Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a shared bed and a diagnostic and treatment system. Background Technology

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

[0003] In terms of equipment setup, some technologies integrate imaging and radiotherapy equipment into one unit to save space. However, this approach has serious problems: the two devices interfere with each other strongly, resulting in poor image quality and significantly reduced radiotherapy effectiveness. Separating the two devices can reduce interference and improve imaging and radiotherapy effects, but it introduces new challenges. For example, when the patient is transferred between the imaging and radiotherapy equipment, their position is prone to change, affecting the treatment outcome.

[0004] This requires finding a balance between equipment layout and patient positioning. It is necessary to eliminate interference between equipment while ensuring patient stability, so as to achieve precise and effective radiotherapy, improve the success rate of tumor treatment, reduce treatment errors caused by changes in equipment layout and patient positioning, and provide patients with better medical services. Utility Model Content

[0005] The purpose of this application is to provide a shared bed and a treatment system that aims to solve the problem that changes in patient position during treatment can affect the treatment outcome.

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

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

[0008] Building upon this, the shared bed board in this application can be moved between different positions via a drive platform, providing a continuous support platform for the patient. Throughout the treatment process, the patient remains on the shared bed board, eliminating the need to change beds from imaging to radiotherapy, significantly reducing the risk of positional changes and further improving treatment accuracy.

[0009] Furthermore, the drive stage can precisely transfer the shared bed board along a preset path, thereby ensuring the stability of the patient's position during the process from the imaging position to the treatment position and preventing deviation of high-energy radiation irradiation due to changes in position.

[0010] Furthermore, the drive unit enables automated transfer of the shared bed board. While the patient is waiting (e.g., after imaging and while waiting for a treatment plan), the drive unit can automatically move the bed from the imaging equipment (first position) to the preset position on the radiotherapy equipment, making full use of the waiting time and avoiding errors from manual transfer. Its precise positioning function ensures that the shared bed board is accurately positioned during both imaging and radiotherapy, improving imaging accuracy and radiotherapy precision, and optimizing the entire treatment process.

[0011] Finally, from the patient's perspective, the entire process reduced patient discomfort. Patients did not need to frequently change beds or adjust their positions; they could simply lie quietly on the shared bed board and complete different stages of treatment in a comfortable and stable state. This alleviated anxiety, increased tolerance to treatment, and improved the patient experience, making it more conducive to the smooth progress of treatment.

[0012] In some embodiments, the drive table includes a table body, a lead screw, and a drive assembly. The lead screw is connected to the table body for transmission, and the drive assembly is disposed on the table body and connected to the lead screw for transmission. The drive assembly is used to drive the lead screw to rotate so that the common bed board moves relative to the drive table along a preset path.

[0013] In some embodiments, the drive assembly includes a servo motor, a drive pulley, a synchronous belt, and a driven pulley. The drive pulley is connected to the output end of the servo motor, which drives the drive pulley to rotate. A portion of the synchronous belt is wound around the drive pulley, and another portion is wound around the driven pulley. The output end of the driven pulley is connected to a lead screw. The drive pulley drives the driven pulley to rotate via the synchronous belt, thereby driving the lead screw to rotate.

[0014] In some embodiments, the shared bed in this application further includes a first roller assembly and a first guide rail. The first roller assembly is rotatably connected to the shared bed board, the first guide rail is disposed on the drive table, and the first roller assembly is rotatably connected to the first guide rail.

[0015] In some embodiments, the shared bed in this application further includes a second roller group and a second guide rail. The second roller group is rotatably connected to the shared bed board, and the second roller group and the first roller group are spaced apart in a direction perpendicular to the direction of movement of the shared bed board. The second guide rail is provided on the drive table, and the second guide rail and the first guide rail are spaced apart in a direction perpendicular to the direction of movement of the shared bed board. The second roller group is rotatably connected to the second guide rail.

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

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

[0018] In some embodiments, the platform is provided with a third guide rail. The common bed in this application also includes a nut, a slider, and a positioning block. The nut is connected to a lead screw and is also connected to the common bed plate. The lead screw drives the nut to move so that the common bed plate moves along the axial direction of the lead screw. The slider is slidably disposed between the third guide rail and the common bed plate and 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 so that the positioning block moves. The positioning block is disposed 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 plate to continue moving.

[0019] In some embodiments, after the lead screw drives the common bed board to a preset position, the nut disengages from the lead screw. An elastic pusher is provided at the preset position. When the common bed board is at the preset position, the elastic pusher applies a pushing force toward the lead screw to push the common bed board toward the lead screw so that the nut engages with the lead screw. The lead screw reverses to move the nut to the periphery of the lead screw.

[0020] Secondly, this application provides a diagnostic and treatment system, which includes a radiotherapy device, an imaging device, and the aforementioned shared bed. The radiotherapy device has a radiotherapy position, the imaging device is arranged opposite to the radiotherapy device and has an imaging position, and a drive stage is used to drive the shared 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 machine, a CT machine, and a PET machine.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

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

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

[0051] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0052] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

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

[0054] (1) Imaging equipment

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

[0056] The imaging methods of the 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, etc. This application uses magnetic resonance imaging as an example.

