[0032] Radiotherapy is a tumor treatment method that mainly uses high-energy rays to kill or control the growth of cancer cells to achieve tumor treatment. During a complete treatment cycle, it is difficult to ensure that the radiation beam is accurately irradiated to the tumor due to factors such as positioning errors, human breathing, and changes in the shape, size, and position of the tumor itself. This will cause insufficient radiation beam exposure to the tumor tissue, leading to recurrence. At the same time, the normal tissue around the tumor will also be exposed to unnecessary radiation, resulting in reduced accuracy and poor efficacy of radiotherapy.
[0033] In order to improve the accuracy and efficacy of radiotherapy, Image-Guided Radiation Therapy (IGRT) came into being. IGRT can accurately locate the tumor by using various imaging technologies (such as CT, MRI, PET, ultrasound, etc.) to ensure that the radiation beam can accurately irradiate the tumor while minimizing damage to surrounding normal tissues.
[0034] In the radiotherapy process of tumors, multiple radiotherapy sessions are usually required. Before the first radiotherapy, an imaging device is needed to image the target object to be radiotherapy in order to obtain information such as the location, size, and morphology of the tumor, and a treatment plan is formulated based on the information obtained by the imaging device; then the radiotherapy device is controlled to perform radiotherapy on the tumor based on the treatment plan. In the subsequent treatment process, an imaging device is needed to image the target object to be radiotherapy again in order to obtain information such as the location, size, and morphology of the tumor, and the information obtained by the imaging device is compared with the information obtained by the imaging device during the previous radiotherapy process, and the treatment plan is revised based on the comparison results, and then the radiotherapy device is controlled to perform radiotherapy on the tumor based on the revised treatment plan.
[0035] In the related art, in order to reduce the space occupied by the imaging device and the radiotherapy device, the imaging device and the radiotherapy device are usually integrated into an integrated device. However, there is a large mutual interference between the imaging device and the radiotherapy device in the integrated device, resulting in poor imaging quality and radiotherapy effect. Separating the imaging device and the radiotherapy device can eliminate or weaken the mutual interference between the imaging device and the radiotherapy device, thereby improving the imaging quality and radiotherapy effect. However, during the transfer of the target object to be radiotherapy between the imaging device and the radiotherapy device, the body position of the target object is prone to change, resulting in deviations in the area irradiated by high-energy rays, thereby affecting the treatment effect.
[0036] Based on this, an embodiment of the present application provides a radiotherapy system for solving the problem in related technologies that the position of the target object is prone to change, causing deviations in the area irradiated by high-energy rays, thereby affecting the treatment effect.
[0037] In some embodiments, see Figure 1 The radiotherapy system 100 includes an imaging device 1, which is used to image a target object to be radiotherapy to obtain information such as the location, size, shape of the tumor and its relationship with surrounding normal tissues, and based on this information, a treatment plan can be formulated for the target object to perform radiotherapy on the target object. It should be noted that the target object can be a patient or a phantom simulating a patient.
[0038] Among them, the imaging device 1 can include at least one of an MRI (Magnetic Resonance Imaging) device, a CT (Computed Tomography) device, a PET (Positron Emission Tomography) device or other types of imaging devices, or a hybrid device of at least two of them, which can image the target object.
[0039] It should be noted that the MRI device is a medical device that uses strong magnetic fields and radio frequency waves to generate detailed images of the internal structure of the human body; the CT device is a medical device that uses X-rays to take cross-sectional images of the body from multiple angles; and the PET device is a medical device that generates images by imaging the distribution of radioactive tracers in the body.
[0040] It is understandable that the number of imaging devices 1 can be one or more, which can be selected according to actual conditions, and this application does not specifically limit this. When the number of imaging devices 1 is one, the imaging device 1 can be any one of an MRI device, a CT device, and a PET device; when the number of imaging devices 1 is multiple, the multiple imaging devices 1 can be at least two of the MRI device, the CT device, and the PET device, and the multiple imaging devices 1 can be arranged in sequence along a straight line.
