專利文獻1：日本特開2007-289373號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2007-289373

搭載半導體的電子設備抗輻射能力較差，若在存在放 射線的環境下使用，則有可能發生故障。若在治療台的內部或治療台的附近設有搭載半導體的控制手段，則有可能使控制手段發生故障。與其他放射線治療相比，當進行中子束捕捉療法時，照射室內部的放射線量尤其變高，因此對於搭載半導體的電子設備的影響較大。專利文獻1中所記載的技術中，將搭載半導體的控制手段設置在治療台時，有可能使控制手段發生故障。 Semiconductors equipped with semiconductors have poor radiation resistance, if they are present When used in a ray environment, malfunction may occur. If a semiconductor-mounted control means is provided inside the treatment table or in the vicinity of the treatment table, the control means may malfunction. Compared with other radiation treatments, when the neutron beam capturing therapy is performed, the amount of radiation inside the irradiation chamber is particularly high, and thus the influence on the electronic device on which the semiconductor is mounted is large. In the technique described in Patent Document 1, when the control means for mounting the semiconductor is placed in the treatment table, the control means may be broken.

本發明的目的在於，提供一種能夠減少搭載半導體的控制部發生故障的可能性且提高可靠性的中子束捕捉療法系統。 An object of the present invention is to provide a neutron beam capturing therapy system capable of reducing the possibility of failure of a control unit on which a semiconductor is mounted and improving reliability.

本發明的中子束捕捉療法系統具備：照射室，進行對被照射體的中子束的照射；照射部，向照射室的內部照射中子束；治療台，可在照射室的內部與照射室的外部之間移動；控制部，配置於照射室的外部，且具有半導體元件，並控制治療台的動作；及發送電纜，與治療台連接，並傳遞控制部與治療台之間的訊號。 The neutron beam capturing therapy system of the present invention includes: an irradiation chamber that irradiates a neutron beam to the irradiated body; an irradiation unit that irradiates the inside of the irradiation chamber with a neutron beam; and a treatment table that can be irradiated inside the irradiation chamber The control unit is disposed outside the irradiation chamber and has a semiconductor element and controls the operation of the treatment table. The transmission cable is connected to the treatment station and transmits a signal between the control unit and the treatment unit.

該中子束捕捉療法系統中，在照射室的外部配置有控制部，能夠利用發送電纜將從該控制部輸出的訊號傳遞到治療台，因此無需在治療台上設置控制部。因此，不用隨著治療台的移動而在照射室的內部配置控制部，因此因放射線而引起的控制部發生故障的可能性減少。並且，由於在治療台上連接有發送電纜，因此無需在照射室的內部進 行將發送電纜連接到治療台的工作。藉此，照射室內部中的工作減少，由此能夠減少工作人員的輻射暴露量。並且，無需在照射室的內部設置用於連接治療台與發送電纜的設備，因此無需進行該連接用設備的維護。因此，工作人員無需為了維護而進入照射室的內部，且能夠減少工作人員的輻射暴露量。 In the neutron beam capturing therapy system, a control unit is disposed outside the irradiation room, and the signal output from the control unit can be transmitted to the treatment station by the transmission cable. Therefore, it is not necessary to provide a control unit on the treatment table. Therefore, since the control unit is not disposed inside the irradiation chamber as the treatment table moves, the possibility that the control unit is broken due to the radiation is reduced. Moreover, since the transmission cable is connected to the treatment table, there is no need to enter the inside of the irradiation room. The line will connect the sending cable to the treatment station. Thereby, the work in the interior of the irradiation room is reduced, whereby the radiation exposure amount of the worker can be reduced. Further, since it is not necessary to provide a device for connecting the treatment table and the transmission cable inside the irradiation chamber, maintenance of the connection device is not required. Therefore, the worker does not need to enter the interior of the irradiation room for maintenance, and can reduce the radiation exposure of the worker.

並且，中子束捕捉療法系統具備：凹槽部，設置於供治療台移動的地面，且在照射室的內部與照射室的外部之間連續；及長條狀的蓋部，配置在向凹槽部延伸的方向，且覆蓋凹槽部，並具有可撓性，發送電纜配置於凹槽部內，治療台具有隨著治療台的移動抬起蓋部的抬起部。依該結構的中子束捕捉療法系統，在治療台所移動的地面設有在照射室的內部與照射室的外部之間連續的凹槽部，且在該凹槽部內配置有發送電纜，因此能夠在治療台所移動的地面的下方收容發送電纜。藉此，能夠在不妨礙治療台的移動的位置配置發送電纜。並且，凹槽部被蓋部所覆蓋，因此凹槽部不會在地面露出，因此有人被該凹槽部絆倒的可能性減少。藉此，能夠提高安全性。並且，治療台的結構係具有隨著治療台的移動而抬起蓋部的抬起部，因此藉由將蓋部抬至高於地面，由此能夠將配置於凹槽部內的發送電纜從凹槽部內向外部導出。藉此，能夠在凹槽部內配置與治療台連接的發送電纜，以利用蓋部覆蓋凹槽部，並且隨著治療台的移動抬起蓋部，以將凹槽部內的發送電纜拉出到地面的上方，由此連接到治療台。 Further, the neutron beam capturing therapy system includes a groove portion that is provided on a floor on which the treatment table moves, and that is continuous between the inside of the irradiation chamber and the outside of the irradiation chamber, and an elongated cover portion that is disposed in the concave shape. The groove portion extends in a direction and covers the groove portion and has flexibility. The transmission cable is disposed in the groove portion, and the treatment table has a lifting portion that lifts the lid portion as the treatment table moves. According to the neutron beam capturing therapy system of this configuration, a groove portion continuous between the inside of the irradiation chamber and the outside of the irradiation chamber is provided on the ground on which the treatment table is moved, and a transmission cable is disposed in the groove portion, so that The transmission cable is housed below the floor on which the treatment table is moved. Thereby, the transmission cable can be placed at a position that does not interfere with the movement of the treatment table. Further, since the groove portion is covered by the lid portion, the groove portion is not exposed on the ground, and thus the possibility that a person is tripped by the groove portion is reduced. Thereby, safety can be improved. Further, the structure of the treatment table has a lifting portion that lifts the lid portion as the treatment table moves, so that the lifting portion disposed in the groove portion can be removed from the groove by lifting the lid portion above the ground. The inside is exported to the outside. Thereby, a transmission cable connected to the treatment table can be disposed in the groove portion to cover the groove portion with the cover portion, and the cover portion is lifted as the treatment table moves to pull the transmission cable in the groove portion to the ground. Above, thereby connecting to the treatment table.

