Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a shared bed and a diagnosis and treatment system. Background Art

[0002] Radiation therapy is an important means of tumor treatment, using high-energy rays to kill cancer cells.

[0003] In terms of equipment setup, some technologies integrate imaging and radiotherapy equipment into a single unit to save space. However, this approach presents a serious problem: significant interference between the two devices leads to poor imaging quality and significantly compromises radiotherapy effectiveness. While separating the two devices reduces interference and improves both imaging and radiotherapy effectiveness, it also introduces new challenges. For example, when transferring the patient between the imaging and radiotherapy equipment, their position can change, compromising treatment effectiveness.

[0004] This requires finding a balance in equipment layout and patient position fixation, eliminating interference between devices while ensuring the stability of the patient's position, so as to achieve accurate and effective radiotherapy, improve the success rate of tumor treatment, reduce treatment errors caused by changes in equipment layout and position, and provide patients with better medical services. Summary of the Invention

[0005] The purpose of this application is to provide a shared bed and a diagnosis and treatment system, aiming to solve the problem that changes in the patient's body position during the diagnosis and treatment process may affect the treatment effect.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, the present application provides a shared bed, which includes a common bed board and a driving platform, wherein the driving platform is connected to the common bed board, and the driving platform is used to drive the common bed board to move along a preset path and disengage from the common bed board so that the common bed board is transferred from the driving platform to a preset position; and / or, the driving platform is used to dock with the common bed board and drive the common bed board to move along a preset path toward the driving platform so that the common bed board is transferred from the preset position to the driving platform.

[0008] On this basis, the shared bed in this application can be transferred between different positions via a drive platform, providing a continuous load-bearing platform for the patient. During the diagnosis and treatment process, the patient always stays on the shared bed, without having to change the bed from imaging to radiotherapy, greatly reducing the risk of position changes, thereby further improving the accuracy of treatment.

[0009] In addition, the drive platform can accurately transfer the shared bed board along the preset path, thereby ensuring the stability of the patient's position from the imaging position to the treatment position and preventing deviation in high-energy radiation exposure due to changes in body position.

[0010] Furthermore, the drive table enables automated transfer of the shared bed. While the patient is waiting (for example, after imaging and awaiting treatment planning), the drive table automatically moves the bed from the imaging device (the first position) to the pre-set position of the radiotherapy device, effectively utilizing waiting time and avoiding the errors of manual transfer. Its precise positioning function ensures that the shared bed is accurately positioned during both imaging and radiotherapy, improving imaging accuracy and radiotherapy precision, and optimizing the entire diagnosis and treatment process.

[0011] Finally, from a patient perspective, the entire process reduces discomfort. Patients no longer need to frequently change beds or adjust their body positions. Instead, they simply lie quietly on a shared bed, completing different stages of treatment in a comfortable and stable state. This relieves tension, improves treatment tolerance, and provides a better patient experience, facilitating smoother treatment progress.

[0012] In some embodiments, the driving platform includes a platform body, a screw and a driving assembly. The screw is connected to the platform body in a transmission manner. The driving assembly is arranged on the platform body. The driving assembly is connected to the screw in a transmission manner. The driving assembly is used to drive the screw to rotate so that the common bed board moves in a preset direction relative to the driving platform.

[0013] In some embodiments, the drive assembly includes a servo motor, a driving pulley, a synchronous belt and a passive pulley. The driving pulley is connected to the output end of the servo motor. The servo motor is used to drive the driving pulley to rotate. The synchronous belt is partially wound around the driving pulley, and the synchronous belt is partially wound around the passive pulley. The output end of the passive pulley is connected to the screw. The driving pulley drives the passive pulley to rotate through the synchronous belt to drive the screw to rotate.

[0014] In some embodiments, the shared bed in the present application further includes a first roller group and a first guide rail, the first roller group is rotatably connected to the shared bed board, the first guide rail is provided on the driving platform, and the first roller group is rollingly connected to the first guide rail.

[0015] In some embodiments, the shared bed in the present application also includes a second roller group and a second guide rail. The second roller group is rotatably connected to the common bed board, and the second roller group and the first roller group are spaced apart in a direction perpendicular to the movement direction of the common bed board. The second guide rail is provided on the driving platform, and the second guide rail and the first guide rail are spaced apart in a direction perpendicular to the movement direction of the common bed board. The second roller group is rollingly connected to the second guide rail.

[0016] In some embodiments, the common bed board is provided with a matching piece, and a locking piece is provided at a preset position, and the locking piece is used to lock the matching piece so that the common bed board is fixed at the preset position.

[0017] In some embodiments, the mating piece is one of the positioning pin and the positioning hole, and the locking piece is the other of the positioning pin and the positioning hole; or, the locking piece is an electromagnetic locking device, and the locking piece is used to lock the mating piece to fix the common bed board.

[0018] In some embodiments, the platform is provided with a third guide rail, and the shared bed in the present application also includes a nut, a slider and a positioning block. The nut is connected to the lead screw, and the nut is connected to the common bed board. The lead screw drives the nut to move to drive the common bed board to move along the axial direction of the lead screw. The slider is slidably arranged between the third guide rail and the common bed board, and the slider is connected to the lead screw. The positioning block is connected to the slider. The lead screw is used to drive the slider to move to drive the positioning block to move, and the positioning block is arranged between the drive assembly and the nut. When the nut is disengaged from the lead screw, the positioning block is used to push the common bed board to continue moving.

[0019] In some embodiments, after the screw rotates forward to drive the common bed board to a preset position, the nut disengages from the screw. An elastic pushing member is provided at the preset position. When the common bed board is at the preset position, the elastic pushing member applies a pushing force toward the screw to push the common bed board toward the screw so as to dock the nut with the screw. The screw reverses to move the nut to the circumferential side of the screw.

[0020] In the second aspect, the present application provides a diagnosis and treatment system, which includes radiotherapy equipment, imaging equipment and the above-mentioned shared bed. The radiotherapy equipment has a radiotherapy position, the imaging equipment is arranged opposite to the radiotherapy equipment, the imaging equipment has an imaging position, and the driving platform is used to drive the common bed board to move between the radiotherapy position and the imaging position.

[0021] In some embodiments, the imaging device includes at least one of an MRI device, a CT device, and a PET device.

[0047] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] The term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0049] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0050] Furthermore, the terms "including," "having," and any variations thereof, as used in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0051] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0052] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0053] First, for ease of understanding, the terms used in this application are explained.

