[0056] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0057] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0058] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0059] The present invention provides a proton therapy device and a control method thereof, which relate to the field of image-guided radiotherapy technology and are suitable for solving the collision risk of existing proton therapy devices, as well as the technical problem that the existing devices have poor imaging quality and cannot be used for adaptive treatment. The present invention adopts a closed skin design to avoid the collision risk caused by the exposure of mobile devices. In addition, the fan beam CT used in the present invention can achieve diagnostic-level image accuracy, improve image guidance accuracy, reduce positioning errors, and can be applied to treatment planning. The following is a detailed description through specific embodiments.

[0060] See also Figure 1In one embodiment of the present invention, the proton therapy device may include a device body 100, a treatment bed 200, a detection assembly 300, a treatment assembly 400 and a processor 500. Among them, a treatment cabin 110 is arranged in the device body 100. The treatment bed 200 is movably arranged on the device body 100, which can be used to carry the patient 600 and drive the patient 600 to move along the axis direction of the treatment cabin 110. The detection assembly 300 can be rotatably connected to the device body 100, which can be used to collect CT image data of the patient's lesion. The treatment assembly 400 can be rotatably connected to the device body 100, which can be used to perform proton beam irradiation therapy. The processor 500 is electrically connected to the treatment bed 200, the detection assembly 300 and the treatment assembly 400 respectively, and can be used to control the operation of the treatment bed 200, the detection assembly 300 and the treatment assembly 400. In this embodiment, the processor 500 can be used to first control the detection component 300 to collect CT image data of the patient's lesion; then, reconstruct the CT image data collected by the detection component 300 to generate a three-dimensional CT image of the patient's lesion; and then align the treatment plan image of the patient 600 with the three-dimensional CT image to generate the positioning deviation data. In this embodiment, the positioning deviation data can represent the position deviation value between the actual position of the patient's lesion and the preset treatment position in the treatment plan image. The processor 500 is also used to control the treatment bed 200 to drive the patient 600 to move to the corresponding treatment position based on the positioning deviation data. When the patient 600 moves to the preset treatment position, the processor 500 can control the treatment component 400 to perform proton beam irradiation treatment on the patient's lesion.

[0061] As can be seen from the above, the treatment cabin 110 adopts a hole-shaped design, and the treatment bed 600 carries the patient 600 into the treatment cabin 110 to receive radiation treatment. The equipment body 100 adopts a closed skin design, and the detection component 300 and the treatment component and other mobile devices are arranged in the equipment body 100 to avoid the risk of collision. In this embodiment, a closable maintenance window can also be provided on the equipment body 100, and the position of the maintenance window can correspond to the detection component 300 and the treatment component 400 to facilitate maintenance and replacement of both.

[0062] See also Figure 1 , Figure 2In one embodiment of the present invention, the detection assembly 300 may include a detection rack 310 and a detection module 320. The detection rack 310 may be rotatably connected to the equipment body 100, and may be specifically arranged around the outside of the treatment cabin 110. The detection module 320 may be fixedly connected to the detection rack 310. It can be seen that the detection rack 310 may drive the detection module 320 to rotate around the treatment cabin 110, thereby collecting CT image data of the patient 600 from multiple angles. In this embodiment, the treatment bed 200 drives the patient 600 to move along the axial direction of the treatment cabin 110, and at the same time, the detection rack 310 drives the detection module 320 to rotate around the treatment cabin 110, thereby realizing spiral scanning imaging of the patient 600 and generating continuous tomographic images of the patient.

