Description

Technical Field

[0001] This application relates to the field of medical imaging technology, and in particular to a detection device and a medical imaging system. Background Technology

[0002] In a medical imaging system, X-rays emitted from an X-ray source are directed at the object being examined and, after penetrating the object, are received by a detector, which is a matrix of discrete elements (e.g., pixels). The detector elements are read out to generate an output signal based on the amount or intensity of radiation impacting each pixel region. This signal is then processed to produce a medical image of the object being examined.

[0003] Image processing (e.g., post-processing) of the medical image can yield more information. For example, image processing includes converting a two-dimensional image into a three-dimensional image. The processed medical image can then be displayed on the display device of a medical imaging system, allowing physicians to perform operations such as rotating the three-dimensional image, straightening images of organs such as blood vessels, or measuring the three-dimensional dimensions of the image. Summary of the Invention

[0004] When using a detector to receive X-rays that penetrate an object, it is sometimes necessary to inspect different parts of the object. Therefore, the detector's position must be adjustable. In some technical solutions, the detector can be connected to a column via an arm that can move along the height of the column, thereby moving the detector to adjust its position. Furthermore, during inspection, a shielding component needs to be placed between the object being inspected and the detector to prevent the object from coming into contact with the moving detector.

[0005] The inventors of this application have discovered that in existing technical solutions: in order to meet the requirements of the detector's movement range, the height of the column needs to be set relatively high. However, taller columns are difficult to transport and install. In addition, in order to avoid interference between the taller columns and the facilities installed on the ceiling of the scanning room, more requirements are placed on the interior space of the scanning room. For example, sufficient space must be reserved between the ceiling of the scanning room and the top of the column to install other facilities. Furthermore, the operation of setting up shielding plates during inspection complicates the inspection process.

[0006] To address the aforementioned problems or at least similar issues, embodiments of this application provide a detection device and a medical imaging system. In the detection device of this application, the housing is connected to the column via a connecting arm, the detector is housed within the housing, and a first driving mechanism is provided to drive the detector to move within the housing. Thus, the detector can move relative to the connecting arm, the height of the column can be reduced, facilitating the transportation and installation of the column, reducing the requirements for the indoor space of the scanning room, and the housing itself can serve as a shield. Therefore, during inspection, operators do not need to set up special shielding components, thus simplifying the inspection process.

[0007] According to one aspect of the embodiments of this application, a detection device is provided, the detection device comprising:

[0008] A column that extends along a first direction;

[0009] A connecting arm extending along a second direction, one end of which is connected to a column; and

[0010] A detector assembly, which is connected to the other end of the connecting arm.

[0011] The detector assembly includes:

[0012] case;

[0013] The detector, which is disposed within the housing; and

[0014] A first drive mechanism, which is connected to the detector, drives the detector to move within the housing to adjust the position of the detector within the housing.

[0042] Figure 1 This is a schematic diagram of an X-ray imaging system according to an embodiment of this application. Figure 1 As shown, the X-ray imaging system 100 can be an example of a medical imaging system, which includes a suspension device 110, a wall stand device 120, and a test bed device 130 disposed in a scanning room 101, and a control device 150 disposed in a control room 102. The suspension device 110 includes a longitudinal guide rail 111, a transverse guide rail 112, a telescopic cylinder 113, a trolley 114, and an X-ray tube assembly 115.

[0043] Although some embodiments of this application are described based on a suspended X-ray imaging system, the embodiments of this application are not intended to be limited thereto. For example, the medical imaging system may also be other types of X-ray imaging systems, or other types of imaging systems, such as computed tomography (CT) systems, positron emission tomography (PET) systems, magnetic resonance imaging (MRI) systems, etc.

[0044] For ease of description, in this application, the x-axis, y-axis and z-axis are defined as follows: the x-axis and y-axis are located in the horizontal plane and are 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, and the extension direction of the telescopic cylinder 113 is defined as the z-axis, which is the vertical direction.

[0045] The longitudinal guide rail 111 and the transverse guide rail 112 are arranged vertically, wherein the longitudinal guide rail 111 is mounted on the ceiling, and the transverse guide rail 112 is mounted on the longitudinal guide rail 111. The telescopic cylinder 113 is used to carry the X-ray tube assembly 115.

[0046] A trolley 114 is positioned between the transverse guide rail 112 and the telescopic cylinder 113. The trolley 114 may include a rotating shaft, a motor, and a drum. The motor drives the drum to rotate around the rotating shaft, thereby causing the telescopic cylinder 113 to move along the z-axis and / or slide relative to the transverse guide rail. The trolley 114 can slide relative to the transverse guide rail 112, meaning it can drive the telescopic cylinder 113 and / or the X-ray tube assembly 115 to move along the y-axis. Furthermore, the transverse guide rail 112 can slide relative to the longitudinal guide rail 111, thereby causing the telescopic cylinder 113 and / or the X-ray tube assembly 115 to move along the x-axis.

[0047] The telescopic cylinder 113 includes multiple cylindrical sections with different inner diameters, which can be sequentially fitted into the upper cylinder from bottom to top to achieve telescopic movement. The telescopic cylinder 113 is telescopic (or movable) in the vertical direction, that is, the telescopic cylinder 113 can drive the X-ray tube assembly to move along the z-axis. The lower end of the telescopic cylinder 113 is also provided with a rotating part, which can drive the X-ray tube assembly 115 to rotate.

