Description

Technical Field

[0001] The present invention relates to a beam shaping device.

Background Art

[0002] Boron Neutron Capture Therapy (BNCT) is a targeted heavy particle beam radiotherapy. A treatment device using this technology generates an ion beam by an accelerator, collides it with a target to generate a neutron source, and generates a high-performance neutron beam through functions such as collection, deceleration, and convergence of a Beam Shaping Assembly (BSA), thereby improving the treatment quality.

[0003] However, since the accelerator and its attached beam pipe require operation, maintenance, and repair, they need to be separated from the beam shaping assembly. And if there is not enough working space between them, the above measures cannot be taken. After the operation, maintenance, and repair are completed, both of them should be reset. Also, the accelerator and the beam shaping assembly both belong to heavy equipment and are not easy to align. Therefore, it is undoubtedly a very important issue in the industry how the user can easily and accurately perform effective position adjustment on the accelerator and the beam shaping assembly in a limited space.

Summary of the Invention

[0004] The object of the present invention is to provide a beam shaping device that can make good use of space, accurately adjust the position and horizontal height of the beam shaping assembly, and thereby accurately align it with the accelerator.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, a plurality of embodiments of the present invention will be disclosed in the drawings and, for the purpose of clear explanation, many actual details will be described in conjunction with the following description. However, it should be understood that these actual details should not be used to limit the present invention. That is, in some embodiments of the present invention, these actual details are not necessary. Furthermore, in order to simplify the drawings, some conventional structures and elements are simply illustrated in the drawings, but in all the drawings, the same reference numerals are used to represent the same or similar elements. Also, if possible, the features of different embodiments can be applied alternately.

[0024] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification have the general meaning that can be understood by those skilled in the art. Furthermore, the above terms are defined in commonly used dictionaries and should be interpreted as meanings consistent with the related fields of the present invention in the context of this specification. Unless specifically defined otherwise, these vocabulary words are not to be interpreted as idealized or overly formal meanings.

[0025] Referring to FIGS. 1 to 2, FIG. 1 is a schematic perspective view showing a beam shaping apparatus 100 according to an embodiment of the present invention. FIG. 2 is a side view showing the beam shaping apparatus 100 of FIG. 1. In the present embodiment, as shown in FIGS. 1 to 2, the beam shaping apparatus 100 includes a beam shaping assembly 110, a main support frame 130, a first auxiliary support frame 140, and a second auxiliary support frame 150. The beam shaping assembly 110 includes a front module 111 and a rear module 112. For the sake of simplicity of the drawing, in FIG. 1, the front module 111 and the rear module 112 of the beam shaping assembly 110 are all shown by dotted lines, and a working space WS is defined within the front module 111 and the rear module 112. The working space WS is configured to accommodate a neutron source 200 (for reference to FIG. 2. For the sake of simplicity of the drawing, the neutron source 200 is not shown in FIG. 1). The neutron source 200 is actually a target and is connected to an accelerator via a beam line pipe (the beam line pipe and the accelerator are not all shown). The beam is generated by the accelerator and collides with the neutron source 200 via the beam line pipe to generate neutrons. When the beam shaping apparatus 100 operates, the front module 111 and the rear module 112 are connected to and combined with each other (shown in FIG. 3). The beam shaping assembly 110 adjusts the energy spectrum of neutrons generated by the neutron source 200 by methods such as collection, deceleration, and convergence, thereby generating a high-performance neutron beam and enhancing the therapeutic effect of the beam shaping apparatus 100. Further, the main support frame 130 is configured to support the front module 111 and the rear module 112. The first auxiliary support frame 140 is detachably connected to the main support frame 130 and the front module 111 and is used to move the front module 111 relative to the main support frame 130. The second auxiliary support frame 150 is detachably connected to the main support frame 130 and the rear module 112 and is used to move the rear module 112 relative to the main support frame 130.