並且，治療台具有：載置部，用於載置被照射體；行走台車，可在地面上行走；及支撐台，在行走台車上支撐載置部，抬起部可以設置於行走台車的內部。由於抬起部設置於治療台的行走台車的內部，因此能夠在行走台車的內部抬起蓋部來將凹槽部內的發送電纜導出到凹槽部的外部以連接到治療台。並且，在被行走台車覆蓋的區域內抬起蓋部，因此蓋部在被行走台車覆蓋的區域之外不會被抬起，其結果，在可供人移動的範圍內，能夠與地面平整地配置蓋部，且能夠減少有人被絆倒的可能性。 Further, the treatment table has a placing portion for placing the object to be irradiated, a traveling trolley for walking on the ground, and a support table for supporting the placing portion on the traveling trolley, and the lifting portion can be provided inside the traveling trolley . Since the lifting portion is provided inside the traveling trolley of the treatment table, the cover portion can be lifted inside the traveling trolley to guide the transmission cable in the groove portion to the outside of the groove portion to be connected to the treatment table. Further, since the lid portion is lifted in the area covered by the traveling bogie, the lid portion is not lifted outside the area covered by the traveling bogie, and as a result, it can be leveled with the ground in a range in which the person can move. The cover is configured and the possibility of someone being tripped can be reduced.

並且，中子束捕捉療法系統的結構可以如下：治療台具備向上方拉出發送電纜以導入到行走台車內的引導部，引導部配置於行走台車的內部。藉此，能夠藉由引導部引導配置於凹槽部內的發送電纜而拉至上方，由此改變發送電纜所延伸的方向，而適當地導入到行走台車的內部。並且，引導部收容於行走台車的內部，因此，能夠在不妨礙人們的工作和通行的位置配置引導部。 Further, the neutron beam capturing therapy system may have a configuration in which the treatment table includes a guide portion that pulls the transmission cable upward to be introduced into the traveling vehicle, and the guide portion is disposed inside the traveling vehicle. Thereby, the guide portion can guide the transmission cable disposed in the groove portion to be pulled upward, thereby changing the direction in which the transmission cable extends, and appropriately introducing it into the inside of the traveling vehicle. Further, since the guide portion is housed inside the traveling vehicle, the guide portion can be disposed at a position that does not hinder the work and travel of the person.

並且，中子束捕捉療法系統具備：屏蔽門，可閉合治療台所通過的照射室的出入口，且屏蔽放射線；及屏蔽塊，可在照射室的出入口的下方閉合凹槽部，且屏蔽放射線。依該結構的中子束捕捉療法系統，藉由屏蔽門閉合照射室的出入口，並藉由屏蔽塊閉合凹槽部，由此能夠藉由屏蔽放射線來抑制放射線透射到照射室的外部。 Further, the neutron beam capturing therapy system includes: a shielding door that closes an entrance and exit of the irradiation chamber through which the treatment table passes, and shields the radiation; and a shielding block that closes the groove portion below the entrance and exit of the irradiation chamber and shields the radiation. According to the neutron beam capturing therapy system of this configuration, the entrance and exit of the irradiation chamber are closed by the screen door, and the groove portion is closed by the shield block, whereby the radiation can be suppressed from being transmitted to the outside of the irradiation chamber by shielding the radiation.

並且，中子束捕捉療法系統的結構可以如下：作為發送電纜的固定端之一端側固定於控制部，作為發送電纜的 移動端之另一端側固定於治療台，凹槽部的內部設有將作為發送電纜的一端側與另一端側之間的部份亦即中間部份固定於凹槽部的中間固定部，中間固定部配置於照射室的外部。藉此，能夠固定發送電纜的位置，因此可防止發送電纜的位置隨著治療台的移動而大幅偏移或混亂。並且，能夠容易將發送電纜折回以收容於凹槽部內。例如，在治療台配置在距照射室最遠的位置的狀態下，能夠在中間固定部折回發送電纜而配置。並且，中間固定部配置於照射室的外部，因此在治療台配置在距照射室最遠的位置(例如準備室)的狀態下，能夠將發送電纜的折回位置配置在照射室的外部。因此能夠在與照射室的出入口對應的位置，不在凹槽部配置發送電纜，而是藉由在該位置配置屏蔽塊來閉合。 Further, the structure of the neutron beam capturing therapy system may be as follows: one end side of the fixed end of the transmission cable is fixed to the control unit as a transmission cable. The other end side of the moving end is fixed to the treatment table, and the inside of the groove portion is provided with an intermediate fixing portion that fixes a portion between the one end side and the other end side of the transmission cable, that is, the intermediate portion, to the groove portion. The fixing portion is disposed outside the irradiation chamber. Thereby, the position of the transmission cable can be fixed, so that the position of the transmission cable can be prevented from being largely shifted or confused with the movement of the treatment table. Further, the transmission cable can be easily folded back to be housed in the groove portion. For example, in a state where the treatment table is disposed at the position farthest from the irradiation chamber, the transmission cable can be folded back and disposed in the intermediate fixing portion. Further, since the intermediate fixing portion is disposed outside the irradiation chamber, the folded position of the transmission cable can be disposed outside the irradiation chamber in a state where the treatment table is disposed at the position farthest from the irradiation chamber (for example, the preparation chamber). Therefore, the transmission cable can be disposed not at the groove portion at a position corresponding to the entrance and exit of the irradiation chamber, but can be closed by arranging the shield block at the position.

