Description

Technical Field

[0001] The present invention belongs to the technical field of accelerators, and in particular relates to a method, device, equipment and storage medium for adjusting output energy of an accelerator. Background Art

[0002] The usual method of tumor radiotherapy is to use the high-energy radiation beam generated by a linear accelerator to accurately hit the tumor target area that needs to be irradiated, thereby killing tumor cells while protecting the surrounding critical organs from damage by radiation.

[0003] The principle of linear accelerator to generate high-energy rays is to use the microwaves generated by magnetron or klystron to accelerate the electron beam generated by the electron gun to a speed close to the speed of light in the resonant cavity of the accelerator tube, thereby obtaining electron beam rays with sufficient energy. The high-energy electron beam can be used directly for radiotherapy or converted into X-rays for radiotherapy. In order to adapt to patients of different sizes or treatment areas, the linear accelerator can output rays of different energies as needed to achieve better treatment effects.

[0004] The output of multiple energy rays by existing linear accelerators is usually achieved by adjusting the energy switch on the accelerating tube. The principle is to select a coupling cavity in the standing wave accelerating tube, set an adjusting device in it, and change the working state of the coupling cavity by adjusting the position of the device in the coupling cavity, so as to adjust the axial field distribution of the accelerating cavity behind the coupling cavity, thereby achieving the purpose of adjusting the output energy of the accelerated beam. In addition, conventional linear accelerators often use C-arm or O-arm structures for rotational therapy of rays, and then add a treatment bed that can position the patient to form the entire linear accelerator system.

[0005] The energy regulation method of existing linear accelerators can usually only achieve two fixed energy outputs, and cannot achieve multiple energy outputs. At the same time, an accelerating tube with an energy switch is required to achieve this, which greatly increases the difficulty of producing and manufacturing the accelerating tube. In addition, the introduction of a moving structure will also have a certain impact on the service life of the accelerating tube.

[0006] The motion system of the current linear accelerator system usually adopts a conventional treatment bed, which can only perform simple linear motion, with a control accuracy of only about 1 mm and a very limited range of motion. It is difficult to meet the needs of new radiotherapy technology for precise positioning and multi-target treatment. Summary of the invention

[0007] In order to solve the above technical problems, the present invention proposes a method, device, equipment and storage medium for adjusting the output energy of an accelerator.

[0008] In order to achieve the above object, the technical solution of the present invention is as follows:

[0009] In the first aspect, the present invention discloses a method for adjusting the output energy of an accelerator, by adjusting one or more of the current of an electron gun, the width and amplitude of a pulse current output by a magnetron modulator, the current of a magnetron magnet, and the phase relationship between an electron beam pulse emitted by the electron gun and a microwave pulse of the magnetron, thereby changing the radiation energy and dose rate output by the accelerator to meet the requirements.

[0010] Based on the above technical solution, the following improvements can be made:

[0011] As a preferred solution, when the width and amplitude of the pulse current output by the magnetron modulator, the current of the magnetron magnet, and the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron are fixed,

[0012] That is, under the condition of certain microwave input power, the acceleration energy decreases with the increase of beam load. The greater the current of the electron gun, the smaller the ray energy output by the accelerator.

[0013] Conversely, the greater the accelerator's output radiation energy.

[0014] As a preferred solution, when the current of the electron gun and the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron remain unchanged,

[0015] The larger the width and amplitude of the pulse current output by the magnetron modulator, the greater the energy of the ray output by the accelerator.

[0016] On the contrary, the accelerator outputs smaller radiation energy.

[0017] As a preferred solution, when the width and amplitude of the pulse current output by the magnetron modulator are adjusted, the current of the magnetron electromagnet is synchronously adjusted to match the input power of the magnetron, so that the magnetron can stably generate microwaves.

[0018] As a preferred solution, when the current of the electron gun, the width and amplitude of the pulse current output by the magnetron modulator, and the current of the magnetron magnet are fixed,

[0019] When the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron are completely synchronized, the accelerator outputs the maximum radiation energy.

[0020] When there is an advance or lag between the two pulses, the energy of the accelerator output radiation will decrease accordingly.

[0021] As a preferred solution, the electron beam pulses emitted by the electron gun and the microwave pulses of the magnetron are synchronized, and when the pulse width is fixed, the frequency of either pulse can be adjusted, that is, the radiation dose rate can be adjusted while maintaining the stability of the accelerator output radiation energy.

