Description

Technical Field

[0001] The present invention belongs to the technical field related to radiation delivery equipment, and in particular, relates to a radiotherapy device, a radiation delivery method and a computer-readable storage medium. Background Art

[0002] Radiation therapy, also known as "radiotherapy", is the treatment of malignant tumors and some benign diseases using one or more types of ionizing radiation.

[0003] At present, the existing radiotherapy scheme usually uses a linear accelerator to generate the required beam, and uses a rotatable gantry (such as a C-arm, slip ring or hospital bed) to achieve multi-angle irradiation of the tumor. Although the above scheme can achieve irradiation of the tumor at different angles, the rotatable gantry is not only large in size, but also has high construction and subsequent maintenance costs. It also needs to be used in a special treatment room equipped with a radiation shielding effect, which will further increase the cost. Summary of the invention

[0004] In view of this, it is necessary to provide a radiotherapy device, a radiation delivery method and a computer-readable storage medium for solving the above-mentioned technical problems.

[0005] A radiotherapy device, comprising:

[0006] A shielding cabin capable of shielding radiation, wherein a treatment chamber is disposed in the shielding cabin; and

[0007] The radiation delivery device can be movably accommodated in the shielding cabin, and the radiation delivery device can generate treatment radiation and emit the treatment radiation toward a target position in the treatment chamber.

[0008] It can be understood that the radiation delivery device that generates treatment radiation is housed in the treatment chamber, and the radiation is shielded by a shielding cabin. In this way, it is possible to avoid setting up the entire room where the radiotherapy device is placed as a treatment radiation shield, thereby reducing costs. At the same time, the position of the radiation delivery device relative to the shielding cabin is adjusted to achieve the injection of treatment radiation into the target position at different angles. In this way, on the one hand, the volume required to meet the multi-angle irradiation of treatment radiation can be reduced and the cost can be reduced. On the other hand, the distance between the radiation delivery device and the target position can be made smaller, thereby further improving the therapeutic effect of the radiotherapy device during radiotherapy.

[0009] In one embodiment, the radiotherapy device includes a movable guide rail, which is disposed in the shielding cabin and can move along the length direction of the treatment chamber;

[0010] The radiation delivery device is connected to the movable guide rail and is movable around the treatment chamber along the movable guide rail.

[0011] In one embodiment, the radiation delivery device includes a housing and a radiation generating system, wherein the radiation generating system is disposed in the housing and is capable of generating and emitting the treatment radiation;

[0012] Wherein, the shell is installed on the movable guide rail, and the ray generating system can adjust the emission angle of the treatment ray.

[0013] In one embodiment, the ray generating system comprises:

[0014] an electron beam generator for generating an electron beam;

[0015] an electron beam accelerator, used for accelerating the electron beam from the electron beam generator;

[0016] a target assembly for generating the treatment ray using an accelerated electron beam; and

[0017] The multi-leaf grating is used to adjust the beam shape of the treatment ray.

[0018] In one of the embodiments, the shielding cabin body includes a shielding cabin and a shielding cabin door, the shielding cabin door is slidably installed on the shielding cabin, and the shielding cabin door can be enclosed with the shielding cabin to form the treatment chamber.

[0019] In one embodiment, the radiotherapy device further includes an imaging module, and the imaging module is used to acquire an image of the target object in the target position.

[0020] It can be understood that the imaging module can be used to perform image guidance on the operation of the radiation delivery device, thereby achieving real-time monitoring and guidance of the target object in the target position, thereby improving the accuracy of irradiation of the target object in the target position when the radiation delivery device is working, so as to prevent damage to normal tissues and organs around the target object.

[0021] In one embodiment, the imaging module is disposed at a position orthogonal to the radiation delivery device relative to the target location.

[0022] It can be understood that the imaging module is arranged at an orthogonal position to the radiation delivery device, so as to avoid interference of the treatment radiation generated by the radiation delivery device with the imaging module.

[0023] In one embodiment, the imaging module can be adjusted relative to the treatment chamber synchronously with the radiation delivery device.

[0024] The present application also claims a radiation delivery method, comprising:

[0025] Treatment radiation is delivered to a target position in a treatment chamber in the shielding cabin by using a radiation delivery device movably housed in the shielding cabin, and the shielding cabin is capable of shielding radiation.