並且，中子束捕捉療法系統具備：電力供給部，配置於照射室的外部，具有半導體元件並供給電力；及供電電纜，與治療台連接，並在電力供給部與治療台之間輸送電力，同時配置供電電纜與發送電纜。依這種結構的中子束捕捉療法系統，能夠將與治療台連接的供電電纜與發送電纜一起進行配線，並向治療台供給電力。並且，能夠藉由在照射室的外部配置電力供給部，以利用供電電纜將從電力供給部輸出的電力供給到治療台。因此，無需在治療台設置電力供給部。亦即，不用隨著治療台的移動而在照射室的內部配置電力供給部，因此電力供給部因放射線而發生故障的可能性減少。 Further, the neutron beam capturing therapy system includes a power supply unit that is disposed outside the irradiation chamber, has a semiconductor element and supplies electric power, and a power supply cable that is connected to the treatment station and that supplies power between the power supply unit and the treatment station. Configure the power cable and the sending cable at the same time. According to the neutron beam capturing therapy system having such a configuration, the power supply cable connected to the treatment table can be wired together with the transmission cable, and electric power can be supplied to the treatment table. Further, the power supply unit can be disposed outside the irradiation chamber, and the power output from the power supply unit can be supplied to the treatment station by the power supply cable. Therefore, it is not necessary to provide a power supply unit at the treatment station. That is, since the power supply unit is not disposed inside the irradiation chamber as the treatment table moves, the possibility that the power supply unit is broken by the radiation is reduced.

並且，本發明的中子束捕捉療法系統具備：照射室，進行對被照射體的中子束的照射；照射部，向照射室的內部照射中子束；治療台，可在照射室的內部與照射室的外部之間移動；電力供給部，配置於照射室的外部，且具有半導體元件並供給電力；及供電電纜，與治療台連接，並在電力供給部與治療台之間輸送電力。 Further, the neutron beam capturing therapy system of the present invention includes: an irradiation chamber that irradiates a neutron beam to the irradiated body; an irradiation unit that irradiates the inside of the irradiation chamber with a neutron beam; and a treatment table that can be inside the irradiation chamber The electric power supply unit is disposed outside the irradiation chamber and has a semiconductor element and supplies electric power. The power supply cable is connected to the treatment station and transmits electric power between the electric power supply unit and the treatment unit.

該中子束捕捉療法系統中，在照射室的外部配置有電力供給部，且能夠利用供電電纜將從該電力供給部輸出的電力傳遞至治療台，因此無需在治療台設置電力供給部。因此，不用隨著治療台的移動而在照射室的內部配置電力供給部，因此電力供給部因放射線而發生故障的可能性減少。並且，在治療台連接有供電電纜，因此無需在照射室的內部進行將供電電纜連接到治療台的工作，藉由減少在照射室的內部進行的工作，能夠減少工作人員的輻射暴露量。並且，無需在照射室的內部設置用於連接治療台與供電電纜的設備，因此無需進行該連接用設備的維護。因此，工作人員無需為了維護而進入照射室的內部，且能夠減少工作人員的輻射暴露量。 In the neutron beam capturing therapy system, the power supply unit is disposed outside the irradiation chamber, and the power output from the power supply unit can be transmitted to the treatment station by the power supply cable. Therefore, it is not necessary to provide the power supply unit at the treatment station. Therefore, since the power supply unit is not disposed inside the irradiation chamber as the treatment table moves, the possibility that the power supply unit is broken by the radiation is reduced. Further, since the power supply cable is connected to the treatment table, it is not necessary to perform the operation of connecting the power supply cable to the treatment table inside the irradiation chamber, and by reducing the work performed inside the irradiation chamber, the radiation exposure of the worker can be reduced. Further, since it is not necessary to provide a device for connecting the treatment table and the power supply cable inside the irradiation chamber, maintenance of the connection device is not required. Therefore, the worker does not need to enter the interior of the irradiation room for maintenance, and can reduce the radiation exposure of the worker.

The neutron beam output unit 8A is provided in the rear stage of the second transfer unit 12A, and the neutron beam output unit 8B is provided in the subsequent stage of the third transfer unit 12B.

並且，射束方向切換器11能夠使帶電粒子束P從正規軌道偏離並引導至射束收集器(未圖示)。射束收集器在進行治療之前確認帶電粒子束P的輸出時使用。另外，中子束捕捉療法系統1亦可以係不具備射束收集器的結構。 Further, the beam direction switcher 11 can deflect the charged particle beam P from the normal track and guide it to a beam collector (not shown). The beam collector is used to confirm the output of the charged particle beam P before performing the treatment. In addition, the neutron beam capturing therapy system 1 may be configured without a beam collector.

第1傳輸部10、第2傳輸部12A及第3傳輸部12B 各自包括用於帶電粒子束P的射束調整部13。射束調整部13包括帶電粒子束P的軸調整用水平型轉向器及水平垂直型轉向器、用於抑制帶電粒子束P的發散的四極電磁鐵以及用於帶電粒子束P的整形的四向裂縫等。亦可以構成為第1傳輸部10、第2傳輸部12A及第3傳輸部12B各自不具備射束調整部13。 First transmission unit 10, second transmission unit 12A, and third transmission unit 12B Each includes a beam adjustment portion 13 for the charged particle beam P. The beam adjustment unit 13 includes a horizontal steering type steering wheel and a horizontal vertical type steering gear for adjusting the charged particle beam P, a quadrupole electromagnet for suppressing the divergence of the charged particle beam P, and a four-direction for shaping the charged particle beam P. Cracks, etc. The first transmission unit 10, the second transmission unit 12A, and the third transmission unit 12B may not be provided with the beam adjustment unit 13.

