Technical Field

[0073] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0074] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0075] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). The front-back, left-right, and up-down directions in this document are mutually perpendicular, with the up-down direction being vertical and the front-back and left-right directions being horizontal.

[0076] In one embodiment, an X-ray imaging system is provided with an examination bed. This examination bed is used for X-ray imaging of patients in supine, lateral, or other positions to detect lesions. A flat panel detector can be installed below the examination bed. This flat panel detector is mainly used for X-ray imaging of supine patients. An X-ray generating device emits X-rays from above the examination bed from top to bottom. The X-rays pass through the patient and the support platform in sequence and irradiate the flat panel detector below the support platform. The flat panel detector collects the X-rays passing through the patient and generates corresponding detection signals. These detection signals are used to obtain the X-ray image of the patient.

[0077] In this embodiment, an electric motion device is provided under the support platform of the testing bed. The electric motion device can electrically drive the flat panel detector under the support platform to move along the left and right and front and back directions of the testing bed. The flat panel detector has a larger range of movement, especially the ability to move in the front and back direction. For patients with a wider body size, by electrically driving the flat panel detector to move in the front and back direction, the patient does not need to move his body, which can realize multiple exposure imaging, has higher shooting efficiency, and provides patients with a better shooting experience.

[0078] Please refer to Figures 1 to 4 In this embodiment, the X-ray imaging system's inspection bed mainly includes a base 1, a support platform 2, an electric motion device 3, and a mounting component 4.

[0079] Base 1 can be a fixed base with a fixed height to meet the needs of most users. Alternatively, base 1 can be a height-adjustable base, allowing adjustment of the testing bed's height to suit different user needs.

[0080] The base 1 serves as the support component for the testing bed. The support platform 2 is mounted on top of the base 1, fixing or raising / lowering the support platform 2 to a preset height. The support platform 2 can be a rectangular bed board structure. The upper surface of the support platform 2 is a support surface 21, used to support the patient. The support surface 21 is rectangular, allowing the patient to lie flat on it. The support surface 21 has a length direction and a width direction. The length of the support surface 21 in the left-right direction is greater than its length in the front-back direction. The left-right direction of the support surface 21 is parallel to its length direction, and the front-back direction is parallel to its width direction. Specifically, the left-right direction of the support surface 21 corresponds to the left-right direction of the testing bed, and the front-back direction also corresponds to the front-back direction of the testing bed.

[0081] In other embodiments, the supporting platform 2 may also be a concave arc shape or other structure. In this case, the supporting surface 21 of the supporting platform 2 is a concave arc surface, and the four sides of the supporting surface 21 include two long sides and two arc-shaped short sides. The left-right direction of the supporting surface 21 is parallel to the two long sides of the supporting surface 21, and the width direction of the supporting surface 21 is parallel to the line connecting the two endpoints of the arc-shaped short sides. That is, the supporting surface 21 can be any other irregular structure, which also has corresponding left-right and front-back directions.

[0082] In this embodiment, the electric motion device 3 is installed on the upper end of the base 1 and located below the support platform 2. The mounting component 4 is installed on the electric motion device 3 and is also located below the support platform 2. The mounting component 4 is used for detachable installation on the flat panel detector 7. The electric motion device 3 is used to electrically drive the mounting component 4 and the flat panel detector 7 mounted on the mounting component 4 to move along the left-right and front-back directions of the detection bed, so that the flat panel detector 7 can move below different areas of the support surface 21 to achieve imaging of different parts of the patient.

[0083] In this embodiment, an operating component is provided on the side of the testing bed or on other equipment outside the testing bed. The operating component can be a button, touch screen, or other operating parts. The operating component is electrically connected to the electric motion device 3 via a controller 9. The doctor can use the operating component to control the electric motion device 3 to electrically drive the mounting component 4 and the flat panel detector 7 to move along the left-right and front-back directions of the testing bed. The controller 9 can be installed inside the testing bed or outside the testing bed, for example, the controller 9 can be installed inside the host computer.

[0084] The electric motion device 3 mainly includes an electric drive component 31, a first motion component 32, and a second motion component 33. The electric drive component 31 is an electric drive device used to output power. The first motion component 32 and the second motion component 33 are motion structures used to guide the movement of the mounting component 4. The electric drive component 31 is mounted on the base 1, the first motion component 32 is mounted on the upper end of the base 1, the second motion component 33 is mounted on the first motion component 32, and the mounting component 4 is mounted on the second motion component 33. The first motion component 32 will simultaneously drive the second motion component 33 and the mounting component 4 to move along the first direction of the testing bed, and the second motion component 33 will drive the mounting component 4 to move along the second direction of the testing bed.