[0026] The present application also claims protection for a computer-readable storage medium having instructions stored thereon, which implement the above-mentioned radiation delivery method when executed by a processor.

[0027] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0028] The radiotherapy device, radiation delivery method and computer-readable storage medium of the present invention house the radiation delivery device that generates treatment radiation in a treatment chamber, and use a shielding cabin to shield the treatment radiation. This avoids setting up the entire room where the radiotherapy device is placed for treatment radiation shielding, thereby reducing costs. At the same time, the position of the radiation delivery device relative to the shielding cabin is adjusted to achieve the injection of treatment radiation into the target position at different angles. This can, on the one hand, reduce the volume required to meet multi-angle irradiation of treatment radiation and reduce costs. On the other hand, it can make the distance between the radiation delivery device and the target position smaller, thereby further improving the therapeutic effect of the radiotherapy device during radiotherapy.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that when an element is referred to as being "provided on" another element, it may be directly provided on the other element or there may be a central element. When an element is considered to be "provided on" another element, it may be directly provided on the other element or there may be a central element at the same time. When an element is considered to be "fixed to" another element, it may be directly fixed to the other element or there may be a central element at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] The radiotherapy device 100 for which protection is sought in the present application can be used to generate and deliver treatment rays that can be applied to various types of treatments such as radiotherapy, radiographic inspection or radiation testing. As an example, the treatment rays may include photon beams (X-rays, gamma rays, etc.), electron beams (low-energy electron beams, medium-energy electron beams, high-energy electron beams, etc.), fast neutron beams, proton beams, negative pion beams, and other heavy particle beams, etc. In addition, although the “radiotherapy device” is used as an example for explanation herein, it can be recognized that the device can be used not only for treatments related to radiotherapy, but also for various other types of treatments, such as radiation flaw detection for components, radiation processing for products, etc. Therefore, the expression “radiotherapy device” is not used to limit the function and use of the device.

[0038] like Figure 1As shown, a radiotherapy device 100 according to an embodiment of the present application includes a shielding cabin 10 and a radiation delivery device 20. A treatment chamber 101 may be provided in the shielding cabin 10. The shielding cabin 10 can shield radiation. As a non-limiting example, the radiation that can be shielded by the shielding cabin 10 includes one or more of various radiation rays such as treatment radiation generated by the radiation delivery device 20, ionizing radiation or non-ionizing radiation generated by internal equipment of the radiotherapy device 100 (e.g., the radiation delivery device 20 itself) or external equipment (e.g., a radiation source outside the radiotherapy device 100). The radiation delivery device 20 can be movably accommodated in the shielding cabin 10. When working, the radiation delivery device 20 can generate treatment radiation and emit the treatment radiation toward a target position (not shown) in the treatment chamber 101. The radiation delivery device 20 can adjust its position relative to the treatment chamber 101. In this way, the treatment radiation can be injected into the target position at different angles.

[0039] It can be understood that the radiation delivery device 20 that generates treatment radiation is housed in the shielding cabin 10, and the shielding cabin 10 is used to shield the radiation. For example, the shielding cabin 10 can shield the radiation generated in the shielding cabin 10 from the outside of the shielding cabin 10. Alternatively or additionally, the shielding cabin 10 can shield the radiation and rays generated outside the shielding cabin 10 from the treatment chamber 101 in the shielding cabin 10. In this way, for example, it can be avoided to set up the entire room where the radiotherapy device 100 is placed as a radiation shield, which has the effect of reducing costs. In addition, by adjusting the position of the radiation delivery device 20 relative to the shielding cabin 10, the radiation can be delivered to the target position at different angles. In this way, on the one hand, the volume required to meet the multi-angle irradiation treatment radiation can be reduced and the cost can be reduced. On the other hand, the distance between the radiation delivery device 20 and the target position can be made smaller, which has the effect of further improving the treatment effect of the radiotherapy device 100 during radiotherapy.

[0040] It should be noted that the target position refers to the position where irradiation or delivery is desired. As a non-limiting example, the target position may be an isocenter position, a specific volume around an isocenter, or a number of discrete point positions. As a specific example, the target position may include a region of interest (ROI), for example, the position of a tumor or other lesion in the body of the object 200 acted upon by the radiotherapy device 100 when working, that is, the radiotherapy device 100 can accurately irradiate the tumor or lesion when working, and achieve the purpose of radiotherapy. In addition, the target position may also be the position of various other living or non-living bodies. As an example, the target position may be a position on an irradiated experimental object (e.g., a dose verification phantom, an experimental small animal, a dose tester), etc. As a non-limiting example, a photon beam may be directed to a target position, thereby enabling the photon beam to reach this target position, thereby performing radiotherapy, inspection or testing on the object or target object.