第2傳輸部12A及第3傳輸部12B可以根據需要包括電流監視器。電流監視器即時測定照射到中子束輸出部8A、8B的帶電粒子束P的電流值(亦即，電荷、照射劑量率)。第2傳輸部12A及第3傳輸部12B可以根據需要包括帶電粒子束掃描部14(參閱第4圖)。帶電粒子束掃描部14掃描帶電粒子束P，並進行對靶T(參閱第4圖)的帶電粒子束P的照射控制。帶電粒子束掃描部14例如控制帶電粒子束P對靶T的照射位置。 The second transmission unit 12A and the third transmission unit 12B may include a current monitor as needed. The current monitor instantaneously measures the current value (i.e., charge, irradiation dose rate) of the charged particle beam P irradiated to the neutron beam output portions 8A, 8B. The second transfer unit 12A and the third transfer unit 12B may include a charged particle beam scanning unit 14 as needed (see FIG. 4). The charged particle beam scanning unit 14 scans the charged particle beam P and performs irradiation control of the charged particle beam P of the target T (see FIG. 4). The charged particle beam scanning unit 14 controls, for example, the irradiation position of the charged particle beam P on the target T.

如第4圖所示，中子束輸出部8A包括：用於產生中子束N的靶T；用於使中子束N減速的減速構件15；及屏蔽體16。減速構件15及屏蔽體16構成調整器。中子束輸出部8A與中子束輸出部8B具有彼此相同的結構，因此本說明書中對中子束輸出部8A進行說明，而省略中子束輸出部8B的說明。 As shown in Fig. 4, the neutron beam output unit 8A includes a target T for generating a neutron beam N, a decelerating member 15 for decelerating the neutron beam N, and a shield 16. The speed reducing member 15 and the shield 16 constitute a adjuster. Since the neutron beam output unit 8A and the neutron beam output unit 8B have the same configuration, the neutron beam output unit 8A will be described in the present specification, and the description of the neutron beam output unit 8B will be omitted.

靶T受到帶電粒子束P的照射而產生中子束N。靶T例如由鈹(Be)形成，且呈直徑為160mm的圓形。靶並不限於板狀(固體)，亦可以係液態等其他形態。 The target T is irradiated with the charged particle beam P to generate a neutron beam N. The target T is formed, for example, of beryllium (Be) and has a circular shape with a diameter of 160 mm. The target is not limited to a plate shape (solid), and may be in other forms such as a liquid state.

減速構件15使從靶T射出的中子束N減速。藉由減 速構件15被減速且被減至規定能量的中子束N亦被稱為治療用中子束。減速構件15可以呈例如由不同的複數個材料層疊而成的層疊結構。減速構件15的材料依據帶電粒子束P的能量等諸多條件來適當選擇。例如，當來自加速器7(參閱第2圖)的輸出為30MeV的質子束，且作為靶T使用鈹靶時，作為減速構件15的材料可使用鉛、鐵、鋁或氟化鈣。當來自加速器7的輸出為11MeV的質子束，且作為靶T使用鈹靶時，作為減速構件15的材料可使用重水(D2O)或氟化鉛。當來自加速器7的輸出為2.8MeV的質子束，且作為靶T使用鋰靶時，作為減速構件15的材料可使用Fluental(商品名稱：鋁、氟化鋁、氟化鋰的混合物)。當來自加速器7的輸出為50MeV的質子束，且作為靶T使用鎢靶時，作為減速構件15的材料可使用鐵或Fluental。 The speed reduction member 15 decelerates the neutron beam N emitted from the target T. The neutron beam N that is decelerated by the decelerating member 15 and reduced to a predetermined energy is also referred to as a neutron beam for treatment. The speed reducing member 15 may have a laminated structure in which, for example, a plurality of different materials are laminated. The material of the speed reducing member 15 is appropriately selected depending on various conditions such as the energy of the charged particle beam P. For example, when the output from the accelerator 7 (see FIG. 2) is a proton beam of 30 MeV and the target is used as the target T, lead, iron, aluminum or calcium fluoride can be used as the material of the reduction member 15. When the output from the accelerator 7 is a proton beam of 11 MeV and the target is used as the target T, heavy water (D 2 O) or lead fluoride can be used as the material of the speed reducing member 15. When the output from the accelerator 7 is a proton beam of 2.8 MeV and a lithium target is used as the target T, Fluental (trade name: a mixture of aluminum, aluminum fluoride, and lithium fluoride) can be used as the material of the decelerating member 15. When the output from the accelerator 7 is a 50 MeV proton beam and the tungsten target is used as the target T, iron or Fluental may be used as the material of the decelerating member 15.

屏蔽體16進行屏蔽，以防中子束N及伴隨該中子束N的產生而產生的γ射線等放射線放射到外部。屏蔽體16的至少一部份埋入於隔開帶電粒子束生成室5a與照射室4A的牆W1(參閱第1圖)。 The shield 16 is shielded from radiation such as gamma rays generated by the generation of the neutron beam N and the generation of the neutron beam N to the outside. At least a portion of the shield 16 is buried in the wall W1 that separates the charged particle beam generating chamber 5a from the irradiation chamber 4A (see Fig. 1).