[0085] The first direction is one of the left-right and front-back directions of the testing bed, and the second direction is the other of the left-right and front-back directions of the testing bed. That is, the first motion component 32 can be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along one of the left-right or front-back directions of the testing bed, and the second motion component 33 can be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along the other of the left-right or front-back directions of the testing bed.

[0086] In this embodiment, the first motion component 32 can be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along the left and right directions of the testing bed, and the second motion component 33 can be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along the front and back directions of the testing bed. Since the left and right length of the testing bed is greater than the front and back length, the stroke of the first motion component 32 is greater than the stroke of the second motion component 33, that is, the overall volume and weight of the first motion component 32 are greater than those of the second motion component 33. By placing the first motion component 32, which is used to drive the left and right movement, below, and the second motion component 33, which is used to drive the front and back movement, above, that is, placing the relatively larger and heavier first motion component 32 below and the relatively smaller and heavier second motion component 33 above, the load on the lower first motion component 32 can be reduced, the driving power required by the first motion component 32 can be reduced, and thus the movement accuracy of the first motion component 32 can be improved.

[0087] In other embodiments, the first motion component 32 can also be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along the front-back direction of the testing bed, and the second motion component 33 can be used to electrically drive the mounting component 4 and the flat panel detector 7 to move along the left-right direction of the testing bed, and can also realize the electric drive of the mounting component 4 and the flat panel detector 7 to move along the front-back direction and the left-right direction of the testing bed.

[0088] In this embodiment, the electric drive unit 31 includes a first electric drive unit 311 and a second electric drive unit 312. The first electric drive unit 311 is connected to the first motion component 32. The first electric drive unit 311 is used to electrically drive the mounting component 4 and the flat panel detector 7 to move along a first direction through the first motion component 32. The second electric drive unit 312 is used to electrically drive the mounting component 4 and the flat panel detector 7 to move along a second direction through the second motion component 33.

[0089] The electric drive unit 31 includes two power drive devices, with two power sources driving the mounting component 4 and the flat panel detector 7 to move in different directions. This configuration simplifies the transmission scheme, and the first electric drive unit 311 and the second electric drive unit 312 can be controlled relatively independently. The flat panel detector 7 has higher movement accuracy when moving in the first and second directions respectively. The two power drive devices can also achieve synchronous or asynchronous movement of the first motion component 32 and the second motion component 33, thereby enabling the electric drive of the mounting component 4 and the flat panel detector 7 to move synchronously or asynchronously in the left-right and front-back directions of the detection bed.

[0090] In other embodiments, the electric drive unit 31 may also include only one power source, which is connected to the first motion component 32 and the second motion component 33 through two different transmission components, and may also electrically drive the first motion component 32 and the second motion component 33 to move synchronously or asynchronously.

[0091] In this embodiment, the first motion component 32 includes a first guide 321 and a first motion component 322. The first guide 321 is mounted on the upper end of the base 1 and is arranged along a first direction (the left-right direction of the testing bed). The first motion component 322 is movably mounted on the upper end of the first guide 321. A first electric drive component 311 is connected to the first motion component 322 and is used to electrically drive the first motion component 322 to move along the first direction.

[0092] Specifically, the first guide member 321 may include two parallel first guide rails 3211. The length direction of the first guide rails 3211 is parallel to the first direction (the left-right direction of the testing bed). The two parallel first guide rails 3211 can be mounted on a first mounting plate 3212. The first mounting plate 3212 is horizontally mounted on the upper end of the base 1, so that the two parallel first guide rails 3211 are laid parallel on a horizontal plane. The setting of the first mounting plate 3212 can ensure the horizontality of the first moving component 32 moving along the first direction. The first mounting plate 3212 can also be part of the base 1, with the two first guide rails 3211 of the first guide member 321 directly mounted on the first mounting plate 3212 of the base 1.

[0093] The first moving component 322 can be a flat plate or a support frame, etc. The lower end of the first moving component 322 is provided with a slider that is adapted to and connected to the first guide rail 3211. The first moving component 322 can slide along the first guide rail 3211 through the slider. The first moving component 322 is set as a flat plate or a support frame, etc., so that the upper end of the first moving component 322 can be used to install the second moving component 33.