[0048] The X-ray tube assembly 115 includes an X-ray tube that can generate X-rays and project them onto the patient's region of interest (ROI). Specifically, the X-ray tube may be positioned adjacent to a collimator used to align the X-rays to the patient's ROI. At least a portion of the X-rays may be attenuated by the patient and may be incident on detectors (first detector assembly 121 and second detector assembly 131, as described below).

[0049] The suspension device 110 further includes a collimator 117, which is typically mounted below the X-ray tube. X-rays emitted from the X-ray tube pass through the opening of the collimator 117 and irradiate the object being inspected. The size of the opening of the collimator 117 determines the irradiation range of the X-rays, i.e., the size of the field of view (FOV). The lateral position of the X-ray tube and the collimator 117 determines the position of the FOV on the object being inspected. As is well known, X-rays are harmful to the human body; therefore, it is necessary to control the X-rays to irradiate only the areas of the object to be inspected, i.e., the region of interest (ROI).

[0050] The suspension device 110 further includes a X-ray tube control device (console) 116, which is mounted on the X-ray tube assembly. The X-ray tube control device 116 includes a user interface such as a display screen and control buttons for pre-shooting preparations, such as patient selection, protocol selection, and positioning.

[0051] The movement of the suspension device 110 includes the movement of the X-ray tube assembly along the x-axis, y-axis, and z-axis, as well as the rotation of the X-ray tube assembly in the horizontal plane (rotation axis parallel to or coincident with the z-axis) and the vertical plane (rotation axis parallel to the y-axis). In these movements, a motor typically drives the rotating shaft to rotate the corresponding components, thereby achieving the corresponding movement or rotation. The corresponding control components are generally installed within the trolley 114. The X-ray imaging unit further includes a motion control unit (not shown in the figure), which can control the aforementioned movements of the suspension device 110. Furthermore, the motion control unit can receive control signals to control the corresponding components to perform corresponding movements.

[0052] The column assembly 120 includes a first detector assembly 121, a column 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 assembly 120 further includes a detector driving device disposed between the rotating bracket and the first detector assembly 121. Driven by the detector driving device, the detector assembly 121 moves along a direction parallel to the height direction of the column 122 on the plane supported by the rotating bracket. The first detector assembly 121 can also further rotate relative to the support arm, forming a certain angle with the column. The first detector assembly 121 has a plate-like structure with a variable orientation, so that the X-ray incident surface can be made vertical or horizontal depending on the incident direction of the X-rays.

[0053] The examination bed device 130 includes a second detector assembly 131. 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 based on the position of the subject being examined obtained by the camera, so as to perform imaging examinations in a supine or standing position. Figure 1 Only one example diagram of the column and testing bed is shown. Those skilled in the art should understand that any form or arrangement of the column and / or testing bed can be selected, or only the column can be installed. The column and / or testing bed are not limited to the overall scheme of this application.

[0054] In some embodiments, the medical imaging system includes a camera device 140 (e.g., a camera) that can capture images of the object under test, such as a static optical image or a series of frames of optical images in a dynamic real-time video stream, to assist in positioning and exposure settings, etc. The camera device can be mounted on a suspension device, such as on the side of a crowbar 117, but this embodiment is not intended to limit it. The camera device 140 includes one or more cameras, such as a digital camera, an analog camera, a depth camera, an infrared camera, or an ultraviolet camera, a 3D camera, a 3D scanner, or an RGB sensor, an RGB-D depth sensor, or other devices capable of capturing color image data of the target object.

[0055] In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller commands the X-ray source to emit X-rays for image exposure. The detector controller selects a suitable detector from among multiple detectors and coordinates the control of various detector functions, such as automatically selecting the corresponding detector based on the position or posture of the object being inspected, or performing various signal processing and filtering functions, specifically 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 detector.

[0056] 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, wherein 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.

[0057] Of course, medical imaging systems may also include other numbers, configurations, or forms of control devices. For example, control devices may be local (e.g., located in the same location as one or more X-ray imaging systems 100, such as within the same facility and / or the same local network); in other implementations, control devices may be remote and therefore accessible only via a remote connection (e.g., via the Internet or other available remote access technologies). In certain implementations, control devices may also be configured in a cloud-like manner and may be accessed and / or used in a manner substantially similar to accessing and using other cloud-based systems.

[0058] System 100 also includes a storage device (not shown) in which the processor can store digitized signals. For example, the storage device may include a hard disk drive, floppy disk drive, optical disc read / write drive, digital universal disk drive, flash memory drive, and / or solid-state memory. The storage device may also be integrated with the processor to efficiently utilize floor space and / or meet desired imaging requirements.

[0059] System 100 also includes an input device 160, which may include a keyboard, mouse, voice-activated control device, touch screen (or display device as described later), trackball, or any other suitable input device, etc., as a form of operator interface, through which the operator can input operation signals / control signals to the control device.

[0060] The system 100 also includes a display device 151 (e.g., a touch screen or a display screen), which can be used to display an interface for displaying a list of objects to be inspected, the placement or exposure settings of the objects to be inspected, and images of the objects to be inspected.

[0061] Currently, images captured by a camera device on a test object can be displayed on a display device. These images are distinct from medical images acquired through X-ray imaging. The captured images are used to assist in positioning or exposure settings. For example, assisting in positioning or exposure settings includes acquiring information about the test object, acquiring the shooting protocol, determining the shooting dose, posture, etc., and positioning based on the shooting protocol, as well as setting the size and position of the exposure area.