[0063] In one embodiment of the present invention, the detection module 320 may use a sector CT (Computed Tomograhy) imaging device. Sector CT images the human body section by emitting a sector beam of X-rays, and then generates data for each section (layer), that is, generates a two-dimensional image. Compared with cone beam CT (CBCT, Cone Beam Computed Tomography), sector CT can provide images with higher resolution, which is crucial for diagnosis and treatment planning. In the prior art, due to the hardware limitations of cone beam CT imaging algorithms and flat panel detectors, the imaging treatment of cone beam CT cannot be compared with the fan beam CT used in diagnostic equipment, so that the use of image guidance in radiotherapy is subject to certain restrictions. Especially in the case of requiring detailed anatomical structure information, such as lung disease diagnosis, sector CT can provide clear cross-sectional images and can be reconstructed into three-dimensional images through software, while the imaging effect of cone beam CT for soft tissue is not as good as sector CT, and the contrast and details of soft tissue in cone beam CT imaging cannot reach the diagnostic level. The present invention uses fan beam CT to improve the quality of image guidance.

[0064] See also Figure 1 , Figure 2In one embodiment of the present invention, the detection module 320 may include a high voltage generator 321, a tube 322, a sector detector 323 and a processing unit (not shown in the figure). Among them, the high voltage generator 321 may be fixedly connected to the detection frame 310, and it can be used to generate high voltage current. The tube 322 may be fixedly connected to the detection frame 310. The sector detector 323 may be fixedly connected to the detection frame 310, and the sector detector 323 is located at a position opposite to the tube 322. Specifically, the sector detector 323 may be a fan ring body, and the output port of the tube 322 may be located at the center of the fan ring formed by the high voltage generator 323. In this embodiment, the high voltage generator 321 may be used to provide a high voltage current to the tube 322. The tube 322 generates a fan beam X-ray based on the high voltage current provided by the high voltage generator 321. The tube 322 may include a cathode and an anode. When a high voltage is applied to both ends of the tube 322, electrons are accelerated from the cathode and collide with the anode, thereby generating X-rays. The sector detector 323 may be composed of a plurality of detection units, which may be used to receive X-ray signals after passing through the body of the patient 600. Each detection unit may measure the intensity of the received X-rays and convert them into electrical signals. These electrical signals are then transmitted to the processing unit for processing and image reconstruction to generate CT image data.

[0065] See also Figure 1 , Figure 3 In one embodiment of the present invention, the treatment assembly 400 may include a treatment frame 410 and a proton therapy module 420. The treatment frame 410 may be rotatably connected to the device body 100, and may be specifically arranged around the outside of the detection frame 310. The output end of the proton therapy module 420 may be fixedly connected to the treatment frame 410. In this embodiment, the treatment frame 410 may drive the output end of the proton therapy module 420 to rotate around the treatment cabin 110, so as to perform proton beam irradiation therapy on the patient's lesions from multiple angles.

[0066] See also Figure 1 and Figure 3In one embodiment of the present invention, the proton therapy module 420 may include an acceleration unit (not shown in the figure), a transport unit 421 and an irradiation unit 422. The acceleration unit may be, for example, a cyclotron or a synchrotron, which may be used to provide a high-energy proton beam. The transport unit 421 may be used to guide the proton beam to a specified position. The transport unit 421 may be, for example, a beam transport line, in which a vacuum state is usually maintained to reduce the interaction between protons and air molecules. The irradiation unit 422 is the output end of the proton therapy module 420, which is connected to the treatment rack 410, and may be used to accurately transport the proton beam guided by the transport unit 421 to the patient's lesion. It can be seen that the treatment rack 410 can drive the irradiation unit 422 to rotate, and the irradiation unit 422 can perform proton beam irradiation therapy on the patient's lesion from multiple angles to ensure that the lesion receives uniform metered irradiation.

