[0039] Radiation therapy is a tumor treatment method, which mainly uses high-energy rays to kill or control the growth of cancer cells to achieve the treatment of tumors.

[0040] At present, in the radiotherapy process of tumors, it is usually necessary to transfer the patient between multiple diagnosis and treatment devices to transport the patient into the diagnosis and treatment areas of different diagnosis and treatment devices to receive corresponding detection or treatment. For example, in the radiotherapy process of tumors, an imaging device is usually used to image the patient to obtain information such as the position, size and shape of the tumor, and a treatment plan is formulated according to the information obtained by the imaging device; then the patient is transferred to a radiotherapy device, and the radiotherapy device is controlled to perform radiotherapy on the tumor based on the treatment plan.

[0041] 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 great mutual interference between the imaging device and the radiotherapy device in the integrated device, resulting in poor imaging quality and radiotherapy effect. However, 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 the radiotherapy effect. However, during the transfer of the patient between multiple diagnosis and treatment devices, the body position of the patient is prone to change, resulting in deviation of the position of high-energy ray irradiation, and thus affecting the treatment effect.

[0042] Based on this, the embodiments of the application provide a diagnosis and treatment bed 1 for solving the problem that in the related art, the body position of the patient is prone to change, resulting in deviation of the position of high-energy ray irradiation, and thus affecting the treatment effect.

[0043] In some embodiments, referring to Figure 1 and Figure 2The diagnosis and treatment bed 1 comprises a base 11, a support plate 12, a bed plate 13 and a bed plate driving device. The support plate 12 is arranged on the base 11, and the base 11 can provide support for the support plate 12; the bed plate 13 is arranged on the support plate 12, and the bed plate 13 is used to carry a patient; the bed plate driving device is connected with the bed plate 13, and the bed plate driving device can drive the bed plate 13 to move along the Y-axis direction relative to the support plate 12, so that the bed plate 13 moves between the plurality of diagnosis and treatment devices 2.

[0044] In this way, the bed plate driving device can drive the bed plate 13 to move along the Y-axis direction between the plurality of diagnosis and treatment devices 2, thereby driving the patient on the bed plate 13 to automatically transfer between the plurality of diagnosis and treatment devices 2 along the Y-axis direction. In this way, in the radiotherapy process of the tumor, the risk of change of the patient's body position can be reduced, thereby improving the irradiation accuracy of the high-energy rays, and further improving the treatment effect.

[0045] It should be noted that the Y-axis direction is a straight line direction, for example, the Y-axis direction can be the length direction of the bed plate 13.

[0046] The structure and type of the bed plate driving device are not limited in the present application, as long as the bed plate 13 can be driven to move along the Y-axis direction relative to the support plate 12. Some implementation modes of the bed plate driving device will be exemplarily described below.

[0047] In some embodiments, the bed plate driving device comprises a Y-axis moving motor and a Y-axis transmission mechanism, the output shaft of the Y-axis moving motor is connected with the bed plate 13 through the Y-axis transmission mechanism, and the Y-axis moving motor can drive the Y-axis transmission mechanism to move, thereby driving the bed plate 13 to move along the Y-axis direction relative to the support plate 12.

[0048] The Y-axis transmission mechanism can be a gear and rack, a screw transmission, a chain transmission, a synchronous belt transmission, a steel belt transmission, etc., which can be selected according to actual conditions, and the present application does not make a specific limitation in this regard.

[0049] In other embodiments, the diagnosis and treatment bed 1 further comprises a plurality of rollers, and the plurality of rollers are rotatably connected with the bed plate 13; the side of the support plate 12 close to the bed plate 13 is provided with at least one sliding groove, and the sliding groove extends along the Y-axis direction; at least one roller is arranged in each sliding groove, and the roller can roll in the sliding groove.

[0050] On this basis, the bed plate driving device comprises a rotating motor, the output shaft of the rotating motor is connected with the at least one roller, and the rotating motor can drive the roller to roll in the sliding groove, thereby driving the bed plate 13 to move along the Y-axis direction relative to the support plate 12.