[0054] (1) Imaging equipment

[0055] The imaging device mentioned in this application refers to a device that uses various physical principles and technologies to image the internal structure and physiological functions of the human body, providing an important basis for medical diagnosis, treatment and research.

[0056] Among them, the imaging means of imaging equipment mainly include: X-ray imaging, magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET) imaging, radionuclide imaging (nuclear medicine imaging technology) and ultrasound imaging and other technical means. This application uses magnetic resonance imaging as an example.

[0057] MRI uses strong magnetic fields and radiofrequency waves to induce resonance signals in hydrogen nuclei within the human body. The differences in hydrogen atom signals in different tissues are captured by a receiving coil and converted into an image. MRI is generally used for detailed imaging of the brain, spine, and musculoskeletal system, diagnosis of soft tissue lesions (such as tumors and inflammation), and imaging of the heart and blood vessels.

[0058] (2) Radiotherapy equipment

[0059] Radiotherapy equipment uses high-energy radiation to irradiate tumors and other diseased tissues to treat diseases. Common radiotherapy equipment includes the medical linear accelerator, the gamma knife, integrated radiotherapy equipment that combines a medical linear accelerator and a gamma knife, and the CyberKnife.

[0060] It can be seen that imaging equipment provides information for the "diagnosis" in the diagnosis and treatment process, and radiotherapy equipment provides means for the "treatment" in the diagnosis and treatment process. The two cooperate and complement each other.

[0061] Based on the above, in some embodiments, the present application provides a diagnosis and treatment system, wherein the diagnosis and treatment system includes an imaging device, a radiotherapy device, and a shared bed. The present application integrates the imaging device and the radiotherapy device into the same treatment room, and the shared bed can be transferred between the imaging device and the radiotherapy device, thereby integrating the entire system into one through the shared bed between the imaging device and the radiotherapy device.

[0062] In some embodiments, see Figure 1 The imaging device 100 has an imaging position 101 for imaging, and the radiotherapy device 200 has a radiotherapy position 201 for radiotherapy. The shared bed includes a shared bed plate 300 and a driving platform 400 for driving the shared bed plate 300 to move. The driving platform 400 is used to drive the shared bed plate 300 to move between the radiotherapy position 201 and the imaging position 101.

[0063] It should be noted that the imaging position 101 mentioned in this application is the position in the imaging device 100 used to image the target object, such as a patient, located on the shared bed, and the radiotherapy position 201 is the position in the radiotherapy device 200 used to perform radiotherapy on the target object, such as a patient, located on the shared bed.

[0064] Based on the above technical means, on the one hand, the radiotherapy system involved in this application does not need to integrate the imaging device and the radiotherapy device into one system, avoiding huge costs. Instead, the common bed board 300 is controlled by the driving platform 400 to transfer the patient smoothly, accurately and quickly between the imaging device 100 and the radiotherapy device, ensuring that the patient's position on the imaging device and the radiotherapy device is completely consistent, thereby improving the accuracy of radiotherapy and enabling the radiation to more accurately irradiate the tumor target area.

[0065] On the other hand, the system in this application not only improves the adaptive radiotherapy function based on imaging equipment such as MRI equipment, but also optimizes the diagnosis and treatment process, making it smoother and more efficient. For example, after the patient is imaged and waiting for radiotherapy (i.e., the time for adaptively adjusting the treatment plan based on the images obtained by the imaging equipment), the shared bed is automatically and stably transferred from the imaging position to the radiotherapy position at a low speed. In this way, the patient can receive radiotherapy as soon as he arrives at the radiotherapy position, greatly shortening the patient's radiotherapy waiting time, improving the efficiency of diagnosis and treatment, making the entire adaptive process more compact, reducing the patient's stay time in the treatment room, and improving the turnover rate of the treatment room.

[0066] It should be noted that the imaging device 100 in the present application includes at least one of an MRI device, a CT device, and a PET device, and the present application does not limit this.

[0067] It is understandable that, depending on the different arrangements of the diagnosis and treatment system, the shared bed in this application can also realize the conversion between multiple imaging devices 100 and multiple radiotherapy devices 200.

[0068] It should be noted that the application scenario mentioned in this application is only one scenario in the actual application of shared beds. It can also be used in other required scenarios, and this application does not limit this.

[0069] In some embodiments, the materials used in the diagnosis and treatment system of the present application have properties such as radiation resistance, non-magneticity, and non-conductivity, and can meet requirements such as ultraviolet and chemical disinfection.

[0070] In some embodiments, see Figure 1 The driving platform 400 in this application is connected to the common bed board 300. The driving platform 400 can be used to drive the common bed board 300 to move along a preset path and disengage from the common bed board 300 so that the common bed board 300 is transferred from the driving platform 400 to a preset position; and / or, the driving platform 400 is used to dock with the common bed board 300 and drive the common bed board 300 to move along a preset path toward the driving platform 400 so that the common bed board 300 is transferred from the preset position to the driving platform.

[0071] It should be noted that, taking the example of the driving platform 400 driving the shared bed plate 300 to transfer a target object (e.g., a patient) between the imaging position 101 of the imaging device 100 and the radiotherapy position 201 of the radiotherapy device, the patient can be transferred from the imaging position to the radiotherapy position or from the radiotherapy position to the imaging position. The "preset position" can be the radiotherapy position 201 of the radiotherapy device 200 or the imaging position 101 of the imaging device 100, and the "preset path" refers to the path between the imaging position 101 and the radiotherapy position 201. In other words, the "preset position" can be the target position to which the shared bed plate 300 needs to be transferred, and the "preset path" can be the path that the shared bed plate 300 needs to move to when transferred to the corresponding target position.

[0072] The preset path can be a curve or a straight line. This application uses the preset path as a straight line for exemplary description.

[0073] When the preset path is a straight line, see Figure 1 and combined Figure 2 The imaging device 100 and the radiotherapy device 200 are arranged at intervals along the horizontal direction of the Y axis (i.e., the length direction of the shared bed). For example, the imaging device 100 and the radiotherapy device 200 are arranged at intervals in the same direction or in different directions along the positive direction of the Y axis.

[0074] In other embodiments, please refer to Figure 1 A first movable platform 102, such as a diagnostic bed, is provided on the side of the imaging device 100 facing away from the radiotherapy device 200. The radiotherapy device 200 is provided with a second movable platform 202, such as a radiotherapy bed. The second movable platform 202 is provided between the imaging device 100 and the radiotherapy device 200.

