Description

Technical Field

[0001] This invention relates to the field of medical radiation technology, specifically to a multi-angle flash irradiation device and method. Background Technology

[0002] Most existing multi-treatment-head accelerator tubes employ integrated systems. The core components of these systems include an excitation source, an electron gun, and an accelerator tube, which together form a complete beam output device. Each treatment head is equipped with an independent microwave excitation source, electron gun, and electron accelerator tube, among other key equipment. The components are paired one-to-one with the treatment head to achieve simultaneous radiotherapy for different patients or multiple sites on the same patient. While this design significantly improves the convenience and efficiency of clinical operations, it also has some significant drawbacks: 1. High Cost: Each additional treatment head requires a complete set of acceleration components, directly leading to a significant increase in equipment costs and subsequent maintenance expenses. For medical institutions, this not only increases the initial investment burden but also creates a financial burden for long-term operation.

[0003] 2. Large space requirement: Because each treatment head requires individual hardware installation, the entire system is relatively large and has high space requirements. Especially in limited medical environments, it may be difficult to find enough space to accommodate such a large cluster of devices.

[0004] 3. Complexity and Failure Rate: More components mean a more complex system architecture, which increases the probability of failure. A problem with even one critical component can lead to the downtime of the entire system, severely impacting the provision of normal medical services. Furthermore, highly complex systems require technicians with a higher level of expertise and technical skills to ensure stable equipment operation.

[0005] 4. For example, in the prior art, Maisheng Medical disclosed a particle therapy system with a ring gantry design in patent CN117836034A, which can achieve 360° omnidirectional beam output. However, in order to achieve 360° omnidirectional beam output, the system is designed with a complex ring gantry and beam transmission system. At the same time, in order to ensure sufficient treatment space or installation space for imaging devices, the entire device is large and heavy.

[0006] Therefore, existing technologies need further development. Summary of the Invention

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] According to Embodiment 1 of the present invention, a multi-angle Flash irradiation device is provided. Please refer to [link / reference]. Figures 1 to 3 The device includes: a beam generating component for emitting an electron beam; a beam deflection component for deflecting the electron beam, the beam deflection component being connected to the beam generating component and having a radiotherapy space; and multiple treatment heads 11, each connected to the beam deflection component, the multiple treatment heads 11 being independently positioned within the radiotherapy space, and the positions and orientations of the multiple treatment heads 11 being different, the multiple treatment heads 11 being used to perform radiotherapy on the tumor from different directions.

[0030] By adopting the above technical solution and designing multiple treatment heads 11, after the beam generating component emits an electron beam, the electron beam is deflected by the beam deflection component. When it is necessary to emit a beam to the target area, since the positions and orientations of the multiple treatment heads 11 are different, the current magnitude of the beam deflection component connected to each treatment head 11 is selected according to the position of the different treatment heads 11 to ensure that the beam is switched to the correct treatment head 11 for dose delivery. The entire process does not require the gantry to rotate; only the sequence and switching of each timing step need to be controlled to achieve 360° beam emission. The equipment has low wear, high control precision, long service life, and convenient control, thus solving the technical problem of large size and heavy weight of the entire equipment caused by the one-to-one pairing of assembly components and machine heads in related technologies.

[0031] Among them, the switch trigger signal (periodic) arrives at the excitation source 1, and the excitation source 1 generates a corresponding microwave signal based on the waveform of the trigger signal.

[0032] Please refer to Figure 1 The beam deflection component includes: a first beam deflection assembly, which is connected to a plurality of treatment heads 11; the electron beam is deflected by the first beam deflection assembly and then emitted through the treatment head 11; and a second beam deflection assembly, which is connected to the treatment head 11; the electron beam is deflected by the second beam deflection assembly and then emitted through the treatment head 11.

[0033] By adopting the above technical solution, and through the design of the first beam deflection component and the second beam deflection component, it is only necessary to adjust the current of the first beam deflection component and the second beam deflection component to the appropriate level. After the high-energy electron beam is deflected by the first beam deflection component or the second beam deflection component, it is emitted by the corresponding treatment head 11. The overall structure is simple and easy to control.

[0034] The treatment head can directly emit electrons, or it can have a tungsten target or a rotating tungsten target. The treatment head can also emit X-rays, or even ultra-high dose rate X-rays.