[0094] The first electric drive component 311 can be an electric drive device such as a motor. The electric motion device 3 also includes a first transmission component 34, which can include two first synchronous pulleys 341 and a first conveyor belt 342. One of the first synchronous pulleys 341 is mounted on the output shaft of the motor, and the other first synchronous pulley 341 is mounted on the first mounting plate 3212 or the base 1. The first conveyor belt 342 is mounted on the two first synchronous pulleys 341. The line connecting the two first synchronous pulleys 341 is parallel to the first guide rail 3211, so that the first conveyor belt 342 is driven along the first direction. The first motion component 322 is fixedly connected to the first conveyor belt 342. The motor sequentially drives the first conveyor belt 342 to move forward or backward along the first direction through the first synchronous pulleys 341, thereby driving the first motion component 322 to move forward or backward along the first guide rail 3211, and finally driving the second motion component 33, the mounting component 4, and the flat panel detector 7 to move along the left and right directions of the detection bed.

[0095] In other embodiments, the first transmission component 34 may also be other transmission structures, such as a sprocket and chain assembly, a worm gear assembly, a gear assembly, etc. The motor can also electrically drive the second motion component 33, the mounting component 4, and the flat plate detector 7 to move along the left and right directions of the detection bed through the sprocket and chain assembly, the worm gear assembly, the gear assembly, etc.

[0096] In other embodiments, the first electric drive unit 311 can also be other electric drive devices, such as a cylinder or a linear motor. The cylinder or linear motor can be directly connected to the first moving member 322 without the need for the first transmission member 34. The cylinder or linear motor can directly output a linear pair, which can electrically drive the second moving component 33, the mounting member 4, and the flat panel detector 7 to move in the left and right directions of the detection bed.

[0097] In this embodiment, the second motion component 33 includes a second guide 331 and a second motion component 332. The second guide 331 is mounted on the upper end of the first motion component 322 and is arranged along a second direction (the front-rear direction of the testing bed). The second motion component 332 is movably mounted on the upper end of the second guide 331. A second electric drive component 312 is connected to the second motion component 332 and is used to electrically drive the second motion component 332 to move along the second direction.

[0098] Specifically, the second guide member 331 may include two parallel second guide rails 3311. The length direction of the second guide rails 3311 is parallel to the second direction (the front-rear direction of the inspection bed). The two parallel second guide rails 3311 can be mounted on a second mounting plate 3312. The second mounting plate 3312 is horizontally mounted on the upper end of the first moving member 322, so that the two parallel second guide rails 3311 are laid parallel on a horizontal plane. The setting of the second mounting plate 3312 can ensure the horizontality of the second moving component 33 moving along the second direction. The second mounting plate 3312 can also be part of the first moving member 322, with the two second guide rails 3311 of the second guide member 331 directly mounted on the second mounting plate 3312 of the first moving member 322.

[0099] The second moving part 332 can be a flat plate or a support frame, etc. The lower end of the second moving part 332 is provided with a slider that is adapted to and connected to the second guide rail 3311. The second moving part 332 can slide along the second guide rail 3311 through the slider. The second moving part 332 is set as a flat plate or a support frame, etc., so that the upper end of the second moving part 332 can be used to install the mounting part 4. The mounting part 4 can be fixedly installed on the upper end of the second moving part 332 by means of screw connection, welding, snap-fit, etc.

[0100] The second electric drive component 312 can be an electric drive device such as a motor. The electric motion device 3 also includes a second transmission component 35, which can include two second synchronous pulleys 351 and a second conveyor belt 352. One second synchronous pulley 351 is mounted on the output shaft of the motor, and the other second synchronous pulley 351 is mounted on the second mounting plate 3312. The second conveyor belt 352 is mounted on the two second synchronous pulleys 351. The line connecting the two second synchronous pulleys 351 is parallel to the second guide rail 3311, so that the second conveyor belt 352 drives the transmission along the second direction. The second motion component 332 is fixedly connected to the second conveyor belt 352. The motor sequentially drives the second conveyor belt 352 to move forward or backward along the second direction through the second synchronous pulleys 351, thereby driving the second motion component 332 to move forward or backward along the second guide rail 3311, and finally driving the mounting component 4 and the flat panel detector 7 to move along the front-back direction of the detection bed.

[0101] In this embodiment, both the first guide rail 3211 and the second guide rail 3311 include two rails, which can provide more stable translational transmission. In other embodiments, the first guide rail 3211 and the second guide rail 3311 may also include one or three rails, or other numbers of rails, and translational transmission can also be achieved.

[0102] In other embodiments, the second transmission component 35 may also be other transmission structures, such as a sprocket and chain assembly, a worm gear assembly, a gear assembly, etc. The motor can also electrically drive the second motion component 33, the mounting component 4, and the flat plate detector 7 to move along the front and rear direction of the detection bed through the sprocket and chain assembly, the worm gear assembly, the gear assembly, etc.