[0041] For example, Figure 1 As shown, the imaging device 1 includes an imaging host 11 and an imaging support device 12. The imaging host 11 has an imaging area. The imaging host 11 can deliver an imaging radiation beam to the imaging area to image a target object in the imaging area; the imaging support device 12 can support the target object to be imaged in the imaging area.
[0042] See also Figure 1 The radiotherapy system 100 further includes a radiotherapy device 2, which can perform radiotherapy on the target object based on the treatment plan. Exemplarily, the radiotherapy device 2 is arranged on one side of the imaging device 1, for example, the radiotherapy device 2 can be arranged face to face, back to back, or in the same direction as the imaging device 1.
[0043] The radiotherapy equipment 2 may include at least one of an accelerator, a gamma knife, a proton radiotherapy equipment, a neutron radiotherapy equipment, an electron radiotherapy equipment and a heavy ion radiotherapy equipment, or a hybrid equipment of at least two of them.
[0044] It should be noted that accelerators mainly treat tumors by accelerating electrons or generating high-energy X-rays (photons), while gamma knives mainly treat tumors by generating gamma rays from a fixed cobalt-60 source.
[0045] It is understandable that the number of radiotherapy devices 2 can be one or more, and can be selected according to actual conditions, and this application does not make specific restrictions on this. In the case where the number of radiotherapy devices 2 is one, the radiotherapy device 2 can be any one of an accelerator, a gamma knife, a proton radiotherapy device, a neutron radiotherapy device, an electron radiotherapy device, and a heavy ion radiotherapy device, or a hybrid device of at least two of them; in the case where the number of radiotherapy devices 2 is multiple, the multiple radiotherapy devices 2 can be at least two of an accelerator, a gamma knife, a proton radiotherapy device, a neutron radiotherapy device, an electron radiotherapy device, and a heavy ion radiotherapy device, and the multiple radiotherapy devices 2 and the imaging device 1 can be arranged in sequence along a straight line.
[0046] For example, Figure 1As shown, the radiotherapy equipment 2 includes a radiotherapy main unit 21 and a radiotherapy support device 22. The radiotherapy main unit 21 has a radiotherapy area. The radiotherapy main unit 21 can deliver radiotherapy radiation beams to the radiotherapy area to perform radiotherapy on the target object in the radiotherapy area; the radiotherapy support device 22 can support the target object to receive radiotherapy in the radiotherapy area.
[0047] On this basis, the imaging host 11, the imaging support device 12, the radiotherapy host 21, and the radiotherapy support device 22 can be arranged in a straight line. For example, the imaging support device 12 is arranged on the side of the imaging host 11 away from the radiotherapy host 21, and the radiotherapy support device 22 is arranged between the imaging host 11 and the radiotherapy host 21. For another example, the imaging support device 12 is arranged on the side of the imaging host 11 away from the radiotherapy host 21, and the radiotherapy support device 22 is arranged on the side of the radiotherapy host 21 away from the imaging host 11. For another example, the imaging support device 12 is arranged between the imaging host 11 and the radiotherapy host 21, and the radiotherapy support device 22 is arranged on the side of the radiotherapy host 21 away from the imaging host 11.
[0048] See also Figure 1 The radiotherapy system 100 further includes a shared bed 3, which is arranged on at least one of the radiotherapy support device 22 and the imaging support device 12, and is used to automatically transfer the target object between the imaging device 1 and the radiotherapy device 2 during the radiotherapy process, so that the radiotherapy system 100 can be fully automatically operated after the target object is positioned. In this way, manual intervention can be reduced, thereby improving the treatment accuracy.