[0051] In other embodiments, the bed plate driving device can be a linear motor, the output shaft of the linear motor is connected with the bed plate 13, and the linear motor is used to drive the bed plate 13 to move along the Y-axis direction.

[0052] The specific structure of the base 11 is not limited in the embodiments of the present application, and can be designed according to actual conditions, as long as reliable support can be provided for the support plate 12.

[0053] In some embodiments, referring to Figure 1 , the base 11 includes a first support column 111 and a second support column 112, and the first support column 111 and the second support column 112 are arranged in the Y-axis direction. The first support column 111 and the second support column 112 are connected with the support plate 12 and used for supporting the support plate 12.

[0054] The first support column 111 and the second support column 112 can be arranged on the side of the support plate 12 away from the bed plate 13, for example, the bed plate 13 is arranged on the upper side of the support plate 12, and the first support column 111 and the second support column 112 are arranged on the lower side of the support plate 12.

[0055] In order to improve the stability of the structure of the base 11, so as to provide more reliable support for the support plate 12, the base 11 can further include a bottom plate 113, the bottom plate 113 is connected with the first support column 111 and the second support column 112, and used for connecting the first support column 111 and the second support column 112 as a whole, so as to prevent the first support column 111 and the second support column 112 from shaking.

[0056] For example, the bottom plate 113 is arranged opposite to the support plate 12, and the bottom plate 113 and the first support column 111 are arranged on the same side of the support plate 12 (for example, the bottom plate 113, the first support column 111 and the second support column 112 are all arranged on the lower side of the support plate 12).

[0057] In order to assist the patient in positioning, so that the radiation beam can accurately irradiate the tumor, thereby improving the treatment accuracy and improving the treatment effect, referring to Figure 1 , the diagnosis and treatment bed 1 in the embodiments of the present application can further include a support plate driving device 14, the support plate driving device 14 is arranged on the base 11 and connected with the support plate 12, and used for driving the support plate 12 to move relative to the base 11 in at least one of the X-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 (the direction of gravity).

[0058] For example, the support plate driving device 14 can drive the support plate 12 to move relative to the base 11 in the X-axis direction and the Z-axis direction, that is, the support plate driving device 14 can drive the support plate 12 to move relative to the base 11 in the X-axis direction, and can also drive the support plate 12 to move relative to the base 11 in the Z-axis direction.

[0059] In this way, the bed plate 13 can be driven to move along the Y-axis direction by the bed plate driving device to transfer the patient on the bed plate 13 into the treatment area of the treatment device 2, so that the radiation beam generated by the treatment device 2 irradiates the tumor area; then the support plate 12 is driven to move along the X-axis direction and the Z-axis direction by the support plate driving device 14 to drive the bed plate 13 and the patient on the bed plate 13 to move along the X-axis direction and the Z-axis direction, so as to adjust the position of the patient in the treatment area. In this way, the irradiation accuracy of the radiation beam can be improved, so that the radiation beam can accurately irradiate the tumor. In this way, the radiotherapy accuracy can be improved, and the radiotherapy effect can be improved.

[0060] It can be understood that there are various ways to drive the support plate 12 to move along the X-axis direction and the Z-axis direction by the support plate driving device 14, which can be selected according to actual conditions, and the present application does not make specific limitations.

[0061] Some implementation modes of the support plate driving device 14 will be exemplarily described below.

[0062] In some embodiments, referring to Figure 1 , the support plate driving device 14 includes a first driving assembly 141 and a second driving assembly 142, and the first driving assembly 141 can cooperate with the second driving assembly 142 to simultaneously drive the first support column 111 and the second support column 112 to move along at least one of the X-axis direction and the Z-axis direction.

[0063] For example, the first driving assembly 141 is used to drive the first support column 111 to move, the second driving assembly 142 is used to drive the second support column 112 to move, and the first driving assembly 141 and the second driving assembly 142 can be synchronously operated to simultaneously drive the first support column 111 and the second support column 112 to move along at least one of the X-axis direction and the Z-axis direction.

