Fig. 1 is a schematic diagram of an X-ray imaging system according to an embodiment of the application. As shown in FIG. 1, an X-ray imaging system 100 may be an example of a medical imaging system that includes a suspension apparatus 110 disposed in a scanning room 101, a column (WALL STAND) apparatus 120, and a couch apparatus 130, and a control apparatus 150 disposed within a control room 102. The suspension device 110 includes a longitudinal rail 111, a transverse rail 112, a telescopic cylinder 113, a sled 114, and a bulb assembly 115.

Although some embodiments of the present application are described based on an overhead X-ray imaging system, embodiments of the present application are not so limited. For example, the medical imaging system may also be other types of X-ray imaging systems, or the medical imaging system may also be other types of imaging systems, such as, for example, electronic Computer Tomography (CT) systems, positron Emission Tomography (PET) systems, magnetic Resonance Imaging (MRI) systems, etc.

For convenience of description, in the present application, the x-axis, the y-axis, and the z-axis are defined as being in a horizontal plane and perpendicular to each other, and the z-axis is perpendicular to the horizontal plane, specifically, the direction in which the longitudinal rail 111 is located is defined as the x-axis, the direction in which the lateral rail 112 is located is defined as the y-axis direction, the extension direction of the telescopic tube 113 is defined as the z-axis direction, and the z-axis direction is the vertical direction.

The longitudinal rail 111 and the transverse rail 112 are vertically arranged, wherein the longitudinal rail 111 is mounted on the ceiling and the transverse rail 112 is mounted on the longitudinal rail 111. Telescoping barrel 113 is used to carry bulb assembly 115.

The pulley 114 is disposed between the transverse guide rail 112 and the telescopic cylinder 113, and the pulley 114 may include a rotating shaft, a motor, a winding drum, and the like, and the motor can drive the winding drum to rotate around the rotating shaft, so as to drive the telescopic cylinder 113 to move along the z-axis and/or slide relative to the transverse guide rail. The sled 114 is capable of sliding relative to the cross rail 112, i.e., the sled 114 is capable of moving the telescoping tube 113 and/or the bulb assembly 115 in the y-axis direction. And the transverse guide rail 112 can slide relative to the longitudinal guide rail 111, so as to drive the telescopic cylinder 113 and/or the bulb assembly 115 to move along the x-axis direction.

The telescopic cylinder 113 comprises a plurality of cylinders with different inner diameters, and the cylinders can be sleeved in the cylinders on the telescopic cylinder from bottom to top in sequence to realize telescopic operation, and the telescopic cylinder 113 can be telescopic (or movable) in the vertical direction, namely, the telescopic cylinder 113 can drive the bulb assembly to move along the z-axis direction. The lower end of the telescopic cylinder 113 is further provided with a rotating part which can rotate the bulb assembly 115.

The bulb assembly 115 includes an X-ray tube that can generate X-rays and project the X-rays toward a desired region of interest ROI of a patient. In particular, the X-ray tube may be positioned adjacent to a beam limiter for aligning the X-rays to an intended region of interest of the patient. At least a portion of the X-rays may be attenuated by the patient and may be incident upon the detector 121/131.

The suspension apparatus 110 further includes a beam limiter 117, and the beam limiter 117 is generally mounted below the X-ray tube, and X-rays emitted from the X-ray tube are irradiated onto the subject through an opening of the beam limiter 117. The size of the opening of the beam limiter 117 determines the irradiation range of the X-rays, that is, the area size of the exposure Field of View (FOV). The position of the X-ray tube and beam limiter 117 in the lateral direction determines the position of the exposure field FOV on the subject. It is well known that X-rays are harmful to the human body, and thus it is necessary to control the X-rays to irradiate only the region to be examined, i.e., the region of interest (Region of Interest, ROI), of the object to be examined.

The suspension apparatus 110 further includes a bulb control apparatus (bulb) 116, and the bulb control apparatus 116 is mounted on the bulb assembly, and the bulb control apparatus 116 includes a display screen, control buttons, and other user interfaces for performing preparation work before photographing, such as patient selection, protocol selection, and positioning.

