DETAILED DESCRIPTION

[0011] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but cannot be understood as limiting the present application.

[0012] The terms "first" and "second" etc. in the specification, claims and drawings of the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0013] Arc therapy is a new type of radiotherapy technology. Compared with traditional radiotherapy technology, arc therapy has certain advantages in scanning time, dose distribution and robustness. This technology can flexibly adjust the direction and angle of the beam, greatly improving the adaptability and accuracy of treatment. For tumors that are difficult to remove surgically and tumors with irregular shapes, arc therapy can provide more irradiation angles and directions, better cover tumors, improve the accuracy and precision of treatment, and have good treatment effects. It has good prospects in cancer treatment. However, in order to realize arc therapy, strong software and hardware support is required. Conventional rotating racks have high technical and economic cost requirements for arc therapy software and hardware; in addition, these hardware devices are usually large and occupy a large space. This makes the cost of arc therapy high.

[0014] In addition, arc therapy requires the treatment equipment to be able to accurately position and control the irradiation of proton beams at multiple angles and directions, which places very high demands on the mechanical accuracy, motion control system, equipment rotation time, and image guidance system of the equipment. Arc therapy requires the treatment equipment to operate for a long time and with high precision, so the quality and stability of the equipment are very strict. Any failure or error of the equipment may affect the treatment effect and even cause harm to the patient. Therefore, it is necessary to establish a complete equipment quality control and maintenance system, and regularly inspect and maintain the equipment to ensure the normal operation of the equipment. The cost of the corresponding equipment for arc therapy is high, and professional technicians are required to maintain and service it, which increases the cost of the equipment. Due to its high cost, the treatment costs that patients need to bear are also high, so arc therapy is difficult to be widely used, affecting the accessibility of treatment.

[0015] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0016] Figure 1 A schematic flow chart of an arc irradiation method provided by an exemplary embodiment of the present application, the method at least includes the following steps S101-S103: S101, obtaining an arc treatment plan, wherein the arc treatment plan includes a plurality of irradiation fields, an irradiation angle set corresponding to each irradiation field, and a beam energy corresponding to each first irradiation angle among a plurality of first irradiation angles included in each irradiation angle set; Optionally, the irradiation field refers to a lesion sub-region in the lesion surface of the patient.

[0017] Optionally, the arc treatment plan may be set based on a treatment planning system that supports the arc treatment plan. Specifically, the treatment planning system may obtain tumor information of the patient and formulate an arc treatment plan corresponding to the patient based on the tumor information of the patient.

[0018] S102, obtaining the current angle between the lesion surface of the patient sitting on the treatment chair and the irradiation direction; Optionally, in order to ensure the safety of the patient and the equipment, when the patient sits on the treatment chair, the patient and the treatment chair are locked. Specifically, the safety interlocking system can be activated to lock the patient and the treatment chair using the safety interlocking system.

[0019] Optionally, the current angle is determined by the irradiation angle set in the arc treatment plan and the registration vector provided by the seated image guidance system, wherein the registration vector is applied to the angles in the irradiation angle set corresponding to all irradiation fields in the arc treatment plan. For example, when the treatment chair rotates, the treatment chair rotates, and the patient also rotates, and the angle between the lesion surface of the corresponding patient and the irradiation direction will be different. The image acquisition of the seated image guidance system can be used for precise positioning to ensure that the lesion surface of the patient is irradiated at an accurate irradiation angle, so that the lesion surface of the patient can always be in the best irradiation position.

[0020] S103. For each irradiation field, adjust the treatment chair of the patient according to the irradiation field and the current angle, so as to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient.

[0021] Optionally, a beam may be emitted by a beam emitting device, and the energy of the beam may be used to irradiate the lesion sub-region.

[0022] Optionally, the method further includes: sorting the multiple irradiation fields in ascending order according to the starting angle or the ending angle in the irradiation angle set corresponding to each irradiation field, to obtain an irradiation field sorting; in the aforementioned S103, for each irradiation field, adjusting the patient's treatment chair according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient, including: according to the irradiation field sorting, for each irradiation field, adjusting the patient's treatment chair according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient.

[0023] Optionally, the lesion sub-areas corresponding to the respective irradiation fields in the plurality of irradiation fields may be irradiated in sequence according to the irradiation field sequence.

[0024] Optionally, multiple irradiation fields may be sorted according to the irradiation field sorting, and the sorted multiple irradiations may be combined to irradiate as a target irradiation field. Specifically, after the target irradiation field is acquired, the patient's treatment chair is adjusted using the target irradiation field and the current angle to irradiate the patient's lesion surface.

