Abstract[English]
Embodiments of the present invention disclose a method and apparatus for positioning a movable component in X-ray imaging. The method comprises: acquiring a 3D image that is captured using a camera component and characterizes a motion process of a movable component; acquiring motion information of the movable component, detected by a motion sensor; positioning the movable component based on the 3D image and the motion information. The embodiments of the present invention combine the 3D image of the movable component with motion information of the movable component to position the movable component, so can increase the precision of positioning of the movable component, and in particular can improve image stitching quality and the precision of positioning of a detector, as well as being able to reduce the overlap requirements in image stitching and lower the exposure dose.[French]
Des modes de réalisation de la présente invention divulguent un procédé et un appareil de positionnement d'un composant mobile en imagerie par rayons X. Le procédé consiste à : acquérir une image 3D qui est capturée à l'aide d'un composant caméra et caractérise un processus de mouvement d'un composant mobile ; acquérir des informations de mouvement du composant mobile, détectées par un capteur de mouvement ; positionner le composant mobile sur la base de l'image 3D et des informations de mouvement. Les modes de réalisation de la présente invention combinent l'image 3D du composant mobile avec des informations de mouvement du composant mobile pour positionner le composant mobile, ce qui permet d'augmenter la précision de positionnement du composant mobile et peut, en particulier, améliorer la qualité d'assemblage d'images et la précision de positionnement d'un détecteur, tout en permettant de réduire les exigences de chevauchement dans l’assemblage d'images et de réduire la dose d'exposition.