The movements of the suspension 110 include movements of the bulb assembly along the x, y and z axes, and rotations of the bulb assembly in the horizontal plane (with the axis of rotation parallel or coincident with the z axis) and in the vertical plane (with the axis of rotation parallel to the y axis), in which movements the respective components are typically rotated by motor-driven shafts to effect the respective movements or rotations, and the respective control components are generally mounted within the sled 114. The X-ray imaging unit further comprises a motion control unit (not shown in the figures) capable of controlling the above-mentioned movement of the suspension 110, and further, capable of receiving control signals to control the respective components to move accordingly.

Column assembly 120 includes a first detector assembly 121, column 122, and connection 123. The connection part 123 includes a support arm vertically connected to the height direction of the upright 122 and a rotating bracket mounted on the support arm, the first probe assembly 121 is mounted on the rotating bracket, the upright device 120 further includes a probe driving device disposed between the rotating bracket and the first probe assembly 121, and the first probe assembly 121 is further rotatable relative to the support arm to form an angle with the upright by being driven by the probe driving device to move in a direction parallel to the height direction of the upright 122 on a plane lifted by the rotating bracket. The first detector assembly 121 has a plate-like structure whose direction is changeable so as to make the X-ray incident surface vertical or horizontal according to the incident direction of the X-rays.

The second detector assembly 131 is included on the detection bed device 130, and the selection or use of the first detector assembly 121 and the second detector assembly 131 can be determined based on the shooting position and/or the shooting protocol of the patient, and can also be determined based on the position of the detected object obtained by shooting with a camera, so as to perform shooting inspection of the lying position or the standing position. Fig. 1 shows only one example of a column and a test bed, and it should be understood by those skilled in the art that any form or arrangement of columns and/or test beds may be selected and installed, and that the columns and/or test beds are not limiting to the overall solution of the present application.

In some embodiments, the medical imaging system includes an imaging device 140 (e.g., a camera) by which the subject can be imaged to obtain a captured image containing the subject, such as a still optical image or a series of frame optical images in a dynamic real-time video stream, for auxiliary positioning and exposure settings, and so forth. The image pickup device may be mounted on a suspension device, for example, on a side of the beam limiter 117, etc., and the embodiment of the present application is not limited thereto. The camera 140 includes one or more cameras, such as digital cameras, analog cameras, etc., or depth cameras, infrared cameras, or ultraviolet cameras, etc., or 3D cameras, 3D scanners, etc., or Red Green Blue (RGB) sensors, RGB depth (RGB-D) sensors, or other devices that can capture color image data of a target object.

In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller is used for commanding the X-ray source to emit X-rays for image exposure. The detector controller is used to select an appropriate detector among a plurality of detectors and coordinate control of various detector functions, for example, to automatically select a corresponding detector according to the position or posture of a detected object, or to perform various signal processing and filtering functions, in particular, initial adjustment of a dynamic range, interleaving of digital image data, and the like. In some embodiments, the control device may provide power and timing signals for controlling the operation of the X-ray source and detector.

In some embodiments, the control device may also be configured to reconstruct one or more desired images and/or determine useful diagnostic information corresponding to the patient using the digitized signals, wherein the control device may include one or more special purpose processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs), or other suitable processing devices.

Of course, the medical imaging system may also include other numbers or configurations or forms of control devices, e.g., the control devices may be local (e.g., co-located with one or more X-ray imaging systems 100, e.g., within the same facility and/or the same local network); in other implementations, the control device may be remote and therefore only accessible via a remote connection (e.g., via the internet or other available remote access technology). In particular implementations, the control device may also be configured in a cloud-like manner and may be accessed and/or used in a manner substantially similar to the manner in which other cloud-based systems are accessed and used.

The system 100 also includes a memory device (not shown) in which the processor can store the digitized signals. For example, the memory may include a hard disk drive, a floppy disk drive, an optical disk read/write drive, a digital versatile disk drive, a flash memory drive, and/or solid state memory. The memory may also be integrated with the processor to efficiently use the footprint and/or to meet desired imaging requirements.

The system 100 further comprises input means 160, which input means 160 may comprise some form of operator interface such as a keyboard, a mouse, voice activated control means, a touch screen (which may also be referred to as a display means as described below), a trackball or any other suitable input device by which an operator may input operation/control signals to the control means.