[0022] As a preferred solution, it specifically includes:

[0026] Step S3: Repeat step S2 to obtain the adjustment parameters corresponding to each candidate energy output value, and record them in the parameter adjustment-candidate energy table;

[0027] Step S4: In clinical application, according to any selected candidate energy output dose, the corresponding adjustment parameter is found from the parameter adjustment-candidate energy table, and the corresponding device is controlled to adjust.

[0033] The control module is used to control the operation of one or more modules among the electron gun current adjustment module, the modulator adjustment module, the magnetron magnet adjustment module, and the pulse phase adjustment module, so as to change the ray energy and dose rate output by the accelerator to meet the requirements.

[0049] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] 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.

[0051] The expression of “comprising” an element is an “open” expression, which merely means that a corresponding component or step exists, and should not be interpreted as excluding additional components or steps.

[0052] The following is a brief introduction to the main body of the robot involved in the present invention.

[0053] like Figure 1 As shown, the main body of the robot accelerator mainly includes: a fixed frame 1, a rotating frame 2, a treatment head 3, an imaging system 4, and a robot treatment bed 5. Figure 2 As shown in the figure, the robot accelerator control system includes: main controller, beam generation and monitoring subsystem, robot control subsystem, image acquisition and processing subsystem and collimator subsystem. The main controller manages the system in a unified manner. The entire control system is connected through a high-speed real-time bus. At the same time, the entire control system uses the same synchronization pulse to synchronize the various subsystems. The control commands issued by the main controller, the state information of the acquisition subsystem or the execution of the control commands are all based on the synchronization pulse, ensuring that the treatment pulse of the entire accelerator is strictly synchronized with the image acquisition and motion control to achieve accurate positioning and precise treatment.

[0054] According to the working principle of the electron linear accelerator, the present invention finds that the accelerating electric field, beam load and synchronization conditions are the three basic elements for the stable operation of the accelerator. To change the energy of the rays, these three elements must be taken into consideration. The energy-power (V-P0) characteristics of the standing wave accelerating tube are shown in the following formula:

[0055] V=A(P0) 1 / 2 -kI (1)

[0056] in:

[0057] V is the acceleration energy obtained by the electron beam, and A is the structural coefficient of the accelerating tube, which can be regarded as a constant;

[0058] k is the beam load coefficient, which is related to the accelerating structure of the accelerating tube cavity;

[0059] I is the beam load;

[0060] P0 is the maximum microwave input power obtained by the accelerating tube when the beam load I=0.

[0061] From equation (1), it can be found that the radiation energy of the electron linear accelerator is proportional to the 1 / 2 power of the microwave input power and inversely proportional to the beam load.

[0062] Therefore, in order to achieve the purpose of the present invention, in some embodiments of the method for adjusting the accelerator output energy, as Figure 3 As shown, the adjustment method disclosed in the present invention specifically includes:

[0063] Step S101: determining a number of candidate energy output doses according to actual treatment needs;

[0064] Each candidate value is: the radiation energy and dose rate output by the accelerator;

[0065] For example: 10MV X-ray energy, the dose rates are 1000cGy / min, 800cGy / min and 600cGy / min, etc.;

[0066] 6MV X-ray energy, dose rates of 1200cGy / min, 1000cGy / min, 800cGy / min and 600cGy / min;

[0067] Step S102: by adjusting one or more of the current of the electron gun, the width and amplitude of the pulse current output by the magnetron modulator, the current of the magnetron magnet, and the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron, the ray energy and dose rate output by the accelerator are changed to achieve any candidate energy output dose;

[0068] Step S103: repeat step S102 to obtain the adjustment parameters corresponding to each candidate energy output value, and record them in the parameter adjustment-candidate energy table;

[0069] Step S104: In clinical application, according to any selected candidate energy output dose, the corresponding adjustment parameter is found from the parameter adjustment-candidate energy table, and the corresponding device is controlled to adjust.

[0070] The present invention can adjust appropriate parameters according to the X-ray energy and the corresponding dose rate, such as the current of the sub-gun, the width and amplitude of the pulse current output by the magnetron modulator, the current of the magnetron magnet, the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron, etc., and then record the parameters to form a parameter adjustment-candidate energy table. When in use, the corresponding parameters can be directly called according to the selected ray energy and dose rate to obtain the desired ray energy and dose rate, eliminating the time-consuming real-time parameter adjustment process.

