Description

Technical Field

[0001] This application relates to the field of accelerator technology, and in particular to a beam multi-angle delivery system. Background Technology

[0002] Particle beam therapy, as an advanced cancer treatment method, has been widely used and developed in the medical field. By precisely irradiating tumor cells with high-energy particle beams, damage to normal tissues can be effectively reduced, improving treatment outcomes. However, a complex delivery system is required to ensure that the particle beam is accurately delivered to the patient at different angles.

[0003] In existing technologies, the original beam is a single transport line, and this transport line has treatment rooms with fixed angles and multi-angle treatment rooms with rotating heads. For rooms with fixed gantry angles, it is only possible to treat a single type of tumor and it is not possible to quickly and flexibly deliver beams at different angles. Therefore, it is necessary to design a transport system that can achieve multi-angle delivery. Utility Model Content

[0004] To address the issue of single-angle tumor treatment being unable to achieve flexible, multi-angle treatment, this application provides a beam multi-angle delivery system.

[0005] The beam multi-angle delivery system provided in this application adopts the following technical solution:

[0006] A multi-angle beam delivery system includes a particle vacuum pipeline, a particle beam generating device, a treatment chamber, and a deflection mechanism; the output end of the particle beam generating device is connected to the particle vacuum pipeline, the deflection mechanism is installed on the particle vacuum pipeline, the treatment chamber and the particle vacuum pipeline form at least three transmission paths, and the beams transmitted by the at least three transmission paths and the particle vacuum pipeline form different angles.

[0007] By adopting the above technical solution, the particle generating device is used to generate a particle beam. After the particle beam is accelerated by the accelerator, it is transmitted along the particle vacuum pipe and then transmitted through the fixed gantry in the treatment room. There are at least three transmission paths and different angles of beam transmission for treatment, which facilitates the treatment of tumors in different parts of the patient on the fixed gantry and the treatment effect at different angles.

[0008] Optionally, the transmission path includes a first transmission path, a second transmission path, and a third transmission path, wherein the first transmission path and the particle vacuum pipe form an acute angle, the second transmission path and the particle vacuum pipe form a right angle, and the third transmission path and the particle vacuum pipe form an obtuse angle.

[0009] By adopting the above technical solutions, the first transmission path and the particle vacuum pipe form an acute angle, allowing the particle beam to be flexibly adjusted within a small angle range, which is suitable for treatment areas requiring precise control; the second transmission path and the particle vacuum pipe form a right angle, allowing the particle beam to enter the treatment chamber directly and vertically, improving the linear transmission efficiency of the beam and reducing energy loss; the third transmission path and the particle vacuum pipe form an obtuse angle, allowing the particle beam to be delivered within a larger angle range, which is suitable for treatment needs requiring large-area coverage, meeting the needs of various treatment scenarios and improving the system's flexibility and applicability.

[0010] Optionally, the deflection mechanism includes a first deflection magnet, a second deflection magnet, and a third deflection magnet, which are arranged sequentially along the beam transmission direction of the particle vacuum pipe.

[0011] By adopting the above technical solutions, the multi-angle beam delivery system can achieve precise transmission of particle beams at multiple different angles, effectively control the direction changes of the beam, and ensure that the beam can be flexibly switched between different paths, thereby meeting the needs of different treatment positions, improving the flexibility and adaptability of the system, reducing errors caused by path changes, and improving treatment accuracy.

[0012] Optionally, the first deflecting magnet is one or more deflecting magnets.

[0013] By adopting the above technical solution, the first deflecting magnet can select one or more deflecting magnets as needed, thereby flexibly adjusting the deflection angle and range of the beam and improving the flexibility of the system.

[0014] Optionally, the direction of the accelerated beam output from the particle vacuum pipe and the direction of the beam output from the particle beam generating device are perpendicular to each other.

[0015] By adopting the above technical solutions, the transmission efficiency and accuracy of the beam are improved, and scattering and energy loss caused by inconsistent beam direction are reduced, thereby improving the treatment effect and patient safety.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By setting up a particle vacuum pipeline, a particle beam generating device, a treatment chamber, and a deflection mechanism, the particle beam can be transmitted along at least three different transmission paths, thereby achieving multi-angle beam delivery and improving the flexibility and accuracy of treatment.

[0018] 2. The first, second, and third transmission paths form acute, right, and obtuse angles with the particle vacuum channel, respectively, allowing the particle beam to cover a wider treatment area, adapting to tumors of different locations and shapes, and enhancing the applicability of the treatment.

[0023] The following is in conjunction with the appendix Figure 1 To be continued Figure 2 This application will be described in further detail.

[0024] This application discloses a beam multi-angle delivery system.

[0025] Reference Figure 1 A multi-angle beam delivery system includes a particle vacuum pipeline 1, a particle beam generating device 2, a treatment chamber 3, and a deflection mechanism 6. The particle vacuum pipeline 1 consists of multiple segmented pipelines. The output end of the particle beam generating device 2 is connected to the particle vacuum pipeline 1. The particle beam generating device 2 is a cyclotron accelerator 4 used to generate high-energy particle beams. The deflection mechanism 6 is installed on the particle vacuum pipeline 1. The treatment chamber 3 and the particle vacuum pipeline 1 form at least three transmission paths. The at least three transmission paths and the beam transmitted by the particle vacuum pipeline 1 form different angles to realize tumor treatment at different angles, which facilitates rapid, flexible, and multi-angle transmission treatment.

[0026] The deflection mechanism 6 includes a first deflection magnet 61, a second deflection magnet 62, and a third deflection magnet 63. The first deflection magnet 61, the second deflection magnet 62, and the third deflection magnet 63 are arranged sequentially along the beam transmission direction of the particle vacuum pipe 1. The deflection magnets are controlled by electromagnetic coils to achieve dynamic adjustment.

[0027] The transmission path is divided into a first transmission path 51, a second transmission path 52, and a third transmission path 53. The first transmission path 51 forms an acute angle with the particle vacuum pipe 1, the second transmission path 52 forms a right angle with the particle vacuum pipe 1, and the third transmission path 53 forms an obtuse angle with the particle vacuum pipe 1. The particle beam transmission therapy at different angles provides a wider treatment coverage for tumors and improves the flexibility of treatment.

[0028] See Figure 1 and Figure 2 As shown, the first deflecting magnet 61 is one or more deflecting magnets, which can be flexibly configured according to actual needs. When a larger deflection angle is required, the number of deflecting magnets can be increased. Each deflecting magnet is made of high-strength permanent magnet material and has a stable magnetic field strength, which can adapt to different treatment environments.

[0029] The direction of the accelerated beam output from particle vacuum pipe 1 is perpendicular to the direction of the beam output from particle beam generating device, which effectively improves the transmission efficiency and accuracy of the beam, reduces energy loss caused by inconsistent beam direction, and improves the treatment effect and safety.

[0030] The implementation principle of the beam multi-angle delivery system in this application embodiment is as follows: by setting multiple deflection mechanisms 6 on the particle vacuum pipe 1, the particle beam is transmitted along at least three different transmission paths. Since the patient lies on the fixed frame, multiple different angles are formed by the different transmission paths and the particle vacuum pipe 1, thereby achieving different therapeutic effects on the tumor from different angles and improving the flexibility and accuracy of treatment. The first transmission path 51, the second transmission path 52 and the third transmission path 53 respectively form different range angle treatment areas with the particle vacuum pipe 1, which are suitable for treating tumors of different locations and shapes.