[0103] In other embodiments, the second electric drive unit 312 can also be other electric drive devices, such as a cylinder or a linear motor. The cylinder or linear motor can be directly connected to the second moving member 332 without the need for a second transmission member 35. The cylinder or linear motor can directly output a linear pair, which can electrically drive the mounting member 4 and the flat plate detector 7 to move in the left and right directions of the detection bed.

[0104] In this embodiment, the electric motion device 3 of the detection bed includes an electric drive unit 31, a first motion component 32, and a second motion component 33. The electric drive unit 31 can drive the flat panel detector 7 to move along a first direction through the first motion component 32 and drive the flat panel detector 7 to move along a second direction through the second motion component 33. That is, the electric drive unit 31 can electrically drive the flat panel detector 7 to move along the front-back direction and the left-right direction of the detection bed, which expands the detection range of the flat panel detector 7. In particular, it can realize the front-back direction movement. For patients with a wider body, by electrically driving the flat panel detector 7 to move along the front-back direction, the patient does not need to move his body, which can realize multiple exposure imaging, has higher shooting efficiency, and gives the patient a better shooting experience.

[0105] In one embodiment, the second moving component 332 can be an integral structure with the mounting component 4, and the second moving component 332 is a part of the mounting component 4. For example, the mounting component 4 is a box structure, and the lower end of the mounting component 4 has a plate with a large area. The plate at the lower end of the mounting component 4 is provided with a slider that is slidably connected to the second guide rail 3311, and the plate at the lower end of the mounting component 4 is fixedly connected to the second conveyor belt 352, so that the second electric drive component 312 can also electrically drive the mounting component 4 to move along the second guide rail 3311 in the front-back direction of the testing bed.

[0106] Please refer to Figure 4 and Figure 5 In one embodiment, the testing bed further includes a limiting component 5, which can be installed on any of the base 1, the support platform 2, and the electric motion device 3. For example, the limiting component 5 is installed on the mounting plate of the electric motion device 3. The limiting component 5 is used to limit the front limit position and the rear limit position of the mounting member 4 in the front-back direction.

[0107] The limiting component 5 includes a front limiting member 51 and a rear limiting member 52. The front limiting member 51 and the rear limiting member 52 are located at opposite ends of the trajectory of the mounting member 4 moving in the front-back direction. For example, the front limiting member 51 and the rear limiting member 52 can be installed at the front and rear ends of the second mounting plate 3312. The front limiting member 51 is used to block and limit the mounting member 4 at its front-back direction movement to the front limit position, and the rear limiting member 52 is used to block and limit the mounting member 4 at its rear limit position. The front limiting member 51 and the rear limiting member 52 can directly block the two sides of the mounting member 4. The mounting member 4 can also be provided with protruding limiting blocks. Two protruding limiting blocks are provided below the front and rear ends of the mounting member 4. The mounting member 4 achieves blocking and limiting by contacting the front limiting member 51 and the rear limiting member 52 through the two limiting blocks. By providing limiting blocks to the mounting member 4, the front limiting member 51 and the rear limiting member 52 can be positioned below the mounting member 4, reducing the space occupied.

[0108] Please refer to Figure 5 The limiting component 5 includes a front limiting component 51 and a rear limiting component 52. The front limiting component 51 and the rear limiting component 52 are physical limiting components that physically restrict the front and rear extreme positions of the mounting component 4, so that the mounting component 4 does not move beyond the front and rear sides of the support platform 2 in the front and rear direction. This can prevent the mounting component 4 from moving too far back and forth, which could lead to accidents such as collisions between the mounting component 4 and other devices, and also prevent the mounting component 4 from protruding from the front or rear side of the support platform 2, which could affect doctors or other equipment.

[0109] In other embodiments, the limiting component 5 includes one of a front limiting member 51 and a rear limiting member 52, which is used to limit the mounting member 4 to one of its front and rear extreme positions. This configuration allows for unidirectional limiting of the mounting member 4, meeting the needs of special scenarios. For example, when the flat panel detector 7 mainly moves in the area between the middle and front ends in the front-rear direction, setting the front extreme position limit is sufficient; or, when the flat panel detector 7 mainly moves in the area between the middle and rear ends in the front-rear direction, setting the front extreme position limit is sufficient.

[0110] Please refer to Figure 6 and Figure 7 In one embodiment, the limiting component 5 may also include a first limiting switch 53 and a second limiting switch 54, with the first limiting switch 53 and the second limiting switch 54 located at the two ends of the trajectory of the mounting member 4 moving in the front-back direction, for example, the first limiting switch 53 and the second limiting switch 54 are installed at the front and rear ends of the second mounting plate 3312.

