Abstract
【解決手段】放射線治療システム100は、照射システムと結合した磁気共鳴撮像(MRI)システム102を有する。MRIシステムは、放射線治療に適した放射線ビームを放出する1つ以上の線形加速器(ライナック)および分離した磁石システムを有する。分離した磁石システムは、ギャップによって隔てられた第1主磁石及び第2主磁石を有する。ガントリー106は、ギャップ内で第1主磁石と第2主磁石との間に設けられ、照射システムの(複数の)ライナックを支持している。ガントリーは、MRIシステムとは独立して回転可能で、(複数の)ライナックの角度を再設定できる。遮蔽はまた、磁気遮蔽及び/又はRF遮蔽として供される。磁気遮蔽は、MRI磁石による磁場から(複数の)ライナックを、RF遮蔽は、ライナックからのRF放射線からMRIシステムを遮蔽する。
