Description

Treatment part carrying device and radiotherapy system TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a carrying device and a radiotherapy system. BACKGROUND

[0002] With the development of atomic science, radiotherapy such as cobalt-60, linear accelerator, electron beam, etc. has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the radiation itself, which not only kills tumor cells but also causes damage to a large number of normal tissues along the beam path; in addition, due to the different sensitivity of tumor cells to radiation, the treatment effect of traditional radiotherapy on malignant tumors with high radiation resistance (such as Glioblastoma Multiforme and Melanoma) is often poor.

[0003] In order to reduce the radiation damage to normal tissues around the tumor, the concept of targeted therapy in chemotherapy is applied to radiotherapy; and for tumor cells with high radiation resistance, radiation sources with high relative biological effectiveness (RBE) are actively developed, such as proton therapy, heavy particle therapy, and neutron capture therapy. Among them, neutron capture therapy is a combination of the above two concepts, such as Boron Neutron Capture Therapy (BNCT), which provides a better cancer treatment option than traditional radiation by specific accumulation of boron-containing drugs in tumor cells and precise neutron beam control.

[0004] In the process of tumor radiotherapy, such as the treatment process of BNCT, after the treatment part of the irradiated body is moved to the actual treatment or simulated positioning position according to the target position in the treatment plan scheme formulated by the treatment planning system (TPS), accurate adjustment and positioning are required. Therefore, a technical means is needed to accurately and adjustably position the treatment part of the irradiated body, and should have the characteristics of simple installation, short operation time, high accuracy and easy operation.

DETAILED DESCRIPTION

[0071] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0072] During the radiotherapy of tumors, due to the existence of factors such as fixing deviation, human error and equipment failure, the actual treatment or simulated positioning position may deviate from the target irradiation position preset in the treatment plan. The positioning deviation of the irradiated body during preparation and treatment will affect the center position of the lesion target area. If the positioning error is too large, the center position of the lesion target area is prone to deviation. Once the treatment is started incorrectly, the dose given to the irradiated body is inaccurate, which leads to insufficient irradiation dose of the tumor target area or excessive irradiation dose of the surrounding normal tissue, thereby bringing adverse effects and failing to achieve the desired treatment effect.

[0073] In order to achieve good treatment effect, the irradiated body can adopt multiple body position treatment methods, and can also be reliably supported and accurately positioned by the bearing device. In addition, the irradiated body needs to maintain a fixed posture during a period of treatment, so the treatability, rationality and comfort of the posture during positioning are also considered. For example, for the treatment of lesions in the head and neck, the headrest device for fixing the head and neck usually needs to be moved or adjusted during treatment. Since the important organs of the head and neck are concentrated, the relationship between each organ is complex, and the positioning accuracy of the head and neck has an important influence on the subsequent treatment effect of the head and neck. During treatment, the embodiments of the present application can accurately position the irradiated body, shorten the preparation time and improve the positioning efficiency, and also can ensure that the irradiated body is positioned in a relatively comfortable treatment position during the treatment period.

[0074] With reference to FIGS. 1 to 9, the embodiments of the present application provide a treatment part bearing device, which is used for at least partially bearing a treatment part. The treatment part bearing device comprises a bearing unit 10 and an adjusting assembly 20. The bearing unit 10 is used for at least partially bearing the treatment part. The adjusting assembly 20 is connected with the bearing unit 10 and is used for driving the bearing unit 10 to realize rotation and / or translation adjustment.

[0075] Overall, when using the treatment part bearing device, the treatment part bearing device is arranged at the actual irradiation position (such as one side of the beam exit 40 in FIG. 10), as close as possible to the target irradiation position in the treatment plan. The treatment part is carried by the bearing unit 10, which is beneficial to improve the fixing effect of the treatment part and avoid the change of the relative position between the actual irradiation position and the target irradiation position during treatment.

[0076] Generally, in the preparation and treatment process, the positioning position of the treatment part affects its actual irradiation position, such as the center position of the lesion target region relative to the beam exit 40, and when the treatment part is the head and neck, the positioning accuracy requirement of the treatment part is higher. The present application connects the bearing unit 10 with the adjustment assembly 20, so as to drive the bearing unit 10 to realize rotation and / or translation adjustment by using the mechanical structure in the adjustment assembly 20, so that the bearing unit 10 and the treatment part thereon can be adjusted in at least one degree of freedom direction, thereby accurately controlling the position of the treatment part, such as the positioning position of the lesion target region, which helps to reduce or eliminate the positioning error between the actual irradiation position and the target irradiation position of the treatment part, further improves the positioning efficiency and positioning accuracy, shortens the preparation time of positioning and simplifies the preparation work, and makes the treatment part as close as possible to the target irradiation position and keeps for a certain time, thereby being beneficial to improve the subsequent treatment effect.

