, and the number of elastic members 20223 is multiple, at positions symmetric with respect to the main body member 20221. Thereby, the main body member 20221 can be prevented from tilting, ensuring that the main body member 20221 moves stably along the guiding member 20222.

[0108] As Figure 7 shown, the elastic member 20223 may be separately provided at different positions from the guiding member 20222. This application is not limited thereto, and the elastic member 20223 and the guiding member 20222 may also be arranged in other ways. For example, the elastic member 20223 may be sleeved on the outer peripheral side of the guiding member 20222, the first end B1 of the elastic member 20223 is connected to the main body member 20221, and the other end B2 is connected to the supporting assembly, or the other end B2 is connected to the guiding member 20222, and so on.

[0109] In some embodiments, as Figure 7 shown, the mounting assembly 2022 may further include a blocking member 20224. The blocking member 20224 may be connected to the main body member 20221, and the end face of the blocking member 20224 facing the detector may be located at a position flush with the end face of the magnetic inductor 2021 facing the detector, or the end face of the blocking member 20224 facing the detector may be located at a position closer to the detector than the end face of the magnetic inductor 2021 facing the detector. By providing the blocking member 20224, when the marking module 201 abuts against the identification module 202, the magnetic inductor 2021 can be prevented from being damaged due to impact.

[0110] As Figure 7 shown, the blocking member 20224 may include a connecting portion C1 connected to the main body member 20221 and a blocking piece C2 connected to the edge of the connecting portion C1 close to the detector and substantially perpendicular to the connecting portion C1. The blocking pieces C2 are respectively arranged on both sides of the magnetic inductor 2021. Thus, the magnetic inductor 2021 can be reliably protected from the impact of the detector. The surface of the blocking piece C2 close to the detector may be a substantially flat surface. Thus, the detector can be stably supported, and the inclination of the main body member 20221 can be further prevented.

[0111] The above is only an exemplary description of the identification module 202. Among them, the identification module 202 may also have other structures, and the present application does not make specific limitations thereon.

[0112] It should be noted that only the components or modules related to this embodiment are described above, but the present application is not limited thereto. The detector identification device may further include other components or modules. For the specific content of these components or modules, reference may be made to the related art.

[0113] According to the above embodiment, the detector identification device includes a marking module and an identification module. Among them, the marking module is associated with the detector and includes at least one magnetic block; the identification module senses the magnetic block and generates the marking information of the detector according to the sensing result. Thus, the medical imaging system can obtain the marking information of the detector. Even when there are more than one detector, different detectors can be identified, thereby simplifying the operation process and avoiding misoperation. Moreover, by marking the detector in the way of magnetic blocks, the cost can be saved, it is easy to implement, and the reliability of the marking information can be ensured.

[0114] The embodiment of the present application further provides a medical imaging system. Figure 8 It is another schematic diagram of the medical imaging system according to the embodiment of the present application. As Figure 8 shown, the system 800 includes: a detector 801, a detector identification device 802, and a controller 803.

[0115] Among them, the detector identification device 802 is used to generate the marking information of the detector 801. For the implementation manner of the detector identification device, reference may be made to the foregoing embodiment, and details are not repeated here. The controller 803 generates indication information related to the detector 801 according to the marking information of the detector 801 generated by the detector identification device 802.

[0116] In some embodiments, the indication information may include various information related to the detector 801. For example, the indication information may be used to indicate whether the corresponding detector is installed in the medical imaging system, the operating state of the corresponding detector, etc., or the indication information may be used to indicate the installation position of the detector 801 on the subsequent display, for example, the detector 801 is installed in the column device and / or the examination table device.

[0117] In some embodiments, in the medical imaging system 800, the detector 801 may include one or more detectors; the detector identification device 802 may include one or more detector identification devices. As Figure 8 shown, the detector 801 may include detectors 801-1 and 801-2; the detector identification device 802 may include detector identification devices 802-1 and 802-2. Among them, the detector identification device 802-1 is used to generate the first marking information of the detector 801-1, the detector identification device 802-2 is used to generate the second marking information of the detector 801-2, and the controller 803 may receive the first marking information and the second marking information, and then generate the corresponding indication information.

[0118] In some embodiments, the controller 803 may be separately configured from the controller of the medical imaging system itself. For example, the controller 803 may be configured as a chip connected to the controller of the medical imaging system, etc., and the two may control each other. Alternatively, the function of the controller may also be integrated into the controller of the medical imaging system itself. The embodiments of the present application do not limit this.

[0119] In some embodiments, the controller 803 includes a computer processor and a storage medium, and a program for performing predetermined data processing to be executed by the computer processor is recorded on the storage medium. The above storage medium may include, for example, ROM, floppy disk, hard disk, optical disk, magneto-optical disk, CD-ROM, or non-volatile memory card.

[0120] In some embodiments, as Figure 8 shown, the system 800 may further include a display 804. The display 804 displays the position information of the detector 801 according to the indication information.

[0121] For example, the display 804 may display the position of the detector currently installed in the medical imaging system. For example, it is displayed that a detector is installed in the column device and / or the examination table device in the medical imaging system. The present application is not limited to this, and the display may also display other information of the detector.

[0122] Figure 9 is another schematic diagram of the medical imaging system according to the embodiments of the present application. The following is an exemplary description of the specific implementation of the medical imaging system in combination with Figure 9 For the specific implementation of the medical imaging system, an exemplary description is given. AsFigure 9 As shown, in the medical imaging system 900, the magnetic sensors in the magnetic induction plate sense the magnetic blocks associated with the detectors, and the magnetic induction plate is connected to a control board equipped with a level conversion circuit and a control circuit (MCU / FPGA). Through logical control by the host computer, the identifier (ID) of the detector can be identified and the position of the detector can be displayed on the display.

[0123] As Figure 9 shown, the number of encoding bits of the magnetic blocks is 2, and 4 magnetic sensors are arranged in the magnetic induction plate. Among them, the induction results of 2 magnetic sensors (for example, magnetic sensor 2 and magnetic sensor 3) among the 4 magnetic sensors can be used to generate marker information. Alternatively, only 2 magnetic sensors can also be arranged in the magnetic induction plate.

[0124] When the signals in the magnetic sensors are triggered (that is, the magnetic sensors detect the corresponding magnetic blocks), the control board will monitor the signals of the magnetic sensors in real time and report the signals including the detector ID information to the host computer through a preset protocol.

[0125] When receiving the signal including the detector ID information, the host computer monitors the signal in real time. When the signal changes, the detector ID information can be updated in real time. The host computer controls the display to show the position of the detector corresponding to the detector ID in the medical imaging system. These information will help support users to optimize the work process.

[0126] In some embodiments, the level conversion circuit can be various circuits. For example, the level conversion circuit can include a Schmitt trigger, etc.

[0127] The medical imaging system includes but is not limited to a computed tomography (CT) system, a magnetic resonance imaging (MRI) system, a C-arm imaging system, a positron emission tomography (PET) system, a single photon emission computed tomography (SPECT) system, an ultrasound system, an X-ray imaging system, or any other suitable medical imaging system.

Thus, the medical imaging system can obtain the marking information of the detector. Even in the case of more than one detector, different detectors can be identified, thereby simplifying the operation process and avoiding misoperations. Moreover, by marking the detector in the form of a magnetic block, the cost can be saved, it is easy to implement, and the reliability of the marking information can be ensured.