[0062] Figure 2 This is a schematic diagram of an X-ray imaging system with a movable detector.

[0063] like Figure 2 As shown, the detector 21 can be connected to the column 23 via the arm 22. The arm 22 can move along the height direction of the column 23 (i.e., move up and down), thereby moving the detector 21 to adjust its position. During inspection, a shielding component 24 is provided between the object being inspected 20 and the detector 21 to prevent the object being inspected 20 from contacting the moving detector 21. In addition, the object being inspected 20 can also step on the footstool 25 to adjust its position.

[0064] like Figure 2As shown, the suspension device 26 may include a trolley 260, a telescopic cylinder 261, and an X-ray tube assembly 262. The trolley 260 can move along a track (not shown) installed on the ceiling 200 of the scanning chamber. The trolley 260 carries the telescopic cylinder 261, and the telescopic cylinder 261 carries the X-ray tube assembly 262. For example, when the trolley 260 moves along the track, it can move the X-ray tube assembly 262 together with it; when the telescopic cylinder 261 performs telescopic movements to change its length, the position of the X-ray tube assembly 262 in the height direction can be adjusted; in addition, a rotating part is provided at the lower end of the telescopic cylinder 261, which can drive the X-ray tube assembly 262 to rotate.

[0065] The X-ray tube assembly 262 can generate X-rays and project X-rays onto the region of interest (ROI) of the object being inspected.

[0066] about Figure 2 For a more detailed description of the central suspension device 26, please refer to the documentation for [link to documentation]. Figure 1 Description of the central suspension device 110.

[0067] exist Figure 2 In the illustrated technical solution, in order to meet the requirements of the detector 21's range of movement in the height direction (for example, to ensure that the range of movement of the arm 22 allows the detector 21 to inspect the head of the object 20 being inspected), the height of the column 23 needs to be set relatively high. However, if the height of the column 23 is set too high, the difficulty of transporting and installing the column 23 will increase significantly. In addition, the taller column 23 is more likely to interfere with the facilities installed on the ceiling 200 of the scanning chamber (for example, the column 23 is likely to collide with the trolley 260 or the telescopic cylinder 261). Therefore, sufficient space must be reserved between the ceiling 200 of the scanning chamber and the top of the column 23 to install other facilities such as the trolley 260 or the telescopic cylinder 261. Furthermore, when inspecting the object 20 being inspected, the operation of setting up shielding components 24 and other operations will complicate the inspection process.

[0068] To address at least one or similar technical problems mentioned above, embodiments of this application provide a detection device and a medical imaging system.

[0069] The embodiments of this application are described in detail below.

[0070] Figure 3 This is a schematic diagram of a detection device according to an embodiment of this application. Figure 3 As shown, the detection device 300 includes: a column 31, a connecting arm 32, and a detector assembly 33.

[0071] The detection device 300 can be installed in the scanning chamber.

[0072] The column 31 extends along a first direction D1. In some examples, the first direction D1 may be the height direction of the column 31.

[0073] The column 31 can have a cuboid shape. When viewed along the first direction D1, the cross-section of the column 31 can be rectangular or square. Furthermore, this application is not limited to this, and the column 31 can also have other shapes.

[0074] like Figure 3 As shown, the lower end of the column 31 can be mounted on the base 310. The cross-section of the base 310 can be larger than that of the column 31, thereby increasing the stability of the column 31. The base 310 can be placed directly on the floor of the scanning room, or it can be fixed to the floor of the scanning room by fasteners (e.g., expansion bolts, adhesive, etc.).

[0075] The connecting arm 32 extends along the second direction D2. In some examples, the second direction D2 may intersect the first direction D1; for example, the second direction D2 may be perpendicular to the first direction D1. In one example, the first direction D1 is a vertical direction (e.g., the direction of the z-axis mentioned above), and the second direction D2 is a horizontal direction (e.g., the direction of the y-axis mentioned above).

[0076] One end 32A of the connecting arm 32 is connected to the column 31. In some examples, the connecting arm 32 can be fixedly mounted on the column 31. In other examples, the connecting arm 32 can be movably mounted on the column 31. For example, the column 31 has a slide rail (not shown) on the side 31A facing the connecting arm 32, and the slide rail can extend along a first direction D1; the connecting arm 32 is mounted on the slide rail and can move along the slide rail.

[0077] The other end 32B of the connecting arm 32 can be connected to the detector assembly 33, so that when the connecting arm 32 moves, it can drive the detector assembly 33 to move together.

[0078] like Figure 3 As shown, the connecting arm 32 may have a cuboid shape. When viewed along the second direction D2, the cross-section of the connecting arm 32 may be rectangular or square. Furthermore, this application is not limited to this; the connecting arm 32 may also have other shapes.

[0079] The outer surface of the connecting arm 32 may be provided with handles 321. The number of handles 321 may be one or more, for example, two. These two handles may be provided on two opposite surfaces of the connecting arm 32. By providing handles 321, the operator can easily move the connecting arm 32, thereby adjusting its position. Furthermore, in some examples, the handles 321 may be provided with buttons (not shown), which can be used to control at least one of the following three movements: the connecting arm 32 moving up and down along the D1 direction; the detector assembly 33 rotating about a first axis X1 perpendicular to the surface of the housing 331; and the rotating bracket 36 (described later)... Figure 8 , Figure 10 , Figure 11 , Figure 12 (As shown) it rotates about the second axis X2 so that the surface of the housing 331 is inclined relative to the horizontal plane. For a description of the above three movements, please refer to the description below.