中子束輸出部8A中，帶電粒子束P照射於靶T，藉此產生中子束N。產生的中子束N被減速構件15減速。從減速構件15射出的中子束N通過準直器17，照射到治療台2上的患者S。中子束N包含高速中子束、超熱中子束及熱中子束，還伴有γ射線。其中，主要由熱中子束與攝入到患者S體內的腫瘤中的硼進行核反應，而發揮有效 的治療效果。中子束N的射束中包含的超熱中子束的一部份亦在患者S的體內被減速而成為發揮上述治療效果的超熱中子束。超熱中子束是能量為0.5eV以下的中子束。 In the neutron beam output unit 8A, the charged particle beam P is irradiated onto the target T, whereby the neutron beam N is generated. The generated neutron beam N is decelerated by the decelerating member 15. The neutron beam N emitted from the decelerating member 15 passes through the collimator 17 and is irradiated to the patient S on the treatment table 2. The neutron beam N contains a high-speed neutron beam, an epithermal neutron beam, and a thermal neutron beam, and is accompanied by gamma rays. Among them, the thermal neutron beam is mainly reacted with boron in the tumor in the patient S, and it is effective. The therapeutic effect. A portion of the epithermal neutron beam contained in the beam of the neutron beam N is also decelerated in the body of the patient S to become an epithermal neutron beam that exerts the above-described therapeutic effect. The epithermal neutron beam is a neutron beam with an energy of less than 0.5 eV.

其中，本說明書中，以中子束N的射出方向為基準，如下設定XYZ坐標系(參閱第1圖、第4圖至第7圖、第9圖至第14圖)。 In the present specification, the XYZ coordinate system is set as follows based on the emission direction of the neutron beam N (see FIGS. 1 , 4 to 7 , and 9 to 14 ).

X軸：沿著從中子束輸出部8A射出的中子束N的射出方向延伸的軸 X-axis: an axis extending along the emission direction of the neutron beam N emitted from the neutron beam output portion 8A

Y軸：沿著與X軸正交的方向延伸的軸 Y-axis: an axis extending in a direction orthogonal to the X-axis

Z軸：沿著相對於X軸及Y軸垂直的方向(相對於地面F垂直的方向)延伸的軸 Z-axis: an axis extending in a direction perpendicular to the X-axis and the Y-axis (a direction perpendicular to the ground F)

接著，對照射室4A、4B進行說明。如第1圖及第2圖所示，中子束捕捉療法系統1具備2個照射室4A、4B。照射室4A配置於第2傳輸部12A延伸的方向的延長線上。照射室4B配置於第3傳輸部12B延伸的方向的延長線上。 Next, the irradiation chambers 4A and 4B will be described. As shown in FIGS. 1 and 2, the neutron beam capturing therapy system 1 includes two irradiation chambers 4A and 4B. The irradiation chamber 4A is disposed on an extension line in the direction in which the second transport portion 12A extends. The irradiation chamber 4B is disposed on an extension line in a direction in which the third transport portion 12B extends.

還能夠向與第2傳輸部12A或第3傳輸部12B延伸的方向交叉的方向取出中子束N。此時，照射室4A不限於配置在第2傳輸部12A延伸的方向的延長線上，可以配置在與中子束N的取出方向相對應的位置。照射室4B不限於配置在第3傳輸部12B延伸的方向的延長線上，可以配置在與中子束N的取出方向相對應的位置。照射室4A與照射室4B具有相同的結構，因此本說明書中對照射室4A進行說明，而省略照射室4B的說明。 It is also possible to take out the neutron beam N in a direction crossing the direction in which the second transfer portion 12A or the third transfer portion 12B extends. At this time, the irradiation chamber 4A is not limited to being disposed on an extension line in the direction in which the second transport portion 12A extends, and may be disposed at a position corresponding to the direction in which the neutron beam N is taken out. The irradiation chamber 4B is not limited to an extension line disposed in the direction in which the third transport portion 12B extends, and may be disposed at a position corresponding to the direction in which the neutron beam N is taken out. Since the irradiation chamber 4A has the same configuration as the irradiation chamber 4B, the irradiation chamber 4A will be described in the present specification, and the description of the irradiation chamber 4B will be omitted.

照射室4A係為了對患者S照射中子束N而在室內安置患者S的房間。照射室4A的大小例如為寬度3.5m×縱深5m×高度3m。照射室4A具有被屏蔽牆W2包圍的屏蔽空間。照射室4A的出入口設有門D1。照射室4A的出入口具有可供治療台2通行的大小。 The irradiation room 4A is a room in which the patient S is placed indoors in order to irradiate the patient S with the neutron beam N. The size of the irradiation chamber 4A is, for example, a width of 3.5 m × a depth of 5 m × a height of 3 m. The irradiation room 4A has a shield space surrounded by the shield wall W2. A door D1 is provided at the entrance and exit of the irradiation room 4A. The entrance and exit of the irradiation chamber 4A has a size that allows the treatment table 2 to pass.

如第4圖所示，在屏蔽體16的照射室4A側的表面設有罩(牆體)18。罩18構成照射室4A的內側牆面的一部份。罩18上設有成為中子束N的出入口的準直器安裝部18a。準直器安裝部18a係用於嵌入準直器17的開口。 As shown in Fig. 4, a cover (wall) 18 is provided on the surface of the shield 16 on the side of the irradiation chamber 4A. The cover 18 constitutes a part of the inner wall surface of the irradiation chamber 4A. The cover 18 is provided with a collimator mounting portion 18a that serves as an entrance and exit of the neutron beam N. The collimator mounting portion 18a is for inserting the opening of the collimator 17.

屏蔽牆W2例如係厚度為2m以上的混凝土製牆，抑制放射線的透射。屏蔽牆W2防止放射線從照射室4A的內部透射到外部。屏蔽牆W2與屏蔽牆W1一體形成。 The shield wall W2 is, for example, a concrete wall having a thickness of 2 m or more, and suppresses transmission of radiation. The shield wall W2 prevents radiation from being transmitted from the inside of the irradiation chamber 4A to the outside. The shield wall W2 is formed integrally with the shield wall W1.

