Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

With the continuous development of the times and the continuous improvement of science, medical technology and medical equipment are also continuously improved so as to provide better treatment and service for patients. Especially, diseases such as tumor, cancer and the like can not be treated only by means of operation, and sometimes radiotherapy technology is indispensable in the treatment process; the accelerator is a key device of radiotherapy equipment, so the static magnetic field distribution condition of the accelerator and the research on a generating device also occupy an extremely important position; the accelerator is applied in the medical field, and the related particles are continuously accelerated by the accelerator to obtain quite high speed and thus have high energy, so that the accelerator has the effects of cutting off tumors and killing cancer cells.

The inventor finds that at present, the magnetic field change of an accelerator in medical equipment used in the radiotherapy process is complex and various, so that the whole magnetic field system needs to be accurately adjusted on the basis of the measurement by adopting a magnetic needle, the adjustment step is complicated, the requirement is high, the operation is complex, the debugging time of an operator is long, and the requirements of fast adjustment and whole operation time shortening are difficult to meet.

The purpose of the present disclosure is to provide a magnetic field adjusting device and method for an accelerator, and an accelerator, which are used for adjusting the magnetic field of the accelerator by setting a plurality of sets of magnetic field mechanisms and matching with corresponding accelerating mechanisms, and using the difference of iron core materials in different magnetic field mechanisms without adjusting power supply parameters, so as to enable the magnetic field mechanisms to generate different magnetic fields, thereby adapting to the strength of magnetic fields with different requirements, rapidly obtaining the strength of the required magnetic field, and shortening the time of the whole operation.

The first purpose of the present disclosure is to provide a method for adjusting a magnetic field of an accelerator, which adopts the following technical scheme:

the method comprises the following steps:

the magnetic field mechanisms are sequentially arranged in a plurality of groups, and generate magnetic fields with different strengths after being respectively electrified;

the accelerating mechanism in each group of magnetic field mechanism outputs particles with different speeds under the action of different magnetic field mechanisms;

and selecting a magnetic field mechanism which correspondingly works according to the speed of the required particles, electrifying and outputting the required particles.

The second purpose of the present disclosure is to provide an accelerator magnetic field adjusting device, which adopts the following technical solutions:

the method comprises the following steps:

the magnetic field mechanisms are sequentially provided with a plurality of groups and are configured to generate magnetic fields with different strengths after being electrified;

the acceleration mechanisms are arranged in the multiple groups of magnetic field mechanisms in a one-to-one correspondence manner and are configured to accelerate and output the particles in the acceleration mechanisms under the action of corresponding magnetic fields;

and the switching mechanism is configured to acquire an external command and electrify the corresponding magnetic field mechanism to enable the corresponding acceleration mechanism to output the required particles.

Furthermore, the magnetic field mechanism comprises two polar plates which are oppositely arranged, and the two polar plates are respectively connected with an external power supply and used for generating a uniform magnetic field between the two polar plates.

Furthermore, the pole plates are electromagnets with iron cores, and the pole plates of different groups of magnetic field mechanisms are made of different iron core materials and used for enabling the different groups of magnetic field mechanisms to generate different magnetic fields under the same electrifying condition.

Further, the acceleration mechanism comprises two D-shaped boxes, and the particles are accelerated in the D-shaped boxes and then output.

Further, the D-shaped box is located in a uniform magnetic field area in the magnetic field mechanism.

Furthermore, the magnetic field mechanism is matched with an adjusting circuit for finely adjusting the intensity of the magnetic field in the corresponding magnetic field mechanism, so that the accelerating mechanism under the action of the magnetic field mechanism outputs particles with different speeds.

A third object of the present disclosure is to provide an operating method based on an accelerator magnetic field adjusting device, which includes the following steps:

selecting a magnetic field mechanism to be started according to the required particle state, and electrifying the magnetic field mechanism;

the accelerating mechanism accelerates the particles to a required state under the action of the magnetic field mechanism and then outputs the particles, and acts on a set position;

when the demands are different, different magnetic field mechanisms are switched to be electrified according to the demands, and particles in the required state are output.

Further, when the output particle state after all the magnetic field mechanisms are electrified cannot meet the requirement, the current introduced into the magnetic field mechanisms is adjusted, and therefore the required particle state is obtained.

A fourth object of the present application is to provide an accelerator, which utilizes an accelerator field adjustment device as described above.

(1) the magnetic fields are sequentially arranged, different magnetic fields can be generated under the same power-on state by arranging different polar plate materials, and particles with different speeds are correspondingly output, so that different radiotherapy requirements are met, the rapid switching under different requirements is realized, and the time for adjusting a magnetic field system is reduced;

(2) the electromagnet is used as a pole plate material, so that on one hand, magnetic consumption generated during the period of non-use can be avoided, the service life is prolonged, and on the other hand, the magnetic force of the pole plate can be accurately adjusted by adjusting power supply parameters, so that the magnetic field intensity between the two pole plates is accurately adjusted, and the adaptability of the pole plate is improved; the coarse adjustment and the fine adjustment are respectively realized by matching with a magnetic field switching mechanism, so that the magnetic field intensity is quickly adjusted; on the other hand, when the electromagnet is not electrified, magnetic field interference cannot be generated on other electrified electromagnets, and the magnetic field parameter precision of the electromagnet is improved.