[0064] It can be understood that when the first driving assembly 141 and the second driving assembly 142 simultaneously drive the first support column 111 and the second support column 112 to move along the X-axis direction, the first support column 111 and the second support column 112 can drive the support plate 12 to synchronously move along the X-axis direction; similarly, when the first driving assembly 141 and the second driving assembly 142 simultaneously drive the first support column 111 and the second support column 112 to move along the Z-axis direction, the first support column 111 and the second support column 112 can drive the support plate 12 to synchronously move along the Z-axis direction. In this way, the support plate driving device 14 can drive the support plate 12 to move along the X-axis direction and the Z-axis direction.

[0065] In order to enable the first driving assembly 141 and the second driving assembly 142 to simultaneously drive the first support column 111 and the second support column 112 to move in at least one of the X-axis direction and the Z-axis direction, the first driving assembly 141 and the second driving assembly 142 can be arranged in the same structure, which facilitates the synchronous operation of the first driving assembly 141 and the second driving assembly 142, and in turn drives the first support column 111 and the second support column 112 to move synchronously.

[0066] The structure of the first driving assembly 141 will be exemplarily described below by taking the structure of the first driving assembly 141 and the second driving assembly 142 being the same as an example.

[0067] In some embodiments, the first driving assembly 141 comprises an X-axis moving motor and an X-axis transmission mechanism, an output shaft of the X-axis moving motor is connected with the first support column 111 through the X-axis transmission mechanism, and the X-axis moving motor can drive the X-axis transmission mechanism to move, and in turn drive the first support column 111 to move in the X-axis direction.

[0068] The X-axis transmission mechanism can be a gear and rack, a ball screw, a chain and sprocket, a worm and gear, etc., which can be selected according to actual conditions, and the present application does not make a specific limitation in this regard.

[0069] In addition, the first driving assembly 141 can further comprise a Z-axis moving motor and a Z-axis transmission mechanism, an output shaft of the Z-axis moving motor is connected with the first support column 111 through the Z-axis transmission mechanism, and the Z-axis moving motor can drive the Z-axis transmission mechanism to move, and in turn drive the first support column 111 to move in the Z-axis direction.

[0070] The Z-axis transmission mechanism can be a gear and rack, a ball screw, a chain and sprocket, a worm and gear, etc., which can be selected according to actual conditions, and the present application does not make a specific limitation in this regard.

[0071] Referring to Figure 1 and Figure 2 The present application further provides a diagnosis and treatment system 100, which comprises a plurality of diagnosis and treatment devices 2 and the diagnosis and treatment bed 1 in any one of the above embodiments, the plurality of diagnosis and treatment devices 2 are arranged in sequence along the Y-axis direction, and the bed plate driving device in the diagnosis and treatment bed 1 can drive the bed plate 13 to move relative to the support plate 12 in the Y-axis direction, so as to transfer the bed plate 13 between the plurality of diagnosis and treatment devices 2.

[0072] In this way, the automatic transfer of the patient between the plurality of diagnosis and treatment devices 2 can be realized through the diagnosis and treatment bed 1, thereby reducing the risk of the change of the patient's body position in the radiotherapy process of the tumor, and in turn improving the irradiation accuracy of the high-energy rays and the effect of the radiotherapy.

[0073] The plurality of diagnosis and treatment devices 2 can include an MR device 21 (magnetic resonance device) and a radiotherapy device 22. The MR device 21 can perform a positioning image scan on a patient. A treatment plan can be formulated for the patient based on a positioning image obtained by the MR device 21. The radiotherapy device 22 can perform radiotherapy on the patient based on the treatment plan.

[0074] It should be noted that the type of the radiotherapy device 22 is not limited in the present application. For example, the radiotherapy device 22 can include at least 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 mixed device of at least two of them.

