Description
過去数十年の間、粒子照射治療と診断の分野には相当な進歩があった。外部粒子照射治療加速器、近接照射治療および他の特定化照射治療装置の性能は急速に改良されつつある。治療用粒子ビームの品質と適合性において生じている発達には、新たな標的とフィルター、改良された加速器、新規応用を通したビーム形成の柔軟性、視準器(collimator)、走査システム、およびビーム補償技術を含む。また改良された線量と幾何治療検定の方法が導入された。さらに、送信されたビームの強度分布を生物的に最適化することが可能な新規な治療計画システムが、いまや入手することが可能である。
本発明は、先行技術のこれら、上記欠点を克服するものである。
本発明の目的は、偏心する(エクセントリックな)ガントリーをもつ照射システムを提供するにある。
本発明の他の目的は、ガントリー周辺に配置される多重の治療室に照射ビームを伝送する照射システムを提供することである。
本発明特有の目的は、第1の治療室の患者へ臨床治療として照射ビームを伝送し、一方で、同時に照射システムのシミュレーターとビーム準備部分が使用されて、照射準備と照射の準備過程として隣接の治療室の他の患者へなされる照射システムが提供される。
本発明の他の目的は、多重治療室で使用される照射治療とシミュレーション機能が集積されてなる照射システムが提供される。
これらと他の目的は、添付の特許請求の範囲により明確となる。
−異なる治療室のいくつかの対象の照射に有効に使用される;
−実際の照射治療が同時に他の室で行われる間に、治療の準備、シミュレーションおよび/または対象の退出操作をいくつかの室で行うことを可能とする;
−所定時間に照射され得る対象の合計数の能力を増加させる;
−簡素なガントリー設計と小さい偏向磁石半径と柔軟なビーム指向選択により軽イオン照射に使用を可能とする;
−固定ビーム線配列による多重の高価なイソセントリックな機器の代わりに、ビーム指向が可変である低価格の一つの機器が多重治療室で有利に使用され得るので、設置コストが有利に減額できる;
−治療助成チームを煩わせることなく、個々のケアと正確な患者の準備に関して十分な注意を患者に払うことができる。
本発明の他の特徴は、以下の本発明の実施態様の説明から理解される。
目的と特徴とともに本発明は、以下の説明を参照して最も良く理解されることができ、添付の図面も共に利用され、その内容は以下のとおりである:

図3は、図2と比較して他の治療室で患者を照射する図2の照射システムを説明する図である;
図4は、垂直と水平のビーム照射が可能な異なる治療室を有する偏心ガントリーによる本発明の照射システムの他の態様を説明する図である。
図5は、斜め、垂直および水平のビーム照射が可能な異なる治療室を有する偏心ガントリーによる本発明の照射システムの他の態様を説明する図である。
図6は、二つのビームを同時に治療室へ伝送する二つの偏心ガントリーによる本発明の照射システムの他の態様を説明する図である。
図7は、本発明による照射システムの偏心ガントリー態様の断面図である。

図11は、本発明による照射システムのさらに別の他の態様の断面図である。
図面において、対応するまたは類似の要素には、同一の参照番号が付される。
図7の走査システムはまた、単一の均一ビームを得るために仕切られて、規則的な二重または一重の散乱箔システムを使用することも出来る。