[0049] In addition, the imaging device 1 and the radiotherapy device 2 can be deeply integrated by sharing the bed 3, so that the imaging device 1 and the radiotherapy device 2 share a common coordinate system, that is, the imaging device 1 and the radiotherapy device 2 can perform imaging and radiotherapy on the target object based on the same coordinate system. In this way, the complexity of radiotherapy control can be simplified.
[0050] The following will provide an exemplary description of some implementations of a shared bed with reference to the accompanying drawings.
[0051] In some embodiments, see Figure 2 The shared bed 3 includes a shared bed board 31 and a bed board driving device 32. The bed board driving device 32 is connected to the shared bed board 31 and is arranged on at least one of the radiotherapy support device 22 and the imaging support device 12, and is used to drive the shared bed board 31 to move between the imaging area and the radiotherapy area in a straight line direction. The shared bed board 31 is used to support the target object to be radiotherapy.
[0052] In this way, when the bed board driving device 32 drives the common bed board 31 to move between the imaging area and the radiotherapy area, the target object on the common bed board 31 can be automatically transferred between the imaging device 1 and the radiotherapy device 2. In this way, the risk of the target object's position changing can be reduced, thereby improving the irradiation accuracy of high-energy rays and further improving the radiotherapy effect.
[0053] It should be noted that the present application does not impose any specific limitation on the structure and type of the bed board driving device 32 , as long as it can drive the common bed board 31 to move between the imaging area and the radiotherapy area in a straight line direction.
[0054] Some implementations of the bed board driving device 32 are exemplarily described below.
[0055] In some embodiments, the bed board driving device 32 includes a driving motor and a transmission assembly. The output shaft of the driving motor is connected to the common bed board 31 through the transmission assembly. The driving motor can drive the transmission assembly to move, thereby driving the common bed board 31 to move in a straight line direction between the imaging area and the radiotherapy area.
[0056] Among them, the transmission component can be a gear rack, screw drive, chain drive, synchronous belt drive, steel belt drive and other structures, which can be selected according to actual conditions, and this application does not make specific limitations on this.
[0057] In other embodiments, the bed board driving device 32 may be a linear motor, the output shaft of which is connected to the common bed board 31 , for driving the common bed board 31 to move between the imaging area and the radiotherapy area in a linear direction.
[0058] For the convenience of description, some embodiments of the present application will be exemplified below by taking the bed board driving device 32 used to drive the common bed board 31 to move between the imaging area and the radiotherapy area along the Y-axis direction as an example, wherein the Y-axis direction is a linear direction, for example, the Y-axis direction is the length direction of the common bed board 31.
[0059] In order to accurately irradiate the imaging radiation beam to the tumor and improve the imaging quality, see Figure 2 and Figure 3 The imaging support device 12 in the embodiment of the present application can be configured to drive the common bed 3 to move along at least one of the X-axis direction, the Y-axis direction and the Z-axis direction. 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 (gravity direction).
[0060] Exemplarily, the imaging support device 12 can drive the common bed 3 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction. That is, the imaging support device 12 can not only drive the common bed 3 to move along the X-axis direction, but also drive the common bed 3 to move along the Y-axis direction, and also drive the common bed 3 to move along the Z-axis direction.
[0061] In this way, the bed plate driving device 32 drives the common bed plate 31 to move along the Y-axis direction, and the imaging support device 12 drives the common bed 3 to move along the X-axis direction, the Y-axis direction and the Z-axis direction, so as to drive the target object on the common bed plate 31 to move along the X-axis direction, the Y-axis direction and the Z-axis direction, thereby adjusting the position of the target object in the imaging area. In this way, it is helpful to improve the irradiation accuracy of the imaging radiation beam, so that the imaging radiation beam can be accurately irradiated to the tumor. In this way, the imaging quality of the imaging device 1 can be improved.
[0062] In addition, the imaging support device 12 drives the shared bed 3 to move along the Z-axis direction, so as to adjust the height of the shared bed 3 so as to facilitate the target object to get on and off the bed.