[0080] The outer surface of the connecting arm 32 may also be provided with a handrail mounting portion 322, thereby enabling the handrail to be mounted on the connecting arm 32. The handrail mounting portion 322 may be located on the upper surface of the connecting arm 32. Alternatively, the handrail mounting portion 322 may be located at other positions on the connecting arm 32.

[0081] Figure 4 This is another schematic diagram of the detection device according to an embodiment of this application. For example... Figure 4 As shown, a handrail 323 is mounted on a handrail mounting portion 322. The handrail 323 can extend to the side of the detector assembly 33 away from the connecting arm 32 (e.g., the front side), so that when the subject is being inspected in front of the detector assembly 33, the subject can hold onto the handrail 323 to maintain stability or balance, thus improving the convenience of the inspection.

[0082] In the following description of this application, it will be referred to as Figure 3 The following description uses the case where the connecting arm 32 is not equipped with a handrail as an example; the content of this description also applies to... Figure 4 The case shown is where a handrail 323 is installed on the connecting arm 32.

[0083] Figure 5 This is a schematic diagram of the detector assembly of the internal detection device of the housing according to an embodiment of this application. Figure 5 As shown, the detector assembly 33 includes: a housing 331, a detector 332, and a first drive mechanism 333. The internal structure of the housing 331 is shown below. Figure 5 The housing 331 is shown in a dashed box.

[0084] Figure 3The three-dimensional structure of the housing 331 is shown. The housing 331 can have a cuboid shape, for example, the housing 331 has a length direction L, a width direction W, and a thickness direction T. When viewed along the length direction L, the cross-section of the housing 331 can be rectangular or square. Furthermore, this application is not limited to this, and the housing 331 can also have other shapes.

[0085] like Figure 5 As shown, detector 332 can be housed within housing 331. First drive mechanism 333 can be housed within housing 331.

[0086] The first drive mechanism 333 is connected to the detector 332, thereby enabling the first drive mechanism 333 to drive the detector 332 to move inside the housing 331 to adjust the position of the detector 332 inside the housing 331. For example, the first drive mechanism 333 can drive the detector 332 to move along the length L of the housing 331 inside the housing 331.

[0087] In some embodiments, the detector 332 can be connected to the first drive structure 333 via a connection board 34. For example, the connection board 34 is located inside the housing 331, and the connection board 34 can be mounted on the first drive mechanism 333. The detector 332 is mounted on the connection board 34, and the first drive mechanism 333 drives the connection board 34 to move within the housing 331, thereby moving the detector 332.

[0088] exist Figure 5 In order to show the surface structure of the connecting plate 34, the detector 332 is shown with a dashed box. The connecting plate 34 may be in a generally rectangular shape, with a portion of the four apex corners cut off to minimize interference between the connecting plate 34 and other components inside the housing 331 during movement.

[0089] The surface of the connecting plate 34 is provided with a first connecting portion 341. The first connecting portion 341 is used to mount the detector 332 to the connecting plate 34. In some examples, the first connecting portion 341 may be a bolt or a raised mounting pin, etc. The number of first connecting portions 341 may be one or more, for example, such as Figure 5 As shown, there are 6 first connecting parts 341.

[0090] The surface of the connecting plate 34 is also provided with a second connecting part 342 and a third connecting part 343, which are used to install the connecting plate 34 onto the first drive mechanism 333.

[0091] In addition, such as Figure 5As shown, the connecting plate 34 may also have an opening 344. The opening 344 facilitates heat dissipation from the back of the detector 332, and the cable connected to the back of the detector 332 can pass through the opening 344.

[0092] Figure 6 yes Figure 5 A schematic diagram excluding the connecting plate 34 shows the structure of the first drive mechanism 333. (See diagram below.) Figure 6 As shown, the first drive mechanism 333 may include a motor 3331 and a transmission device 3332. The rotation axis (not shown) of the motor 3331 is parallel to the length direction L; the transmission device 3332 transmits the power of the motor 3331 to the connecting plate 34, thereby driving the connecting plate 34 to move.

[0093] In some embodiments, such as Figure 6 As shown, the transmission device 3332 may include a lead screw. The transmission device 3332 may include: a lead screw 3333, a bearing 3330, a nut 3334, a slide rail 3335, and a slider 3336.

[0094] The bearing 3330 is provided in one or more (e.g., two) to support the lead screw 3333. The lead screw 3333 can be connected to the rotating shaft (not shown) of the motor 3331, thereby causing the lead screw 3333 to rotate about its length axis when the rotating shaft of the motor 3331 rotates. The lead screw 3333 can be arranged along the length direction L. The outer surface of the lead screw 3333 has threads. A nut 3334 is fitted onto the surface of the lead screw 3333, and the inner surface of the nut 3334 has threads. The threads on the inner surface of the nut 3334 mate with the threads on the outer surface of the lead screw 3333. Furthermore, the nut 3334 may also contain balls, thus forming a ball screw structure with the nut 3334 and the lead screw 3333.