門D1係可閉合照射室4A的出入口的門。門D1係抑制放射線的透射的屏蔽門。門D1例如由聚乙烯、鉛等可抑制放射線的透射的材質形成。門D1藉由馬達等將驅動力施加到設置於例如地面F的導軌上，以進行開閉。門D1被打開時，治療台2能夠在聯絡室6A與照射室4A之間移動。門D1被閉合時，治療台2無法在聯絡室6A與照射室4A之間移動。並且，門D1被閉合時，可防止照射線通過照射室4A的出入口而透射。 The door D1 is a door that can close the entrance and exit of the irradiation chamber 4A. The door D1 is a screen door that suppresses the transmission of radiation. The door D1 is formed of, for example, a material that suppresses the transmission of radiation, such as polyethylene or lead. The door D1 applies a driving force to a guide rail provided on, for example, the floor F by a motor or the like to open and close. When the door D1 is opened, the treatment table 2 is movable between the communication room 6A and the irradiation room 4A. When the door D1 is closed, the treatment table 2 cannot move between the communication room 6A and the irradiation room 4A. Further, when the door D1 is closed, the irradiation line can be prevented from being transmitted through the entrance and exit of the irradiation chamber 4A.

由於門D1較重，因此作為用於驅動門D1的機構，使用高轉矩馬達或減速器等。門D1可具有通知工作人員出入照射室4A的功能。例如，藉由在照射室4A的室內配置有治療台2的狀態下關閉門D1，確認工作人員從照 射室4A退避。 Since the door D1 is heavy, a high torque motor, a speed reducer, or the like is used as a mechanism for driving the door D1. The door D1 may have a function of notifying the worker to enter and exit the irradiation room 4A. For example, by closing the door D1 in a state where the treatment table 2 is placed in the room of the irradiation room 4A, it is confirmed that the worker is taking photos. The shooting chamber 4A is retracted.

接著，對準備室3A進行說明。準備室3A係用於為了在照射室4A中對患者S照射中子束N而實施必要的工作的房間。準備室3A配置成在Y軸方向上隔著聯絡室6A與照射室4A分開。準備室3A與準備室3B具有相同的結構，因此本說明書中對準備室3A進行說明，而省略準備室3B的說明。 Next, the preparation chamber 3A will be described. The preparation room 3A is a room for performing necessary work for irradiating the patient S with the neutron beam N in the irradiation room 4A. The preparation chamber 3A is disposed to be separated from the irradiation chamber 4A via the communication chamber 6A in the Y-axis direction. Since the preparation chamber 3A has the same configuration as the preparation chamber 3B, the preparation chamber 3A will be described in the present specification, and the description of the preparation chamber 3B will be omitted.

準備室3A中，例如實施將患者S束縛在治療台2或準直器17與患者S的對位。因此，準備室3A具有可供工作人員在收容於室內的治療台2的周圍輕鬆地進行準備工作的大小。 In the preparation chamber 3A, for example, the alignment of the patient S to the treatment table 2 or the alignment of the collimator 17 with the patient S is carried out. Therefore, the preparation room 3A has a size that allows the worker to easily perform preparation work around the treatment table 2 housed in the room.

在準備室3A與照射室4A之間的未形成有聯絡室6A的區域設置有隔開準備室3A與照射室4A的牆W3。牆W3的厚度例如為3.2m。亦即，準備室3A與照射室4A沿著Y軸方向僅分開3.2m。 A wall W3 separating the preparation chamber 3A and the irradiation chamber 4A is provided in a region between the preparation chamber 3A and the irradiation chamber 4A where the communication chamber 6A is not formed. The thickness of the wall W3 is, for example, 3.2 m. That is, the preparation chamber 3A and the irradiation chamber 4A are separated by only 3.2 m along the Y-axis direction.

並且，準備室3A的出入口上設有門D2。準備室3A的出入口連通準備室3A與聯絡室6A。門D2係可閉合準備室3A的出入口的門，且係抑制放射線的透射的屏蔽門。門D2例如由聚乙烯、鉛等可抑制放射線的透射的材質形成。門D2藉由馬達等將驅動力施加到設置於例如地面F的導軌上，以進行開閉。門D2被打開時，治療台2能夠在準備室3A與聯絡室6A之間移動。門D2被閉合時，治療台2無法在準備室3A與聯絡室6A之間移動。並且，門D2被閉合時，可防止照射線通過準備室3A的 出入口而透射。作為用於驅動門D2的機構使用高轉矩馬達和減速器等。 Further, a door D2 is provided at the entrance and exit of the preparation room 3A. The entrance and exit of the preparation room 3A communicates with the preparation room 3A and the communication room 6A. The door D2 is a door that closes the entrance and exit of the preparation chamber 3A, and is a screen door that suppresses the transmission of radiation. The door D2 is formed of, for example, a material that suppresses the transmission of radiation, such as polyethylene or lead. The door D2 applies a driving force to a guide rail provided on, for example, the floor surface F by a motor or the like to open and close. When the door D2 is opened, the treatment table 2 is movable between the preparation chamber 3A and the communication chamber 6A. When the door D2 is closed, the treatment table 2 cannot move between the preparation chamber 3A and the communication room 6A. And, when the door D2 is closed, the irradiation line can be prevented from passing through the preparation chamber 3A. Transmitted through the entrance and exit. A high torque motor, a speed reducer, and the like are used as a mechanism for driving the door D2.

聯絡室6A係用於連通準備室3A與照射室4A之間，並移動束縛有患者S的狀態的治療台2的房間。聯絡室6A沿著Y軸方向直線形成。聯絡室6A具有供治療台2通過的寬度。並且，聯絡室6A具有可供工作人員步行通行的高度。關於聯絡室6A的大小，作為一例，係寬度1.5m×縱深3.2m×高度2.0m。聯絡室6B連通準備室3B與照射室4B之間，並具有與聯絡室6A相同的結構，因此本說明書中省略聯絡室6B的說明。 The communication room 6A is for connecting the room between the preparation room 3A and the irradiation room 4A, and moving the treatment table 2 in a state in which the patient S is restrained. The communication room 6A is formed linearly along the Y-axis direction. The communication room 6A has a width through which the treatment table 2 passes. Also, the communication room 6A has a height that allows the staff to walk. The size of the communication room 6A is, for example, 1.5 m in width × 3.2 m in depth × 2.0 m in height. Since the communication room 6B is connected between the preparation room 3B and the irradiation room 4B and has the same configuration as the communication room 6A, the description of the communication room 6B is omitted in the present specification.