[0035] Please refer to Figure 1 The first beam deflection assembly includes: a first scanning magnet 9, the input end of which is connected to the output end of the beam deflection assembly, and the first scanning magnet 9 is used to deflect the electron beam; a first deflection magnet 10, which is connected to the output end of the first scanning magnet 9, and a plurality of treatment heads 11 are spaced apart on the side of the first deflection magnet 10 away from the first deflection magnet 10, and the output end of the first deflection magnet 10 is connected to the treatment heads 11 respectively; the first deflection magnet 10 is used to deflect the electron beam output by the first scanning magnet 9, so that the electron beam deflected by the first deflection magnet 10 enters the corresponding treatment head 11 among the treatment heads 11.

[0036] By adopting the above technical solution, through the design of the first scanning magnet 9 and the first deflection magnet 10, during the process of the electron beam entering the corresponding treatment head 11, the first scanning magnet 9 controls the deflection angle of the electron beam in the XY plane, so that the electron beam moves at different deflection angles. The first deflection magnet 10 deflects the electron beams at different deflection angles, so that these electron beams all point to the same target area, that is, these electron beams all coincide with the axis of the corresponding treatment head in part of the treatment head 11, and all point to the same target area, that is, the target tumor.

[0037] Please refer to Figure 1 The second beam deflection assembly includes: a second scanning magnet 12, the input end of which is connected to the output end of the beam processing assembly, and the second scanning magnet 12 is used to deflect the electron beam; a second deflecting magnet 13, which is disposed opposite to the side of the first deflecting magnet 10 away from the first scanning magnet 9, the first deflecting magnet 10 and the second deflecting magnet 13 forming a radiotherapy space, the second deflecting magnet 13 being connected to the output end of the second scanning magnet 12, and the remaining treatment heads 11 of a plurality of treatment heads 11 are disposed at intervals on the side of the second deflecting magnet 13 away from the second scanning magnet 12, the output end of the second deflecting magnet 13 being connected to the remaining treatment heads 11 respectively; the second deflecting magnet 13 is used to deflect the electron beam output by the second scanning magnet 12, so that the electron beam deflected by the second deflecting magnet 13 enters the corresponding treatment head of the remaining treatment heads 11.

[0038] By adopting the above technical solution, through the design of the second scanning magnet 12 and the second deflection magnet 13, during the process of the electron beam entering the corresponding treatment head 11, the first scanning magnet 9 controls the electron beam in the XY plane, and the second scanning magnet 12 controls the deflection angle of the electron beam, so that the electron beam moves at different deflection angles. The second deflection magnet 13 deflects the electron beams at different deflection angles, so that these electron beams all point to the same target area. That is, these electron beams all coincide with the axis of the corresponding treatment head 11 in the other treatment heads 11, and all point to the same target area, that is, the target tumor.

[0039] Please refer to Figure 1 The beam generation component includes: an excitation source 1, which provides a low-energy microwave signal; a signal transmission component connected to the excitation source 1, which transmits the low-energy microwave signal; and a signal processing component connected to the output of the signal transmission component, which processes the low-energy microwave signal into a high-energy microwave signal and, based on the high-energy microwave signal, selectively outputs it to the first beam deflection component or the second beam deflection component; the output of the signal processing component is connected to the beam deflection component.

[0040] By adopting the above technical solution, through the design of the signal transmission component and the signal processing component, a pulsed microwave transmission is achieved by propagating a trigger signal to the excitation source 1. The low-energy microwave signal is transmitted to the signal processing component through the signal transmission component, and the low-energy microwave signal is processed into a high-energy microwave signal through the signal processing component. The high-energy microwave signal is selectively output to the first beam deflection component or the second beam deflection component. After the high-energy electron beam is deflected by the beam deflection component, it is controllably emitted from multiple treatment heads 11 for radiotherapy of tumors from different directions.

[0041] Please refer to Figure 1 The signal transmission component includes: a first transmission line connected to the first output terminal of the excitation source 1, the first transmission line being used to transmit low-energy microwave signals; a second transmission line connected to the second output terminal of the excitation source 1, the second transmission line being used to transmit low-energy microwave signals; the signal phase of the second transmission line being opposite to the signal phase of the first transmission line; and an inverter 21 disposed on the first transmission line or the second transmission line, the inverter 21 being used to invert the low-energy microwave signals on the transmission line in which it is located.

[0042] By adopting the above technical solution and through the design of inverter 21, during the transmission of low-energy microwave signals, inverter 21 inverts the low-energy microwave signals on the transmission line so that the beam deflection component can determine the working state.