[0041] As can be seen from the above, the shielding cabin 10 can be used to accommodate the object 200, and the object 200 can be irradiated with radiation in the shielding cabin 10. When the radiotherapy device 100 is working, the installation position can be changed according to the needs of radiotherapy of the object 200, so that the object 200 can be accommodated in the shielding cabin 10 in a supine or standing treatment position to improve the comfort of the object 200 in the treatment chamber 101. The object 200 can be various living or non-living objects. As an example, the object 200 can be a patient who needs radiotherapy, a phantom for dose verification, an animal for radiotherapy experiments, and the like. As a non-limiting example, the length of the treatment chamber 101 can be less than 5 meters, less than 6 meters, between 2.2 meters and 5 meters, between 2.5 meters and 3 meters, or between 2 meters and 3 meters, and the like. As non-limiting examples, the cross-sectional area of ​​the treatment chamber 101 may be less than 3 square meters, less than 10 square meters, less than 12 square meters, between 0.8 square meters and 2 square meters, between 0.5 square meters and 3 square meters, between 0.9 and 1.5 square meters, between 1 square meter and 3 square meters, or between 1.2 square meters and 2.9 square meters, etc. For example, the smaller the size of the treatment chamber 101, the smaller the occupied space of the shielding cabin 10 can be set, but the more stringent the size requirements for the object 200 are, and the lower the comfort level is when the object 200 is a patient. Therefore, the size of the treatment chamber 101 can be set according to actual requirements or needs.

[0042] like Figure 1 As shown, in some embodiments, the shielding cabin body 10 may include a shielding cabin 11 and a shielding cabin door 12, the shielding cabin door 12 may be slidably mounted on the shielding cabin 11, and the shielding cabin door 12 may be enclosed with the shielding cabin 11 to form a treatment chamber 101, so that the object 200 may enter the shielding cabin 11 after the shielding cabin door 12 is opened, and then the shielding cabin door 12 is automatically or manually covered on the shielding cabin 11, so that the object 200 may enter the treatment chamber 101. It should be noted that the working principle of the shielding cabin door 12 realizing automatic opening and closing on the shielding cabin 11 may adopt an automated system control method. The shielding cabin door 12 may also be set independently of the shielding cabin 11, and the shielding cabin door 12 may be opened and closed by an external manipulator by grasping and placing the shielding cabin door 12.

[0043] It can be understood that, for example, the shielding cabin 11 and the shielding door 12 of the shielding cabin 10 can be made of materials with a relatively large atomic number (e.g., lead, tungsten, cobalt or alloys thereof, etc.) so that the shielding cabin 10 has a self-shielding function. However, it is not limited thereto, and the shielding cabin 11 and the shielding door 12 of the shielding cabin 10 can be made of any other material capable of providing a shielding function, such as some composite materials, graphite, glass, rubber, plastic, etc., having shielding properties.

[0044] like Figure 1 , Figure 2 As shown, in some embodiments, the radiotherapy device 100 may include a movable rail 30. The movable rail 30 may be disposed in the treatment chamber 101. The movable rail 30 may be disposed in the shielding cabin 11 of the shielding cabin 10. For example, the movable rail 30 may be disposed around the treatment chamber 101. The movable rail 30 can move relative to the treatment chamber 101 along the length direction of the shielding cabin 10. In addition, for example, the radiation delivery device 20 can move around the treatment chamber 101 along the movable rail 30. It should be noted that the "movement along the movable rail 30" mentioned here can include not only the case where the radiation delivery device 20 moves relative to the movable rail 30, but also the case where the radiation delivery device 20 is fixed relative to the movable rail 30 but the movable rail 30 moves. As an example, the radiation delivery device 20 may be movably connected to the movable rail 30, and can move the treatment chamber 101 around the movable rail 30 (for example, circular motion or spiral motion). As another example, the radiation delivery device 20 may be fixedly connected to the movable guide rail 30, and the movable guide rail 30 may perform a circumferential motion (e.g., a circular motion or a spiral motion) relative to the treatment chamber 101, thereby driving the radiation delivery device 20 to perform a circumferential motion relative to the treatment chamber 101. The radiation delivery device 20 is installed in the shielding cabin 10 via the movable guide rail 30, and may be moved along the length direction of the treatment chamber 101. Alternatively or additionally, it may be able to move around the treatment chamber 101, thereby achieving the purpose of changing the position of the radiation delivery device 20 relative to the object 200 in the shielding cabin 10. Figure 1 , Figure 2 The movable guide rail 30 is shown as an exemplary structure of a circular ring, but the movable guide rail 30 can also be set to a hexagonal, square, or diamond shape. The working principle of the movable guide rail 30 moving along the treatment chamber 101 in the treatment chamber 101 and the working principle of how to achieve the circular motion of the radiation delivery device 20 on the movable guide rail 30 are not elaborated here because they are not the focus of the protection of this application.