[0026] Specifically, as shown in FIGS. 1 to 2, the front module 111 and the rear module 112 are arranged along a first direction D1, and the first auxiliary support frame 140 and the second auxiliary support frame 150 are also detachably connected to opposite sides of the main support frame 130 along the first direction D1. Therefore, the front module 111 can move from the first auxiliary support frame 140 to the main support frame 130 or from the main support frame 130 to the first auxiliary support frame 140 along the first direction D1. Similarly, the rear module 112 can move from the second auxiliary support frame 150 to the main support frame 130 or from the main support frame 130 to the second auxiliary support frame 150 along the first direction D1. In this way, by detachably connecting the first auxiliary support frame 140 and the second auxiliary support frame 150 to opposite sides of the main support frame 130 along the first direction D1, the front module 111 and the rear module 112 are movable relative to the main support frame 130 so as to move away from or close to each other, and the environment where the beam shaping device 100 is located can make better use of space, thereby enabling the user to easily operate, repair, or maintain the accelerator and its attached beam line pipe. For example, the distance between the front module 111 and the rear module 112 can reach 200 centimeters.

[0027] Please refer to FIGS. 3 to 4. FIG. 3 is a schematic perspective view showing the beam shaping device 100 of FIGS. 1 to 2. The front module 111 and the rear module 112 are already placed on the main support frame 130, but the first auxiliary support frame 140 and the second auxiliary support frame 150 are all removed. FIG. 4 is an exploded schematic view showing the main support frame 130 of FIG. 3. For the sake of simplicity of the drawing, in FIG. 3, the front module 111 and the rear module 112 of the beam shaping assembly 110 are all shown by dotted lines, and the front module 111 and the rear module 112 are already close to and connected to each other. The already connected and combined beam shaping assembly 110 can adjust the energy spectrum of the neutrons generated by the neutron source 200, thereby generating a high-performance neutron beam. At this time, the first auxiliary support frame 140 and the second auxiliary support frame 150 (for the first auxiliary support frame 140 and the second auxiliary support frame 1500, please refer to FIGS. 1 to 2) no longer support the front module 111 and the rear module 112, so they can be removed, which is advantageous for space saving.

[0028] In this embodiment, as shown in FIGS. 3 to 4, the main support frame 130 includes a first support bracket 131, a plurality of first rails 132, a first regulating bracket 133, a plurality of anchor bases 134, and a plurality of first horizontal adjusters 135. The first rails 132 are provided on the first support bracket 131, and the front module 111 and the rear module 112 are respectively configured to be movably provided on the first rails 132. The first support bracket 131 is movably connected to the first regulating bracket 133, and the first regulating bracket 133 can actually be welded by a U-shaped groove. The anchor bases 134 are separated from each other and provided on the ground base 300 (for the ground base 300, please refer to FIGS. 1 to 2). The first horizontal adjusters 135 are respectively connected between a corresponding one of the anchor bases 134 and the first regulating bracket 133.

[0029] Further, as shown in FIGS. 3 to 4, the first rail 132 extends along the first direction D1 so that the front module 111 and the rear module 112 can move along the first direction D1 on the first rail 132 with respect to the first support bracket 131. Further, the first support bracket 131 is configured to move along the first direction D1 and the second direction D2 with respect to the first restricting bracket 133, and the second direction D2 is perpendicular to the first direction D1.

[0030] Specifically, as shown in FIGS. 3 to 4, the first restricting bracket 133 has a plurality of first screw holes H1 distributed on both opposite sides of the first restricting bracket 133 and each extending along the first direction D1. A user can use a plurality of first screws S1 to respectively couple to the corresponding first screw holes H1 and can press the first support bracket 131 with the first screws S1, thereby moving the first support bracket 131 along the first direction D1 with respect to the first restricting bracket 133, that is, accurately moving the front module 111 and the rear module 112 along the first direction D1 so as to accurately align them with the neutron source 200. For example, the moving range of the first support bracket 131 along the first direction D1 with respect to the first restricting bracket 133 is ±1 centimeter.