[0025] Optionally, in the aforementioned S103, the treatment chair of the patient is adjusted according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient, including: for each first irradiation angle in the irradiation angle set corresponding to the irradiation field, the treatment chair of the patient is adjusted so that the angle between the lesion surface of the patient and the irradiation direction is the first irradiation angle, and the lesion sub-area corresponding to the irradiation field is irradiated with the beam energy corresponding to the first irradiation angle.

[0026] Optionally, when the lesion sub-area corresponding to the irradiation field is irradiated with the beam energy corresponding to the first irradiation angle, the method further includes: when the first irradiation angle is the end angle in the irradiation angle set corresponding to the irradiation field and is not the start angle in the irradiation angle set corresponding to the next irradiation field of the irradiation field, no irradiation is performed.

[0027] Optionally, during the irradiation process, the laser positioning system and the safety interlock system together determine whether the patient's position has changed. When the position has changed, the beam emission is interrupted in time through the joint action of the accelerator, the transport line system and the scanning dose system. When the patient's position is repositioned, the beam emission can be continued or the treatment can be terminated. Among them, the patient's position is repositioned means that the patient is rotated to the next irradiation angle of the current irradiation field, or the starting angle of the next irradiation field, or rotated to the initial position of the patient for the first irradiation. If the patient is rotated to the initial position of the patient for the first irradiation, it means that multiple irradiation fields of the patient have been irradiated. At this time, the irradiation has been completed, and the beam emission can be stopped, and the irradiation can be stopped.

[0028] Optionally, the method also includes: when the first irradiation angle is the end angle in the irradiation angle set corresponding to the irradiation field and is the starting angle in the irradiation angle set corresponding to the next irradiation field of the irradiation field, irradiation is performed with the beam energy corresponding to the starting angle in the irradiation angle set corresponding to the next irradiation field.

[0029] Optionally, when the treatment chair rotates to a starting angle corresponding to a next irradiation field, a beam with a beam energy corresponding to the starting angle is emitted to irradiate a lesion sub-region corresponding to the next irradiation field.

[0030] Optionally, the lowest energy of the beam energies corresponding to the first irradiation angles in the irradiation angle set corresponding to the next irradiation field is greater than the highest energy of the beam energies corresponding to the first irradiation angles in the irradiation angle set corresponding to the irradiation field.

[0031] Optionally, the beam energy in the one irradiation field decreases gradually.

[0032] In summary, an arc treatment plan is obtained, wherein the arc treatment plan includes multiple irradiation fields, an irradiation angle set corresponding to each irradiation field, and a beam energy corresponding to each first irradiation angle in a plurality of first irradiation angles included in each irradiation angle set; the current angle between the lesion surface of the patient sitting on the treatment chair and the irradiation direction is obtained; for each irradiation field, the patient's treatment chair is adjusted according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the patient's lesion surface. By adjusting the angle of the treatment chair, the patient can be irradiated in an annular manner, so that arc irradiation can be achieved for the patient even without special equipment based on arc irradiation, which reduces the cost of arc irradiation and enables arc treatment to be widely used.

[0033] Specifically, an automatically rotating treatment chair is used to drive the patient to rotate, adjust to different irradiation fields, and adjust to different irradiation angles of the same irradiation field, so as to achieve arc treatment at different irradiation angles for the patient. This solution does not require a high-precision, complex arc treatment system, and achieves miniaturization and lightweight arc treatment. A fixed beam output device and a rotating treatment chair are used to replace conventional rotating frames and treatment beds, and the multi-angle arc irradiation requirements of a fixed beam are met. Multiple irradiation fields are merged into one irradiation field, and automatically switched to different irradiation fields for irradiation, thereby improving the efficiency of treatment. Redundant processes such as manual selection of different irradiation fields for irradiation and confirmation of irradiation angles are reduced, saving treatment time.

[0035] Optionally, the multiple first irradiation angles include a starting irradiation angle and an ending irradiation angle, and the device is further used to: sort the multiple irradiation fields in ascending order according to the starting angle or the ending angle in the irradiation angle set corresponding to each irradiation field, to obtain an irradiation field sorting; for each irradiation field, adjust the patient's treatment chair according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient, including: according to the irradiation field sorting, for each irradiation field, adjust the patient's treatment chair according to the irradiation field and the current angle to irradiate the lesion sub-area corresponding to the irradiation field in the lesion surface of the patient.

[0037] Optionally, when the device irradiates the lesion sub-area corresponding to the irradiation field with the beam energy corresponding to the first irradiation angle, the device is also used to: not irradiate when the first irradiation angle is the end angle in the irradiation angle set corresponding to the irradiation field and is not the start angle in the irradiation angle set corresponding to the next irradiation field of the irradiation field.