[0067] See also Figure 1 , Figure 4 , Figure 5 In one embodiment of the present invention, the positions of the detection module 320 and the proton therapy module 420 may be arranged in a variety of ways. For example, a first arrangement is that the detection module 320 is located on a side of the proton therapy module 420 close to the patient 600. A second arrangement is that the detection module 320 is located on a side of the proton therapy module 420 away from the patient 600. A third arrangement is that the detection module 320 and the proton therapy module 420 coincide with each other in the axial direction of the treatment cabin 110, that is, the isocenter of the detection module 320 and the isocenter of the proton therapy module 420 are located in the same radial plane of the treatment cabin 100. In proton therapy, the isocenter generally refers to the intersection of the rotation axes of the detection machine and the treatment machine. In this embodiment, the position deviation between the isocenter of the detection module 320 and the isocenter of the proton therapy module 420 is a fixed value, which can be measured in advance using a calibration model to obtain the deviation value between the isocenter of the detection module 320 and the isocenter of the proton therapy module 420, which can be expressed as isocenter deviation data V0 (x0, y0, z0, α0, β0, γ0) and stored in the control system.

[0068] See also Figure 2 , Figure 3 , Figure 5In one embodiment of the present invention, the proton therapy module 420 further includes an irradiation attachment 423. In the present invention, when the first and second arrangements are adopted, the irradiation attachment 423 can be fixedly connected to the treatment frame 410. The irradiation attachment 423 is aligned with the output port of the irradiation unit 422. When the third arrangement is adopted, it can be seen that when the detection module 320 and the proton therapy module 420 overlap in the axial direction of the treatment cabin 110, the treatment unit 400 is located outside the circumference of the detection assembly 300. Therefore, when the proton therapy module 420 performs irradiation therapy, the detection assembly 300 may block the proton beam output by the irradiation unit 422. In this embodiment, the irradiation attachment 423 can be fixedly connected to the detection frame 310. When the irradiation unit 422 performs irradiation therapy, first, the detection frame 310 rotates to the position where the irradiation attachment 423 is aligned with the irradiation unit 422; then, the treatment frame 410 and the detection frame 310 are locked to achieve synchronous rotation. At this time, the proton beam output by the irradiation unit 422 can pass through the irradiation attachment 423 and irradiate the patient's lesion, and will not be blocked by the detection module 320 at any angle. After the treatment is completed, the treatment frame 410 and the detection frame 310 are unlocked, and the two resume independent movement.

[0069] See also Figure 5 , Figure 6 In one embodiment of the present invention, the treatment bed 200 can also drive the patient 600 to rotate in the horizontal plane to adjust the position of the patient 600, so as to perform non-coplanar treatment. The treatment cabin 110 can be arranged in the horizontal direction, one end of which is an open end, which can be arranged on the side wall of the equipment body 100, and the patient 600 is transported to the treatment cabin through the open end, and the other end of which is arranged inside the equipment body 100 and is a closed end. The cross-sectional diameter of the closed end of the treatment cabin 110 is larger than the cross-sectional diameter of the open end, thereby expanding the rotation angle of the treatment bed 200 and better performing non-coplanar treatment. In this embodiment, the horizontal rotation angle of the treatment bed 200 in the treatment cabin 110 is not less than ±45°.

[0070] See also Figure 7 The present invention also provides a control method for a proton therapy device, which can be applied to the proton therapy device described in any of the above embodiments. The control method for a proton therapy device may include the following steps:

[0071] Step S100, moving the patient into the treatment cabin and acquiring CT image data of the patient's lesion;

[0072] Step S200, reconstructing the CT image data to generate a three-dimensional CT image of the patient's lesion;

[0073] Step S300, registering the patient's treatment plan image with the three-dimensional CT image to generate positioning deviation data, where the positioning deviation data represents the position deviation value between the patient's lesion and the preset treatment position;

[0074] Step S400: Based on the positioning deviation data, the patient is driven to move, and after the patient moves to the preset treatment position, proton beam irradiation therapy is performed on the patient's lesion.