中子束捕捉療法系統1具備用於使治療台2在準備室3A、3B與照射室4A、4B之間行走的軌道19A、19B。接著，對軌道19A進行說明。軌道19A從準備室3A的內部通過聯絡室6A一直設置到照射室4A的內部。 The neutron beam capturing therapy system 1 includes rails 19A and 19B for moving the treatment table 2 between the preparation chambers 3A and 3B and the irradiation chambers 4A and 4B. Next, the track 19A will be described. The rail 19A is provided from the inside of the preparation chamber 3A through the communication chamber 6A to the inside of the irradiation chamber 4A.

如第5圖至第7圖所示，軌道19A具備：一對導軌20，引導治療台2的移動；一對行走用凹槽部21，分別收容一對導軌20；及一對支撐構件22，配置於行走用凹槽部21內的導軌20的兩側。 As shown in FIGS. 5 to 7, the rail 19A includes a pair of guide rails 20 for guiding the movement of the treatment table 2, a pair of traveling groove portions 21 for accommodating a pair of guide rails 20, and a pair of support members 22, Both sides of the guide rail 20 disposed in the traveling groove portion 21 are disposed.

The pair of guide rails are linear when viewed from above. The guide rail 20 is fixed to the bottom of the traveling groove portion 21.

導軌20與後述的滑塊(導軌卡合部)23卡合。滑塊23沿著導軌20移動。一對支撐構件22的剖面呈L字形(參閱第6圖及第7圖)。俯視觀察時，一對支撐構件22呈直線形，並沿著導軌20延伸。收容於行走用凹槽部21內的導軌20及一對支撐構件22配置得比地面低，以免突出在地面的上方。並且，地面與導軌20及一對支撐構件22之間的上下方向的差大致等於後述的行走用皮帶BT1的厚度。 The guide rail 20 is engaged with a slider (rail engagement portion) 23 which will be described later. The slider 23 moves along the guide rail 20. The pair of support members 22 have an L-shaped cross section (see FIGS. 6 and 7). The pair of support members 22 are linear in plan view and extend along the guide rails 20. The guide rail 20 and the pair of support members 22 accommodated in the traveling groove portion 21 are disposed lower than the ground so as not to protrude above the ground. Further, the difference between the vertical direction between the floor and the guide rail 20 and the pair of support members 22 is substantially equal to the thickness of the traveling belt BT1 to be described later.

並且，X軸方向上，導軌20與一對支撐構件22之間形成有能夠供滑塊23通過的間隙。 Further, a gap through which the slider 23 can pass is formed between the guide rail 20 and the pair of support members 22 in the X-axis direction.

如第1圖及第2圖所示，中子束捕捉療法系統1具備管理室24。管理室24係用於管理利用中子束捕捉療法系統1實施的整個製程的房間。管理室24中設有用於操作中子束產生部5的控制裝置25和用於監視照射室4A、4B的內部的監視設備26等。並且，管理室24中設有用於控制治療台2的動作的治療台控制部27。 As shown in FIGS. 1 and 2, the neutron beam capturing therapy system 1 includes a management room 24. The management room 24 is for managing rooms in the entire process implemented by the neutron beam capture therapy system 1. The management room 24 is provided with a control device 25 for operating the neutron beam generating portion 5, a monitoring device 26 for monitoring the inside of the irradiation chambers 4A, 4B, and the like. Further, the management room 24 is provided with a treatment table control unit 27 for controlling the operation of the treatment table 2.

管理室24以與2個準備室3A、3B相鄰的方式配置於準備室3A與準備室3B之間。管理室24在一個拐角部與準備室3A相鄰，在另一個拐角部與準備室3B相鄰。管理室24與準備室3A之間配置有能夠目視準備室3A的室內的窗28A。管理室24與準備室3B之間配置有能夠目視準備室3B的室內的窗28B。 The management room 24 is disposed between the preparation chamber 3A and the preparation chamber 3B so as to be adjacent to the two preparation chambers 3A and 3B. The management room 24 is adjacent to the preparation chamber 3A at one corner portion and adjacent to the preparation chamber 3B at the other corner portion. A window 28A in the room where the preparation room 3A can be visually observed is disposed between the management room 24 and the preparation room 3A. A window 28B in the room where the preparation room 3B can be visually observed is disposed between the management room 24 and the preparation room 3B.

監視設備26與例如設置於照射室4A、4B的室內的攝像機29連接。監視設備26具有圖像顯示部，能夠顯示 用攝像機29拍攝的圖像。 The monitoring device 26 is connected to, for example, a camera 29 provided in the room of the irradiation chambers 4A, 4B. The monitoring device 26 has an image display portion that can be displayed The image taken with the camera 29.

管理室24內至少能夠有1名管理員進入。管理人員能夠利用控制裝置25、監視設備26及治療台控制部27管理中子束捕捉療法系統1中的整個製程。 At least one administrator can enter in the management room 24. The manager can manage the entire process in the neutron beam capturing therapy system 1 by the control device 25, the monitoring device 26, and the treatment table control unit 27.