[0057] Magnetic resonance imaging (MRI) uses strong magnetic fields and radio frequency waves to induce resonance signals in hydrogen nuclei within the body. Differences in hydrogen atom signals in different tissues are captured by receiving coils and converted into images. MRI is generally suitable for fine 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 refers to a type of equipment that uses high-energy rays to irradiate diseased tissues such as tumors in order to treat diseases. Common radiotherapy equipment includes: medical linear accelerators, Gamma Knife, integrated radiotherapy equipment that combines a medical linear accelerator and Gamma Knife, and CyberKnife, among others.

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

[0061] Based on the above, in some embodiments, this application provides a diagnostic and treatment system, which includes an imaging device, a radiotherapy device, and a shared bed. This 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 unit 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 board 300 and a drive stage 400 for driving the shared bed board 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 a target object, such as a patient, located on a shared bed, and the radiotherapy position 201 is the position in the radiotherapy device 200 used to perform radiotherapy on a target object, such as a patient, located on a shared bed.

[0064] Based on the above-mentioned technical means, on the one hand, the radiotherapy system involved in this application does not require system integration that combines the imaging equipment and the radiotherapy equipment into one, thus avoiding huge costs. Instead, the shared bed board 300 is used to transfer the patient smoothly, accurately, and quickly between the imaging equipment 100 and the radiotherapy equipment by controlling the drive stage 400, ensuring that the patient's position on the imaging equipment and the radiotherapy equipment is completely consistent, improving the accuracy of radiotherapy, and enabling the radiation to irradiate the tumor target area more accurately.

[0065] On the other hand, the system in this application not only improves the adaptive radiotherapy function based on imaging equipment such as MRI, but also optimizes the diagnosis and treatment process, making it smoother and more efficient. For example, during the time after the patient is imaged and while waiting for radiotherapy (i.e., the time for adaptive adjustment of the treatment plan based on the images acquired by the imaging equipment), the shared bed is simultaneously and slowly moved automatically from the imaging position to the radiotherapy position. In this way, the patient can receive radiotherapy as soon as they arrive at the radiotherapy position, which greatly shortens the patient's radiotherapy waiting time, improves the efficiency of diagnosis and treatment, makes the entire adaptive process more compact, reduces the patient's stay time in the treatment room, and increases the turnover rate of the treatment room.

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

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

[0068] It should be noted that the application scenarios mentioned in this application are only one scenario in the actual application of shared beds. They can also be applied in other scenarios where needed, and this application does not limit them.

[0069] In some embodiments, the materials used in the diagnostic and treatment system of this application have properties such as radiation resistance, non-magnetic properties, and non-conductive properties. They can meet the requirements for ultraviolet light and chemical disinfection treatment.

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

[0071] It should be noted that, taking the example of the drive platform 400 driving the shared bed board 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 vice versa. The "preset position" can be either 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 that the shared bed board 300 needs to be transferred to, and the "preset path" can be the path that the shared bed board 300 needs to move to the corresponding target position.

[0072] The preset path can be a curve or a straight line. This application uses a straight line as an example for illustration.

[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., along the shared bed length). For example, the imaging device 100 and the radiotherapy device 200 are arranged at intervals in the same direction or at intervals in different directions along the positive direction of the Y-axis.

[0074] In other embodiments, please continue to refer to Figure 1 The imaging device 100 has a first moving platform 102, such as a diagnostic bed, on the side away from the radiotherapy device 200. The radiotherapy device 200 has a second moving platform 202, such as a radiotherapy bed, which is located between the imaging device 100 and the radiotherapy device 200.

[0075] In some embodiments, see Figure 3 and combined Figure 4 The shared bed in this application can be located on the first moving platform 102, which can move the shared bed in any of the X-axis, Y-axis, and Z-axis directions. The X-axis, Y-axis, and Z-axis are mutually perpendicular, and the Z-axis is parallel to the vertical direction (direction of gravity). For example, the coordinate system of the X-axis, Y-axis, and Z-axis is the IEC 61217 coordinate system, where the X-axis is the left-right direction (positive to the right); the Y-axis is the front-back direction (positive forward); and the Z-axis is the up-down direction (direction of gravity) (positive upward).

[0076] The first moving platform 102 is slidably connected to the drive stage 400, and the first moving platform 102 can drive the drive stage 400 and the common bed board 300 thereon to move at least along the positive direction of the Y-axis. At the same time, the drive stage 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, so that the common bed board 300 is transferred from the drive stage 400 to the second moving platform 202 (i.e., the preset position) of the radiotherapy equipment; and / or, the drive stage 400 can also be used to dock with the common bed board 300 and drive the common bed board 300 to move towards the drive stage 400 along the path (i.e., the preset path) between the imaging position 101 and the radiotherapy position 201, so that the common bed board 300 is transferred from the second moving platform 202 (i.e., the preset position) of the radiotherapy equipment to the drive stage.