[0095] The number of slide rails 3335 can be one or more (e.g., two), and the slide rails 3335 can be arranged parallel to the lead screw 3333. For example, two slide rails 3335 can be respectively arranged on both sides of the lead screw 3333 along the width direction W, thereby improving the stability of the connecting plate 34 during movement. The slider 3336 is sleeved on the outer surface of the slide rail 3335, and the slider 3336 slides under the guidance of the slide rail 3335.

[0096] like Figure 6 As shown, the nut 3334 may have a nut mounting portion 3337. The nut mounting portion 3337 can be coupled with... Figure 5 The second connecting portion 342 of the connecting plate 34 is aligned, and the nut mounting portion 3337 and the second connecting portion 342 can be connected by fasteners such as bolts, thereby mounting the connecting plate 34 on the nut 3334.

[0097] The slider 3336 may have a slider mounting part 3338. The slider mounting part 3338 can be coupled with... Figure 5 The third connecting part 343 of the connecting plate 34 is aligned, and the slider mounting part 3338 and the third connecting part 343 can be connected by fasteners such as bolts, thereby mounting the connecting plate 34 on the slider 3336.

[0098] exist Figure 6 In the transmission device 3332: when the motor 3331 rotates, it drives the lead screw 3333 to rotate; through the engagement between the threads of the lead screw 3333 and the nut, and the guidance of the slide rail 3335, the rotation of the lead screw 3333 is converted into the movement of the nut 3334, the slider 3336, and the connecting plate 34 along the length direction L. Changing the rotation direction of the motor 3331 can adjust the movement of the nut 3334, the slider 3336, and the connecting plate 34 toward one end or the other end of the length direction L.

[0099] Figure 7 This is another schematic diagram of the detector assembly of the internal detection device of the housing according to an embodiment of this application. Figure 7 and Figure 5 The difference is that, Figure 7 The first drive mechanism 333a and Figure 5 The first drive mechanism 333 has a different structure. For example... Figure 7 As shown, the first drive mechanism 333a may include a motor 3331a and a transmission device 3332a. The rotation axis (not shown) of the motor 3331a may be parallel to the width direction W; the transmission device 3332a transmits the power of the motor 3331a to the connecting plate 34, thereby driving the connecting plate 34 to move.

[0100] In some embodiments, such as Figure 7 As shown, the transmission device 3332a may include a belt. The transmission device 3332a may include: a guide shaft 3333a, a guide shaft support 3330a, a support member 3334a, a slide rail 3335, a slider 3336, a pulley 3339, and a belt 3340.

[0101] The guide shaft support 3330 is one or more (e.g., two) used to support the guide shaft 3333a. The guide shaft 3333a can be arranged along the length direction L. The support member 3334a is sleeved on the surface of the guide shaft 3333a and can slide along the guide shaft 3333a.

[0102] The number of slide rails 3335 can be one or more (e.g., two), and the slide rails 3335 can be arranged parallel to the guide shaft 3333a. For example, two slide rails 3335 can be respectively arranged on both sides of the guide shaft 3333a along the width direction W, thereby improving the stability of the connecting plate 34 during movement. The slider 3336 is sleeved on the outer surface of the slide rail 3335, and the slider 3336 slides under the guidance of the slide rail 3335.

[0103] exist Figure 7 In the example shown, the surface of the support member 3334a may have a mounting portion (not shown) that mates with the second connecting portion 342, thereby enabling the connecting plate 34 to be mounted on the support member 3334a. The surface of the slider 3336 may have a mounting portion (not shown) that mates with the third connecting portion 343, thereby enabling the connecting plate 34 to be mounted on the slider 3336.

[0104] like Figure 7 As shown, there can be two pulleys 3339, respectively located near both ends of the guide rail 3333a. One of the pulleys 3339 (for example, Figure 7 The lower pulley 3339 can be the driving pulley. This lower pulley 3339 is connected to the rotating shaft (not shown) of the motor 3331a, so that when the rotating shaft of the motor 3331a rotates, it drives the pulley 3339 to rotate; another pulley 3339 (e.g., Figure 7 The upper pulley 3339 can be a driven pulley. For example, the pulley 3339 can be a timing belt pulley. A belt 3340 is disposed on the outer periphery of the pulley 3339; for example, the belt 3340 is mounted on the outer periphery of both pulleys 3339. The belt 3340 can be connected to the connecting plate 34, thereby driving the slider 3336 to slide along the slide rail 3335.

[0105] In this application, Figure 7 The function of the upper pulley 3339 is to cooperate with the lower pulley 3339 to tension the belt 3340, so that the rotation of the lower pulley 3339 can drive the belt 3340 to move. In other examples, Figure 7 The upper pulley 3339 can be replaced by other components, as long as the component can cooperate with the lower pulley 3339 to tension the belt 3340.

[0106] exist Figure 7 In the transmission device 3332a: when the motor 3331a rotates, it drives... Figure 7The pulley 3339 on the lower side rotates; the rotation of the pulley 3339 drives the belt 3340 to move; the movement of the belt 3340 can drive the slider 3336 and the connecting plate 34 to move along the length direction L. Among them, changing the rotation direction of the motor 3331a can adjust the slider 3336 and the connecting plate 34 to move towards one end or the other end of the length direction L.

[0107] Figure 8 This is a side view of the detection device. (Example) Figure 8 As shown, in some embodiments, the detection device 300 further includes a second drive mechanism 35.