[0075] The relative positions between the base 11 of the diagnosis and treatment bed 1 and the plurality of diagnosis and treatment devices 2 are not limited in the present application and can be designed according to actual conditions. For example, the plurality of diagnosis and treatment devices 2 are arranged on both sides of the first support column 111 and the second support column 112 of the base 11. For another example, at least one diagnosis and treatment device 2 is arranged between the first support column 111 and the second support column 112.

[0076] In some embodiments, referring to Figure 3 , the number of diagnosis and treatment devices 2 is two. The two diagnosis and treatment devices 2 are arranged face to face. The first support column 111 and the second support column 112 of the base 11 are arranged between the two diagnosis and treatment devices 2. The two diagnosis and treatment devices 2 can be an MR device 21 and a radiotherapy device 22, respectively.

[0077] In this case, the area between the MR device 21 and the radiotherapy device 22 can serve as an upper and lower bed for the patient to get on and off the diagnosis and treatment bed 1.

[0078] In the process of radiotherapy, the patient can get on the diagnosis and treatment bed 1 in the area between the MR device 21 and the radiotherapy device 22 and perform a simulation positioning. Then, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to send the patient into the MR device 21 for a positioning image scan. After that, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to send the patient into the radiotherapy device 22 for radiotherapy. After the radiotherapy, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to transfer the patient to the area between the MR device 21 and the radiotherapy device 22 to release the patient from the fixation constraint and make the patient get off the diagnosis and treatment bed 1.

[0079] In other embodiments, referring to Figure 4 , the number of diagnosis and treatment devices 2 is two. The two diagnosis and treatment devices 2 are arranged back to back. One diagnosis and treatment device 2 is arranged between the first support column 111 and the second support column 112 of the base 11. The other diagnosis and treatment device 2 is arranged on one side of the first support column 111 and the second support column 112. The two diagnosis and treatment devices 2 can be an MR device 21 and a radiotherapy device 22, respectively.

[0080] In this case, the side of the MR device 21 away from the diagnosis and treatment device 2 can be used as an upper bed position for the patient to get on the diagnosis and treatment bed 1, and the side of the diagnosis and treatment device 2 away from the MR device 21 can be used as a lower bed position for the patient to get off the diagnosis and treatment bed 1.

[0081] In the process of radiotherapy, the patient can get on the diagnosis and treatment bed 1 on the side of the MR device 21 away from the diagnosis and treatment device 2, and perform simulation positioning; then, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to send the patient into the MR device 21 for positioning image scanning. After that, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to send the patient into the radiotherapy device 22 for radiotherapy. After the radiotherapy is completed, the bed plate driving device drives the bed plate 13 to move along the Y-axis direction to transfer the patient to the side of the radiotherapy device 22 away from the MR device 21, to release the patient from the fixing constraint, and to make the patient get off the diagnosis and treatment bed 1.

[0082] In some embodiments, referring to Figure 5 , the diagnosis and treatment system 100 further comprises a diagnosis and treatment cabin 3, which comprises a cabin body 31 and a cabin door 32, the cabin door 32 is connected with the cabin body 31, and the cabin door 32 can move relative to the cabin body 31 to open or close the cabin body 31.

[0083] On this basis, referring to Figure 6 , a plurality of diagnosis and treatment devices 2 are arranged in the cabin body 31. In this case, the patient can enter the cabin body 31 through the cabin door 32 to receive radiotherapy.

[0084] In order to facilitate personnel access to the diagnosis and treatment cabin 3, the number of cabin doors 32 can be set to be multiple to realize personnel shunting. For example, the diagnosis and treatment cabin 3 comprises two diagnosis cabin doors 321 and two treatment cabin doors 322, the two diagnosis cabin doors 321 are oppositely arranged, and the two treatment cabin doors 322 are oppositely arranged.

[0085] Among them, the area in the cabin body 31 communicating with the two diagnosis cabin doors 321 is used to arrange the MR device 21, CT device and other devices that can provide high-quality diagnostic images; the area in the cabin body 31 communicating with the two treatment cabin doors 322 is used to arrange the radiotherapy device 22.