[0077] In some embodiments, the first moving platform 102 is provided with a slide rail extending horizontally along the Y-axis, and the drive stage 400 is provided with a sliding block, which is slidably connected to the slide rail. In other embodiments, the first moving platform 102 is provided with a protrusion extending horizontally along the Y-axis, and the drive stage 400 is provided with a groove, which is slidably connected to the protrusion.

[0078] In some embodiments, the first mobile platform 102 is provided with a power component, which is connected to the drive platform 400 to drive the drive platform 400 to move along the positive or negative direction of the Y-axis. For example, the power component can be an electric telescopic rod. Yet another example is that the power component can be a hydraulic push rod.

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

[0080] In some embodiments, the first moving platform 102 is connected to a lifting assembly, which controls the position of the first moving platform 102 on the Z-axis, thereby enabling the first moving platform 102 to move the shared bed along the Z-axis. For example, the lifting assembly can be a hydraulic lifting platform. Another example is a guide rail type lifting platform.

[0081] In some embodiments, see Figure 7 and combined Figure 8 After the second moving platform 202 receives the common bed board 300, it can also drive the common 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 relationship between the first moving platform 102 and the drive stage 400, which will not be described in detail in this application.

[0082] In other embodiments, the shared bed in this application may also be disposed on the second moving platform 202, which is capable of moving the shared bed 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 is parallel to the vertical direction (the direction of gravity).

[0083] The second moving platform 202 is slidably connected to the drive stage 400. The second moving platform 202 can drive the drive stage 400 and the shared bed board 300 thereon to move at least along the positive or negative Y-axis. At the same time, the drive stage 400 can also drive the shared bed board 300 to move along the path between the imaging position 101 and the radiotherapy position 201 (i.e., the preset path) and disengage from the shared bed board 300, so that the shared bed board 300 is transferred from the drive stage 400 to the first moving platform 102 (i.e., the preset position) of the imaging device; and / or, the drive stage 400 can also be used to dock with the shared bed board 300 and drive the shared bed board 300 to move towards the drive stage 400 along the path between the imaging position 101 and the radiotherapy position 201 (i.e., the preset path), so that the shared bed board 300 is transferred from the first moving platform 202 (i.e., the preset position) of the imaging device 100 to the drive stage.

[0084] In some embodiments, the second moving platform 202 is provided with a slide rail extending horizontally along the Y-axis, and the drive stage 400 is provided with a sliding block, which is slidably connected to the slide rail. In other embodiments, the second moving platform 202 is provided with a protrusion extending horizontally along the Y-axis, and the drive stage 400 is provided with a groove, which is slidably connected to the protrusion.

[0085] In some embodiments, the second mobile platform 202 is provided with a power component, which is connected to the drive platform 400 via a transmission connection. The power component drives the drive platform 400 to move along the positive or negative Y-axis direction. For example, the power component can be an electric telescopic rod. Another example is a hydraulic push rod.

[0086] It should be noted that the movement of the shared bed by the second moving platform 202 in the X-axis direction can refer to the movement of the shared bed by the first moving platform 102 in the positive or negative Y-axis direction, and will not be elaborated upon in this application.

[0087] In some embodiments, the second mobile platform 202 is connected to a lifting assembly, which controls the position of the second mobile platform 202 on the Z-axis, thereby enabling the second mobile platform 202 to move the shared bed along the Z-axis. For example, the lifting assembly can be a hydraulic lifting platform. Another example is a guide rail type lifting platform.

[0088] In some embodiments, after the first moving platform 102 receives the common bed board 300, it can also drive the common bed to move in any positive or negative direction corresponding to the X-axis, Y-axis, and Z-axis. The specific connection method is the same as the connection relationship between the second moving platform 202 and the drive stage 400, which will not be described in detail in this application.

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

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

[0091] In some embodiments, the drive platform 400 can be an electric telescopic rod, which controls the movement of the shared bed board 300. Furthermore, the electric telescopic rod engages with the shared bed to achieve detachment and connection with the shared bed board 300.

[0092] In some embodiments, see Figure 5 , Figure 9 and combined Figure 10 The drive table 400 in this application may include a table body 401, a lead screw 402, and a drive assembly 403. The lead screw 402 is connected to the table body 401 in a transmission manner. The drive assembly 403 is disposed on the table body 401 and is connected to the lead screw 402 in a transmission manner. The drive assembly 403 is used to drive the lead screw 402 to rotate so that the common bed board 300 moves relative to the drive table 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 mounted on the first moving platform 102. The platform 401 serves as a relatively stable basic support for the entire structure, providing a basis for the installation and fixation of the lead screw 402. The lead screw 402 cooperates with the common bed board 300 and can drive it to make corresponding displacements.

[0095] The drive assembly 403 drives the lead screw 402 to rotate. When the lead screw 402 rotates, it exerts a force on the common bed board 300 to drive the common bed board 300 to move along a preset path (i.e., the axis of the lead screw 402).