[0108] The second drive mechanism 35 is connected between the housing 331 and the other end 32B of the connecting arm 32. The second drive mechanism 35 drives the detector assembly 33 to rotate about a first axis X1 that is perpendicular to the surface of the housing 331.

[0109] Figure 9 This is a three-dimensional schematic diagram of the second drive mechanism. (See diagram below.) Figure 9 As shown, the second drive mechanism 35 includes: a first connecting part 351, a second connecting part 352, and a rotary motor 353.

[0110] The first connecting part 351 and the other end 32B of the connecting arm 32 (as shown in the figure) Figure 8 (As shown) connection, for example, the first connecting part 351 is connected to the other end 32B of the connecting arm 32 via the rotating bracket 36 described later (as shown). Figure 8 (As shown) The second connecting part 352 is connected to the housing 331 of the detector assembly 33. The second connecting part 352 rotates relative to the first connecting part 351 about the first axis X1.

[0111] The rotary motor 353 has a fixed part 3531 (e.g., stator) and a rotating part 3532 (e.g., rotor). The rotating part 3532 is rotatable relative to the fixed part 3531, for example, the rotating part 3532 can rotate about a first axis X1.

[0112] The fixing part 3531 is connected to the first connecting part 351. For example, the fixing part 3531 is connected to the first connecting part 351 by a plurality of fixing components 3533 such as bolts distributed circumferentially. The second connecting part 352 is provided on the rotating part 3532: for example, the connecting part 352 is a screw hole 3534 on the end face of the rotating part 3532, and there can be a plurality of screw holes 3534, for example, 6; or for example, the connecting part 352 can be an element mounted on the rotating part 3532, and the connecting part 352 is connected to the housing 331. Thus, when the rotating part 3532 rotates, it drives the connecting part 352 and the housing 331 to rotate around the first axis X1.

[0113] like Figure 8 As shown, in some embodiments, the detection device 300 further includes a rotating bracket 36. The rotating bracket 36 is rotatably mounted to the other end 32B of the connecting arm 32. For example, the rotating bracket 36 can rotate about a second axis X2, wherein the second axis X2 is perpendicular to both the first direction D1 and the second direction D2.

[0114] The rotating bracket 36 can be connected to the first connection portion 351 of the second drive mechanism 35, for example, by means of fastening elements such as bolts. Figure 9 (As shown) connection. Thus, when the drive rotating bracket 36 rotates around the second axis X2, it can drive the housing 331 to move, thereby causing the surface of the housing 331 to tilt relative to the horizontal plane.

[0115] Figure 10 This is a schematic diagram of a rotating support rotating at a predetermined angle. For example... Figure 10 As shown, when the rotating bracket 36 is rotated 90 degrees, the surface of the housing 331 facing the object being detected can change from a direction perpendicular to the horizontal plane to a direction parallel to the horizontal plane. This improves flexibility, allowing the detector 332 inside the housing 331 to receive X-rays at an appropriate angle.

[0116] Figure 11 This is a three-dimensional schematic diagram of the internal structure near the other end of the connecting arm. Figure 12 This is a three-dimensional schematic diagram of the internal structure near the other end of the connecting arm from another perspective. Figure 11 The housing of connecting arm 32 is not shown. Furthermore, Figure 10 It also shows a side view of the internal structure near the other end 32B of the connecting arm 32 with part of the outer casing of the connecting arm 32 removed.

[0117] like Figure 10 , Figure 11 and Figure 12 As shown, the detection device 300 also includes a first support rod 37.

[0118] One end 37a of the first support rod 37 is connected to the rotating bracket 36. For example, one end 37a of the first support rod 37 is rotatably connected (e.g., pivotally connected via a movable pin) to the rotating bracket 36. The other end 37b of the first support rod 37 is movably connected to the inside of the connecting arm 32. The first support rod 37 supports the rotating bracket 36 and provides torque to the rotating bracket 36 to support it.

[0119] The detection device 300 also includes a second support rod 38 and a third drive mechanism 39.

[0120] One end 38a of the second support rod 38 is connected to the rotating bracket 36. For example, one end 38a of the second support rod 38 is rotatably connected (e.g., pivotally connected via a movable pin) to the rotating bracket 36.

[0121] The third drive mechanism 39 is mounted on the connecting arm 32, for example, the third drive mechanism 39 is disposed inside the connecting arm 32. The third drive mechanism 39 is connected to the other end 38b of the second support rod 38. The third drive mechanism 39 can drive the other end 38b of the second support rod 38 to move (for example, drive the other end 38b of the second support rod 38 to move along the second direction D2), and provide torque to the rotating bracket 36 through the second support rod 38 to drive the rotating bracket 36 to rotate about the second axis X2.

[0122] In this application, the first support rod 37, the second support rod 38 and the third drive mechanism 39 can constitute a tilting drive mechanism, which can drive the rotating bracket 36 to rotate around the second axis X2, thereby tilting the surface of the housing 331 relative to the horizontal plane.

[0123] In some examples, the first support rod 37 may be an elastic support structure (e.g., a gas spring), the second support rod 38 may be a linkage mechanism, and the third drive mechanism 39 may include, for example, a motor, belt, clutch, brake, lead screw mechanism, etc.