[0075] In some embodiments, see Figure 3 Combined with Figure 4 , the shared bed in the present application can be arranged on the first mobile platform 102, and the first mobile platform 102 can drive the shared bed to move in any direction of the X-axis direction, the Y-axis direction and the Z-axis direction. Among them, the X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other, and the Z-axis direction is parallel to the vertical direction (direction of gravity). Exemplarily, the coordinate system in which the X-axis, the Y-axis and the Z-axis are located is the IEC 61217 coordinate system, wherein the X-axis is the left-right direction, and the right direction is positive; the Y-axis is the front-back direction, and the forward direction is positive; the Z-axis is the up-down direction (direction of gravity), and the upward direction is positive.

[0076] The first movable platform 102 is slidably connected to the driving platform 400, and the first movable platform 102 is capable of driving the driving platform 400 and the shared bed plate 300 thereon to move at least along the positive direction of the Y-axis. Simultaneously, the driving platform 400 can also drive the shared bed plate 300 to move along the path (i.e., the preset path) between the imaging position 101 and the radiotherapy position 201 and disengage from the shared bed plate 300, thereby transferring the shared bed plate 300 from the driving platform 400 to the second movable platform 202 (i.e., the preset position) of the radiotherapy device. Furthermore, the driving platform 400 can also be configured to dock with the shared bed plate 300 and drive the shared bed plate 300 to move along the path (i.e., the preset path) between the imaging position 101 and the radiotherapy position 201 toward the driving platform 400, thereby transferring the shared bed plate 300 from the second movable platform 202 (i.e., the preset position) of the radiotherapy device to the driving platform.

[0077] In some embodiments, the first movable platform 102 is provided with a slide rail extending in the horizontal direction along the Y-axis, and the drive platform 400 is provided with a sliding block that is slidably connected to the slide rail. In other embodiments, the first movable platform 102 is provided with a ridge extending in the horizontal direction along the Y-axis, and the drive platform 400 is provided with a groove that is slidably connected to the ridge.

[0078] In some embodiments, a power element is provided on the first mobile platform 102 and is in transmission connection with the drive platform 400 to propel the drive platform 400 along the positive or negative direction of the Y-axis. For example, the power element may be an electric telescopic rod. In another example, the power element may be a hydraulic push rod.

[0079] It should be noted that the way in which the first mobile platform 102 drives the shared bed to move in the X-axis direction can refer to the way in which the first mobile platform 102 drives the shared bed to move in the horizontal direction along the Y-axis, which will not be elaborated in this application.

[0080] In some embodiments, the first mobile platform 102 is connected to a lifting assembly that can control the position of the first mobile platform 102 on the Z axis, thereby driving the shared bed to move on the Z axis. For example, the lifting assembly can be a hydraulic lift. In another example, the lifting assembly can be a rail-type lift.

[0081] In some embodiments, see Figure 7 and combined Figure 8 After the second mobile platform 202 is connected to the shared bed plate 300, it can also drive the shared bed to move in any of the X-axis, Y-axis, and Z-axis directions. The specific connection method is the same as the connection between the first mobile platform 102 and the drive platform 400, and this application will not elaborate on this.

[0082] In other embodiments, the shared bed in the present application may also be placed on a second mobile platform 202, which can drive the shared bed to move in any of the X-axis, Y-axis, and Z-axis directions. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other, and the Z-axis direction is parallel to the vertical direction (the direction of gravity).

[0083] The second movable platform 202 is slidably connected to the driving platform 400, and the second movable platform 202 is capable of driving the driving platform 400 and the common bed board 300 thereon to move at least along the positive or negative direction of the Y-axis. Simultaneously, the driving platform 400 can also drive the common bed board 300 to move along the path (i.e., the preset path) between the imaging position 101 and the radiotherapy position 201 and disengage from the common bed board 300, thereby transferring the common bed board 300 from the driving platform 400 to the first movable platform 102 (i.e., the preset position) of the imaging device. Furthermore, the driving platform 400 can also be configured to dock with the common bed board 300 and drive the common bed board 300 to move along the path (i.e., the preset path) between the imaging position 101 and the radiotherapy position 201 toward the driving platform 400, thereby transferring the common bed board 300 from the first movable platform 202 (i.e., the preset position) of the imaging device 100 to the driving platform.

[0084] In some embodiments, the second movable platform 202 is provided with a slide rail extending in the horizontal direction of the Y-axis, and the drive platform 400 is provided with a sliding block that is slidably connected to the slide rail. In other embodiments, the second movable platform 202 is provided with a ridge extending in the horizontal direction of the Y-axis, and the drive platform 400 is provided with a groove that is slidably connected to the ridge.

[0085] In some embodiments, a power element is provided on the second mobile platform 202, which is in transmission connection with the drive platform 400 and drives the drive platform 400 to move along the positive or negative direction of the Y-axis. For example, the power element may be an electric telescopic rod. In another example, the power element may be a hydraulic push rod.

[0086] It should be noted that the way in which the second mobile platform 202 drives the shared bed to move in the X-axis direction can refer to the way in which the first mobile platform 102 drives the shared bed to move in the positive or negative direction of the Y-axis, which will not be elaborated in this application.

[0087] In some embodiments, the second mobile platform 202 is connected to a lifting assembly that can control the position of the second mobile platform 202 on the Z axis, thereby driving the shared bed to move on the Z axis. For example, the lifting assembly can be a hydraulic lift. In another example, the lifting assembly can be a rail-type lift.

[0088] In some embodiments, after being connected to the shared bed board 300, the first mobile platform 102 can also drive the shared bed to move in any positive or negative direction corresponding to the X-axis, Y-axis, and Z-axis. The specific connection method is consistent with the connection relationship between the second mobile platform 202 and the drive platform 400, and this application does not elaborate on this.

[0089] In some embodiments, the metal portion of the first moving platform 202 is made of non-magnetic material.

[0090] The structure of the drive platform will be explained in detail below.

[0091] In some embodiments, the driving platform 400 can be an electric telescopic rod, which can control the movement of the shared bed board 300. On this basis, the electric telescopic rod is connected to the shared bed to achieve separation and connection with the shared bed board 300.

[0092] In some embodiments, see Figure 5 、 Figure 9 and combined Figure 10 The driving platform 400 in the present application may include a platform body 401, a lead screw 402 and a driving assembly 403. The lead screw 402 is transmission-connected to the platform body 401. The driving assembly 403 is arranged on the platform body 401. The driving assembly 403 is transmission-connected to the lead screw 402. The driving assembly 403 is used to drive the lead screw 402 to rotate so that the common bed board 300 moves relative to the driving platform 400.

[0093] The lead screw 402 can rotate relative to the platform 401 to drive the common bed board 300 to move.