例如，進入管理室24的管理人員從管理室24的室內藉由目視確認準備室3A、3B內的準備工作的情況。進入管理室24的管理人員藉由操作控制裝置25，例如控制射束傳輸線路9，以便對與應照射中子束N的照射室4A對應的靶T照射帶電粒子束P。進入管理室24的管理人員藉由操作控制裝置25，控制中子束N的照射的開始和停止。 For example, the manager who has entered the management room 24 visually confirms the preparation work in the preparation rooms 3A and 3B from the inside of the management room 24. The manager entering the management room 24 controls the beam transmission line 9 by operating the control device 25, for example, to irradiate the target particle T corresponding to the irradiation chamber 4A to be irradiated with the neutron beam N with the charged particle beam P. The manager entering the management room 24 controls the start and stop of the irradiation of the neutron beam N by operating the control device 25.

接著，對使用中子束捕捉療法系統1的中子束捕捉療法的流程進行說明。 Next, the flow of the neutron beam capturing therapy using the neutron beam capturing therapy system 1 will be described.

首先，對患者S進行進入準備室3A(中子束捕捉療法系統1)之前的規定的事前準備。接著，患者S及工作人員進入準備室3A內，工作人員幫助患者S使其躺臥在頂板31上。接著，工作人員使用束縛件將患者S的身體束縛在頂板31。接著，實施患者S的照射部位與準直器17的照射中心軸線C的對位。 First, the patient S is prepared in advance before entering the preparation room 3A (neutron beam capturing therapy system 1). Next, the patient S and the worker enter the preparation room 3A, and the worker assists the patient S to lie on the top plate 31. Next, the worker binds the body of the patient S to the top plate 31 using the binding member. Next, the alignment of the irradiation site of the patient S with the irradiation center axis C of the collimator 17 is performed.

接著，治療台2向照射室4A移動。此時，可由管理室24的管理人員決定能否進入照射室4A。例如，由工作人員向管理人員報告已完成準備室3A中的工作的內容。得到報告的管理人員在判斷為可以進入照射室4A時，打開隔開準備室3A與聯絡室6A的門D2。並且，此時，保持屏蔽塊56被打開的(未藉由屏蔽塊56關閉凹槽44)狀態，或者藉由門D2的打開而打開屏蔽塊56。 Next, the treatment table 2 is moved to the irradiation room 4A. At this time, it is possible to determine whether or not the irradiation chamber 4A can be entered by the manager of the management room 24. For example, the staff member reports to the manager that the contents of the work in the preparation room 3A have been completed. When the manager who has received the report determines that it is possible to enter the irradiation room 4A, the door D2 that separates the preparation room 3A from the communication room 6A is opened. Also, at this time, the state in which the shield block 56 is opened (the groove 44 is not closed by the shield block 56) is maintained, or the shield block 56 is opened by the opening of the door D2.

若治療台2從準備室3A移動到聯絡室6A內，則門D2被關閉，並且藉由屏蔽塊56關閉凹槽44。門D2被關閉之後，隔開聯絡室6A與照射室4A的門D1被打開。並且，藉由門D1的打開而打開屏蔽塊55。門D1、D2的開閉順序並不限定於該順序，例如可同時打開門D1與門D2。另外，亦可以臨時打開門D1及門D2，以便能夠在 關閉門D1及門D2之後從準備室3A藉由目視確認治療台2移動到照射室4A內的狀態。 If the treatment table 2 is moved from the preparation chamber 3A into the communication chamber 6A, the door D2 is closed, and the groove 44 is closed by the shield block 56. After the door D2 is closed, the door D1 that separates the communication room 6A from the irradiation room 4A is opened. And, the shield block 55 is opened by the opening of the door D1. The order of opening and closing of the doors D1 and D2 is not limited to this order, and for example, the doors D1 and D2 can be simultaneously opened. In addition, it is also possible to temporarily open the door D1 and the door D2 so as to be able to After the door D1 and the door D2 are closed, the state in which the treatment table 2 is moved into the irradiation chamber 4A is visually confirmed from the preparation chamber 3A.

若治療台2從聯絡室6A移動到照射室4A內，則準直器17安裝到準直器安裝部18a。接著，照射室4A的出入口藉由門D1而被關閉。同樣，利用屏蔽塊55在門D1的下方關閉凹槽44。之後，若管理人員操作控制裝置25，則開始中子束N的照射，進行患者S的治療。關於照射時間，作為一例係1小時左右。藉由設置於照射室4A的室內的攝像機29拍攝治療中的患者S的情況。藉由攝像機29拍攝的圖像顯示於管理室24的監視設備26的監視器上。管理人員利用監視器管理治療中的患者S的情況。管理人員在確認到治療中的患者S有異常時，進行中止照射的判斷。 When the treatment table 2 is moved from the communication chamber 6A into the irradiation chamber 4A, the collimator 17 is attached to the collimator mounting portion 18a. Next, the entrance and exit of the irradiation chamber 4A is closed by the door D1. Also, the groove 44 is closed under the door D1 by the shield block 55. Thereafter, when the manager operates the control device 25, the irradiation of the neutron beam N is started, and the treatment of the patient S is performed. The irradiation time is about 1 hour as an example. The patient S in the treatment is photographed by the camera 29 provided in the room of the irradiation room 4A. The image taken by the camera 29 is displayed on the monitor of the monitoring device 26 of the management room 24. The manager uses the monitor to manage the condition of the patient S in the treatment. When the manager confirms that there is an abnormality in the patient S during the treatment, the manager makes a judgment to suspend the irradiation.

若經過規定的照射時間，則控制裝置25自動停止中子束N的照射。接著，將治療台2移動至準備室3A。接著，工作人員在準備室3A的室內解除固定患者S的束縛件，向準備室3A的室外引導患者S。藉由以上步驟，完成使用中子束捕捉療法系統1的中子束捕捉療法。 When a predetermined irradiation time elapses, the control device 25 automatically stops the irradiation of the neutron beam N. Next, the treatment table 2 is moved to the preparation chamber 3A. Next, the worker releases the restraint of the patient S in the room of the preparation room 3A, and guides the patient S to the outside of the preparation room 3A. The neutron beam capture therapy using the neutron beam capture therapy system 1 is completed by the above steps.