[0124] For example, in the third drive mechanism 39, a belt drive can be used to transmit the power of the motor to the lead screw mechanism via a clutch. The lead screw mechanism uses the relative movement of the lead screw and the lead screw nut to achieve the transmission of motion and force. The lead screw nut can be connected to the other end 38b of the second support rod 38, thereby driving the second support rod 38 to move, so that the rotating bracket 36 rotates around the second axis X2. In addition, a brake can stop the rotation of the rotating bracket 36.

[0125] In the above example, the use of a clutch enables the independence of manually driven and electrically driven rotating bracket 36; the brake enables braking at any angle, thereby stopping the rotating bracket 36 at any rotational position; the screw mechanism can be, for example, a multi-start high (large) lead ball screw with no self-locking screw nut, which facilitates manual rotation of the rotating bracket 36, and the operating force is small, and the low noise requirement is met; the first support rod 37 (e.g., a gas spring) is used to balance the gravitational torque on the rotating bracket 36.

[0126] Furthermore, in some examples, the third drive mechanism 39 may not include a motor, thereby allowing the operator to manually drive the rotation of the rotating bracket 36, and the brake can stop the rotation of the rotating bracket 36 and keep it in the stopped position.

[0127] like Figure 8 As shown, in some embodiments, the detection device 300 further includes a fourth drive mechanism 40. The fourth drive mechanism 40 may be disposed on the column 31. The fourth drive mechanism 40 may drive the connecting arm 32 to move along the first direction D1 on the column 31.

[0128] Figure 13 This is a side view of the fourth drive mechanism 40. Figure 14 This is a front view of the fourth drive mechanism 40. Figure 15 This is a partial three-dimensional schematic diagram of the fourth drive mechanism 40. (See attached diagram.) Figure 13 , Figure 14 and Figure 15 As shown, the fourth drive mechanism 40 may include an arm mounting plate 41 and an arm drive device 42.

[0129] One end 32A of the connecting arm 32 can be connected to the arm mounting plate 41, thereby enabling the connecting arm 32 to move along the first direction D1 when the arm mounting plate 41 moves along the first direction D1. The arm drive device 42 can drive the arm mounting plate 41 to move along the first direction D1.

[0130] The arm drive device 42 may include a lead screw. For example, the arm drive device 42 includes: a lead screw 421, a bearing 422, a nut 423, a slide rail 424, and a slider 425.

[0131] The bearing 442 comprises one or more (e.g., two) for supporting the lead screw 421. The lead screw 421 can be connected to the rotating shaft (not shown) of the motor 420. The lead screw 421 can be positioned along a first direction D1. The outer surface of the lead screw 421 has threads. A nut 423 is fitted onto the surface of the lead screw 421, and the inner surface of the nut 423 has threads. The threads on the inner surface of the nut 423 mate with the threads on the outer surface of the lead screw 421. Furthermore, the nut 423 may also contain balls, thus forming a ball screw structure with the nut 423 and the lead screw 421.

[0132] The number of slide rails 424 can be one or more (e.g., two), and the slide rails 424 can be arranged parallel to the lead screw 421. For example, two slide rails 424 can be respectively arranged on both sides of the lead screw 421, thereby improving the stability of the arm mounting plate 41 during movement. The slider 425 is mounted on the surface of the slide rail 424, and the slider 425 slides under the guidance of the slide rail 424.

[0133] like Figure 14 As shown, nut 423 can be connected to arm mounting plate 41, for example, by means of fasteners such as bolts. Slider 425 can also be connected to arm mounting plate 41, for example, by means of fasteners such as bolts.

[0134] exist Figure 13 In the arm drive device 42: when the motor 420 rotates, it drives the lead screw 421 to rotate; through the engagement between the threads of the lead screw 421 and the nut 423, and the guidance of the slide rail 424, the rotation of the lead screw 421 is converted into the movement of the nut 423, the slider 425, and the arm mounting plate 41 along the first direction D1. The change in the rotation direction of the motor 420 can adjust the movement of the nut 423, the slider 425, and the arm mounting plate 41 toward one end or the other end of the first direction.

[0135] Figure 16 This is another side view of the fourth drive mechanism according to an embodiment of this application. Figure 17 yes Figure 16 The corresponding 3D diagram.

[0136] exist Figure 16 and Figure 17 In the example shown, the fourth drive mechanism 40a may include an arm mounting plate 41a and an arm drive device 42a.

[0137] The arm mounting plate 41a can be connected to the connecting arm 32 (e.g., one end 32A of the connecting arm 32), thereby enabling the connecting arm 32 to move along the first direction D1 when the arm mounting plate 41a moves along the first direction D1. The arm drive device 42a can drive the arm mounting plate 41a to move along the first direction D1.

[0138] The arm drive unit 42a can be a belt-based drive mechanism. For example... Figure 15 and Figure 16 As shown, the arm drive device 42a includes: a motor belt drive unit 421a, a belt 422a, and a counterweight 423a.

[0139] The motor belt drive unit 421a includes a motor 4210a, a first wheel 4211a, a second wheel component 4212a, and a third wheel component 4213a. The first wheel 4211a is mounted on the rotating shaft (not shown) of the motor 4210a and rotates with the rotating shaft. The first wheel 4211a transmits the power generated by the rotation of the motor 4210a's rotating shaft to the second wheel component 4212a via a belt or gear mechanism. A belt 422a is disposed on the outer periphery of the second wheel component 4212a and the third wheel component 4213a, thereby driving the belt 422a to move when the second wheel component 4212a rotates. The belt 422a is connected to the arm mounting plate 41a, thereby driving the arm mounting plate 41a to move along a first direction D1 when the belt 422a moves.