The system 100 further comprises a display device 151 (e.g. a touch screen or display screen), which display device 151 may be used to display a list of detected objects, a positioning or exposure setting of detected objects, an image of detected objects, etc. an operation interface.

In the examining table apparatus 130, the second detector assembly 131 may include a tray, not shown, in which the detector may be carried, a holding frame, and a detector, which may be used to carry the tray. The operator can withdraw the tray from the holding frame or insert the tray into the holding frame. On the tray or the holding frame, there may be provided several operating units (e.g. control buttons, etc.) by means of which an operator can control the medical imaging system.

In some techniques, the operating unit is provided on the tray, and moves together with the tray, so that a flexible connection structure (e.g., an electrical connection wire, a drag chain, etc.) needs to be provided between the operating unit and the holding frame, and thus the cost is high.

In other techniques, the operation unit is fixedly mounted on the support frame, and although cabling such as cables is omitted, when an operator pushes the tray into the support frame, the operator's finger or foreign matter may be caught between the edge of the tray and the support frame, causing damage to the operator or equipment.

To address the above-identified problems, or at least similar problems, embodiments of the present application provide a table assembly and a medical imaging system.

The following describes embodiments of the present application in detail.

The embodiment of the application provides a workbench assembly.

Fig. 2 is a perspective view of a table assembly according to an embodiment of the present application, fig. 3 is a perspective view of a portion indicated by an arrow a in fig. 2, fig. 4 is a cross-sectional view seen in an X-X direction of fig. 3, fig. 5 is a side view seen in a second direction of fig. 3, fig. 6 is a schematic view of a locked state of a tray and a holding frame, and fig. 7 is a schematic view of a foreign matter between the tray and a floating member.

As shown in fig. 2 and 3, the table assembly 200 includes: a body 201, a holding frame 202, a tray 203, a floating member 204, and an operation unit 205.

In the following description of the present application, the first direction D1, the second direction D2, and the third direction D3 may be perpendicular to each other. For example, the first direction D1 may be a width direction of the body 201, the second direction D2 may be a length direction of the body 201, and the third direction D3 may be a height direction of the body 201. Further, in one example, the first direction D1 and the second direction D2 may be parallel to the horizontal direction, and the third direction D3 may be along the vertical direction.

As shown in fig. 2 and 3, in some embodiments, the table assembly 200 is, for example, a test bed of a medical imaging system.

The body 201 of the table assembly 200 may include a support frame 2011, a bed panel assembly 2012, a lift assembly (not shown), and the like. The support frame 2011 is mounted on a lifting assembly, the bed panel assembly 2012 is mounted on the support frame 2011, and the lifting assembly can be controlled to move to drive the support frame 2011 and the bed panel assembly 2012 to lift, so that the body 201 or the workbench assembly 200 can be lifted. A receiving space 2013 may be formed between the support frame 2011 and the deck panel assembly 2012. The receiving space 2013 may be used to receive the holding frame 202 and the tray 203.

The holding frame 202 may be mounted to the body 201. For example, the racking frame 202 can be movably mounted to the body 201, more specifically, the racking frame 202 is mounted on the support frame 2011, and the racking frame 202 is placed in the receiving space 2013. The support frame 202 can be fixed relative to the body 201 in a locked state; the holding frame 202 is movable in the second direction D2 with respect to the body 201 in the unlocked state. In some embodiments, the support frame 202 may be movably mounted to the body 201 by means of a rail or the like.

As shown in fig. 2, the support frame 202 may be a frame formed by splicing four side frames 202a, 202b, 202c, 202D, for example, the side frames 202a and 202c may be parallel to the second direction D2, and the side frames 202b and 202D may be parallel to the first direction D1.

As shown in fig. 2 and 3, the frame 202a may have a side plate 2021 for mounting the floating member 204, for example, in the second direction D2, the side plate 2021 may be located outside the floating member 204. In addition, the frame 202a may further have a fixing portion 2022 (as shown in fig. 3), the fixing portion 2022 may be closer to the frame 202c side than the side plate 2021, and the fixing portion 2022 may extend along the second direction D2. In one example shown in fig. 3, the side plate 2021 and the fixing portion 2022 may be integrally connected.