[0075] In one embodiment of the present invention, when step S100 is executed, the patient is moved into the treatment cabin, and CT image data of the patient's lesion is collected. Specifically, after the patient enters the proton therapy room, the medical staff guides the patient to lie in an appropriate position on the treatment bed 200 and sets corresponding treatment parameters for the patient. The treatment parameters may include parameters such as the irradiation intensity, time, and angle of this treatment. In this embodiment, the treatment bed 200 rotates to be parallel to the axis of the treatment cabin 110, and then drives the patient to move to the isocenter position of the detection module 320. Then, the treatment bed 200 continues to drive the patient to move along the axis direction of the treatment cabin 110, and at the same time, the detection rack 310 drives the detection module 320 to rotate around the treatment cabin 110, thereby realizing spiral scanning imaging of the patient and generating continuous tomographic images of the patient. The continuous tomographic images of the patient can be saved as CT image data. During this process, the treatment rack 410 remains locked.

[0076] In one embodiment of the present invention, when step S200 is executed, the CT image data is reconstructed to generate a three-dimensional CT image of the patient's lesion. Specifically, after obtaining the CT scan data, the next step is to process the data and convert it into a three-dimensional image. In this embodiment, the processor 500 can reconstruct the CT image data to generate a three-dimensional CT image of the patient's lesion, that is, to combine two-dimensional CT slices to form a three-dimensional model, that is, a three-dimensional CT image, so as to more intuitively display the location and shape of the lesion.

[0077] In one embodiment of the present invention, when step S300 is executed, the treatment plan image of the patient is registered with the three-dimensional CT image to generate positioning deviation data, which represents the position deviation value between the patient's lesion and the preset treatment position. Specifically, first, the treatment plan image pre-planned by the doctor is obtained. The treatment plan image is created by the doctor or physicist in the radiotherapy planning system (TPS) based on the patient's CT, MRI (Magnetic Resonance Imaging) and other multimodal image data before treatment. These image data are used to outline the tumor (GTV) and other areas that may need treatment. Then, the treatment plan image is registered with the three-dimensional CT image. The registration process involves aligning the two sets of images so that they can be directly compared. Registration can be achieved by identifying the same anatomical markers in the two sets of images. For example, bone structures, skin markers, or internally implanted markers can be used as reference points for registration. After the image registration is completed, the processor 500 will automatically calculate the difference between the actual position of the patient's lesion and the planned position, which can be expressed as the positioning deviation data V1 (x1, y1, z1, α1, β1, γ1). The positioning deviation data reflects the difference between the actual position of the patient's lesion on the day of treatment and the ideal position specified in the treatment plan.

[0078] In one embodiment of the present invention, when step S400 is executed, the patient is moved based on the positioning deviation data, and after the patient moves to the preset treatment position, the patient's lesion is subjected to proton beam irradiation therapy. Specifically, after the positioning deviation data is determined, the treatment bed 200 will automatically adjust the patient's position according to these data so that the patient's lesion is accurately located at the preset treatment position. In this embodiment, based on the isocenter deviation data V0 (x0, y0, z0, α0, β0, γ0) and the positioning deviation data V1 (x1, y1, z1, α1, β1, γ1), the displacement V2 that the treatment bed 200 needs to adjust can be calculated. The displacement V2 can satisfy the following formula:

[0079] V2=V0+V1.

[0080] When the patient is accurately moved to the treatment position, the treatment component 400 starts to work and accurately irradiates the patient's lesion according to the preset irradiation intensity and time. This process is carried out while ensuring that the patient's position is correct to maximize the treatment effect and protect the surrounding healthy tissues.

[0081] Furthermore, after completing the radiation treatment at one angle, the treatment bed 200 can drive the patient to rotate according to the preset radiation angle to adjust the patient's position and achieve non-coplanar treatment. The above steps are repeated until the radiation treatment is completed according to all preset angles. At this time, the treatment bed 200 drives the patient to move out of the treatment cabin 110.

[0082] In summary, the present invention discloses a proton therapy device and a control method thereof. The present invention adopts a closed skin design for the treatment cabin, which avoids the risk of collision caused by the exposure of the mobile device. In addition, the fan beam CT used in the present invention can achieve diagnostic-level image accuracy, improve image guidance accuracy, and reduce positioning errors. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0083] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