[0043] Please refer to Figure 1 The signal processing component includes: a first klystron 4, connected to the output terminal of the first transmission line 2, for amplifying the low-energy microwave signal transmitted by the first transmission line 2; a second klystron 5, connected to the output terminal of the second transmission line 3, for amplifying the low-energy microwave signal transmitted by the second transmission line 3; a coupler 6, with the output terminals of both the first klystron 4 and the second klystron 5 connected to the coupler 6, for combining the high-energy microwave signal output by the first klystron 4 and the high-energy microwave signal output by the second klystron 5; a first accelerator tube 7, connected to the first output terminal of the coupler 6, for receiving the high-energy microwave signal output by the coupler 6; and a second accelerator tube 8, connected to the second output terminal of the coupler 6, for receiving the high-energy microwave signal output by the coupler 6. The output terminals of the first accelerator tube 7 and the second accelerator tube 8 form the output terminals of the signal processing component.

[0044] By adopting the above technical solution, through the design of coupler 6, first accelerating tube 7, and second accelerating tube 8, during the process of accelerating the low-energy electron beam to a high-energy electron beam, coupler 6 selects to transmit the high-energy microwave signal to the first accelerating tube 7 or the second accelerating tube 8 based on the output direction of the synthesized high-energy microwave signal; when the output direction of the synthesized high-energy microwave signal is determined to be a positive phase signal, coupler 6 transmits the high-energy microwave signal to the first accelerating tube 7; when the output direction of the synthesized high-energy microwave signal is determined to be an inverted phase signal, coupler 6 transmits the high-energy microwave signal to the second accelerating tube 8.

[0045] Coupler 6 is a 3dB coupler, which can be replaced by a power divider.

[0046] Please refer to Figure 1The signal processing component further includes: a first electron gun, disposed on the side of the first klystron 4 away from the second klystron 4, for emitting a low-energy electron beam at the first klystron 4 to process the low-energy microwave signal and form a high-energy microwave signal; a second electron gun, disposed on the side of the second klystron 5 away from the first klystron 4, for emitting a low-energy electron beam at the second klystron 5 to process the low-energy microwave signal and form a high-energy microwave signal; a third electron gun, disposed on the side of the first accelerator tube 7 away from the second accelerator tube 8, for emitting a low-energy electron beam at the first accelerator tube 7; the low-energy electron beam forms a high-energy electron beam within the first accelerator tube 7 through the high-energy microwave signal; and a fourth electron gun, disposed on the side of the second accelerator tube 8 away from the first accelerator tube 7, for emitting a low-energy electron beam at the second accelerator tube 8; the low-energy electron beam forms a high-energy electron beam within the second accelerator tube 8 through the high-energy microwave signal.

[0047] By adopting the above technical solution, the first electron gun is used to emit a low-energy electron beam to the first klystron 4, so that the first klystron 4 processes the low-energy microwave signal; the second electron gun is used to emit a low-energy electron beam to the second klystron 5, so that the second klystron processes the low-energy microwave signal to form a high-energy microwave signal; the third electron gun is used to emit a low-energy electron beam to the first accelerating tube 7; the low-energy electron beam is formed into a high-energy electron beam within the first accelerating tube 7 by passing through the high-energy microwave signal; the fourth electron gun is used to emit a low-energy electron beam to the second accelerating tube 8; the low-energy electron beam is formed into a high-energy electron beam within the second accelerating tube 8 by passing through the high-energy microwave signal.

[0048] In this process, a trigger signal is transmitted to the excitation source 1 to achieve pulsed microwave transmission. The single-sided inverter 21 adjusts the phase of the microwave pulse in the first klystron 4 or the second klystron 5. The microwave signal in the first accelerator tube 7 or the second accelerator tube 8 is distributed and synthesized by a 3dB coupler. The 3dB coupler is based on the energy distribution plan and the multimode interference effect and is implemented through an internal coupling structure. The electron beam emitted by the third electron gun or the fourth electron gun and the microwave emitted by the 3dB coupler enter the first accelerator tube 7 or the second accelerator tube 8 to achieve electron acceleration. The XY plane distribution angle of the electron beam is controlled by the first scanning magnet 9 or the second scanning magnet 12. The direction of the electron beam is adjusted by the first deflection magnet 10 or the second deflection magnet 13, ultimately achieving the situation where multiple treatment heads 11 can controllably emit beams separately.

[0049] Please refer to Figure 1 The multi-angle Flash irradiation device also includes a treatment planning module, which is connected to at least a portion of the beam generating component and the beam deflection component, respectively. The treatment planning module is used to plan the path for delivering the dose to the tumor tissue.