The tray 203 is movably mounted to the holding frame 202. The tray 203 can be fixed to the holding frame 202 in a locked state, for example, both the holding frame 202 and the tray 203 are disposed in the accommodation space 2013; the tray 203 is movable in the first direction D1 with respect to the holding frame 202 in an unlocked state. In some embodiments, the tray 203 may be movably mounted to the support frame 202 by means of a rail or the like.

The tray 203 may be used to carry a detector of a medical imaging system. For example, an operator may withdraw the tray 203 from the holding frame 202 in the first direction D1, mount the detector on the tray 203 or remove the detector carried on the tray 203, and then the operator may push the tray 203 into the holding frame 202 in the first direction D1.

The tray 203 may have a plate shape with an outer edge 2031 (as shown in fig. 2) extending downward, for example, the outer edge 2031 may be located outside the frame 202a in the first direction D1, and the outer edge 2031 may cover the frame 202a and the floating member 204 from outside the first direction D1 when the tray 203 is pushed into the holding frame 202.

The float member 204 is movably mounted to the holding frame 202. At least a portion of the float member 204 is capable of displacement in a first direction D1. The floating member 204 may be installed at the bottom of the holding frame 202, for example, the floating member 204 is installed on one frame 202a of the holding frame 202 near the direction in which the tray 203 is pulled out.

The operation unit 205 is provided to the floating member 204. The operation unit 205 receives an operation to control the movement or fixation of the holding frame 202 with respect to the body 201. The table assembly 200 may have a first stopper 206, where the first stopper 206 is mounted to the body 201 or the support frame 202, and the first stopper 206 can lock the support frame 202 such that the support frame 202 is in a locked state, and the support frame 202 is fixed with respect to the body 201, i.e., the support frame 202 does not move with respect to the body 201.

In some examples, as shown in fig. 6, in a state where the tray 203 is locked with the holding frame 202, an operator (e.g., a finger 600 of the operator) may operate the operation unit 205, unlock the holding frame 202 from the body 201, and operate the tray 203 and the holding frame 202 together to move D2 in a second direction with respect to the body 201, so that the detector moves to a corresponding position of a predetermined body part of the subject to be detected. Further, if the operator stops operating the operation unit 205, the first stopper 206 brings the holding frame 202 into a locked state, thereby fixing the position of the holding frame 202 with respect to the body 201.

In other examples, as shown in fig. 7, in the case where a foreign object 700 (e.g., a body part such as a finger of an operator or other foreign object) is caught between the tray 203 and the floating member 204 during the pushing of the tray 203 into the holding frame 202, the force exerted on the finger or other foreign object by the tray 203 can be buffered by the displacement of at least a portion of the floating member 204 in the first direction D1, thereby avoiding damage to the person or apparatus. Further, since the operation unit 205 is provided to the floating member 204, it is possible to avoid providing a flexible connection structure (for example, an electrical connection line, a drag chain, or the like) between the operation unit 205 and the holding frame 202, and thus it is possible to reduce the cost.

As shown in fig. 3, the float member 204 is pivotally mounted to the holding frame 202.

In some embodiments, table assembly 200 has a shaft 207, and shaft 207 may extend along a second direction D2 that is perpendicular to first direction D1.

As shown in fig. 3, the shaft 207 is mounted to the support frame 202. For example, the shaft 207 is mounted to a side plate 2021 of the support frame 202.

The shaft 207 may pass through the mounting hole 2041 of the float member 204, whereby the float member 204 can rotate about the central axis C (shown in fig. 5) of the shaft 207, so that the float member 204 can be pivotally mounted to the holding frame 202.

The floating member 204 generates displacement in the first direction D1 by rotating about the center axis C. Further, the present application is not limited thereto, and the floating member 204 may be displaced in the first direction D1 by other structures.

As shown in fig. 3 and 4, the table assembly also includes an elastic member 208. The elastic member 208 abuts against the floating member 204, thereby providing the floating member 204 with torque that rotates in the first direction D1 toward the outer edge portion 2031 near the tray 203. Thereby, in the case where foreign matter between the tray 203 and the floating member 204 is removed, the floating member 204 can be returned to the normal position.