[0063] It is understandable that there are various ways to enable the imaging support device 12 to drive the common bed 3 to move along the X-axis direction, the Y-axis direction and the Z-axis direction, which can be selected according to actual conditions, and the present application does not make specific limitations on this.
[0064] Some implementations of the imaging support device 12 are exemplarily described below.
[0065] In some embodiments, the imaging support device 12 includes an X-axis moving motor and an X-axis transmission mechanism. The output shaft of the X-axis moving motor is connected to the common bed 3 through the X-axis transmission mechanism. The X-axis moving motor can drive the X-axis transmission mechanism to move, thereby driving the common bed 3 to move along the X-axis direction.
[0066] Among them, the X-axis transmission mechanism can be a ball screw, a gear rack, a chain sprocket, a worm gear, a belt and other structures, which can be selected according to actual conditions, and this application does not make specific limitations on this.
[0067] The imaging support device 12 may also include a Y-axis moving motor and a Y-axis transmission mechanism. The output shaft of the Y-axis moving motor is connected to the common bed 3 through the Y-axis transmission mechanism. The Y-axis moving motor can drive the Y-axis transmission mechanism to move, thereby driving the common bed 3 to move along the Y-axis direction.
[0068] Among them, the Y-axis transmission mechanism can be a ball screw, gear rack, chain sprocket, worm gear, belt and other transmission mechanisms, which can be selected according to actual conditions, and this application does not make specific limitations on this.
[0069] The imaging support device 12 may also include a Z-axis moving motor and a Z-axis transmission mechanism. The output shaft of the Z-axis moving motor is connected to the common bed 3 through the Z-axis transmission mechanism. The Z-axis moving motor can drive the Z-axis transmission mechanism to move, thereby driving the common bed 3 to move along the Z-axis direction.
[0070] Among them, the Z-axis transmission mechanism can be a ball screw, gear rack, chain sprocket, worm gear, belt and other transmission mechanisms, which can be selected according to actual conditions, and this application does not make specific limitations on this.
[0071] In other embodiments, the imaging support device 12 is a robotic arm, which can drive the shared bed 3 to move along at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction. For example, the robotic arm can drive the shared bed 3 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction. The present application does not limit the specific structure of the robotic arm, which can be selected according to actual conditions.
[0072] In order to accurately irradiate the radiotherapy radiation beam onto the tumor, thereby improving the accuracy of radiotherapy and thus improving the treatment effect, the radiotherapy support device 22 in the embodiment of the present application can also be configured to be able to drive the common bed 3 to move along at least one of the X-axis direction, the Y-axis direction and the Z-axis direction.
[0073] Exemplarily, the radiotherapy support device 22 can drive the shared bed 3 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction. That is, the radiotherapy support device 22 can not only drive the shared bed 3 to move along the X-axis direction, but also drive the shared bed 3 to move along the Y-axis direction, and also drive the shared bed 3 to move along the Z-axis direction.
[0074] In this way, the common bed plate 31 can be driven to move along the Y-axis direction by the bed plate driving device 32, and the common bed 3 can be driven to move along the X-axis direction, the Y-axis direction and the Z-axis direction by the radiotherapy support device 22, so as to drive the target object on the common bed plate 31 to move along the X-axis direction, the Y-axis direction and the Z-axis direction, thereby adjusting the position of the target object in the radiotherapy area. In this way, it is helpful to improve the irradiation accuracy of the radiotherapy radiation beam, so that the radiotherapy radiation beam can be accurately irradiated to the tumor. In this way, the radiotherapy accuracy of the radiotherapy device 2 can be improved, thereby improving the treatment effect.
[0075] In addition, the radiotherapy support device 22 drives the shared bed 3 to move along the Z-axis direction, so as to adjust the height of the shared bed 3 so as to facilitate the target object to get on and off the bed.