[0111] The first limit switch 53 is installed at the front limit position of the mounting part 4 when it moves in the front-back direction. When the mounting part 4 moves to the front limit position, the first limit switch 53 detects the mounting part 4 and triggers the mounting part 4 to stop moving. The second limit switch 54 is installed at the rear limit position of the mounting part 4 when it moves in the front-back direction. When the mounting part 4 moves to the rear limit position, the second limit switch 54 detects the mounting part 4 and triggers the mounting part 4 to stop moving.

[0112] The first limit switch 53 and the second limit switch 54 can be electronic switches such as photoelectric switches and ultrasonic switches. The first limit switch 53 and the second limit switch 54 are electrically connected to the controller 9 of the detection bed. When the first limit switch 53 and the second limit switch 54 detect that the mounting part 4 has moved to the front and rear limit positions, they generate corresponding signals respectively. The controller 9 controls the electric drive 31 (second electric drive 312) to stop electric drive according to the signals generated by the first limit switch 53 and the second limit switch 54, thereby controlling the mounting part 4 and the flat plate detector 7 to stop moving in the front and rear direction.

[0113] The first limit switch 53 and the second limit switch 54 are active limit controls, which can also limit the range of movement of the limit mounting part 4 in the forward and backward directions.

[0114] In other embodiments, the limiting component 5 includes one of a first limiting switch 53 and a second limiting switch 54. The limiting component 5 is used to limit the mounting member 4 to one of its front and rear limit positions. This configuration allows for unidirectional limiting of the mounting member 4, which can meet the needs of special scenarios. For example, when the flat panel detector 7 mainly moves in the area between the middle and front ends in the front-rear direction, setting the limit at the front limit position is sufficient; or, when the flat panel detector 7 mainly moves in the area between the middle and rear ends in the front-rear direction, setting the limit at the front limit position is sufficient.

[0115] In one embodiment, the limiting component 5 may also include a front limiting member 51, a rear limiting member 52, a first limiting switch 53, and a second limiting switch 54, that is, the limiting component 5 includes both physical and electronic limiting, forming dual limiting protection.

[0116] In one embodiment, the limiting component 5 may further include a left limiting member and a right limiting member, which are mounted on the first mounting plate 3212. The left and right limiting members are used to limit the left and right extreme positions of the mounting member 4. This limits the range of movement of the mounting member 4 in the left and right directions, preventing excessive movement of the mounting member 4 in the left and right directions and providing physical limiting protection for the mounting member 4.

[0117] In one embodiment, the limiting component 5 may also include a third limiting switch and a fourth limiting switch, which are mounted on the first mounting plate 3212. The third and fourth limiting switches are used to limit the left and right extreme positions of the mounting member 4. This limits the range of movement of the mounting member 4 in the left and right directions, preventing excessive movement of the mounting member 4 in these directions and providing electronic limit protection for the mounting member 4.

[0118] Please refer to Figure 8 and Figure 10 In one embodiment, the testing bed further includes a first position sensor 61, which can be mounted on the base 1, the support platform 2, or the electric motion device 3. For example, the first position sensor 61 is mounted on the second mounting plate 3312 of the electric motion device 3. The first position sensor 61 is used to detect the position of the mounting member 4 moving in the front-back direction and generates a corresponding first detection signal. The first position sensor 61 is electrically connected to the controller 9, which is used to calculate the first real-time position of the mounting member 4 moving in the front-back direction based on the first detection signal.

[0119] The first position sensor 61 is used to provide real-time feedback on the position of the mounting component 4 moving in the front-back direction, which can improve the accuracy of the movement of the mounting component 4 and the flat panel detector 7 in the front-back direction.

[0120] Please refer to Figure 9 and Figure 10 In one embodiment, the testing bed further includes a second position sensor 62, which can be mounted on the base 1, the support platform 2, or the electric motion device 3. For example, the second position sensor 62 is mounted on the first mounting plate 3212 of the electric motion device 3. The second position sensor 62 is used to detect the position of the mounting member 4 moving in the left-right direction and generates a corresponding second detection signal. The second position sensor 62 is electrically connected to the controller 9, which is used to calculate the second real-time position of the mounting member 4 moving in the left-right direction based on the second detection signal.

[0121] The second position sensor 62 is used to provide real-time feedback on the position of the mounting component 4 moving in the left and right directions, which can improve the accuracy of the movement of the mounting component 4 and the flat panel detector 7 in the left and right directions.

[0122] The first position sensor 61 and the second position sensor 62 may include at least one or more of the following: a laser, a pull-wire sensor, an encoder, a potentiometer, and a grating. The laser and the pull-wire sensor are mounted on components such as the first mounting plate 3212 or the second mounting plate 3312, while the encoder, potentiometer, and grating may be mounted on the synchronous pulley or motor of the electric motion device 3.

