Description
Technical Field
[0001] This utility model relates to the field of radiotherapy equipment technology, specifically to a dual-ring non-coplanar radiation irradiation device. Background Technology
[0002] Radiation therapy is an important treatment for cancer, using radiation to kill tumor cells. However, it inevitably damages normal tissue cells along the path of the radiation. Therefore, it is crucial to select an optimal angle of radiation incidence during radiation therapy to ensure the tumor receives the correct dose while minimizing damage to normal tissues or organs. Consequently, a wide range of radiation angles is a key indicator of the effectiveness of radiation therapy.
[0003] Existing radiotherapy equipment typically uses a rotating gantry to rotate the treatment head around the patient's body. The selectable incident angles of the radiation are distributed within the plane of rotation of the gantry, known as coplanar irradiation. If the treatment bed is also rotated, the selectable incident angles are distributed in three-dimensional space, known as non-coplanar irradiation. Obviously, the range of radiation angles for non-coplanar irradiation is much larger than that for coplanar irradiation. However, existing radiotherapy equipment has the following problems when performing non-coplanar irradiation: 1. After rotating the bed, the treatment head and the patient or treatment bed will collide at most rotation angles of the gantry, resulting in a small range of practically applicable non-coplanar irradiation angles; 2. Rotating the treatment bed requires a professional to enter the treatment room from the control room and walk to the treatment bed to operate, which significantly prolongs the patient's treatment time each time; 3. When the professional rotates the treatment bed, the patient's body is prone to swaying on the bed surface, which can cause changes in the treatment position and affect treatment accuracy; 4. To ensure treatment accuracy, the treatment position needs to be re-verified after each rotation of the treatment bed, but existing radiotherapy equipment lacks suitable verification tools. To overcome these problems with existing radiotherapy equipment, researchers have designed various non-coplanar radiation irradiation devices. For example, patent application number 201110447735.5 discloses a 4D stereotactic radiotherapy device, which allows the radiation therapy head to follow the gantry in nodding and tilting movements, thereby achieving three-dimensional adjustment of the radiation angle and providing greater support for precise detection and non-coplanar treatment. However, collision problems still exist between the rotating gantry and the treatment bed, and the achievable stereotactic irradiation range is small. Patent application number 201410558872.X... The application discloses a five-degree-of-freedom O-arm radiotherapy system, which achieves five-degree-of-freedom control of the radiotherapy process with high control precision and stability, but the overall structure is complex and the achievable solid angle range is relatively small. The invention patent application with application number 201810078431.8 discloses a cage-type radiotherapy device, which can achieve rapid and accurate non-coplanar irradiation with a large solid angle range without moving the patient through the multi-degree-of-freedom movement of the radiation generating mechanism. However, the treatment space is relatively long and the spatial pressure is strong, which is not conducive to the treatment of patients with claustrophobia and is inconvenient for patient positioning.

[0038] like Figures 1 to 8 As shown, the dual-ring non-coplanar X-ray irradiation device provided in this embodiment includes a treatment bed 1, a first annular support 2 and a second annular support 3 arranged parallel to each other at one end of the treatment bed 1; rotating rings 4 are rotatably provided on the first annular support 2 and the second annular support 3, the two rotating rings 4 are vertically parallel and coaxially arranged (i.e. have the same axis of rotation), and a rotation drive mechanism for driving the rotating rings 4 is provided on the first annular support 2 and / or the second annular support 3; a first arc-shaped slide 5 and a second arc-shaped slide 6 are connected between the two rotating rings 4, and the first arc-shaped slide 5 and the second arc-shaped slide 6 have the same curvature; radiation-related components are rotatably provided on the first arc-shaped slide 5 and the second arc-shaped slide 6; two opposing connecting beams 7 are also connected between the two rotating rings 4, and imaging components are slidably provided on the connecting beams 7. The first arc-shaped carriage 5 includes an upper arc-shaped beam 10 with its two ends respectively connected to the two rotating rings 4, and each upper arc-shaped beam 10 is connected to a lower arc-shaped beam 11 with the same arc as the upper arc-shaped beam 10; the two upper arc-shaped beams 10 are provided with a first mounting bracket 12 that slides along the upper arc-shaped beam 10.