[0094] In some embodiments, the platform 401 can be set on the first movable platform 102. The platform 401 serves as a relatively stable basic support part of the entire structure, providing a support for the installation and fixation of the screw 402, and the screw 402 cooperates with the common bed board 300 to drive it to perform corresponding displacement.

[0095] The driving assembly 403 drives the lead screw 402 to rotate. When the lead screw 402 rotates, it generates a force on the common bed board 300 to drive the common bed board 300 to move along a preset path (ie, the axial direction of the lead screw 402).

[0096] In addition, the direction of the circumferential movement of the common bed plate 300 along the lead screw 402 will also vary depending on the direction of rotation of the lead screw 402. This application uses the example of the lead screw 402 rotating clockwise to drive the common bed plate 300 to move along the axial direction of the lead screw 402 and toward the radiotherapy device 200. Correspondingly, when the lead screw 402 rotates counterclockwise, the lead screw 402 can drive the common bed plate 300 to move along the axial direction of the lead screw 402 and away from the radiotherapy device 200.

[0097] Of course, during the above process, the lead screw 402 can also drive the common bed plate 300 to move along the axial direction of the lead screw 402 and toward the radiotherapy device 200 when rotating counterclockwise. Correspondingly, the lead screw 402 can drive the common bed plate 300 to move along the axial direction of the lead screw 402 and away from the radiotherapy device 200 when rotating clockwise. This application does not limit this. For ease of description, this application assumes that the clockwise rotation of the lead screw 402 is forward rotation, and the counterclockwise rotation of the lead screw 402 is reverse rotation.

[0098] For example, please refer back to Figure 1 When the lead screw 402 rotates forward, the lead screw 402 drives the common bed to move in the direction toward the radiotherapy device 200 ; when the lead screw 402 rotates reversely, the lead screw 402 drives the common bed to move in the direction toward the imaging device 100 .

[0099] On the one hand, the screw 402 transmission has high precision and can achieve precise control of small displacements. In some cases where fine adjustments to the patient's position are required, such as adjusting the position of the patient's head or limbs during the scanning process, the screw 402 transmission can accurately achieve these fine adjustments to meet different scanning requirements.

[0100] On the other hand, the present application utilizes the drive platform 400 to further adjust the patient's position at the imaging position 101. By adjusting the length, pitch, and other parameters of the lead screw 402, the movement range and speed of the shared bed plate 300 can be easily changed, allowing it to adapt to the imaging requirements of different models of imaging devices 100. For example, the movement range of the shared bed plate 300 can be flexibly adjusted to meet the requirements of patients of different body shapes or different scanning areas, thereby improving the versatility and adaptability of the device.

[0101] The operator can control the motion of the common bed board 300 simply by controlling the operation of the drive assembly 403. At the same time, the motion driven by the lead screw 402 is highly intuitive, and the operator can accurately adjust the position of the common bed board 300 according to actual needs, thereby improving the operating convenience and work efficiency of the equipment.

[0102] In some embodiments, the driving component 403 may be a motor, and the output end of the motor may drive the lead screw 402 to rotate.

[0103] In some embodiments, see Figure 9 and combined Figure 10 The driving assembly 403 includes a servo motor 4031 , which provides power for the movement of the lead screw 402 .

[0104] The drive assembly 403 includes a driving pulley 4032, a synchronous belt 4033, and a driven pulley 4034. The driving pulley 4032 is connected to the output end of the servo motor 4031, and the servo motor 4031 is used to drive the driving pulley 4032 to rotate. The synchronous belt 4033 is partially wound around the driving pulley 4032, and the synchronous belt 4033 is partially wound around the driven pulley 4034. The output end of the driven pulley 4034 is connected to the lead screw 402. The driving pulley 4032 drives the driven pulley 4034 to rotate through the synchronous belt 4033, thereby driving the lead screw 402 to rotate.

[0105] When servo motor 4031 begins to rotate, its output shaft drives active pulley 4032 to rotate synchronously. Active pulley 4032 acts as the initial "drive wheel" of the transmission system, transmitting the power generated by servo motor 4031. Active pulley 4032, in turn, transmits the power to passive pulley 4034 via a synchronous belt 4033. Passive pulley 4034, receiving the power from synchronous belt 4033, in turn drives lead screw 402 to rotate.

[0106] The servo motor 4031 has high-precision position and speed control capabilities, can accurately drive the active pulley 4032 to rotate, and transmit it to the passive pulley 4034 through the synchronous belt 4033, and finally accurately control the rotation of the screw 402, thereby achieving precise positioning and smooth speed change of the shared bed board 300 on the preset path. In addition, the synchronous belt 4033 has smooth transmission, which can effectively reduce the vibration and noise generated by the shared bed board 300 during movement, creating a comfortable environment for patients while ensuring stable operation of the equipment.

[0107] In some embodiments, the driving component 403 in the present application is provided with a shielding layer.

[0108] For example, the housings of the servo motor 4031 and the driving pulley 4032 are made of materials with good electromagnetic shielding properties. On the control circuit board of the drive motor, metal shielding covers are used to isolate sensitive electronic components and circuit parts.

[0109] As another example, all wires of drive assembly 403 may be double-layer electromagnetically shielded wires. Double-layer shielded wires consist of two shielding layers and an insulating layer in between. The outer shielding layer is typically made of a metal braid or metal foil, which has high mechanical strength and good electromagnetic shielding performance; the inner shielding layer is typically made of a tinned copper braid or aluminum foil, which provides better high-frequency shielding.

[0110] Electromagnetic shielding can effectively prevent the propagation of electromagnetic interference of the driving component 403, ensure the normal operation and coordinated work of the diagnosis and treatment system, and improve the safety and reliability of the diagnosis and treatment process.

[0111] In some embodiments, see Figure 6 and combined Figure 10 The shared bed in this application also includes a first roller group 301 and a first guide rail 4011. The first roller group 301 is rotatably connected to the shared bed board 300. The first guide rail 4011 is provided on the driving platform 400. The first roller group 301 is rollingly connected to the first guide rail 4011.

[0112] In this way, the rolling connection between the first roller assembly 301 and the first guide rail 4011 has a significantly lower coefficient of rolling friction than sliding friction, making the shared bed board 300 more stable during movement and reducing vibration and noise. This also significantly reduces the resistance encountered by the shared bed board 300 during movement, making movement smoother and lighter. Patients will not experience noticeable lag or vibration while using the shared bed board 300, thus improving the user experience.