[0071] Specifically, the adjustment scheme of step S102 may include the following situations:

[0072] Case 1: When the width and amplitude of the pulse current output by the magnetron modulator, the current of the magnetron magnet, the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron are fixed,

[0073] That is, under the condition of certain microwave input power, the acceleration energy decreases with the increase of beam load. The greater the current of the electron gun, the smaller the ray energy output by the accelerator.

[0074] Conversely, the greater the accelerator's output radiation energy.

[0075] Specifically: the node controller of the beam generation and monitoring subsystem issues instructions based on the selected output energy and dose rate to change the parameters of the electron gun power supply while keeping the microwave energy input unchanged, that is, the parameters of the fixed modulator unchanged. For example, increasing the pulse current of the electron gun pulse high voltage, that is, increasing the beam load of the accelerating tube, can reduce the X-ray output energy. Conversely, reducing the amplitude of the power supply pulse current can increase the X-ray energy.

[0076] Case 2: When the current of the electron gun, the phase relationship between the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron remains unchanged,

[0077] The larger the width and amplitude of the pulse current output by the magnetron modulator, the greater the energy of the ray output by the accelerator.

[0078] On the contrary, the accelerator outputs smaller radiation energy.

[0079] When the width and amplitude of the pulse current output by the magnetron modulator are adjusted, the current of the magnetron electromagnet is adjusted synchronously to match the input power of the magnetron, so that the magnetron can generate microwaves stably.

[0080] Specifically: the node controller of the beam generation and monitoring subsystem issues instructions to adjust the microwave input power according to the selected output energy and dose rate, that is, to adjust the output pulse current width and amplitude of the modulator. The wider the current width and the larger the amplitude, the greater the energy received by the microwave source magnetron, the greater the microwave energy input to the accelerator tube, and the greater the output X-ray energy. Conversely, the output ray energy will become smaller. While adjusting the modulator output parameters, that is, while the magnetron input pulse, it is also necessary to adjust the current size of the magnetron electromagnet to match the corresponding input power so that it can stably generate microwaves.

[0081] Case 3: When the current of the electron gun, the width and amplitude of the pulse current output by the magnetron modulator, and the current of the magnetron magnet remain unchanged,

[0082] When the electron beam pulse emitted by the electron gun and the microwave pulse of the magnetron are completely synchronized, the accelerator outputs the maximum radiation energy.

[0083] When there is an advance or lag between the two pulses, the energy of the accelerator output radiation will decrease accordingly.

[0084] The electron beam pulses emitted by the electron gun and the microwave pulses of the magnetron are synchronized, and when the pulse width is fixed, the frequency of either pulse can be adjusted to adjust the radiation dose rate while keeping the accelerator output radiation energy stable.

[0085] The higher the trigger pulse, the higher the dose rate, and vice versa.

[0086] Specifically: Figure 4 As shown, the microwaves generated by the magnetron and the electron beams generated by the electron gun are both output to the accelerating tube in pulsed form. The electron beam pulses emitted by the electron gun and the microwave pulses of the magnetron must be strictly synchronized in the resonant cavity of the accelerating tube in order to utilize the microwave electric field to accelerate the electron beam to achieve the required energy.

[0087] Adjusting the relationship between the leading edges of the electron beam pulse and the microwave pulse is to adjust the synchronization of the pulses. If the electron beam pulse and the microwave pulse are strictly aligned, that is, the pulse synchronization is completely maintained, then all the microwave energy can accelerate the electron beam, and the obtained ray energy is the highest. On the contrary, if there is a mutual advance or lag between the two pulses, part of the microwave energy will not be able to accelerate the electron beam, and the obtained ray energy will be reduced. In addition, under the condition of keeping the synchronization relationship stable and the pulse width fixed, adjusting the pulse interval, that is, adjusting the pulse frequency, can adjust the ray dose rate while keeping the ray energy stable.

[0088] Furthermore, the higher the electron beam pulse and microwave pulse, the higher the dose rate, and vice versa.

[0089] In summary, under the premise that other conditions remain unchanged, the electric field strength and thus the output energy of the radiation can be changed by changing the microwave input power. At the same time, after the microwave input power and other conditions are determined, the acceleration energy decreases with the increase of beam load. Secondly, under the conditions that the microwave input power and beam load are determined, changing the beam load, that is, the phase or synchronization relationship between the electron beam pulse emitted by the electron gun and the microwave pulse, can also achieve the purpose of adjusting the output energy of the radiation.