[0039] Specifically, one end of the first mounting bracket 12 is equipped with the radiator head 13 of the radiation-related component, and a first driving device 14 is provided on one side of the first mounting bracket 12; a first arc-shaped rack 15 is provided on one of the lower arc-shaped beams 11, and the first driving device 14 is connected to a first driving gear that meshes with the first arc-shaped rack 15; a first arc-shaped first slide groove 17 matching the other lower arc-shaped beam 11 is provided on one side of the first mounting bracket 12. The second arc-shaped slide 6 includes support legs 18 respectively connected to the two rotating rings 4; two arc-shaped slide rails 19 with the same curvature as the upper arc-shaped beam 10 are connected to the support legs 18.
[0040] A second mounting bracket 20 is slidably disposed between the two arc-shaped slide rails 19. The second mounting bracket 20 has a second slide groove 21 that matches the arc-shaped slide rail 19. One of the arc-shaped slide rails 19 has a second arc-shaped rack 22. A second driving device 23 is connected to one side of the second mounting bracket 20. The second driving device 23 is connected to a second driving gear that meshes with the second arc-shaped rack 22. The second mounting bracket 20 has a beam deflector 24 corresponding to the radiation head 13. The beam deflector 24 has a radiation detector 25.
[0041] In this embodiment, the rotary drive mechanism includes an actuator disposed on one side of the first annular support 2 and / or the second annular support 3, and the actuator drives the rotating ring 4. The driving connection between the actuator and the rotating ring 4 can be, but is not limited to, gear transmission, worm gear transmission, belt transmission, or chain transmission. The actuator can be, but is not limited to, a motor, hydraulic pump, or pneumatic pump. Correspondingly, gears, synchronous pulleys, or sprockets that cooperate with the rotary drive mechanism are disposed on the rotating ring. For example, if the actuator is a rotary drive motor 29 disposed on one side of the first annular support 2 and / or the second annular support 3, and the rotary drive motor 29 is connected to a rotary gear, then a driven gear 30 that meshes with the rotary gear is connected to the axial end face of one or both rotating rings 4.
[0042] Combination Figure 1 , Figure 2 As shown, the first arc-shaped carriage 5 is horizontally arranged between the two rotating rings 4, the radiator head 13 is slidably arranged on the first arc-shaped carriage 5, the second arc-shaped carriage 6 is horizontally arranged between the two rotating rings 4 opposite to the first arc-shaped carriage 5, the beam block assembly is slidably arranged on the second arc-shaped carriage 6, the two connecting beams 7 are horizontally arranged between the two rotating rings 4 opposite to each other, the two connecting beams 7 are orthogonal to the first arc-shaped carriage 5 and the second arc-shaped carriage 6, and the imaging assembly is slidably arranged on the connecting beams 7.
[0043] like Figure 5 As shown, the first arc-shaped slide 5 is a frame structure with a central space for the arc-shaped sliding of the radiating head. One end of the first arc-shaped slide 5 is fixedly mounted on a rotating ring, and the other end is fixedly mounted on another rotating ring. The first arc-shaped slide has one or a pair of first arc-shaped slide rails (i.e., one or a pair of upper arc-shaped beams). Correspondingly, a lower arc-shaped beam is arranged below the upper arc-shaped beam, and the lower arc-shaped beam has an arc-shaped rack (i.e., a first arc-shaped rack) for arc-shaped sliding. The radiating head is slidably mounted on the first arc-shaped slide 5 via a first mounting bracket, as shown... Figure 6 As shown, the first mounting frame has arc-shaped sliding grooves on both sides that slide in conjunction with the upper arc-shaped beam of the first arc-shaped slide. The trajectory of the radiating head sliding along the first arc-shaped slide is an arc-shaped trajectory, and the central axis of the arc is perpendicular to the rotation axis of the rotating ring.