[0113] In addition, the first guide rail 4011 provides precise guidance for the first roller group 301, ensuring that the common bed board 300 moves according to the preset trajectory and direction under the action of the driving component 403, avoiding position deviation caused by uneven friction or other factors, and can more accurately deliver the patient to the position required for diagnosis and treatment, which is conducive to improving the accuracy of diagnosis and treatment.

[0114] In some embodiments, the first roller assembly 301 may be a plurality of rollers, and the plurality of rollers are rotatably connected to the surface of the common bed board 300 facing the driving platform 400 .

[0115] In other embodiments, the first roller group 301 includes multiple bearings and multiple bearing positioning shafts that cooperate with the bearings. The bearing positioning shafts are arranged on both sides of the common bed board 300, and one bearing can be rotatably sleeved on one bearing positioning shaft.

[0116] In some embodiments, see Figure 6 Combined with Figure 10 Taking the movement of the common bed board 300 along the length direction of the common bed board 300 as an example, the common bed in the present application also includes a second roller group 302 and a second guide rail 4012. The second roller group 302 is rotatably connected to the common bed board 300 and is spaced apart from the first roller group 301 along a direction perpendicular to the movement direction of the common bed board 300 (i.e., the width direction of the common bed board 300).

[0117] The second guide rail 4012 is arranged on the driving platform 400 and is spaced apart from the first guide rail 4011 along a direction perpendicular to the movement direction of the common bed board 300 (i.e., the width direction of the common bed board 300 ). The second roller group 302 is rollingly connected to the second guide rail 4012 .

[0118] It should be noted that in order to ensure the balance of the common bed board 300 during movement, the present application uses the structure of the second roller group 302 to be consistent with that of the first roller group 301. Therefore, the present application will not elaborate on the structure of the second roller group 302 and the second guide rail 4012.

[0119] Of course, the structures of the second roller set 302 and the first roller set 301 may also be different, as long as the stability and balance of the common bed board 300 can be guaranteed.

[0120] On this basis, this bilateral arrangement in the width direction of the shared bed board 300 can evenly share the weight of the shared bed board 300, and provide stable support in the lateral direction to prevent the shared bed board 300 from tilting, shaking, and other unstable situations. Each group of first roller groups 301 may include multiple rollers, which are arranged along the length of the bed board and work together to achieve smooth rolling of the bed board on the guide rails. The roller groups and guide rail groups on both sides work together to enable the shared bed board 300 to maintain a stable horizontal state when bearing a large load (such as a patient), and under the drive of the drive component 403, it moves accurately in the set direction and path.

[0121] In other embodiments, see Figure 6 and combined Figure 10 The second movable platform 202 is provided with a fourth guide rail 2021 and a fifth guide rail 2022. The fourth guide rail 2021 is used to dock with the first guide rail 4011, and the fifth guide rail 2022 is used to dock with the second guide rail 4012, so that the common bed board 300 can be smoothly moved to the second movable platform 202.

[0122] When the shared bed board 300 needs to be moved to the second mobile platform 202, the first guide rail 4011 guides the first roller assembly 301 connected to it gradually closer to the second mobile platform 202. As the positions continue to approach, the fourth guide rail 2021 and the first guide rail 4011 begin to contact and gradually align, ultimately achieving a seamless docking. After docking, the guiding effect of the first guide rail 4011 on the shared bed board 300 is continued through the fourth guide rail 2021, ensuring that the shared bed board 300 continues to move in the correct direction during the initial stage of entering the second mobile platform 202, avoiding deviation from the track or jamming.

[0123] During the movement of the shared bed board 300, the second guide rail 4012 and the fifth guide rail 2022 will also be precisely spliced ​​together like the fourth guide rail 2021 and the first guide rail 4011, and then jointly guide the shared bed board 300 to continue to move deeper into the second mobile platform 202, and cooperate from different directions on both sides to ensure the smooth movement of the shared bed board 300, further stabilize the position accuracy of the shared bed board 300 during the transfer process, and prevent it from tilting, shaking and other unstable phenomena until it is completely moved to the second mobile platform 202.

[0124] In some embodiments, see Figure 6 and combined Figure 11 The common bed board 300 in this application is provided with a matching piece, and a locking piece 2023 is provided at a preset position. The locking piece 2023 is used to lock the matching piece so that the common bed board 300 is fixed at the preset position.

[0125] When the preset position is the second movable platform 202, a locking piece 2023 is provided on the second movable platform 202, so that after the common bed board 300 is moved to the second movable platform 202, the position of the common bed board 300 can be fixed. Thus, through the fixing effect of the locking piece 2023 and the matching piece, it can be ensured that the common bed board 300 stays accurately in the predetermined position, avoiding deviation of the treatment area due to slight displacement of the common bed board 300 during radiotherapy, thereby ensuring the accuracy and effectiveness of the diagnosis and treatment operation.

[0126] In some embodiments, the mating part may be a clamping surface or clamping block installed on the edge or bottom of the common bed board 300, and the locking part 2023 may be a hydraulically or pneumatically driven clamping device. When the common bed board 300 reaches the preset position, the hydraulic or pneumatic system is started to drive the piston or push rod of the clamping device to move, so that the clamping block fits tightly with the clamping surface on the common bed board 300, and the common bed board 300 is fixed on the second mobile platform 202 by friction.

[0127] In some embodiments, see Figure 11 The locking member 2023 is an electromagnetic locking device, and the locking member 2023 is used to lock the matching member to fix the common bed board 300.

[0128] For example, the mating components are electromagnetic locks located on both sides of the shared bed board 300, and the mating component is a lock cylinder located on the second movable platform 202. The lock cylinder has two states: retracted and popped out. After the shared bed board 300 reaches a predetermined position, the lock cylinder pops out and cooperates with the electromagnetic lock to lock the shared bed board 300, thereby firmly fixing the shared bed board 300 to the second movable platform 202. When the shared bed board 300 needs to be released, the lock cylinder retracts again, the electromagnetic lock is powered off, and the shared bed board 300 can be unlocked and moved.

[0129] In other embodiments, the matching member is one of the positioning pin and the positioning hole, and the locking member 2023 is the other of the positioning pin and the positioning hole.

[0130] The positioning pins and positioning holes are respectively provided on the common bed board 300 and the second movable platform 202, and they cooperate with each other to play the role of preliminary positioning. When the common bed board 300 moves above the second movable platform 202, the positioning pins will accurately insert into the positioning holes to limit its displacement in the plane.

[0131] The connection between the common bed board 300 and the driving platform 400 in the present application is explained below.