[0031] Similarly, as shown in FIGS. 3 to 4, the first restricting bracket 133 further has a plurality of second screw holes H2 distributed on both opposite sides of the first restricting bracket 133 and each extending along the second direction D2. A user can use a plurality of second screws S2 to respectively couple to the corresponding second screw holes H2 and can press the first support bracket 131 with the second screws S2, thereby moving the first support bracket 131 along the second direction D2 with respect to the first restricting bracket 133, that is, accurately moving the front module 111 and the rear module 112 along the second direction D2 so as to accurately align them with the neutron source 200.

[0032] Furthermore, as shown in FIGS. 3 to 4, each of the anchor bases 134 has a plurality of third screw holes H3 extending along the second direction D2. When the first regulation bracket 133 is fixed to the anchor base 134 in the second direction D2, the user can use a plurality of third screws S3 to couple them to the corresponding third screw holes H3 respectively, and press the first support bracket 131 with the third screws S3, thereby moving the first support bracket 131 along the second direction D2 with respect to the first regulation bracket 133, that is, accurately moving the front module 111 and the rear module 112 provided on the first support bracket 131 in the second direction D2, so that the front module 111 and the rear module 112 can be accurately positioned with respect to the neutron source 200, the front module 111 and the rear module 112 provided on the first support bracket 131 are accurately moved in the second direction D2. For example, the moving range of the first support bracket 131 along the second direction D2 with respect to the first regulation bracket 133 is ±1 cm.

[0033] However, the form of pushing the first support bracket 131 with screws so as to move it with respect to the first regulation bracket 133 mentioned above is only an example and is not used to limit the present invention. Those skilled in the art should understand that they should appropriately select the form of moving the first support bracket 131 with respect to the first regulation bracket 133 according to the actual situation.

[0034] Furthermore, the first horizontal adjuster 135 is configured to adjust the position of each corresponding one of the anchor bases 134 of the first regulating bracket 133 along the third direction D3, where the third direction D3 is perpendicular to the first direction D1 and the second direction D2. By adjusting the position of the first regulating bracket 133 in the third direction D3 relative to the corresponding anchor base 134 with an individual first horizontal adjuster 135, the user can easily and accurately reach the correct horizontal height in the third direction D3 for the front module 111 and the rear module 112 provided on the main support frame 130, so that the front module 111 and the rear module 112 can be accurately aligned with respect to the neutron source 200. For example, the movement range of the first regulating bracket 133 along the third direction D3 relative to the corresponding anchor base 134 is ±0.5 cm.

[0035] In this embodiment, the first rails 132 on the first support brackets 131 extend along the first direction D1 respectively. The corresponding first screw holes H1 coupled to the first screws S1 can be finely adjusted along the first direction D1. The corresponding second screw holes H2 coupled to the second screws S2 and the corresponding third screw holes H3 coupled to the third screws S3 can be finely adjusted in the direction along the second direction D2. The first horizontal adjuster 135 can finely adjust the position of the first regulating bracket 133 along the third direction D3 with respect to each corresponding one of the anchor bases 134. Although the first screw S1 coupled to the first screw hole H1 can be finely adjusted in the first direction D1, in order to avoid the mutual influence of this fine adjustment on the coupling between the second screw S2 and the second screw hole H2 and / or the coupling between the third screw S3 and the third screw hole H3, for the independent movement of different parts of the main support frame 130 in the first direction D1, the second direction D2, and the third direction D3, it is necessary to pass through the movement of the first rail 132 in the first direction D1.

[0036] As described above, the movement of the front module 111 and the rear module 112 provided on the main support frame 130 in the first direction D1, the second direction D2, and the third direction D3 is achieved by independent mechanisms. That is, the movement of the front module 111 and the rear module 112 in the first direction D1, the second direction D2, and the third direction D3 does not affect or interfere with each other. Therefore, the user can accurately adjust the positions and the horizontal heights of the front module 111 and the rear module 112, which is beneficial to improving the operating effect of the beam shaping device 100.