[0050] By adopting the above technical solution and through the design of the treatment planning module, when radiotherapy is required on tumor tissue, the treatment planning module plans the path for delivering the dose to the tumor tissue. The position of the treatment head is adjusted in advance according to the dose delivery angle planned by the treatment planning module, and the spatial position of the treatment head is not adjusted during the dose delivery process, thereby improving the flexibility of the equipment.

The first transmission line 2 and the second transmission line 3 can be microwave transmission lines composed of various waveguides.

[0059] An inverter 21 is also provided on the first transmission line 2 or the second transmission line 3, which can invert the low-energy microwave signal of one of the channels. In this embodiment, the inverter 21 is provided on the first transmission line 2.

[0060] Specifically, when inverter 21 is working, it inverts the low-energy microwave signal on the first transmission line 2, so the low-energy microwave signal received by the first klystron 4 and the amplified microwave signal are inverted signals.

[0061] The two low-energy microwave signals are amplified into high-energy microwave signals by the first klystron 4 and the second klystron 5, and then injected into the coupler 6 to synthesize and determine the output direction.

[0062] The distances from coupler 6 to the first accelerating tube 7 and the second accelerating tube 8 differ by an odd multiple of λ / 2.

[0063] In this embodiment, if the high-energy microwave signals output by the first klystron 4 and the second klystron 5 are in phase, the coupler 6 combines the two high-energy microwave signals and injects them into the first accelerating tube 7, thereby accelerating the low-energy electron beam to a high-energy electron beam; if the high-energy microwave signals output by the first klystron 4 and the second klystron 5 are in phase, the coupler 6 combines the two high-energy microwave signals and injects them into the second accelerating tube 8, thereby accelerating the low-energy electron beam to a high-energy electron beam.

[0064] After the high-energy microwave signal is synthesized, it is injected into only one of the accelerating tubes, meaning that at any given time, only one of the two accelerating tubes is working.

[0065] The first acceleration tube 7 and the second acceleration tube 8 each have multiple treatment heads 11.

[0066] These treatment heads 11 are all directed at the target area, namely the tumor tissue.

[0067] They can be evenly or unevenly distributed in the same plane, or of course, they can be arranged in different planes.

[0068] If they are not on the same plane, the treatment head corresponding to the first acceleration tube 7 can be placed in a plane A, and the treatment head corresponding to the second acceleration tube 8 can be placed in another plane B. Planes A and B can have a certain translation distance, or they can have a certain angle around the target area, or they can have both translation distance and a certain angle.

[0069] In practical applications, the preferred arrangement should be that plane A and plane B are coplanar or that the two planes have a certain angle around the target area.

[0070] When planes A and B are arranged at a certain angle, their corresponding scanning magnets and deflecting magnets should rotate by the corresponding angle.

[0071] In this embodiment, 10 treatment heads 11 are provided and arranged in a coplanar manner.

[0072] The first acceleration tube 7 is connected to five of the treatment heads 11, and the second acceleration tube 8 is connected to the other five treatment heads 11.

[0073] Because the treatment head 11 is in a different spatial position, a beam deflection component must be installed between the acceleration tube and the treatment head 11. The beam deflection component mainly includes a scanning magnet and a deflection magnet.

[0074] This embodiment is described from the perspective of the first accelerator tube 7.

[0075] The first scanning magnet 9, the first deflecting magnet 10, and the treatment head 11 are sequentially connected to the first accelerating tube 7, causing the electron beam to be deflected twice and finally emitted through one of the treatment heads 11.

[0076] The first scanning magnet 9 is mainly used to deflect the electron beam at a small angle, while the first deflecting magnet 10 is mainly used for deflection at a large angle.

[0077] Similar to the first acceleration tube 7, the second acceleration tube 8 also needs to be equipped with a second scanning magnet 12 and a second deflection magnet 13 to control the direction of the electron beam and select the emission treatment head 11.

[0078] The working principle of beam deflection is as follows: Figure 2 As shown: Taking the example electron beam 20 emitted from the first accelerating tube 7 as an example, the example electron beam 20 is deflected once after being adjusted by the first scanning magnet 9 of length L1. After drifting a certain distance, the example electron beam 20 reaches the first deflecting magnet 10 and is deflected a second time. Finally, the electron beam is emitted onto the tumor tissue through the treatment head 11.

[0079] The specific deflection depends on the magnitude of the magnet's magnetic field and the geometric positions of the scanning magnet and the deflecting magnet.

