Abstract
(EN)
When a location repeating a cyclic motion of a subject within a gantry is CT-photographed and reconstructed, the gantry is rotated in synchronization with the cyclic motion of the moving location to obtain an image in which the moving location is at standstill. Accordingly, it is possible to observe the flow of a contract medium or the like with the motion of an organ repeating a cyclic motion stopped.
(FR)
Selon l’invention, lors d’une tomographie informatisée et d’une reconstitution d’un organe animé d’un mouvement cyclique d’un sujet placé dans un portique, le portique est entraîné en rotation en synchronisme avec le mouvement cyclique de l’organe dans le but d’obtenir une image dans laquelle l’organe animé d’un mouvement cyclique est au repos. L’invention permet donc d’observer l’écoulement d’un milieu de contact alors que le mouvement d’un organe animé d’un mouvement cyclique est interrompu.
(JA)
 ガントリ内にある被検体の周期的な運動を繰返している部分をCT撮影して再構成する際に、運動部分の周期的な運動と同期してガントリを回転させることにより、運動部分の動きが止まった画像を得る。これにより、周期的な運動を繰返している臓器の動きを止めて、造影剤等の流れが観測可能となる。