[0077] In some embodiments of the present application, the adjustment assembly 20 includes a rotation adjustment unit 100 capable of driving the bearing unit 10 to perform rotation adjustment in at least one degree of freedom direction; and / or a translation adjustment unit 200 capable of driving the bearing unit 10 to perform translation adjustment in at least one degree of freedom direction.

[0078] In some embodiments, the adjustment assembly 20 includes a rotation adjustment unit 100 capable of driving the bearing unit 10 to perform rotation adjustment in at least one degree of freedom direction. The rotation adjustment unit 100 can drive the bearing unit 10 to perform rotation adjustment, improving the rotation adjustment flexibility of the bearing unit 10 and the treatment part thereon.

[0079] In some embodiments, the adjustment assembly 20 includes a translation adjustment unit 200 capable of driving the bearing unit 10 to perform translation adjustment in at least one degree of freedom direction. The translation adjustment unit 200 can drive the bearing unit 10 to perform translation adjustment, improving the translation adjustment flexibility of the bearing unit 10 and the treatment part thereon.

[0080] In some embodiments, the adjustment assembly 20 includes a rotation adjustment unit 100 capable of driving the bearing unit 10 to perform rotation adjustment in at least one degree of freedom direction; and a translation adjustment unit 200 capable of driving the bearing unit 10 to perform translation adjustment in at least one degree of freedom direction.

[0081] By combining the use of the rotation adjustment unit 100 and the translation adjustment unit 200, the bearing unit 10 can be driven to perform both rotation adjustment and translation adjustment, improving the adjustment flexibility of the bearing unit 10 and further improving the positioning accuracy of the treatment part.

[0082] In some embodiments of the present application, such as the embodiments shown in FIG. 1 and FIG. 2, the adjusting assembly 20 comprises a support unit 300, through which the carrying unit 10 is connected with the translational adjusting unit 200 and / or the rotational adjusting unit 100.

[0083] In some embodiments, when the adjusting assembly 20 comprises the rotational adjusting unit 100, the carrying unit 10 is connected with the translational adjusting unit 200 through the support unit 300.

[0084] In some embodiments, when the adjusting assembly 20 comprises the translational adjusting unit 200, the carrying unit 10 is connected with the rotational adjusting unit 100 through the support unit 300.

[0085] In some embodiments, when the adjusting assembly 20 comprises both the rotational adjusting unit 100 and the translational adjusting unit 200, the carrying unit 10 is connected with the translational adjusting unit 200 and the rotational adjusting unit 100 through the support unit 300. Preferably, the carrying unit 10 is connected with the rotational adjusting unit 100 through the support unit 300, and the rotational adjusting unit 100 can be connected with the translational adjusting unit 200.

[0086] The connection between the carrying unit 10 and the rotational adjusting unit 100 through the support unit 300 improves the stability of the connection between the carrying unit 10 and the adjusting assembly 20.

[0087] The support unit 300 can also provide a certain installation allowance, so as to avoid interference between the carrying unit 10 and the rotational adjusting unit 100 during use and affect the use of the equipment.

Specifically, the bearing unit 10 which has completed the relative fixation, the first support 310 and the second support 320, and the first adjusting structure 110 located on the second support 320 can be transferred to the irradiation room, and thus, in the irradiation room, since the second adjusting structure 120 of the adjusting assembly 20 and the translation adjusting unit 200 can be rapidly adjusted according to the adjustment parameters of the simulation positioning, only the direct fixed connection of the second support 320 with the fourth shell 122 of the adjusting assembly 20 can realize the accurate positioning of the irradiated body in the irradiation room, which can reduce the radiation dose of the patient and medical staff.

[0166] In some embodiments of the present application, the adjustment assembly 20 includes a rotation adjustment unit 100 capable of driving the carrying unit 10 to perform rotation adjustment in at least one degree of freedom direction; and / or a translation adjustment unit 200 capable of driving the carrying unit 10 to perform translation adjustment in at least one degree of freedom direction. The specific structure and function of the rotation adjustment unit 100 and the translation adjustment unit 200 can be referred to the description in the foregoing embodiments, and will not be repeated here.

[0167] In some embodiments, the adjustment assembly 20 includes a rotation adjustment unit 100, which can drive the carrying unit 10 to perform rotation adjustment in at least one degree of freedom direction.

[0168] Preferably, the rotation adjustment unit 100 can drive the carrying unit 10 to perform rotation adjustment in two degrees of freedom directions, i.e. a first preset axis direction and a second preset axis direction. Preferably, the first preset axis is perpendicular to the second preset axis.