[0096] Furthermore, the direction of movement of the common bed board 300 along the circumference of the lead screw 402 varies depending on the rotation direction of the lead screw 402. This application illustrates this by exemplifying that when the lead screw 402 rotates clockwise, it drives the common bed board 300 to move along the axial direction of the lead screw 402 towards the radiotherapy device 200. Correspondingly, when the lead screw 402 rotates counterclockwise, it can drive the common bed board 300 to move along the axial direction of the lead screw 402 away from the radiotherapy device 200.

[0097] Of course, during the above process, when the lead screw 402 rotates counterclockwise, it can also drive the common bed board 300 to move along the axis of the lead screw 402 and toward the radiotherapy device 200. Correspondingly, when the lead screw 402 rotates clockwise, it can drive the common bed board 300 to move along the axis of the lead screw 402 and away from the radiotherapy device 200. This application does not limit this. For ease of explanation, this application defines clockwise rotation of the lead screw 402 as forward rotation and counterclockwise rotation of the lead screw 402 as reverse rotation.

[0098] For example, please refer to the previous section. Figure 1 When the lead screw 402 rotates forward, it drives the common bed edge to move toward the radiotherapy equipment 200; when the lead screw 402 rotates in reverse, it drives the common bed edge to move toward the imaging equipment 100.

[0099] On the one hand, the lead screw 402 transmission has high precision, enabling precise control of minute displacements. In situations requiring fine-tuning of patient positioning, such as adjusting the position of the patient's head or limbs during scanning, the lead screw 402 transmission can precisely achieve these adjustments, meeting different scanning needs.

[0100] On the other hand, this application also allows for further adjustment of the patient's position at the imaging position 101 using the drive stage 400. By adjusting parameters such as the length and pitch of the lead screw 402, the movement stroke and speed of the common bed board 300 can be easily changed, enabling it to adapt to the imaging needs of different models of imaging equipment 100. For example, the movement range of the common bed board 300 can be flexibly adjusted to meet the requirements of patients of different body types or different scanning areas, thereby improving the versatility and adaptability of the equipment.

[0101] Furthermore, operators can control the movement of the shared bed board 300 simply by controlling the operation of the drive component 403. At the same time, the movement driven by the lead screw 402 is highly intuitive, allowing operators to accurately adjust the position of the shared bed board 300 according to actual needs, thus improving the ease of operation and work efficiency of the equipment.

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

[0103] In some embodiments, see Figure 9 and combined Figure 10 The drive 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 drive pulley 4032, a timing belt 4033, and a driven pulley 4034. The drive pulley 4032 is connected to the output end of a servo motor 4031, which drives the drive pulley 4032 to rotate. A portion of the timing belt 4033 is wound around the drive pulley 4032, and another portion is wound around the driven pulley 4034. The output end of the driven pulley 4034 is connected to a lead screw 402. The drive pulley 4032 drives the driven pulley 4034 to rotate via the timing belt 4033, thereby driving the lead screw 402 to rotate.

[0105] Under the action of the servo motor 4031, when the servo motor 4031 starts to rotate, its output shaft will drive the drive pulley 4032 to rotate synchronously. The drive pulley 4032 is like the starting "drive wheel" of the transmission system, transmitting the power generated by the servo motor 4031. The drive pulley 4032 transmits power to the driven pulley 4034 through the synchronous belt 4033. The driven pulley 4034 receives the power transmitted from the synchronous belt 4033, thereby driving the lead screw 402 to rotate.

[0106] The servo motor 4031 has high-precision position and speed control capabilities, which can precisely drive the active pulley 4032 to rotate, and transmit the rotation to the passive pulley 4034 via the synchronous belt 4033. Finally, it precisely controls the rotation of the lead 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 transmits smoothly, which can effectively reduce the vibration and noise generated when the shared bed board 300 moves, creating a comfortable environment for patients and ensuring stable operation of the equipment.

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

[0108] For example, the servo motor 4031 and the drive pulley 4032 are made of materials with good electromagnetic shielding properties. Sensitive electronic components and circuit sections are isolated using metal shielding on the control circuit board of the drive motor.

[0109] As another example, all the wires of the drive assembly 403 can be double-shielded electromagnetic wires. A double-shielded wire consists of two shielding layers and an intermediate insulating layer. The outer shielding layer is typically made of metal braided mesh or metal foil, which has high mechanical strength and good electromagnetic shielding performance; the inner shielding layer is generally made of tin-plated copper wire braided mesh or aluminum foil, which has better high-frequency shielding effect.

[0110] Electromagnetic shielding can effectively prevent the propagation of electromagnetic interference from the drive component 403, ensuring the normal operation and collaborative work of the diagnostic and treatment system, and improving the safety and reliability of the diagnostic 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 assembly 301 and a first guide rail 4011. The first roller assembly 301 is rotatably connected to the shared bed board 300, and the first guide rail 4011 is located on the drive platform 400. The first roller assembly 301 is rotatably connected to the first guide rail 4011.

[0112] In this way, the first roller assembly 301 and the first guide rail 4011 are connected by rolling friction. Compared with sliding friction, the coefficient of rolling friction is significantly smaller, making the shared bed board 300 more stable during movement and reducing vibration and noise. At the same time, it greatly reduces the resistance encountered by the shared bed board 300 during movement, making the movement smoother and lighter. Patients will not feel any obvious jamming or vibration on the shared bed board 300, thus improving the user experience.