[0037] Please refer to FIG. 5. FIG. 5 is a schematic perspective view showing the first auxiliary support frame 140 of FIGS. 1 to 2. In the present embodiment, as shown in FIG. 5, the first auxiliary support frame 140 includes a second support bracket 141, a plurality of second rails 142, a second regulating bracket 143, a first base frame 144, a plurality of second horizontal adjusters 145, a first driving part 146, and a first moving part 147. The second support bracket 141 is detachably connected to the first support bracket 131 (please refer to FIGS. 1 to 2). The second rails 142 are provided on the second support bracket 141 and aligned with the first rails 132 (please refer to FIGS. 1 to 2). The second regulating bracket 143 supports and fixes the second support bracket 141. The first base frame 144 is detachably connected to at least one corresponding one of the anchor bases 134 (please refer to FIGS. 1 to 2). The second horizontal adjusters 145 are respectively connected between the first base frame 144 and the second regulating bracket 143 and are configured to move the second regulating bracket 143 relative to the first base frame 144 along the third direction D3, thereby adjusting the distance between the first base frame 144 and the second regulating bracket 143. The first driving part 146 is connected to the second support bracket 141. For example, in the present embodiment, the first driving part 146 is further detachably connected to the first support bracket 131. However, in other embodiments, according to the actual situation, the first driving part 146 and the first support bracket 131 are separated from each other, that is, the first driving part 146 and the first support bracket 131 are not connected to each other. The first moving part 147 is configured to be detachably connected to the front module 111 (please refer to FIGS. 1 to 2), and the first driving part 146 is connected to the first moving part 147 and configured to drive the movement of the first moving part 147.

[0038] Also, the first driving part 146 and the first moving part 147 are located between the second rails 142, that is, the second rails 142 are partitioned from each other, thereby providing more stable support for the front module 111.

[0039] More specifically, the first driving unit 146 includes a first connection member 1461, a first screw rod 1462, and at least one first guide rod 1463. As described above, for example, in the present embodiment, the first connection member 1461 is detachably connected to the first support bracket 131. However, in other embodiments, depending on the actual situation, the first connection member 1461 and the first support bracket 131 are separated from each other, that is, the first connection member 1461 and the first support bracket 131 are not connected to each other. The first screw rod 1462 is connected between the second support bracket 141 and the first connection member 1461, and the first screw rod 1462 is configured to rotate with respect to the second support bracket 141 and the first connection member 1461, and the first moving unit 147 is coupled to the first screw rod 1462. The first guide rod 1463 passes through the first moving unit 147 and is connected between the second support bracket 141 and the first connection member 1461. The first guide rod 1463, the first screw rod 1462, and the second rail 142 are parallel to each other and extend along the first direction D1 respectively. By rotating the first screw rod 1462 and receiving the restriction and guidance by the first guide rod 1463, the first moving unit 147 can move along the first guide rod 1463 and the first screw rod 1462, whereby the first moving unit 147 is movably connected to the front module 111 in the first direction D1.

[0040] Please refer to FIG. 6. FIG. 6 is a schematic perspective view showing the second auxiliary support frame 150 of FIGS. 1 to 2. In the present embodiment, as shown in FIG. 6, the second auxiliary support frame 150 includes a third support bracket 151, a plurality of third rails 152, a third regulating bracket 153, a second base frame 154, a plurality of third level adjusters 155, a second drive unit 156, and a second moving unit 157. The third support bracket 151 is detachably connected to the first support bracket 131 (please refer to FIGS. 1 to 2). The third rail 152 is provided on the third support bracket 151 and aligned with the first rail 132 (please refer to FIGS. 1 to 2). The third regulating bracket 153 supports and fixes the third support bracket 151. The second base frame 154 is detachably connected to at least the corresponding other one of the anchor bases 134 (please refer to FIGS. 1 to 2). The third level adjusters 155 are respectively connected between the second base frame 154 and the third regulating bracket 153 and are configured to move the third regulating bracket 153 relative to the second base frame 154 along the third direction D3, thereby adjusting the distance between the second base frame 154 and the third regulating bracket 153. The second drive unit 156 is connected to the third support bracket 151. For example, in the present embodiment, the second drive unit 156 is further detachably connected to the first support bracket 131. However, in other embodiments, according to the actual situation, the second drive unit 156 and the first support bracket 131 are separated from each other, that is, the second drive unit 156 and the first support bracket 131 are not connected to each other. The second moving unit 157 is configured to be detachably connected to the rear module 112 (please refer to FIGS. 1 to 2), and the second drive unit 156 is connected to the second moving unit 157 and configured to drive the movement of the second moving unit 157.