[0123] Please refer to Figure 11In one embodiment, there is a receiving space between the support platform 2 and the base 1. The electric motion device 3 and the mounting component 4 are located in the receiving space between the support platform 2 and the base 1. One of the front and rear sides of the receiving space has an exposed opening 11. Part or all of the mounting component 4 can be moved along the front-rear direction of the detection bed to expose the exposed opening 11, so as to facilitate the doctor to install or remove the flat panel detector 7 inside the mounting component 4.

[0124] Please refer to Figure 11 In one embodiment, the testing bed further includes a protective door 8, which is movably installed at the exposed opening 11. The protective door 8 has an open state and a closed state. When closed, the protective door 8 can cover the exposed opening 11; when open, it can open the exposed opening 11. This arrangement allows the receiving space to be covered and sealed by the protective door 8, providing isolation and protection for the electric motion device 3 and the mounting component 4 within the receiving space.

[0125] There are several possible locations for the exposed opening 11. For example, in one embodiment, the exposed opening 11 is located on both the front and rear sides of the testing bed. In another embodiment, the exposed opening 11 is located on one of the front or rear sides of the testing bed. In yet another embodiment, the exposed opening 11 is located on at least one of the left or right sides of the testing bed.

[0126] Regarding the size of the exposed opening 11, in one embodiment, at least one exposed opening 11 is sized to allow the mounting component 4 to enter and exit, enabling the assembly and disassembly of the flat panel detector 7. That is, at least one exposed opening 11 serves as an inlet / outlet for the mounting component 4. For example, in one embodiment, since doctors typically stand at the front of the examination bed, the front of the examination bed has a larger space for movement. Therefore, the exposed opening 11 at the front of the examination bed serves as the inlet / outlet for the mounting component 4, making it easier to handle the mounting component 4 through the exposed opening 11. In another embodiment, both the exposed opening 11 at the front and rear of the examination bed are sized to allow the mounting component 4 to enter and exit, and both the exposed opening 11 at the front and rear of the examination bed are equipped with protective doors 8.

[0127] In other embodiments, the size of the exposed opening 11 may also be smaller than the size of the mounting member 4. In this case, the exposed opening 11 is only used for the position or movement of the mounting member 4.

[0128] In one embodiment, to facilitate the placement and removal of the flat panel detector 7, the mounting component 4 is installed in the receiving space, and the mounting component 4 has a drawer-type tray structure. When placing the flat panel detector 7, the tray structure is pulled out from the exposed opening 11, allowing the mounting component 4 to be inserted or removed from the exposed opening 11. After the flat panel detector 7 is placed on the tray structure, it is pushed into the mounting component 4. The flat panel detector 7 can be placed in or removed from the mounting component 4 via the tray structure, making operation more convenient. Of course, in other embodiments, the mounting component 4 can also be removed entirely from the exposed opening 11, the flat panel detector 7 can be placed in the mounting component 4, and then placed entirely into the receiving space.

[0129] In one embodiment, since a protective door 8 is installed at the exposed opening 11, the protective door 8 needs to be opened before the mounting component 4 is installed or removed from the exposed opening 11. After the protective door 8 is opened, in order to enable the protective door 8 to automatically reset, the testing bed includes an elastic reset component (not shown in the figure). The elastic reset component can apply a spring force to the protective door 8 to move it to the closed state when the protective door 8 is open. For example, the elastic reset component is a torsion spring, and the protective door 8 is oscillatingly mounted on the testing bed, with the torsion spring installed at the oscillation axis of the protective door 8. In other embodiments, the elastic reset component can also be a spring sheet or a coil spring, which can also achieve the automatic reset and closure of the protective door 8.

[0130] In one embodiment, the testing bed further includes a linkage mechanism (not shown in the figure), which is used to associate the protective door 8 with the electric motion device 3, which can electrically drive the protective door 8 to open.

[0131] The linkage mechanism may include one or more of a linkage assembly and a gear assembly. One end of the linkage mechanism is connected to a moving component such as a transmission belt in the electric motion device 3, and the other end is connected to the protective door 8. When the mounting piece 4, on which the flat panel detector 7 is mounted, moves to a preset position before the exposed opening 11, the electric motion device 3 opens the protective door 8 via the linkage mechanism. The protective door 8 can be closed via the linkage mechanism, or it can be manually or by a resilient reset component.

[0132] In other embodiments, the protective door 8 has a pressing engagement portion, which is pressed against by the mounting member 4 as it moves to the exposed opening 11, thereby opening the protective door 8. When the mounting member 4 moves to be concealed within the receiving space, it releases the pressing engagement of the protective door 8, which can be manually or by a resilient reset member to close.