[0113] Furthermore, the first guide rail 4011 provides precise guidance for the first roller group 301, ensuring that the common bed board 300 moves along the preset trajectory and direction under the action of the drive component 403, avoiding positional deviations 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 group 301 may be a plurality of rollers, which are rotatably connected to the surface of the common bed board 300 facing the drive table 400.

[0115] In other embodiments, the first roller assembly 301 includes a plurality of bearings and a plurality of bearing positioning shafts that cooperate with the bearings. The bearing positioning shafts are located on both sides of the common bed plate 300, and a bearing is rotatably mounted on a bearing positioning shaft.

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

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

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

[0119] Of course, the structure of the second roller group 302 and the first roller group 301 can be different, as long as the stability and balance of the shared bed board 300 can be guaranteed.

[0120] Based on this, the double-sided arrangement of the shared bed board 300 in the width direction can evenly distribute the weight of the shared bed board 300 and provide stable support in the lateral direction, preventing the shared bed board 300 from tilting, swaying, or other unstable situations. Each first roller group 301 may contain 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 rail. The combined action of the roller groups and guide rail groups on both sides allows the shared bed board 300 to maintain a stable horizontal state even when bearing a large load (such as a patient), and to move precisely according to the set direction and path under the drive of the drive component 403.

[0121] In other embodiments, see Figure 6 and combined Figure 10 The second mobile 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 onto the second mobile platform 202.

[0122] When the shared bed board 300 needs to move to the second moving platform 202, the first guide rail 4011 guides the first roller assembly 301 connected to it to gradually approach the second moving platform 202. As the position gets closer, the fourth guide rail 2021 and the first guide rail 4011 begin to contact and gradually align, ultimately achieving seamless docking. After docking, the guiding effect of the first guide rail 4011 on the shared bed board 300 is continued by the fourth guide rail 2021, allowing the shared bed board 300 to still move along the predetermined correct direction in the initial stage of entering the second moving 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 be precisely spliced ​​together, just as the fourth guide rail 2021 and the first guide rail 4011 are connected. Then, they will jointly guide the shared bed board 300 to continue to move deeper into the second moving platform 202. They will work together from different directions on both sides to ensure the stability of the movement of the shared bed board 300, further stabilize the positional accuracy of the shared bed board 300 during the transfer process, and prevent it from tilting, shaking or other unstable phenomena, until it is completely moved onto the second moving 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 mating part and a locking part 2023 is provided at a preset position. The locking part 2023 is used to lock the mating part so that the common bed board 300 is fixed at the preset position.

[0125] When the preset position is the second moving platform 202, the second moving platform 202 is provided with a locking member 2023 so that after the common bed board 300 moves to the second moving platform 202, the position of the common bed board 300 can be fixed. Thus, through the fixing action of the locking member 2023 and the mating member, it can be ensured that the common bed board 300 is accurately stopped in the predetermined position, avoiding deviation of the treatment area due to the 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 component can be a clamping surface or clamping block installed on the edge or bottom of the common bed board 300, and the locking component 2023 can be a hydraulically or pneumatically driven clamping device. When the common bed board 300 reaches the preset position, the hydraulic or pneumatic system is activated to drive the piston or push rod of the clamping device to move, so that the clamping block is tightly fitted with the clamping surface on the common bed board 300, and the common bed board 300 is fixed on the second moving platform 202 by friction.

[0127] In some embodiments, see Figure 11 The locking element 2023 is an electromagnetic locking device, which is used to lock the mating parts to fix the common bed board 300.

[0128] For example, the mating components are electromagnetic locks located on both sides of the common bed board 300, and a lock cylinder located on the second moving platform 202. The lock cylinder has two states: retracted and extended. After the common bed board 300 reaches the predetermined position, the lock cylinder extends and engages with the electromagnetic lock to lock the common bed board 300, thereby firmly fixing the common bed board 300 to the second moving platform 202. When it is necessary to release the common bed board 300, the lock cylinder retracts again, the electromagnetic lock is de-energized, and the common bed board 300 can be unlocked and moved.

[0129] In other embodiments, the mating component is one of a locating pin and a locating hole, and the locking component 2023 is the other of a locating pin and a locating hole.

[0130] Positioning pins and positioning holes are respectively installed on the common bed board 300 and the second moving platform 202, and they cooperate to perform a preliminary positioning function. When the common bed board 300 moves above the second moving 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 drive table 400 in this application is explained below.

[0132] In some embodiments, the common bed board 300 is directly connected to the lead screw 402. That is, the common bed board 300 is provided with a threaded hole, the common bed board 300 is sleeved on the lead screw 402, and the lead 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 and combined Figure 12 The shared bed in this application also includes a nut 304, which is connected to a lead screw 402 and is connected to a shared bed board 300. The lead screw 402 drives the nut 304 to move, thereby causing the shared bed board 300 to move along the axial direction of the lead screw 402.