[0169] In some embodiments, the adjustment assembly 20 comprises a translation adjustment unit 200, by which the carrier unit 10 can be driven to perform translation adjustment in at least one degree of freedom.

[0170] Preferably, the carrier unit 10 can be driven to perform translation adjustment in three degrees of freedom, i.e. the first degree of freedom F1, the second degree of freedom F2 and the third degree of freedom F3, by the translation adjustment unit 200. Preferably, the first degree of freedom F1 is a vertical direction, the second degree of freedom F2 is a horizontal direction, and the third degree of freedom F3 is a horizontal direction and perpendicular to the second degree of freedom F2.

[0171] In some embodiments, the adjustment assembly 20 comprises a rotation adjustment unit 100 and a translation adjustment unit 200, by which the carrier unit 10 can be driven to perform rotation adjustment and / or translation adjustment.

[0172] In some embodiments of the present application, the translation adjustment unit 200 is connected with the rotation adjustment unit 100, and at least one translation axis of the translation adjustment unit 200 coincides with one rotation axis of the rotation adjustment unit 100.

[0173] By coinciding the translation axis of the translation adjustment unit 200 with the rotation axis of the rotation adjustment unit 100, a certain positional relationship between the translation adjustment unit 200 and the rotation adjustment unit 100 is formed, which facilitates the control of the positioning position of the carrier unit 10, and thus helps to improve the positioning efficiency and positioning accuracy. Preferably, the second preset axis coincides with the first degree of freedom F1.

[0174] In some embodiments of the present application, the beam exit 40 comprises a central axis M (such as an axis perpendicular to the beam exit plane), and the translation adjustment unit 200 adjusts the relative position between the treatment portion and the beam exit 40 at least in a direction parallel to the central axis M, such as the second degree of freedom F2 in some embodiments is parallel to the direction of the central axis.

[0175] Further, the radiotherapy system comprises a beam shaping body 50 for forming a beam after energy spectrum adjustment of the particles, and the carrying device comprises an external structure 400, and the external structure 400 of the carrying device is used for fixing the adjustment assembly 20 on the beam shaping body 50. The specific shape of the external structure 400 can be adjusted according to the installation needs, which is not specifically limited here. Preferably, the external structure 400 comprises at least one external part connected with the third static base 231. The external part comprises an external block. In some embodiments, the external base plate is fixedly arranged outside the beam shaping body 50 of the radiotherapy system, and the external base plate comprises a quick-mounting structure matched with the external block on the adjustment assembly 20. By quickly mounting the external block on the quick-mounting structure, the adjustment assembly 20 can be conveniently mounted on the beam shaping body 50 as a whole. Preferably, the quick-mounting structure can be quickly mounted without additional assembly tools, further shortening the assembly time of the adjustment assembly 20, and being beneficial to subsequent positioning and treatment.

[0176] In some embodiments, the carrying unit 10 comprises but is not limited to a carrier (not shown) and / or a thermoplastic film (not shown) and the like. Further, the thermoplastic head film can be fixedly connected with the head support, and the head and neck of the irradiated body can be more reliably fixed at the target irradiation position, such as near the beam outlet 40 on one side of the beam shaping body 50, during the adjustment and positioning of the adjustment assembly 20, so as to accurately position and treat the lesion target area of the head and neck of the irradiated body.

[0177] In some embodiments, the radiotherapy system can adopt a neutron capture therapy system (BNCT), and specifically, the particle generating device 30 comprises a neutron generating device for generating radiation with a neutron beam, and making the neutron beam N emit from the beam outlet 40.

[0178] Specifically, the neutron generating device disclosed in the embodiment of the present application comprises an accelerator and a target material T, the accelerator is used for accelerating protons and generating a proton line P, the proton line P irradiates the target material T and interacts with the target material to generate neutrons, and the neutrons form a neutron beam N and emit from the beam outlet 40. The positions of the carrying device and the irradiated body can be adjusted by the adjustment assembly 20, so that the neutron beam N is aligned with the tumor cells in the irradiated body.

[0179] The direction of the neutron beam N in the figure does not represent the actual absolute motion direction of the neutrons, but represents the direction of the overall motion trend of the neutron beam N. Suitable nuclear reactions can be selected according to the required neutron yield and energy, the available accelerating charged particle energy and current size, and the physicochemical properties of the target material. The specific structure of the accelerator and the target material is not described in detail here.

[0180] It is easily understood that in other embodiments, the neutron generating device can also have other configurations, such as not using an accelerator to generate a neutron source, but also in the form of a reactor, an ion source, etc. The radiation therapy particles include but are not limited to neutrons, and also include protons, heavy ions and other particle therapy.