For example, the elastic member 208 is a torsion spring, wherein one torsion arm 2081 of the torsion spring abuts against the fixing portion 2022 of the support frame 202, and the other torsion arm 2082 of the torsion spring is accommodated in the accommodating groove 2042 of the floating member 204. Thereby, in the case where foreign matter between the tray 203 and the floating member 204 is removed, the torsion spring can provide torque to return the floating member 204 to the normal position.

As shown in fig. 3, the side plate 2021 may be located on at least one side of the floating member 204 in the second direction D2, for example, the side plate 2021 may have two pieces, and the floating member 204 is located between the two side plates 2021 in the second direction D2.

As shown in fig. 3, 4 and 5, the side plate 2021 may have a limiting groove 2023, a surface 204a of the floating member 204 facing the side plate 2021 (as shown in fig. 5) may have a limiting protrusion 2043, the limiting protrusion 2043 may protrude in the second direction, and at least a portion of the limiting protrusion 2043 may be accommodated in the limiting groove 2023.

As shown in fig. 5, the limiting groove 2023 has a first end 2024 and a second end 2025. Wherein the first end 2024 is closer to the outer edge 2031 of the tray 203 than the second end 2025 in the first direction D1.

The limit groove 2023 and the limit projection 2043 can define a rotation range of the floating member 204. For example, as shown in fig. 5, when there is a foreign matter between the tray 203 and the floating member 204 to cause the floating member 204 to rotate in the counterclockwise direction, the stopper projection 2043 is blocked by the second end 2025, thereby preventing the floating member 204 from being lifted too high to contact the tray 203; as another example, as shown in fig. 5, when the float member 204 rotates in the clockwise direction, the stopper projection 2043 is stopped by the first end 2024, thereby separating the tray 203 from the float member 204 during the process that the tray 203 is pulled out.

As shown in fig. 4, the floating member 204 may be polygonal when viewed in the second direction D2. Further, the dimension (e.g., height) of the floating member 204 in the third direction D3 varies along the first direction D1, for example, the closer to the position where the operation unit 205 is provided, the larger the dimension in the third direction D3.

In some embodiments, the float member 204 has a first surface 2044, an inner wall 2032 of an outer edge portion 2031 of the tray 203 abuts against the first surface 2044 in a state where the tray 203 is locked with the holding frame 202, and a stopper projection 2043 of the float member 204 is located in a position not in contact with both the first end portion 2024 and the second end portion 2025 within the stopper groove 2023. Thus, when the operator operates the operation unit 205, the force applied by the operator to the operation unit 205 can be transmitted to the tray 203 through the floating member 204. In contrast, if the size of the floating member 204 in the first direction D1 is small, resulting in that the first surface 2044 does not abut against the inner wall 2032 of the outer edge portion 2031 of the tray 203, but the stopper projection 2043 abuts against the first end portion 2024 within the stopper groove 2023, then the force applied by the operator to the operation unit 205 will act on the stopper projection 2043, easily causing damage to the stopper projection 2043.

In at least some embodiments, as shown in fig. 4, the float member 204 further has a second surface 2045 and a bottom surface 2046, wherein the bottom surface 2046 and the second surface 2045 are connected to two ends of the first surface 2044, respectively.

The second surface 2045 is inclined with respect to the first surface 2044, for example, the closer to the first surface 2044 in the first direction D1, the closer the second surface 2045 is to the bottom surface 2046 in the third direction D3 (as shown in fig. 5) in a state where the inner wall 2032 of the outer edge portion 2031 of the tray 203 abuts against the first surface 2044 of the floating member 204. Wherein the third direction D3 is perpendicular to both the first direction D1 and the second direction D2.

As shown in fig. 4, the floating member 204 further has a fourth surface 2047, the fourth surface 2047 being disposed opposite to the first surface 2044, and the operation unit 205 is disposed on the fourth surface 2047 of the floating member 204, whereby the operation unit 205 can be operated by an operator by bending a finger.

In addition, when a foreign object is present between the tray 203 and the floating member 204, at least a part of the floating member 204 can be displaced in the first direction D1, and the operation unit 205 is lifted up to be in a state where it is not easy to be touched and operated, so that an operator can determine whether or not a foreign object is present between the tray 203 and the floating member 204 by checking the position of the operation unit 205.