[0041] Also, the second drive unit 156 and the second moving unit 157 are located between the third rails 152, that is, the third rails 152 are partitioned from each other, thereby providing stable support for the rear module 112.

[0042] More specifically, the second driving unit 156 includes a second connecting member 1561, a second threaded rod 1562, and at least one second guide rod 1563. As described above, for example, in the present embodiment, the second connecting member 1561 is detachably connected to the first support bracket 131. However, in other embodiments, according to the actual situation, the second connecting member 1561 and the first support bracket 131 are separated from each other, that is, the second connecting member 1561 and the first support bracket 131 are not connected to each other. The second threaded rod 1562 is connected between the third support bracket 151 and the second connecting member 1561. The second threaded rod 1562 is configured to rotate with respect to the third support bracket 151 and the second connecting member 1561. The second moving unit 157 is coupled to the second threaded rod 1562. The second guide rod 1563 passes through the second moving unit 157 and is connected between the third support bracket 151 and the second connecting member 1561. The second guide rod 1563, the second threaded rod 1562, and the third rail 152 are parallel to each other and each extend along the first direction D1. By rotating the second threaded rod 1562 and receiving the restriction and guidance by the second guide rod 1563, the second moving unit 157 can move along the second guide rod 1563 and the second threaded rod 1562, whereby the second moving unit 157 is movably connected to the rear module 112 in the first direction D1.

[0043] Furthermore, as shown in FIG. 5, the first threaded rod 1462 has a first length L1, and as shown in FIG. 6, the second threaded rod 1562 has a second length L2. In actual applications, the first length L1 and the second length L2 are different, that is, the maximum stroke of the first moving unit 147 is different from the maximum stroke of the second moving unit 157. In this way, the moving widths of the front module 111 and the rear module 112 in the first direction D1 can be different, thereby enhancing the flexibility of use of the beam shaping device 100. For example, according to the actual situation, the second length L2 may be greater than the first length L1, that is, the moving width of the rear module 112 in the first direction D1 may be greater than the moving width of the front module 111 in the first direction D1.

[0044] As described above, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages.

[0045] (1) By detachably connecting the first auxiliary support frame and the second auxiliary support frame to the opposite sides of the main support frame along the first direction, the front module and the rear module can move relative to the main support frame respectively, and can be separated from each other or approach each other, so that the environmental space where the beam shaping device is located can be better utilized, thereby enabling the user to easily operate, repair or maintain the accelerator and its attached beam line pipe. And when the first auxiliary support frame and the second auxiliary support frame no longer support the front module and the rear module, they can be removed, which is advantageous for space saving.

[0046] (2) The movement of the front module and the rear module provided on the main support frame in the first direction, the second direction and the third direction is achieved by independent mechanisms, that is, the movement of the front module and the rear module in the first direction, the second direction and the third direction does not affect or interfere with each other. Therefore, the user can accurately adjust the position and horizontal height of the front module and the rear module, which is advantageous for improving the operating effect of the beam shaping device.

[0047] (3) Since the maximum stroke of the first moving part is different from the maximum stroke of the second moving part, the moving widths of the front module and the rear module in the first direction can be different, thereby enhancing the flexibility of use of the beam shaping device.

[0048] Although the present invention is disclosed in the above embodiments as described above, the above embodiments are not used to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be based on what is limited by the patent scope of the application attached later.