[0044] like Figure 7As shown, the second arc-shaped carriage is also a frame structure. On the inner side of each of the two rotating rings, there are two supporting legs. An arc-shaped slide rail connects the two supporting legs of different rotating rings. Correspondingly, a second arc-shaped rack for the arc-shaped sliding of the baffle is provided in the arc-shaped slide rail arrangement direction. The central axis of the arc of the second arc-shaped carriage is coaxial with the axis of the first arc-shaped carriage. After the radiating head slides along the first arc-shaped carriage at a certain angle, the baffle follows the radiating head and slides along the second arc-shaped carriage in the opposite direction at the same angle, so that the radiating head and the baffle are always facing each other.
[0045] The retainer is slidably mounted on the arc-shaped slide rail of the second arc-shaped carriage via the second mounting bracket, such as... Figure 8 As shown, the bottom of the second mounting bracket is fixedly provided with one or a pair of arc-shaped second sliding grooves that slide in cooperation with the arc-shaped slide rail. The beam deflector 24 is provided with a radiation detector 25, which is an MV-class X-ray detector. The second mounting bracket is provided with a second driving device, which is connected to a main gear. The main gear meshes with a second arc-shaped rack on the arc-shaped slide rail. Both the first driving device and the second driving device can be servo motors.
[0046] In this embodiment, the imaging component can be an X-ray imaging component or a magnetic resonance imaging component.
[0047] When using an X-ray imaging assembly, it includes an X-ray tube 9 and an X-ray detector plate 8. The X-ray tube is mounted on one of the connecting beams 7, and the X-ray detector plate is mounted opposite the X-ray tube on the other connecting beam. The X-ray imaging assembly can be either cone-beam imaging or fan-beam imaging. In cone-beam imaging, the X-ray tube and X-ray detector are slidably mounted on the two connecting beams via a moving assembly. Before imaging, the distance between the X-ray tube and the X-ray detector, and their relative imaging location to the patient, are adjusted using the moving assembly. Then, with the moving assembly stationary, the X-ray imaging assembly rotates around its axis under the rotation of the rotating ring to complete cone-beam imaging of the patient. The moving assembly can be a robotic arm, a multi-degree-of-freedom slide, or, for example, a linear servo drive module. In fan-beam imaging, the patient remains stationary. The moving assembly moves the X-ray imaging assembly along the axis of the sliding ring while the X-ray imaging assembly rotates under the rotation of the rotating ring, achieving fan-beam helical tomography imaging of the patient.
[0048] When the imaging component is magnetic resonance imaging, the magnetic resonance imaging component includes two magnets mounted opposite each other. The magnets can be, but are not limited to, circular, annular, or racetrack-shaped.
[0049] like Figure 3The diagram shown illustrates the patient's pre-treatment positioning for this invention. The patient lies supine on the flat surface of the treatment bed. An external laser light is aligned with the marking lines on the patient's body surface to complete the initial positioning. The flat surface can move with multiple degrees of freedom relative to the base of the treatment bed, such as three-dimensional translation and three-dimensional rotation. By moving the flat surface, the patient is moved to the treatment position. The imaging component images the patient, and the positioning error is obtained through image analysis. Moving the flat surface corrects the positioning error, ensuring that the patient's treatment center coincides with the isocenter, thus completing the positioning error correction and finalizing the patient's positioning. Figure 4 As shown, after the patient is positioned, the rotating ring is driven by the rotation drive mechanism to rotate relative to the first and second ring supports to the angle set in the radiotherapy plan. The radiation head slides along the first arc-shaped slide to the non-coplanar irradiation angle set in the radiotherapy plan to irradiate the patient.
[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that, based on the technical solutions disclosed in the present utility model, all modifications or variations that can be made by those skilled in the art without creative effort should be included within the scope of protection of the present utility model.