[0045] Exemplarily, the radiation delivery device 20 can perform circular motion around the object 200 along the movable guide rail 30 alone, or perform linear motion along the body direction of the object 200 alone, or perform a spiral motion combining the two, with respect to a target object at a target position of the object 200 (for example, a patient's tumor tissue, a tissue or organ of interest in an animal's body, or other target object), until the radiation generated by the radiation delivery device 20 when it is working can be injected into the target object at different angles, thereby achieving radiotherapy for the target object.

[0046] The applicant wishes to point out that although Figure 1 , Figure 2The case where the moving rail 30 is disposed outside the treatment chamber 101 is shown, but the moving rail may also be disposed inside the treatment chamber 101 or on a side wall portion of the treatment chamber 101. In these cases, the moving rail 30 may perform a circular motion relative to the object 200 or the target position, and may alternatively or additionally move along the length direction of the treatment chamber 101.

[0047] like Figure 3 As shown, in some embodiments, the radiation delivery device 20 includes a shell 21 and a radiation generating system 22. The radiation generating system 22 can be disposed in the shell 21 and can generate and emit treatment radiation. The shell 21 can be mounted on a movable guide rail 30, and the radiation generating system 22 can adjust the emission angle of the treatment radiation. As another example, the shell 21 is fixedly mounted on the movable guide rail 30, and a part or all of the radiation generating system 22 can swing to adjust the radiation emission angle. In other words, the radiation delivery device 20 can generate radiation at an angle when it is in operation that can be adaptively adjusted according to the use requirements of radiotherapy, so that all-round irradiation of the target position can be achieved. It should be noted that the angle and direction of the swing here can be arbitrarily set as needed without limitation.

[0048] In some embodiments, for example, in the case where the radiation delivery device 20 delivers a photon beam, the radiation generating system 22 may include an electron beam generator 221, an electron beam accelerator 222, a target assembly 223, and a multi-leaf grating 224. The electron beam generator 221 may be used to generate an electron beam. The electron beam accelerator 222 may be used to receive and accelerate the electron beam from the electron beam generator 221. The target assembly 223 may be used to generate radiation (e.g., bremsstrahlung or other types of radiation) using the accelerated electron beam from the electron beam accelerator 222 to form a photon beam. The multi-leaf grating 224 may be used to adjust the beam shape of the photon beam from the target assembly 223. For example, the multi-leaf grating 224 may be used to conform the photon beam to match the shape of an area to be treated (e.g., a lesion, a radiotherapy test area, or other area) at a target location. Optionally, the radiation generating system 22 may further include a load 227. It should be noted that, when the radiation delivery device 20 delivers other types of treatment radiation, the radiation generation system 22 may be adaptively set to other configurations or structures. For example, when the radiation generation system 22 delivers electron beams, the radiation generation system 22 may not include a target assembly and a multi-leaf collimator.

[0049] In some embodiments, the electron beam generator 221 may include an electron gun, which can emit an electron beam toward the electron beam accelerator 222 when in operation. It should be noted that the electron beam generator 221 is not limited to an electron gun, and those skilled in the art may configure the electron beam generator 221 to be other devices capable of generating electron beams, such as an electron transmitter, an electron diode, etc.