[0132] In some embodiments, the common bed board 300 is directly connected to the screw 402, that is, the common bed board 300 is provided with a threaded hole, the common bed board 300 is sleeved on the screw 402, and the screw 402 cooperates with the threaded hole to drive the common bed board 300 to move when rotating.

[0133] In other embodiments, see Figure 9 Combined with Figure 12 The shared bed in this application also includes a nut 304, which is transmission-connected to the lead screw 402, and the nut 304 is connected to the shared bed board 300. The lead screw 402 drives the nut 304 to move to drive the shared bed board 300 to move axially along the lead screw 402.

[0134] When the drive assembly 403 rotates the lead screw 402, based on the principle of thread transmission, the rotational motion of the lead screw 402 is converted into linear motion of the nut 304. Since the nut 304 is fixedly connected to the common bed board 300, the nut 304 drives the common bed board 300 forward or backward along the axial direction of the lead screw 402.

[0135] In some embodiments, see Figure 9 Combined with Figure 12 The platform 401 in the present application is provided with a third guide rail 4013, and the common bed board 300 in the present application also includes a slider 305, which is slidably arranged between the third guide rail 4013 and the common bed board 300, and the slider 305 is transmission-connected to the lead screw 402. When the lead screw 402 rotates under the action of the driving device, the slider 305 will generate a linear motion along the axial direction of the lead screw 402 through thread transmission.

[0136] Also, see Figure 9 The common bed board 300 in the present application further includes a positioning block 306, which is connected to the slider 305. When the slider 305 generates a linear motion along the axial direction of the lead screw 402, it can drive the positioning block 306 to move. The positioning block 306 is arranged between the driving component 403 and the nut 304. When the nut 304 is separated from the lead screw 402 (see Figure 15 as well as Figure 16 ), the positioning block 306 is used to push the common bed board 300 to continue moving, so as to ensure that the matching parts of the common bed board 300 can smoothly cooperate with the locking part 2023.

[0137] When the lead screw 402 begins to rotate under the action of the drive assembly 403, based on the principle of threaded transmission, the slider 305 will move linearly along the axial direction of the lead screw 402. Due to the cooperation between the slider 305 and the third guide rail 4013, it will move smoothly along the guide rail. Under normal circumstances, the lead screw 402 drives the common bed board 300 through the nut 304. However, when the nut 304 disengages from the lead screw 402, the lead screw 402 continues to rotate and drives the slider 305 to move. The slider 305 also drives the positioning block 306 to move, which can push the common bed board 300 to continue moving along the predetermined path, ensuring that the common bed board 300 can move to the preset position, or ensuring that the common bed board 300 can engage with the locking member 2023 at the preset position.

[0138] In some embodiments, see Figure 11 and combined Figure 1 After the screw 402 rotates forward to drive the common bed board 300 to move to the preset position, the nut 304 disengages from the screw 402. An elastic pushing member 2024 is provided at the preset position. When the common bed board 300 is in the preset position, the elastic pushing member 2024 applies a pushing force toward the screw 402 to push the common bed board 300 toward the screw 402 to push the common bed board 300 toward the screw 402, so that the nut 304 docks with the screw 402, and the screw 402 reverses to move the nut 304 to the circumferential side of the screw 402.

[0139] For example, when the screw 402 rotates clockwise to drive the common bed board 300 toward a preset position, the screw 402 rotates forward. The screw 402, in conjunction with the threaded engagement of the nut 304, drives the common bed board 300 to move along the axial direction of the screw 402 toward the preset position. During this process, the rotational motion of the screw 402 is converted into linear motion of the nut 304 and the common bed board 300, allowing the common bed board 300 to accurately reach the predetermined position.

[0140] When the shared bed plate 300 moves to the preset position, the nut 304 disengages from the lead screw 402. At this point, the elastic pusher 2024 at the preset position begins to function. The elastic pusher 2024, which may be a spring, elastic rubber block, or other device with elastic restoring force, applies a force to the shared bed plate 300 toward the lead screw 402.

[0141] This pushing force causes the common bed plate 300 to produce a slight displacement toward the lead screw 402 , with the purpose of allowing the previously detached nut 304 to re-docking with the lead screw 402 .

[0142] After the nut 304 re-docking with the lead screw 402, the lead screw 402 begins to reverse. At this point, due to the threaded fit between the lead screw 402 and the nut 304, the reverse rotation of the lead screw 402 causes the nut 304 to move axially along the lead screw 402, ultimately moving to the circumference of the lead screw 402. This allows the lead screw 402 to quickly and accurately engage with the nut 304 the next time the shared bed board 300 needs to be driven, resuming movement of the shared bed board 300.

[0143] Exemplarily, the elastic pushing member 2024 may be a spring, and the second movable platform 202 is provided with a spring seat, in which the spring is disposed.

[0144] In other embodiments, a spring pressure block is further provided on the common bed board 300 to ensure that after the common bed board 300 moves to a preset position, it can generate pressure on the spring on the spring seat.

[0145] In combination with the above technical features, when the common bed board 300 moves to the preset position, the mating part and the locking part 2023 cooperate and lock, and the common bed board 300 will be fixed in the preset position. Therefore, although the elastic pushing part 2024 will generate a pushing force on the common bed board 300, the common bed board 300 will not move.

[0146] When the shared bed board 300 needs to be re-docked with the lead screw 402, the locking piece 2023 unlocks the mating piece, and under the action of the elastic pushing piece 2024, the elastic pushing block 303 can push the shared bed board 300 to re-docked with the lead screw 402, the lead screw 402 reverses, and the shared bed board 300 can return to its original position for the next use.

[0147] It can be understood that when the common bed board 300 moves to the second moving platform 202, the elastic pusher 2024 can apply an elastic force to the common bed board 300 along the negative direction of the Y-axis. As the moving target position of the common bed board 300 is different, the role played by the elastic force is also different. Therefore, for the sake of convenience of distinction, in this application, when the common bed board 300 needs to be fixed on the second moving platform 202, the force applied by the elastic pusher 2024 to the common bed board 300 in this application is the first elastic force; and when the common bed board 300 needs to be re-docking with the screw 402, the force applied by the elastic pusher 2024 is the second elastic force.

[0148] The purpose of the first elastic force: when the nut 304 connected to the common bed board 300 is disengaged from the lead screw 402, the first elastic force can push the common bed board 300 to make the nut 304 close to the lead screw 402. In this way, the lead screw 402 continues to rotate forward, and the positioning block 306 and the slider continue to move along the axial direction of the lead screw 402 until they can push the nut 304 to continue to move along the positive direction of the Y axis, thereby ensuring that the locking piece 2023 successfully locks the mating piece on the common bed board 300 to ensure that the common bed board 300 can be fixed on the second moving platform 202.