[0181] The particle generating device 30 further comprises a beam shaping body 50 for adjusting the beam quality of the neutron beam, which is embedded in the wall of the irradiation chamber and the preparation chamber, for adjusting the beam quality of the neutron beam N. Further, by fixing the external structure 400 on the beam shaping body 50, and connecting the adjustment assembly 20 through the external structure 400, a reliable positioning reference can be provided for the adjustment assembly 20, so that the adjustment assembly 20 can be provided with stable support force through the beam shaping body 50, and further facilitate the position adjustment of the carrying unit 10 under the action of the adjustment assembly 20.

[0182] The beam shaping body further comprises a reflector, a moderator, a thermal neutron absorber, and a radiation shielding body. The neutrons generated by the neutron generating device have a very wide energy spectrum. In addition to the epithermal neutrons meeting the treatment needs, it is necessary to reduce the content of other types of neutrons and photons as much as possible to avoid harm to the operators or the irradiated body. Therefore, the neutrons coming out of the neutron generating device need to pass through the moderator to adjust the fast neutron energy (>40keV) in it to the epithermal neutron energy region (0.5eV-40keV) and reduce the thermal neutron content (<0.5eV) as much as possible. The moderator is made of materials with large fast neutron interaction cross section and small epithermal neutron interaction cross section. As a preferred embodiment, the moderator is made of D2O, AlF3, Fluental TMThe reflector surrounds the moderator and reflects neutrons diffused around the moderator back to the neutron beam N to improve the utilization of neutrons, and is made of a material having a strong neutron reflecting ability, and as a preferred embodiment, the reflector is made of at least one of Pb and Ni. The moderator is provided with a thermal neutron absorber at the rear thereof, and is made of a material having a large thermal neutron interaction cross section, and as a preferred embodiment, the thermal neutron absorber is made of Li-6. The thermal neutron absorber is used to absorb thermal neutrons passing through the moderator to reduce the content of thermal neutrons in the neutron beam N, so as to avoid causing excessive dose to the shallow normal tissue during treatment. It can be understood that the thermal neutron absorber can also be integrated with the moderator, and the material of the moderator contains Li-6. The radiation shielding body is used to shield the neutrons and photons leaking from the part other than the beam exit 40, and the material of the radiation shielding body includes at least one of a photon shielding material and a neutron shielding material, and as a preferred embodiment, the material of the radiation shielding body includes the photon shielding material Pb and the neutron shielding material PE. The super-thermal neutron beam from the beam exit 40 irradiates the irradiated body, and after passing through the shallow normal tissue, is moderated to thermal neutrons to reach the tumor cells. It can be understood that the beam shaper 50 can also have other configurations, as long as the super-thermal neutron beam required for treatment can be obtained.

[0183] It can be easily understood that the radiotherapy system is generally arranged integrally in a medical facility, and the medical facility can include a preparation room in addition to a treatment room for generating a beam and treating the irradiated body 60. The preparation room can be a general term for all facilities performing various steps before the completion of the determination of the position before treatment, and can include a preparation room for image acquisition, a preparation room for positioning, a preparation room for drug supply, etc.

[0184] In order to ensure the accuracy of the positioning and the determination of the treatment plan, the facilities in part of the preparation room are preferably arranged in a manner that the relative position of the core equipment (such as the beam exit 40) of the treatment room is basically the same. The treatment room includes a partition wall, a corresponding beam shaper 50 and / or a collimator, and correspondingly, the preparation room for simulating the positioning can include a simulation collimator with the same shape, which is used as a reference datum for simulating the beam exit 40.

[0185] In order to make the positioning of the irradiated body 60 more accurate when switching between different preparation rooms, or to make the positioning more accurate when switching between the preparation room and the treatment room, a physical reference system, such as a laser reference system, etc., can also be arranged in the preparation room or the treatment room for pre-positioning before image acquisition, positioning or irradiation.

[0186] The physical reference frame fiducials provided in the preparation room and the treatment room should be kept as consistent as possible, such as when different spaces use laser reference frames, the three laser vertical planes formed thereby have a unique intersection point, which serves as a fiducial that should be calibrated as much as possible to the same position relative to the beam exit 40 in the preparation room and the treatment room.

[0187] Therefore, in the preparation room and / or the treatment room of the radiotherapy system, the positioning efficiency and positioning accuracy of the carrying unit 10 in the preparation process and the treatment process can be improved by using the carrying device in the foregoing embodiments, the preparation time for positioning is shortened, the preparation work is simplified, and the subsequent treatment effect is improved.