[0050] In some embodiments, the electron beam accelerator 222 can be configured as a linear accelerator tube, which can specifically rotate a high-gradient, high-frequency technical route to reduce the volume required when the linear accelerator tube is working to accelerate the electron beam to a high-energy electron beam that meets the requirements of radiotherapy. It should be noted that the number of linear accelerator tubes is not limited to one, and of course, the electron beam accelerator 222 is not limited to a linear accelerator tube. For those skilled in the art, the electron beam can also be accelerated by cyclotron acceleration, and then cooperated with a magnetic deflection member to guide the high-energy electron beam drawn by the electron beam accelerator 222 to enter the target assembly 223.

[0051] In addition, it should be noted that the ray generating system 22 may also include a microwave power source 225 and a microwave transmission system 226 to meet the needs of the ray generating system 22 when it is working. For example, the microwave power source 225 and the microwave transmission system 226 may feed energy to the electron beam accelerator 222 for accelerating the electron beam.

[0052] In some embodiments, the radiotherapy device 100 also includes an imaging module 40, which can be used to obtain images at the target position (including near the target position). As an example, the radiation delivery device 20 can change its position according to the image obtained by the imaging module 40 so that the radiation generated by the radiation delivery device 20 is directed toward the desired position. In other words, the imaging module 40 can be used to guide the operation of the radiation delivery device 20 by image guidance, so that real-time monitoring and guidance of the target area in the target position can be achieved, thereby improving the accuracy of irradiating the target object at the target position when the radiation delivery device 20 is working, so as to prevent damage to normal tissues and organs around the target object. As a non-limiting example, the imaging module 40 and the radiation delivery device 20 are respectively connected by signal, and the controller is used to control the position change of the radiation delivery device 20. However, without limitation to this, the radiation delivery device 20 can also use other methods to change its position according to the image of the target object in the target position obtained by the imaging module 40.

[0053] Exemplarily, the imaging module 40 is configured as various imaging devices such as a treatment ray imaging device, an electronic portal imaging device (EPID), a cone beam computed tomography device, and the like.

[0054] In some embodiments, part or all of the imaging module 40 can be arranged at an orthogonal position to the radiation delivery device 20. The imaging module 40 can be adjusted relative to the shielding cabin 10 synchronously with the radiation delivery device 20, so that the imaging module 40 can be ensured to be always located at an orthogonal position to the radiation delivery device 20, so that the radiation generated by the radiation delivery device 20 during operation will not irradiate the imaging module 40, thereby avoiding interference with the operation of the imaging module 40. It should be noted that, optionally, see Figure 2 The imaging module 40 may be disposed at a position orthogonal to the radiation delivery device 20 relative to the target position. Specifically, for example, the imaging module 40 and the radiation delivery device 20 are located in two perpendicular directions of the target position.

[0055] The present application also provides a radiation delivery method, comprising: using a radiation delivery device 20 that can be movably accommodated in a shielding cabin 10 to deliver treatment radiation to a target position in a treatment chamber 101 located in the shielding cabin 10, and the shielding cabin 10 can shield radiation.

[0056] In addition, the present application also provides a computer-readable storage medium having instructions stored thereon, which, when executed by a processor, implement the following steps: positioning an object 200 at a target position in a treatment chamber 101 within a shielding cabin 10, wherein the shielding cabin 10 is capable of shielding radiation; and utilizing a radiation delivery device 20 that can be movably housed within the shielding cabin 10 to deliver treatment radiation to the object 200.

[0057] Those skilled in the art can understand that all or part of the processes in the above-mentioned embodiment methods can be completed by instructing the relevant hardware through a computer program, and the computer program can be stored in a non-volatile computer-readable storage medium. When the computer program is executed, it can include the processes of the embodiments of the above-mentioned methods.

The database involved in each embodiment provided in this application may include at least one of a relational database and a non-relational database.

[0058] In summary, the radiotherapy device 100 of the present invention uses the shielding cabin 10 to shield the radiation delivery device 20, so that it is possible to avoid the entire room where the radiotherapy device 100 is placed being shielded, which has the effect of reducing costs. In addition, the position of the radiation delivery device 20 in the shielding cabin 10 relative to the shielding cabin 10 is adjusted to achieve the treatment radiation entering the target position at different angles. In this way, on the one hand, it is possible to reduce the volume required to meet the multi-angle irradiation treatment radiation and reduce costs, and on the other hand, it is possible to make the distance between the radiation delivery device 20 and the target position smaller, which has the effect of further improving the treatment effect of the radiotherapy device 100 during radiotherapy.