[0149] The purpose of the second elastic force: when the nut 304 connected to the common bed board 300 needs to be re-docked with the screw 402, after the locking piece 2023 unlocks the mating piece on the common bed board 300, the second elastic force can push the common bed board 300 to allow the nut 304 to be re-screwed into the screw 402. At this time, the screw 402 reverses, and the common bed board 300 can return to the driving platform 400 under the driving action of the screw 402.

[0150] In other embodiments, based on the above, it can be understood that the driving platform 400 in the present application can drive the common bed board 300 in two directions. Therefore, in this embodiment, the diagnosis and treatment system only includes the second mobile platform 202 corresponding to the radiotherapy equipment 200, and the imaging equipment 100 does not need to be equipped with the first mobile platform 102. The patient only needs to get on and off the bed at the second mobile platform 202.

[0151] In some embodiments, the lead screw 402 in the present application is a non-metallic lead screw 402 .

[0152] On the one hand, different imaging devices 100 have different sensitivities and compatibilities to metals. Using a non-metallic lead screw 402 can improve the compatibility of the device with various imaging technologies, enabling it to better adapt to various imaging needs.

[0153] On the other hand, during radiotherapy, the metal wire rod 402 can absorb and scatter the radiotherapy radiation, affecting the radiation dose distribution and therapeutic effect. In contrast, the non-metal wire rod 402 has minimal absorption and scattering effects on the radiation, ensuring that the radiation is accurately delivered to the tumor site according to the predetermined plan, thereby improving the accuracy and efficacy of radiotherapy.

[0154] In some embodiments, see Figure 13 and combined Figure 14In this application, patients can also get on and off the bed on the second movable platform 202 between the imaging device 100 and the radiotherapy device 200. In this way, the initial position of the shared bed board 300 is the second movable platform 202. When the patient moves onto the shared bed board 300 and imaging is required, the shared bed board 300 can be moved to the imaging position 101 under the action of the drive platform 400 (not shown in the figure). When radiotherapy is required, the drive platform 400 transports the shared bed board 300 to the second movable platform 202 for further transportation. This eliminates the need to set the sliding components of the drive platform 400 on the first movable platform 101, simplifies the structure, and further reduces costs.

[0155] The following will be based on Figure 1 The diagnosis and treatment system shown in the figure introduces the entire diagnosis and treatment process.

[0156] (1) Scanning imaging preparation.

[0157] Before the entire diagnosis and treatment process begins, the first mobile platform 102 drives the shared bed (i.e., the shared bed board 300 and the driving platform 400) down to the target position (i.e., the patient's upper and lower bed positions) to allow the patient to lie on the shared bed board 300. After the patient lies on the shared bed board 300 and preparations are complete, the first mobile platform 102 rises, driving the shared bed board 300 and the driving platform 400 up to the imaging height. The imaging device 100 is manually operated to position the positioning laser line approximately at the center of the tumor to locate the patient.

[0158] It should be noted that, in order to avoid interference of the second mobile platform 202 with the shared bed when imaging at the imaging position 101, the height of the second mobile platform 202 is lower than that of the imaging position 101. Furthermore, the second mobile platform 202 is lowered to its lowest position on the Y-axis.

[0159] (2) Scanning imaging process.

[0160] Once the patient is positioned, the diagnostic scan begins. Figure 3 Combined with Figure 4 The first mobile platform 102 is controlled to transport the shared bed (i.e., the shared bed board 300 and the driving platform 400) in the horizontal direction (i.e., the direction indicated by the Y axis in the figure) into the imaging position 101 to image the patient on the shared bed board 300. For example, the imaging device 100 can image the patient according to the determined scanning range and sequence.

[0161] (3) The shared bed board is ready for transfer.

[0162] See also Figure 5 Combined with Figure 6After the diagnostic scan is completed, the end of the shared bed plate 300 located on the imaging device 100 is moved along the positive direction of the Y axis to a position flush with the imaging device 100 main body under the action of the driving platform 400 or the first movable platform 102. Then, the second movable platform 202 rises along the Z axis until the fourth guide rail 2021 and the fifth guide rail 2022 thereon are flush with the first guide rail 4011 and the second guide rail 4012 on the driving platform 400. The driving platform 400 can then drive the shared bed plate 300 to move onto the second movable platform 202.

[0163] (4) The shared bed board is moved into a locked position.

[0164] See also Figure 6 、 Figure 7 as well as Figure 8 The driving component 403 drives the screw 402 to rotate (such as forward rotation), and the nut 304 connected to the screw 402 moves along the axial direction of the screw 402 (that is, the positive direction of the Y-axis), so that the nut 304 drives the common bed board 300 to move along the positive direction of the Y-axis toward the second movable platform 202, and the first roller group 301 and the second roller group 302 on the common bed board 300 move from the first guide rail 4011 and the second guide rail 4012 to the fourth guide rail 2021 and the fifth guide rail 2022.

[0165] See Figure 15 、 Figure 16 、 Figure 17 as well as Figure 18 , Figure 15 and Figure 16 This is a diagram illustrating the separation of the common bed board 300 and the lead screw 402. Figure 17 and Figure 18 This is a diagram illustrating that the positioning block 306 continues to push the common bed plate 300 to continue to move along the positive direction of the Y axis. When the common bed plate 300 moves to one end of the lead screw 402 along the positive direction of the Y axis (one end here refers to the end along the Y axis), Figure 5 The common bed plate 300 in the positive direction of the Y axis is located at the end of the lead screw 402 facing the second movable platform 102), that is, when the tail of the common bed plate 300 is pushed to the end of the lead screw 402, see Figure 15 and Figure 16 , the screw 402 is disengaged from the nut 304 of the common bed board 300. At this time, the elastic pusher 2024 on the second movable platform 202 is squeezed to generate elastic force, and the elastic pusher 2024 will give the common bed board 300 a reverse thrust toward the driving platform 400, so that the nut 304 can be close to the screw 402.

[0166] See also Figure 17 and Figure 18At this time, the screw 402 is continued to be driven to rotate (forward rotation), the positioning block 306 moves along the positive direction of the Y-axis, and can abut against the nut 304. The screw 402 is continued to be rotated, and the positioning block 306 can push the nut 304 along the positive direction of the Y-axis, thereby continuing to push the common bed board 300 forward. The elastic pushing member 2024 is squeezed until the common bed board 300 passes over the locking member 2023 (such as an electromagnetic lock). The locking member 2023 locks the matching member on the common bed board 300, that is, the lock core and the matching member are locked. When the lock core of the electromagnetic lock bounces up, the screw 402 stops rotating, thereby firmly fixing the common bed board 300 on the second movable platform 202, so that the common bed board 300 is in a locked state of the second movable platform 202.