[0133] In one embodiment, the protective door 8 is transparent or semi-transparent in order to allow observation of the position of the mounting component 4. In another embodiment, the protective door 8 is a plastic door or a glass door.

[0134] In one embodiment, an X-ray imaging system examination bed is provided. The difference between the examination bed in this embodiment and the examination bed in any of the above embodiments is that the electric motion device 3 of this examination bed only includes an electric drive component 31 and a second motion component 33, that is, the mounting component 4 and the flat panel detector 7 of this examination bed can move along the front and back direction of the examination bed.

[0135] The electric drive component 31 in this embodiment includes a first electric drive component 311. The first electric drive component 311 and the second motion component 33 and other components in this embodiment are the same as those in the above embodiment, and will not be described again.

[0136] In this embodiment, the detection bed has an electric motion device 3 including an electric drive unit 31 and a second motion component 33. The electric drive unit 31 can drive the flat panel detector 7 to move along the second direction through the second motion component 33. That is, the electric drive unit 31 can electrically drive the flat panel detector 7 to move along the front-back direction of the detection bed, which expands the detection range of the flat panel detector 7. In particular, it can achieve front-back movement. For patients with a wider body, by electrically driving the flat panel detector 7 to move along the front-back direction, the patient does not need to move their body, which can achieve multiple exposure imaging, has higher shooting efficiency, and provides patients with a better shooting experience.

[0137] In one embodiment, the detection bed further includes a controller 9, which can realize pure electric control of the electric motion device 3. The controller 9 automatically controls the electric motion device 3 according to the instructions to drive the mounting part 4 and the flat plate detector 7 mounted on the mounting part 4 to move in the front-back direction and / or left-right direction.

[0138] The controller 9 can be installed in any location, such as inside or on the side of the testing bed, or it can be installed outside the testing bed.

[0139] The controller 9 is signal-connected to the electric drive unit 31, such as the controller 9 being signal-connected to the first electric drive unit 311 and the second electric drive unit 312. The controller 9 is used to control the first electric drive unit 311 and the second electric drive unit 312 to drive individually or in conjunction, thereby driving the first motion component 32 and / or the second motion component 33 to move individually or in conjunction, so as to drive the mounting part 4 and the flat plate detector 7 mounted on the mounting part 4 to move in one of the front-back direction and the left-right direction, or to drive the mounting part 4 and the flat plate detector 7 mounted on the mounting part 4 to move simultaneously in the front-back direction and the left-right direction.

[0140] Please refer to Figure 12In one embodiment, the examination bed or its exterior is equipped with input components 20, such as buttons and a display screen. These input components 20 are connected to the controller 9. The doctor can input commands through the input components 20 to control the installation component 4 and the flat panel detector 7 mounted on it to move to a designated position in the forward / backward and / or left / right directions. For example, the input component 20 includes left, right, forward, and backward movement keys; pressing the corresponding key controls the flat panel detector 7 to move in the corresponding direction.

[0141] In another embodiment, the flat panel detector 7 is linked to the emitting component of the X-ray imaging system and is set to follow. The emitting component is equipped with a position sensor. The controller 9 senses the position of the emitting component in real time through the position sensor and controls the flat panel detector 7 in the examination bed to move directly below the emitting component, so as to achieve automatic following control. This process does not require the doctor to manually control the movement of the flat panel detector 7 in the examination bed.

[0142] Please refer to Figure 13 In one embodiment, the testing bed further includes a controller 9 and an operating element 30. The operating element 30 is equipped with a force sensor 301. The combination of the controller 9 and the operating element 30 can realize electric power-assisted drive, and control the installation element 4 and the flat plate detector 7 installed on the installation element 4 to move in the front-back direction and / or left-right direction, and control the speed of its movement, according to the direction and magnitude of the force applied by the doctor.

[0143] The controller 9 can be installed anywhere inside or on the side of the testing bed, or it can be installed outside the testing bed. The operating component 30 can be installed anywhere outside the testing bed, or it can be installed at an external location at a certain distance from the testing bed.

[0144] The operating component 30 can be a swingable or movable structure such as an operating handle. For example, the operating component 30 can swing in the front-back direction and the left-right direction. The front-back direction corresponds to the front-back direction of the testing bed, and the left-right direction corresponds to the left-right direction of the testing bed.

[0145] The operating component 30 is equipped with a force sensor 301. The force sensor 301 can be a combination of multiple single-dimensional sensors, or a two-dimensional force sensor or a multi-dimensional force sensor. The force sensor 301 is used to detect the direction and magnitude of the force applied by the doctor to the operating component 30 and generate a corresponding detection signal.