[0076] It should be noted that in the embodiment of the present application, the radiotherapy support device 22 can adopt the same setting method as the above-mentioned imaging support device 12 to drive the common bed 3 to move along the X-axis direction, the Y-axis direction and the Z-axis direction; that is, the specific structure of the radiotherapy support device 22 can be designed with reference to the specific structure of the above-mentioned imaging support device 12, and this application will not go into details here.
[0077] To improve the automation level of the radiation therapy system 100, see Figure 4 The radiotherapy system 100 in the embodiment of the present application may further include a guide support device 4, wherein the guide support device 4, the imaging support device 12 and the radiotherapy support device 22 are connected to form an annular guide rail, and the shared bed 3 can move along the annular guide rail. In other words, the shared bed 3 can circulate along the annular guide rail.
[0078] The guide support device 4 can drive the shared bed 3 to move circularly along the circular guide rail; or the guide support device 4 can cooperate with at least one of the imaging support device 12 and the radiotherapy support device 22 to drive the shared bed 3 to move circularly along the circular guide rail. In this way, the shared bed 3 can be automatically moved along the circular guide rail.
[0079] In this way, in the radiotherapy process, after the target object is fixed on the common bed 3, without manual intervention, the common bed 3 can carry the target object and automatically move along the circular guide rail, so that the target object is automatically transferred between the imaging area and the radiotherapy area, thereby completing the complete radiotherapy process. In this way, the automation level of the radiotherapy system 100 can be improved, and the risk of the target object's position changing can be reduced, thereby improving the irradiation accuracy of the radiation beam, thereby improving the treatment accuracy and improving the treatment effect.
[0080] On this basis, in order to improve the utilization rate of the radiotherapy system 100 and shorten the waiting time of the target object, the number of shared beds 3 can be set to multiple. In this way, at the same time, different shared beds 3 can carry different target objects at different locations for different diagnosis and treatment processes.
[0081] For example, the number of shared beds 3 is 3. At the same time, one shared bed 3 can carry the target object for imaging at the imaging device 1, another shared bed 3 can carry the target object for radiotherapy at the radiotherapy device 2, and the last shared bed 3 can carry the target object for fixed positioning or release of fixed positioning on the upper and lower beds. In this way, the time for fixed positioning of the target object, the time for release of fixed positioning, and the time for radiotherapy can be parallelized, and the treatment rhythm of the target object can be reasonably planned to achieve the shortest comprehensive time, thereby improving the utilization rate of the radiotherapy system 100.
[0082] In order to reduce the mutual interference between the imaging host 11 and the radiotherapy host 21 to improve the effect of radiotherapy, the radiotherapy system 100 in the embodiment of the present application may also include an electromagnetic shielding structure, which is arranged between the imaging host 11 and the radiotherapy host 21 to block the transmission of electromagnetic waves between the imaging host 11 and the radiotherapy host 21.
[0083] In this way, the electromagnetic shielding structure can reduce the transmission of electromagnetic waves generated by the radiotherapy host 21 to the imaging host 11, thereby reducing the impact of the radiotherapy host 21 on the performance of the imaging host 11, thereby improving the imaging quality of the imaging host 11. At the same time, the electromagnetic shielding structure can also reduce the transmission of electromagnetic waves generated by the imaging host 11 to the radiotherapy host 21, thereby reducing the impact of the imaging host 11 on the performance of the radiotherapy host 21, thereby improving the radiotherapy accuracy of the radiotherapy host 21 and improving the effect of radiotherapy.
[0084] Some implementations of the electromagnetic shielding structure are exemplarily described below.
[0085] In some embodiments, the electromagnetic shielding structure has a through hole, and the through hole is used to allow the common bed plate 31 to pass through. In other words, the common bed plate 31 can be transferred between the imaging host 11 and the radiotherapy host 21 through the through hole on the electromagnetic shielding structure.
