Abstract
【解決手段】イメージング・システムのための方法及び装置(100)を提供する。このイメージング・システムは、回転部材に結合された静止部材を有するガントリを含んでいる。回転部材は回転部材の回転軸に近接して開放域を有する。X線源が回転部材に設けられている。X線検出器が回転部材に配設されて、X線源からのX線を受光するように構成され得る。一次巻線及び二次巻線(108、110)を円周に配設させた回転式変圧器(102、104)が、ガントリの回転可能部分を極めて高速に回転させる無接点型電力伝達システムの一部を形成することができ、一次巻線は静止部材に配設され、二次巻線は回転部材に配設される。