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

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

[0136] Meanwhile, continue to see Figure 9 The common bed board 300 in this application also includes a positioning block 306, which is connected to the slider 305. When the slider 305 moves linearly along the axial direction of the lead screw 402, it can drive the positioning block 306 to move. The positioning block 306 is located between the drive assembly 403 and the nut 304. After the nut 304 disengages from the lead screw 402 (see [reference]), the positioning block 306 moves. Figure 15 as well as Figure 16 The positioning block 306 is used to push the common bed board 300 to continue moving so that the mating parts of the common bed board 300 can smoothly engage 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 plate 300 to move 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 drives the positioning block 306 to move together, which can push the common bed plate 300 to continue to move along the predetermined path, so as to ensure that the common bed plate 300 can move to the preset position, or to ensure that the common bed plate 300 is engaged with the locking member 2023 in the preset position.

[0138] In some embodiments, see Figure 11 and combined Figure 1 When the lead screw 402 rotates forward to drive the common bed plate 300 to move to the preset position, the nut 304 disengages from the lead screw 402. An elastic pusher 2024 is provided at the preset position. When the common bed plate 300 is in the preset position, the elastic pusher 2024 applies a pushing force toward the lead screw 402 to push the common bed plate 300 toward the lead screw 402 so that the nut 304 engages with the lead screw 402. The lead screw 402 rotates in reverse so that the nut 304 moves to the periphery of the lead screw 402.

[0139] Taking the clockwise rotation of the lead screw 402 driving the common bed plate 300 towards a preset position as an example, when the lead screw 402 rotates clockwise, it drives the common bed plate 300 to move along the axial direction of the lead screw 402 towards the preset position through the threaded engagement with the nut 304. In this process, the rotational motion of the lead screw 402 is converted into the linear motion of the nut 304 and the common bed plate 300, enabling the common bed plate 300 to accurately reach the predetermined position.

[0140] When the shared bed board 300 moves to the preset position, the nut 304 disengages from the lead screw 402. At this time, the elastic pusher 2024, which is set at the preset position, begins to function. The elastic pusher 2024 may be a spring, an elastic rubber block, or other device with elastic restoring force, which applies a pushing force to the shared bed board 300 in the direction of the lead screw 402.

[0141] This pushing force causes the common bed board 300 to shift slightly toward the lead screw 402, the purpose of which is to allow the previously dislodged nut 304 to reconnect with the lead screw 402.

[0142] After the nut 304 reconnects with the lead screw 402, the lead screw 402 begins to reverse. At this time, due to the threaded engagement between the lead screw 402 and the nut 304, the reversal of the lead screw 402 causes the nut 304 to move axially along the lead screw 402, eventually reaching the circumference of the lead screw 402. This ensures that the lead screw 402 can quickly and accurately engage with the nut 304 to restart the movement of the common bed plate 300 the next time it needs to be driven.

[0143] For example, the elastic pusher 2024 can be a spring, and the second moving platform 202 is provided with a spring seat, in which the spring is disposed.

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

[0145] Based on the above technical features, when the common bed board 300 moves to the preset position, the mating part and the locking part 2023 lock together and fix the common bed board 300 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 as a result.

[0146] When the shared bed board 300 needs to be reconnected with the lead screw 402, the locking part 2023 unlocks the mating part, and under the action of the elastic pusher 2024, the elastic pusher 303 can push the shared bed board 300 to reconnect with the lead screw 402. The lead screw 402 reverses, and the shared bed board 300 can return to the initial position for the next use.

[0147] It is understandable that when the shared bed board 300 moves to the second moving platform 202, the elastic pusher 2024 can apply an elastic force to the shared bed board 300 in the negative direction of the Y-axis. The effect of this elastic force varies depending on the target position of the shared bed board 300. Therefore, for ease of distinction, in this application, when the shared bed board 300 needs to be fixed on the second moving platform 202, the force applied by the elastic pusher 2024 to the shared bed board 300 is the first elastic force; while when the shared bed board 300 needs to be reconnected with the lead screw 402, the force applied by the elastic pusher 2024 is the second elastic force.

[0148] The purpose of the first elastic force is to push the common bed plate 300 so that the nut 304 connected to the common bed plate 300 is disengaged from the lead screw 402 when the nut 304 is disengaged from the lead screw 402. As a result, 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 the nut 304 can be pushed to continue to move in the positive direction of the Y axis. This ensures that the locking member 2023 successfully locks the mating member on the common bed plate 300, so as to ensure that the common bed plate 300 can be fixed on the second moving platform 202.

[0149] The purpose of the second elastic force is: when the nut 304 connected to the common bed plate 300 needs to be reconnected with the lead screw 402, after the locking member 2023 unlocks the mating part on the common bed plate 300, the second elastic force can push the common bed plate 300 so that the nut 304 is screwed back into the lead screw 402. At this time, the lead screw 402 reverses, and the common bed plate 300 can return to the drive table 400 under the driving action of the lead screw 402.