[0086] In other embodiments, the electromagnetic shielding structure can move between a shielding position and an avoidance position. When the electromagnetic shielding structure is in the shielding position, the electromagnetic shielding structure can block electromagnetic waves from being transmitted between the imaging host 11 and the radiotherapy host 21. When the electromagnetic shielding structure is in the avoidance position, the common bed board 31 can move between the imaging area and the radiotherapy area along the Y-axis direction.
[0087] In some other embodiments, the electromagnetic shielding structure can also be set in the form of a rolling door. When the common bed board 31 needs to be transferred between the imaging host 11 and the radiotherapy host 21, the electromagnetic shielding structure can be retracted to allow the common bed board 31 to pass through; after the common bed board 31 passes, the electromagnetic shielding structure can be lowered to block the transmission of electromagnetic waves between the imaging host 11 and the radiotherapy host 21.
[0088] In order to reduce the interference of the radiotherapy device 2 on the imaging device 1, the radiotherapy device 2 can also be configured to be movable so as to move the radiotherapy device 2 to a position offset from the imaging device 1 when the imaging device 1 is performing imaging.
[0089] Exemplarily, the radiotherapy equipment 2 can move between a first working position and a first avoidance position; wherein, when the radiotherapy equipment 2 is in the first working position, the bed board driving device 32 can drive the common bed board 31 to enter the radiotherapy area along the Y-axis direction to transfer the target object to the radiotherapy area for radiotherapy; when the radiotherapy equipment 2 is in the first avoidance position, along the Y-axis direction, the radiotherapy equipment 2 and the common bed 3 are staggered, and the radiotherapy equipment 2 is in a position staggered with the imaging equipment 1.
[0090] In this way, when the target object is imaged by the imaging device 1, the radiotherapy device 2 can be moved to the first avoidance position to increase the distance between the radiotherapy device 2 and the imaging device 1, thereby reducing the impact of the radiotherapy device 2 on the performance of the imaging device 1, and thus improving the imaging quality of the imaging device 1. When the radiotherapy device 2 is needed to perform radiotherapy on the target object, the radiotherapy device 2 can be moved to the first working position, and then the common bed plate 31 is driven by the bed plate driving device 32 to enter the radiotherapy area along the Y-axis direction, so as to transfer the target object to the radiotherapy area to receive radiotherapy from the radiotherapy device 2.
[0091] Similarly, in order to reduce the interference caused by the imaging device 1 to the radiotherapy device 2, the imaging device 1 can also be set to a movable form, so that the imaging device 1 can be moved to a position staggered with the radiotherapy device 2 when the radiotherapy device 2 performs radiotherapy.
[0092] Exemplarily, the imaging device 1 can move between a second working position and a second avoidance position; wherein, when the imaging device 1 is in the second working position, the bed board driving device 32 can drive the common bed board 31 to enter the imaging area along the Y-axis direction to transfer the target object to the imaging area for imaging; when the imaging device 1 is in the second avoidance position, along the Y-axis direction, the imaging device 1 and the common bed 3 are staggered, and the imaging device 1 is in a position staggered with the radiotherapy device 2.
[0093] In this way, when the target object receives radiotherapy from the radiotherapy device 2, the imaging device 1 can be moved to the second avoidance position to increase the distance between the radiotherapy device 2 and the imaging device 1, thereby reducing the impact of the imaging device 1 on the performance of the radiotherapy device 2, thereby improving the radiotherapy accuracy of the radiotherapy device 2. When the imaging device 1 is needed to image the target object, the imaging device 1 can be moved to the second working position, and then the common bed plate 31 is driven by the bed plate driving device 32 to enter the imaging area along the Y-axis direction, so as to transfer the target object to the imaging area to receive imaging from the imaging device 1.
[0094] In order to prevent technicians from being exposed to radiation during the radiotherapy process, in an embodiment of the present application, the radiotherapy host 21 and the imaging device 1 can be set in the treatment room; wherein, the equipment room is connected to the treatment room through an escape hole, and the escape hole is used to allow the common bed board 31 to pass through.