[0146] The controller 9 is signal-connected to the electric drive unit 31 and the force sensor 301, such as the controller 9 being signal-connected to the first electric drive unit 311, the second electric drive unit 312, and the force sensor 301. The controller 9 can control the electric drive unit 31 to drive the mounting part 4 and the flat plate detector 7 mounted on the mounting part 4 to move in the direction and speed of movement based on the detection signal generated by the force sensor 301.

[0147] The movement of the flat panel detector 7 is driven by electric assistance, making it more convenient for doctors to use. Doctors can directly control the direction and speed of movement of the flat panel detector 7 to move it to the accurate position.

[0148] Please refer to Figure 14 In one embodiment, an X-ray imaging system is provided, which includes an emitting device 10 and a detection bed as described in any of the above embodiments.

[0149] The emitting device 10 can be a suspended structure, including an emitting component 101 and a suspension assembly 102. The emitting component 101 is the head unit and is used to emit X-rays. The suspension assembly 102 can be installed below the ceiling, and the emitting component 101 is installed on the suspension assembly 102. The suspension assembly 102 can drive the emitting component 101 to float in three dimensions.

[0150] The suspension assembly 102 mainly includes a third guide, a fourth guide, a second moving part, a lifting arm, and a rotating arm. The third guide is laid on the ceiling along the left-right direction of the testing bed and is fixedly installed relative to the ceiling. The fourth guide is laid on the third guide along the front-back direction of the testing bed and can move relative to the third guide in the left-right direction. The third guide can have two parallel lines forming a frame structure, and the fourth guide can also have two parallel lines forming a frame structure. Both the third and fourth guides adopt a frame-type double-rail structure, which can improve the uniformity of force distribution and the smoothness of sliding. The third and fourth guides can be slide rails, and the second moving part can be a sliding trolley or a sliding block.

[0151] The second moving member is movably mounted on the fourth guide member. The second moving member can move with the fourth guide member relative to the third guide member in the left-right direction, and the second moving member can also move relative to the fourth guide member in the front-back direction.

[0152] The lifting arm includes a first end and a second end, which can be the upper end and the second end can be the lower end. The first end of the lifting arm is connected to a second moving part, and the lifting arm is suspended from the lower end of the second moving part. The second end of the lifting arm can move up and down relative to the first end.

[0153] The rotating arm is connected to the second end of the lifting arm, allowing it to rotate vertically relative to the first end of the lifting arm. The rotating arm and the second end of the lifting arm can be rotatably connected via components such as a shaft and bearings; that is, a rotating joint is located at the lowest end of the lifting arm. The rotating arm can also be vertically connected to the lifting arm, meaning it can be horizontally positioned and rotate vertically within a horizontal plane.

[0154] The launching component 101 is mounted on a rotating arm, and the suspension assembly 102 can drive the launching component 101 to move in three-dimensional space.

[0155] The emitting component 101 can be moved directly above the support platform 2. At this time, the emitting component 101 can vertically emit X-rays from top to bottom to irradiate the patient lying flat on the support platform 2, and the flat panel detector 7 can receive the X-rays passing through the patient lying flat. The emitting component 101 can also be moved to the front side of the support platform 2. At this time, the emitting component 101 horizontally emits X-rays from front to back to irradiate the patient lying on their side on the support platform 2, and other flat panel detectors can receive the X-rays passing through the patient lying flat.

[0156] In other embodiments, the transmitting device 10 may also be a vertical structure. The transmitting device 10 includes a vertical mounting component, and the transmitting component 101 is movably mounted on the vertical mounting component. For example, the vertical mounting component is a ring structure, and the supporting platform 2 passes through the middle of the vertical mounting component of the ring structure. By rotating on the vertical mounting component of the ring structure, the transmitting component 101 can also move to the upper end of the supporting platform 2 to realize the imaging of the supine patient, and can also move to one side of the supporting platform 2 in the front-back direction to realize the imaging of the lateral decubitus patient.

[0157] In this embodiment of the X-ray imaging system, the electric motion device 3 of the examination bed includes an electric drive 31, a first motion component 32, and a second motion component 33. The electric drive 31 can drive the flat panel detector 7 to move along a first direction through the first motion component 32 and along a second direction through the second motion component 33. That is, the electric drive 31 can electrically drive the flat panel detector 7 to move along the front-back and left-right directions of the examination bed, expanding the detection range of the flat panel detector 7. In particular, it can achieve front-back movement. For patients with a wider body, by electrically driving the flat panel detector 7 to move along the front-back direction, the patient does not need to move their body, which can achieve multiple exposure imaging, resulting in higher shooting efficiency and a better shooting experience for the patient.