[0080] In this embodiment, the first acceleration tube 7 corresponds to the five treatment heads 11 on the left side, and the first scanning magnet 9 is equipped with five current levels. The electron beam is deflected in five different directions by controlling the electric and magnetic fields of the scanning magnet through the current.

[0081] Of course, if one of the treatment heads 11 is arranged horizontally, the electrons in the first accelerating tube 7 can reach the horizontally arranged treatment head 11 without deflection. At this time, the first scanning magnet 9 can also be set with four current levels.

[0082] After being deflected and drifted by the first scanning magnet 9, the electron beam finally enters the first deflecting magnet 10. After receiving the electron beam deflected out by the first scanning magnet 9, the first deflecting magnet 10 also deflects the electron beam at a large angle a second time by adjusting the current intensity of the first deflecting magnet 10 itself, and finally reaches the position of the set beam output treatment head 11.

[0083] Because the larger the deflection angle, the higher the requirements for electron loss and precise control of the electron beam, in order to reduce the complexity of control, fewer treatment heads 11 can be set. Therefore, in this patent embodiment, the first deflection magnet 10 and the second deflection magnet 13 correspond to 5 treatment heads 11 respectively.

[0084] Generally, the five current levels of the first scanning magnet 9, the current on the first deflecting magnet 10, and the position of the treatment head 11 are corresponding.

[0085] When the position of the treatment head 11 changes, the movement path of the electron beam needs to be replanned, which means adjusting the current on the first scanning magnet 9 and the first deflection magnet 10, as well as the geometric relationship between the first scanning magnet 9 and the first deflection magnet 10.

[0086] Of course, the treatment head 11 can directly emit an electron beam, or the treatment head 11 can be equipped with a tungsten target, especially a rotating tungsten target, so that the treatment head 11 can also emit X-rays, or even ultra-high dose rate X-rays.

[0087] In practical use, in order to meet the requirements of intelligent equipment, the X-ray FLASH multi-angle irradiation device also includes a treatment planning module. The treatment planning module is used to plan the path for delivering the dose to the tumor tissue. The treatment planning module is connected to the inverter 21 and the first scanning magnet 9.

[0088] The working process is illustrated below: In this embodiment, a total of 10 treatment heads 11 are arranged, namely the first treatment head 110, the second treatment head 111, the third treatment head 112, the fourth treatment head 113, the fifth treatment head 114, the sixth treatment head 115, the seventh treatment head 116, the eighth treatment head 117, the ninth treatment head 118, and the tenth treatment head 119. The first treatment head 110 to the fifth treatment head 114 are associated with the first acceleration tube 7, and the sixth treatment head 115 to the tenth treatment head 119 are associated with the second acceleration tube 8.

[0089] For example, a tumor tissue needs to be dosed from three directions: the second treatment head 111, the sixth treatment head 115, and the ninth treatment head 118, and the order of dose delivery is the second treatment head 111, the ninth treatment head 118, and the sixth treatment head 115.

[0090] Steps: Inverter 21, scanning magnet, deflecting magnet to obtain the dosage delivery sequence planned by the treatment plan module, and determine the working status.

[0091] Based on the order of dosage delivery: second treatment head 111, ninth treatment head 118, and sixth treatment head 115, there are three working sequences: sequence I, sequence II, and sequence III.

[0092] Timing I corresponds to the second treatment head 111, timing II corresponds to the ninth treatment head 118, and timing III corresponds to the sixth treatment head 115.

[0093] According to the acceleration tube corresponding to the treatment head 11, during timing I, the first acceleration tube 7, the first scanning magnet 9, and the first deflection magnet 10 should all be working, the inverter 21 should not be turned on, and the low-energy microwave signal of the excitation source 1 should not be inverted.

[0094] During timing II and timing III, the second accelerating tube 8, the second scanning magnet 12, the second deflecting magnet 13, and the inverter 21 are operational.