[0095] In this way, the target object can get in and out of the bed outside the clinic, and the technician can fix and release the target object outside the clinic without entering the clinic. In this way, the technician can be prevented from being exposed to radiation from the radiotherapy host 21 and the imaging host 11, thereby ensuring the personal safety of the technician.
[0096] This application does not specifically limit the location of the upper and lower shared beds of the target objects, and the specific location can be selected according to actual conditions.
[0097] The following will provide an exemplary description of the position of the upper and lower shared bed of the target object with reference to the accompanying drawings.
[0098] In some embodiments, see Figure 2 Along the Y-axis direction, the imaging support device 12 is arranged on the side of the imaging host 11 away from the radiotherapy equipment 2, that is, the imaging host 11 is arranged between the imaging support device 12 and the radiotherapy equipment 2.
[0099] On this basis, the bed board driving device 32 is used to drive the common bed board 31 to move between the first position and the radiotherapy area in a straight line direction. Alternatively, at least one of the radiotherapy support device 22 and the imaging support device 12 cooperates with the bed board driving device 32 to drive the common bed board 31 to move between the first position and the radiotherapy area in a straight line direction.
[0100] When the shared bed board 31 is in the first position, the shared bed board 31 is located on the side of the imaging host 11 close to the imaging support device 12, so that the target object can share the bed board 31 up and down. That is, the target object can share the bed 3 up and down at the imaging support device 12.
[0101] In order to facilitate the target object to share the bed 3 on the imaging support device 12, as shown in FIG. Figure 2 and Figure 5 As shown, the imaging support device 12 can be configured to drive the common bed 3 to move along the Z-axis direction, so as to adjust the height of the common bed 3 .
[0102] In other embodiments, see Figure 6 Along the Y-axis direction, the imaging support device 12 is arranged on the side of the imaging host 11 away from the radiotherapy equipment 2, and the radiotherapy support device 22 is arranged between the imaging host 11 and the radiotherapy host 21.
[0103] On this basis, the bed board driving device 32 is used to drive the common bed board 31 to move between the first position and the second position along a straight line. Alternatively, at least one of the radiotherapy support device 22 and the imaging support device 12 cooperates with the bed board driving device 32 to drive the common bed board 31 to move between the first position and the second position along a straight line.
[0104] Among them, when the common bed board 31 is in the first position, the common bed board 31 is located on the side of the imaging host 11 close to the imaging support device 12; when the common bed board 31 is in the second position, the common bed board 31 is located on the side of the radiotherapy host 21 away from the radiotherapy support device 22.
[0105] In this case, it can be that when the shared bed board 31 is in the first position, it is used to make the target object share the bed board 31 on the upper side; when the shared bed 3 is in the second position or between the imaging host 11 and the radiotherapy host 21, it is used to make the target object share the bed board 31 below. That is, the target object shares the bed 3 on the imaging support device 12, and shares the bed 3 under the radiotherapy support device 22 or the radiotherapy host 21 on the side away from the radiotherapy support device 22. It can also be that when the shared bed board 31 is in the first position, it is used to make the target object share the bed board 31 below; when the shared bed 3 is in the second position or between the imaging host 11 and the radiotherapy host 21, it is used to make the target object share the bed board 31 on the upper side. That is, the target object shares the bed 3 under the imaging support device 12, and shares the bed 3 on the side of the radiotherapy support device 22 or the radiotherapy host 21 away from the radiotherapy support device 22. The specific selection can be made according to the actual situation, and this application does not make any specific restrictions on this.
[0106] To facilitate the target to share the bed 3, see Figure 5 The imaging support device 12 can also be configured to drive the shared bed 3 to move along the Z-axis direction, and the radiotherapy support device 22 can be configured to drive the shared bed 3 to move along the Z-axis direction, so as to adjust the height of the shared bed 3.

[0108] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