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

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

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

[0153] On the other hand, during radiotherapy, the metal wire rod 402 can cause interference such as absorption and scattering of radiotherapy rays, affecting the dose distribution and therapeutic effect. In contrast, the non-metal wire rod 402 has minimal absorption and scattering effect on radiotherapy rays, ensuring that the radiotherapy rays accurately irradiate the tumor site according to the predetermined plan, thus improving the precision 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 moving 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 moving platform 202. When the patient moves onto the shared bed board 300 and imaging is required, the shared bed board 300 can move to the imaging position 101 under the action of the drive stage 400 (not shown in the figure). When radiotherapy is required, the drive stage 400 transports the shared bed board 300 to the second moving platform 202 for further transport. This eliminates the need for a sliding component of the drive stage 400 on the first moving platform 101, simplifying the structure and further reducing costs.

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

[0156] (1) Preparation for scanning imaging.

[0157] Before the entire diagnostic and treatment process begins, the first mobile platform 102 lowers the shared bed (i.e., the shared bed board 300 and the drive platform 400) vertically to the target position (i.e., the patient's bed-up and down position) so that the patient can lie on the shared bed board 300. After the patient is lying on the shared bed board 300 and ready, the first mobile platform 102 rises to raise the shared bed board 300 and the drive platform 400 vertically to the imaging height. The imaging device 100 is then manually operated to roughly locate the patient in the center of the tumor using a positioning laser line.

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

[0159] (2) Scanning and imaging process.

[0160] Once the patient is located, the diagnostic scanning imaging process begins. (See below) Figure 3 and combined Figure 4 The first moving platform 102 is manipulated to transport the shared bed (i.e., the shared bed board 300 and the drive stage 400) along the horizontal direction (i.e., the direction shown 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 a determined scanning range and sequence.

[0161] (3) Shared bed board transfer preparation status.

[0162] See Figure 5 and combined Figure 6After the diagnostic scan is completed, the common bed board 300 on the imaging device 100 moves along the positive Y-axis to a position flush with the main unit of the imaging device 100 under the action of the drive stage 400 or the first moving platform 102. Then, the second moving platform 202 rises along the Z-axis until the fourth guide rail 2021 and the fifth guide rail 2022 on it are flush with the first guide rail 4011 and the second guide rail 4012 on the drive stage 400. The drive stage 400 can then drive the common bed board 300 to move onto the second moving platform 202.

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

[0164] See Figure 6 , Figure 7 as well as Figure 8 The drive assembly 403 drives the lead screw 402 to rotate (e.g., rotate in the forward direction). The nut 304, which is connected to the lead screw 402, moves along the axial direction of the lead screw 402 (i.e., the positive direction of the Y-axis). Thus, the nut 304 drives the common bed plate 300 to move towards the second moving platform 202 along the positive direction of the Y-axis. The first roller group 301 and the second roller group 302 on the common bed plate 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] Please see Figure 15 , Figure 16 , Figure 17 as well as Figure 18 , Figure 15 and Figure 16 The diagram illustrates the separation of the shared bed board 300 from the lead screw 402. Figure 17 and Figure 18 This illustration shows the continued movement of the common bed plate 300 along the positive Y-axis as the positioning block 306 continues to advance. When the common bed plate 300 moves along the positive Y-axis to one end of the lead screw 402 (here, "one end" refers to the end along the positive Y-axis),... Figure 5 The common bed board 300 in the positive direction of the Y-axis is located at the end of the lead screw 402 facing the second moving platform 102, that is, when the tail of the common bed board 300 is pushed to the end of the lead screw 402, see Figure 15 and Figure 16 When the lead screw 402 disengages from the nut 304 of the common bed board 300, the elastic pusher 2024 on the second moving platform 202 is compressed and generates elastic force. The elastic pusher 2024 will give the common bed board 300 a reverse thrust toward the drive table 400 so that the nut 304 can be tightly attached to the lead screw 402.

[0166] See Figure 17 and Figure 18At this point, the lead screw 402 continues to rotate (forward rotation), and the positioning block 306 moves along the positive direction of the Y-axis, abutting against the nut 304. As the lead screw 402 continues to rotate, the positioning block 306 pushes the nut 304 along the positive direction of the Y-axis, thereby pushing the common bed plate 300 forward. The elastic pusher 2024 is squeezed until the common bed plate 300 passes the locking member 2023 (such as an electromagnetic lock). The locking member 2023 locks the mating parts on the common bed plate 300, that is, the lock cylinder locks the mating parts. When the lock cylinder of the electromagnetic lock pops up, the lead screw 402 stops rotating, thereby firmly fixing the common bed plate 300 on the second moving platform 202, so that the common bed plate 300 is in the locked state of the second moving platform 202.

[0167] Please combine Figure 15 and Figure 16 , Figure 15 and Figure 16 The diagram illustrates the separation of the shared bed board 300 from the lead screw 402. Specifically, Figure 15 for Figure 7 A magnified view of a portion of point A in the middle. Figure 16 for Figure 8 A magnified view of a section at point B.