[0095] The process is as follows: In timing I, according to the dosage planned by the treatment planning module, the treatment head 11 is the second treatment head 111. The first accelerator tube 7, the first scanning magnet 9, and the first deflection magnet 10 should all be working, while the inverter 21 is not working. The positive-phase low-energy microwave signal generated by the excitation source 1 is simultaneously transmitted from the first transmission line 2 and the second transmission line 3 to the first klystron 4 and the second klystron 5, respectively. The two low-energy microwave signals are amplified into high-energy microwave signals by the first klystron 4 and the second klystron 5, and then injected into the coupler 6. In this embodiment, the coupler 6 is a 3D coupler. The coupler 6 determines whether the two high-energy microwave signals are in phase before injecting the combined microwave signal into the first accelerator tube. 7 or the second accelerating tube 8; because the inverter 21 is not working in timing I, the two high-energy microwave signals are in phase, so the synthesized microwave signal is injected into the first accelerating tube 7, and the synthesized high-energy microwave signal establishes a high-frequency electric field in the first accelerating tube 7; the low-energy electron beam in the first accelerating tube 7 is gradually accelerated into a high-energy electron beam under the action of the high-frequency electric field; the current of the first scanning magnet 9 and the first deflecting magnet 10 is adjusted to the appropriate level, and the high-energy electron beam is deflected once by the first scanning magnet 9 and twice by the first deflecting magnet 10, and then emitted from the second treatment head 111; if there is a tungsten target in the second treatment head 111, the high-energy electron beam is converted into an X-ray beam and emitted to the tumor target area, completing the first dose delivery.

[0096] In sequence II, according to the dosage delivery plan of the treatment planning module, treatment head 11 is the ninth treatment head 118. The second accelerating tube 8, the second scanning magnet 12, the second deflecting magnet 13, and the inverter 21 should all be operational. Because the inverter 21 is operational, the positive-phase low-energy microwave signal generated by the excitation source 1 becomes an inverted low-energy microwave signal in the first transmission line 2, while it remains a positive-phase low-energy microwave signal in the second transmission line 3. The inverted low-energy microwave signal and the positive-phase low-energy microwave signal are transmitted to the first klystron 4 and the second klystron 5, respectively, and then amplified into an inverted high-energy microwave signal and a positive-phase high-energy microwave signal, respectively. After the two high-energy microwave signals are injected into the coupler 6 for synthesis and distribution, since the two high-energy microwave signals are out of phase, the microwave signal synthesized by the coupler 6 is injected into the second accelerating tube 8. The synthesized high-energy microwave signal establishes a high-frequency electric field in the second accelerating tube 8. Under the action of the high-frequency electric field, the low-energy electron beam in the second accelerating tube 8 is gradually accelerated into a high-energy electron beam. The current of the second scanning magnet 12 and the second deflecting magnet 13 is adjusted to a suitable level. After the high-energy electron beam is deflected once by the second scanning magnet 12 and twice by the second deflecting magnet 13, it is emitted from the ninth treatment head 118. If there is a tungsten target in the ninth treatment head 118, the high-energy electron beam is converted into an X-ray beam and emitted to the tumor target area to complete the first dose delivery; the timing III is similar to the timing II, the difference is that the treatment head 11 that emits the beam is different, so the current level in the second scanning magnet 12 and the second deflecting magnet 13 is different from the level in timing II.

[0097] If there are more dosage delivery options, simply add or switch delivery sequences and ensure proper timing control.

[0098] This invention utilizes an inverter 21 and a coupler 6, along with a first klystron 4, a second klystron 5, a first accelerator tube 7, a second accelerator tube 8, a first scanning magnet 9, a first deflecting magnet 10, a second scanning magnet 12, a second deflecting magnet 13, and multiple treatment heads 11. Based on the delivery plan, the inverter 21 is selected to correspond to the accelerator tube of each treatment head 11 in multiple dose delivery sequences. The current magnitude of the connected scanning magnet and deflecting magnet is adjusted according to the position of the treatment head 11 to ensure the beam switches to the correct treatment head 11 for dose delivery. The entire process requires no gantry rotation; precise and rapid control of the sequence and switching of each timing sequence is all that is needed to achieve 360° beam output. The equipment experiences minimal wear, high control precision, long service life, and convenient control, making it particularly suitable for Flash radiotherapy.

[0099] Of course, to improve the flexibility of the device, the entire treatment head 11 can be designed to be rotatable and adjustable.

[0100] The position of the treatment head 11 is adjusted in advance according to the dose delivery angle planned by the treatment plan module. The spatial position of the treatment head 11 is not adjusted during the dose delivery process. The working timing of the inverter 21 and the working current in each timing sequence of the scanning magnet and the deflection magnet are selected according to the position of the treatment head 11.

[0101] To improve work efficiency and stability, the entire device also includes an imaging module 14, which can be a CT system or other imaging system. The patient lies on the treatment bed 15 and the imaging module 14 performs imaging scans on the patient. The treatment planning module acquires the scan images, plans the dose delivery sequence and other beam parameters, and then delivers the dose in situ. The entire diagnosis and treatment process is very short and always delivers the dose based on the latest tumor location and morphology, with high precision.