[0167] Please combine Figure 15 and Figure 16 , Figure 15 and Figure 16 The common bed plate 300 and the lead screw 402 are separated from the illustration. Specifically, Figure 15 for Figure 7 A partial enlarged view of point A in the middle. Figure 16 for Figure 8 A partial enlarged view of point B in the middle.

[0168] (5) The shared bed is transferred to the treatment state.

[0169] When the shared bed 300 is locked on the second movable platform 202, the second movable platform 202 is manipulated to transport the shared bed 300 horizontally (i.e., in the positive direction of the Y-axis in the figure) into the radiotherapy position 201 to perform radiotherapy on the patient on the shared bed 300. For example, the radiotherapy device 200 utilizes high-energy radiation to irradiate tumors and other pathological tissues to achieve the purpose of treating the tumor.

[0170] Before starting the radiotherapy equipment 200 for radiotherapy, the driving assembly 403 of the driving platform 400 drives the screw 402 to reverse, and the positioning block 306 and the slider 305 connected to the screw 402 are retracted along the axial direction of the screw 402 (i.e., moving in the positive direction of the Y axis) (i.e., the positioning block 306 moves along the negative direction of the Y axis) until the end face of the positioning block 306 is flush with the end face of the screw 402 or retracts a certain distance (this application uses the end face of the positioning block 306 being flush with the end face of the screw 402 as an example), thereby preventing the positioning block 306 from affecting the nut 304 from being re-screwed into the screw 402. This will be further explained in the subsequent step (6).

[0171] (6) The shared bed board is moved from the radiotherapy position back to the upper and lower bed positions of the imaging equipment.

[0172] After the radiotherapy is completed, the second movable platform 202 drives the common bed board 300 to move out of the radiotherapy position 201, and the second movable platform 202 moves toward the driving platform 400 until the fourth guide rail 2021 and the fifth guide rail 2022 are aligned with the first guide rail 4011 and the second guide rail 4012 on the driving platform 400, so that the second movable platform 202 returns to the track aligned position, i.e., the position of the first movable platform 102 and the second movable platform 202 in the aforementioned (3) common bed board transfer preparation state.

[0173] The driving assembly 403 drives the screw 402 to rotate (such as forward rotation), and the positioning block 306 will continue to move toward the common bed board 300 until the positioning block 306 pushes the nut 304 of the common bed board 300 forward, and pressure will be generated on the elastic pushing member 2024 along the positive direction of the Y-axis (for example, the common bed board 300 pushes the elastic pushing member 0.5 mm along the positive direction of the Y-axis), so that the elastic pushing member 2024 can apply a force in the opposite direction to the common bed board 300 (that is, generate a second elastic force).

[0174] Then, the locking member 2023 (e.g., an electromagnetic lock) is controlled to operate, the lock cylinder retracts, and the shared bed board 300 is unlocked. The assembly 403 drives the lead screw 402 to rotate in the opposite direction, and the positioning block 306 retreats toward the first movable platform 102. Under the action of the second elastic force of the elastic pusher 2024, the shared bed board 300 also retreats, that is, moves toward the driving platform 400, until the nut 304 of the shared bed board 300 contacts the end face of the lead screw 402. The lead screw 402 continues to rotate in the opposite direction, and the positioning block 306 retreats another 10 mm. The lead screw 402 stops and adjusts its direction, such as to forward rotation (the adjustment method can be referred to above and will not be described in detail in this application). The lead screw 402 is screwed back into the nut 304 of the shared bed board 300 for diagnosis and treatment, and the shared bed board 300 is moved to its initial position on the driving platform 400. The lead screw 402 stops rotating.

[0175] Furthermore, the first mobile platform 102 drives the shared bed out of the imaging position 101 and returns to the above-mentioned imaging preparation position. The first mobile platform 102 drives the shared bed (i.e., the shared bed board 300 and the driving platform 400) to descend in the height direction to the target position (i.e., the patient's getting on and off the bed) so that the patient can get off the shared bed board 300.

[0176] Finally, this application takes the imaging device as an MR device as an example to introduce the adaptive radiotherapy workflow based on the diagnosis and treatment system. The workflow includes:

[0177] 1) After the patient completes the planning scan, a precise treatment plan is designed based on the acquired imaging data. This plan then undergoes a rigorous review process and is officially approved for implementation.

[0178] 2) The treatment is officially started. The patient is smoothly transported to the adaptive magnetic resonance radiation therapy room and pre-positioned on the scanning bed of the MR device after system integration. That is, the patient lies on the shared bed board 300 on the first mobile platform 102.

[0179] 3) The medical staff exits the treatment room and operates the MRI host computer (or central control console) to perform positioning and scanning imaging to obtain image data that meets the doctor's needs; this image data is then quickly and stably transmitted to the patient's TPS database; at the same time, the MRI scanning bed (i.e., the first mobile platform 102) returns to the transfer preparation position, and the drive platform 400 is started to initiate the transfer procedure of the shared bed board 300.

[0180] It should be noted that the shared bed needs to control the movement speed of the shared bed to effectively prevent the patient from being displaced due to improper speed, and to fully ensure the patient's safety and the accuracy of treatment.

[0181] 4) After TPS receives the image sequence obtained by the MRI scan, professionals quickly and accurately delineate the target area and critical organs. Subsequently, based on the target area, the target area, target point, and dose field data in the original plan are cleverly translated and integrated into the three-dimensional reconstruction space of the MRI image, and the MRI image coordinates are selected as position parameters to construct a new treatment plan model. Next, a comprehensive evaluation of this re-planned plan is carried out, and based on the various indicators presented during the evaluation process, the plan parameters are finely and carefully adjusted. This operation is repeated until satisfactory evaluation results are obtained in all aspects.

[0182] 5) The radiotherapy device 200 runs the data, and the patient receives treatment in the radiotherapy position 201.

[0183] 6) After the radiotherapy equipment 200 is finished running, the position of the bed can be further shared according to specific needs.

[0184] For example, after radiotherapy is completed, the common bed board 300 first returns to the initial position of the driving platform 400, and then follows the driving platform 400 to return to the patient's original position for getting on and off the bed.

[0185] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