[0086] In order to avoid the situation that the wrong personnel enters the diagnosis and treatment cabin 3 and the wrong treatment information is retrieved, a face recognition system can also be arranged on the diagnosis and treatment cabin 3, which is used to detect the identity of the patient to be diagnosed to retrieve the patient's treatment information.

[0087] For example, if the human face recognition system confirms that the personnel identity is correct, the cabin door 32 is controlled to open to allow the personnel with the confirmed identity to enter the cabin body 31; if the personnel with the confirmed identity is a patient to be diagnosed, the treatment information of the patient is called to treat the patient. If the human face recognition system confirms that the personnel identity is incorrect, the cabin door 32 is controlled to close to refuse the personnel with the incorrect identity to enter the cabin body 31.

[0088] To improve the automation level of the diagnosis and treatment system 100, referring to Figure 1 and Figure 7 The diagnosis and treatment system 100 in the embodiment of the present application can further include a guide rail 4, one end of the guide rail 4 being connected with the first end of the support plate 12, the other end of the guide rail 4 being connected with the second end of the support plate 12, and the bed plate 13 being capable of moving along the extension direction of the guide rail 4 relative to the guide rail 4. Wherein, the first end and the second end of the support plate 12 refer to the two ends of the support plate 12 opposite to each other in the Y-axis direction.

[0089] In this case, the guide rail 4 and the support plate 12 can be connected to form a circulating track, and the bed plate 13 can move along the circulating track.

[0090] To enable the bed plate 13 to automatically run along the circulating track, to reduce manual intervention, and thus to improve the automation level of the diagnosis and treatment system 100, the diagnosis and treatment system 100 can further include a conveying device, the conveying device being connected with the guide rail 4 and capable of driving the bed plate 13 to move along the extension direction of the guide rail 4 relative to the guide rail 4.

[0091] On this basis, the conveying device can drive the bed plate 13 to move from the guide rail 4 to the support plate 12, and the bed plate driving device can drive the bed plate 13 to move from the support plate 12 to the guide rail 4. In this way, the transition of the bed plate 13 between the support plate 12 and the guide rail 4 can be realized.

[0092] In the radiotherapy process, the patient can be on the diagnosis and treatment bed 1, and the simulation positioning can be performed. Then, the bed plate driving device can drive the bed plate 13 to move along the Y-axis direction relative to the support plate 12 to transfer the patient between the plurality of diagnosis and treatment devices 2, to realize the radiotherapy of the patient. After that, the bed plate driving device can drive the bed plate 13 to move to the guide rail 4, and then the conveying device can drive the bed plate 13 to move along the guide rail 4 to convey the patient to the lower bed position, to release the patient from the fixed constraint, and to make the patient get off the diagnosis and treatment bed 1.

[0093] To improve the utilization rate of the diagnosis and treatment system 100 and shorten the waiting time of the patient, as shown in Figure 7 the number of the bed plates 13 can be set to be multiple. In this way, at the same time, different bed plates 13 can carry different patients to perform different diagnosis and treatment processes at different positions.

[0094] For example, the number of the bed plates 13 is three, at the same time, one bed plate 13 can carry the patient to perform the positioning image scan at the MR device 21, another bed plate 13 can carry the patient to perform the radiotherapy at the radiotherapy device 22, and the last bed plate 13 can carry the patient to perform the fixed positioning or the release positioning between the upper bed and the lower bed. In this way, the time of the fixed positioning of the patient, the time of the release positioning of the patient and the time of the radiotherapy can be parallel, the treatment rhythm of the patient can be reasonably planned, the integrated time is the shortest, and the utilization rate of the diagnosis and treatment system 100 is improved.

[0095] The diagnosis and treatment system in the embodiment of the application can meet the needs of the online adaptive radiotherapy, and provide the patient with high-quality, more accurate and more effective treatment effect. Taking the MR image guidance as an example, the adaptive radiotherapy process is introduced in detail.