[0140] The counterweight 423a and the arm mounting plate 41a can be connected to both ends of the belt 422a, and the counterweight 423a and the arm mounting plate 41a are respectively located on both sides of the second wheel component 4212a. The counterweight 423a enables the belt 422a to be in a tensioned state, so that the movement of the second wheel component 4212a can be transmitted to the belt 422a.

[0141] Furthermore, in this application, the number of belts 422a can be two, which facilitates the stability of the arm mounting plate 41a. This application is not limited to this; the number of belts 422a can also be other, such as one or three.

[0142] In this application, the third wheel component 4213a is disposed on one side of the second wheel component 4212a along the second direction D2. Thus, the third wheel component 4213a supports the belt 422a, ensuring that the position of the belt 422a meets the requirements of the internal space of the column 31. In other examples of this application, when there are other requirements for the internal space of the column 31, the third wheel component 4213a may not be provided, or additional wheel components may be provided in addition to the third wheel component 4213a.

[0143] like Figure 16 and Figure 17 As shown, the fourth drive mechanism 40a may also have a control circuit board 43a. The control circuit board 43a can control the rotation direction of the motor in the motor belt drive unit 421a, thereby adjusting the movement direction or position of the arm mounting plate 41a.

[0144] In this application, the connecting arm 32 can move along a first direction D1, thereby adjusting the position of the connecting arm 32 in the first direction D1. The housing 331 can rotate about a first axis X1, thereby adjusting the relationship between the length direction L of the housing 331 and the horizontal direction. The housing 331 can also tilt, thereby adjusting the tilt angle of the surface of the housing 331 relative to the horizontal plane. Inside the housing 331, the detector 332 can move along the length direction L. Thus, the position and orientation of the housing 331 of the detection device 300 can be flexibly adjusted to suit different inspection needs.

[0145] Figure 18 This is another perspective view of the detection device according to an embodiment of this application. Figure 19 This is yet another perspective view of the detection device according to an embodiment of this application. Figure 18 In the middle, the length direction L of the housing 331 is parallel to the horizontal direction, and the surface of the housing 331 is perpendicular to the second direction D2. Figure 19 In the case of housing 331, the length direction L is parallel to the horizontal direction, and the surface of housing 331 is perpendicular to the first direction D1. Furthermore, in... Figure 3In the example shown, the length direction L of the housing 331 is parallel to the vertical direction, and the surface of the housing 331 is perpendicular to the second direction D2. Figure 3 , Figure 18 , Figure 19 In this configuration, detector 332 can move along the length direction L inside the housing 331.

[0146] Figure 20 This is a schematic diagram illustrating a medical imaging examination using the detection device according to an embodiment of this application. Figure 20 In this embodiment, the medical imaging system 2000 may include the detection device 300 and the suspension device 2003 described above.

[0147] In this configuration, the detection device 300 is adjusted such that the length direction L of the housing 331 is parallel to the horizontal direction, and the surface of the housing 331 is perpendicular to the first direction D1. The housing 331 can be positioned below the movable bed 2001 in the first direction D1. The suspension device 2003 irradiates the object 2002 on the movable bed 2001 with X-rays. The detector 332 inside the housing 331 receives the X-rays passing through the object 2002, thereby forming a medical image.

[0148] exist Figure 20 In this configuration, the detector 332 can move along the length direction L inside the housing 331. For example, the detector 332 can acquire corresponding medical images at different positions along the length direction L of the housing 331. Thus, without moving the object 2002 being tested, corresponding medical images can be acquired for different parts of the object 2002 being tested.

[0149] In addition, Figure 20 In the example shown, multiple medical images obtained by the detector 332 at different positions along the length L of the housing 331 can be synthesized to form a complete medical image containing different parts of the object being tested 2002.

[0150] Furthermore, for the description of the suspension device 2003, please refer to the aforementioned description. Figure 1 The suspension device 110 and Figure 2 Description of suspension device 26.

[0151] According to the above embodiments of this application, in the detection device 300, the housing 331 is connected to the column 31 via the connecting arm 32, the detector 332 is disposed in the housing 331, and a first driving mechanism 333 is provided to drive the detector 332 to move within the housing 331. Thus, the detector 332 can move relative to the connecting arm 32, and the height of the column 31 can be reduced (for example, the height of the column 31 can be reduced from 2300mm to 1600mm), which facilitates the transportation and installation of the column 32, reduces the requirements for the indoor space of the scanning room, and the housing 331 itself can play a shielding role. Therefore, during inspection, the operator does not need to set up special shielding components, thus simplifying the inspection process.

[0152] Furthermore, in various embodiments of this application, the connecting arm 32 may be made of aluminum alloy, thereby reducing weight while maintaining strength.

[0153] Furthermore, in various embodiments of this application, the housing 331 may be made of plastic or carbon fiber material to reduce weight, thereby facilitating user operation to adjust the position or tilt angle, etc.

[0154] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0155] The present application has been described above with reference to specific embodiments. However, those skilled in the art should understand that these descriptions are exemplary and not intended to limit the scope of protection of the present application. Those skilled in the art can make various modifications and variations to the present application based on the principles thereof, and these modifications and variations are also within the scope of the present application.