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

[0169] When the shared bed board 300 is locked on the second moving platform 202, the second moving platform 202 is manipulated to transport the shared bed board 300 into the radiotherapy position 201 along the horizontal direction (i.e., the positive direction of the Y-axis in the figure) to perform radiotherapy on the patient on the shared bed board 300. For example, the radiotherapy equipment 200 uses high-energy rays to irradiate diseased tissues such as tumors to achieve the purpose of treating tumors.

[0170] Before starting the radiotherapy equipment 200 for radiotherapy, the drive assembly 403 of the drive stage 400 drives the lead screw 402 to reverse. The positioning block 306 and the slider 305, which are connected to the lead screw 402, retract along the axial direction of the lead screw 402 (i.e., 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 lead screw 402 or retracts a certain distance (this application uses the example of the end face of the positioning block 306 being flush with the end face of the lead screw 402) to avoid the positioning block 306 affecting the nut 304 to be screwed back into the lead screw 402. This will be further explained in the subsequent step (6).

[0171] (6) The shared bed board is used to move from the radiotherapy position to the imaging equipment position.

[0172] After the radiotherapy is completed, the second moving platform 202 moves the shared bed board 300 out of the radiotherapy position 201. The second moving platform 202 moves towards the drive table 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 drive table 400. Thus, the second moving platform 202 returns to the aligned position, which is the position of the first moving platform 102 and the second moving platform 202 in the aforementioned (3) shared bed board transfer preparation state.

[0173] The drive assembly 403 drives the lead screw 402 to rotate (e.g., in the forward direction), and the positioning block 306 continues to move toward the common bed board 300 until the positioning block 306 pushes the nut 304 of the common bed board 300 forward, which will exert pressure on the elastic pusher 2024 in the positive direction of the Y-axis (exemplarily, the common bed board 300 pushes the elastic pusher 0.5mm in the positive direction of the Y-axis), so that the elastic pusher 2024 can apply a force in the opposite direction to the common bed board 300 (i.e., generate a second elastic force).

[0174] Then, the locking element 2023 (such as an electromagnetic lock) is activated, the lock cylinder retracts, and the common bed board 300 is unlocked. Component 403 drives the lead screw 402 to rotate in the opposite direction, the positioning block 306 moves backward toward the first moving platform 102, and the common bed board 300 also moves backward under the action of the second elastic force of the elastic pusher 2024, that is, it moves toward the drive table 400 until the nut 304 of the common bed board 300 contacts the end face of the lead screw 402. The lead screw 402 continues to rotate in the opposite direction, the positioning block 306 moves backward another 10mm, the lead screw 402 stops and adjusts its direction of rotation, such as turning forward (the adjustment method can be referred to above, which will not be repeated in this application). The lead screw 402 re-screws into the nut 304 of the treatment common bed board 300, moving the common bed board 300 to its initial position on the drive table 400, and the lead screw 402 stops rotating.

[0175] Furthermore, the first moving platform 102 drives the shared bed out of the imaging position 101 and back to the aforementioned imaging preparation position. The first moving platform 102 then drives the shared bed (i.e., the shared bed board 300 and the drive platform 400) to descend along the height direction to the target position (i.e., the patient getting on and off the bed position) so that the patient can get off the shared bed board 300.

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

[0177] 1) After the patient completes the planned localization scan, a precise treatment plan is designed based on the acquired image data. Subsequently, the treatment plan successfully passed a rigorous review process and finally received formal approval, and is about to enter the implementation phase.

[0178] 2) Treatment officially begins. The patient is smoothly transferred to the MRI adaptive radiotherapy room and pre-positioned on the MR equipment scanning bed after system integration. That is, the patient lies on the common bed board 300 on the first moving platform 102.

[0179] 3) Medical staff leave the treatment room, operate the MRI host computer (or central control console), and carry out positioning and scanning imaging work 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 moving platform 102) returns to the transfer preparation position, and the drive stage 400 is started to initiate the transfer procedure of the shared bed board 300.

[0180] It should be noted that the movement speed of the shared bed needs to be controlled to effectively prevent the patient from shifting due to improper speed, thus ensuring the safety of the patient and the accuracy of the treatment in all aspects.

[0181] 4) After receiving the image sequence obtained from the MRI scan, the TPS specialists quickly and accurately delineate the target area and critical organs. Then, using the target area as a reference, the originally planned target area, target points, and dose field data are skillfully translated and integrated into the three-dimensional reconstruction space of the MRI image. The MRI image coordinates are selected as positional parameters to construct a completely new treatment plan model. Next, a comprehensive evaluation of this redesigned plan is conducted. Based on the various indicators presented during the evaluation, the plan parameters are finely and carefully adjusted. This process is repeated until a satisfactory evaluation result is obtained in all aspects.

[0182] 5) The radiotherapy equipment 200 runs this data, and the patient receives treatment at the radiotherapy site 201.

[0183] 6) After the radiotherapy equipment 200 is completed, the location of the shared bed will be further determined according to specific needs.

[0184] For example, after radiotherapy, the shared bed board 300 first returns to the initial position of the drive platform 400, and then follows the drive platform 400 back to the patient's initial position when getting out of bed.

[0185] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
