Title (EN) PROJECTION DATA ACQUISITION APPARATUS AND SUBJECT SUPPORT DEVICE
(FR) APPAREIL D'ACQUISITION DE DONNÉES DE PROJECTION ET DISPOSITIF DE SUPPORT DE SUJET
Abstract:
(EN) The invention relates to a subject support device (1) to be used in a projection data acquisition apparatus (2) for acquiring projection data of a subject (3). The subject support device comprises a support component (4) providing a support surface (5) for supporting the subject while acquiring the projection data, a diffraction grating (6) for diffracting x-rays, and a moving unit (7, 8) for moving the support component and the diffraction grating relative to each other. This relative movement can allow for a movement of the support component such that the subject is moved through x-rays (16) for determining projection data of different parts of the subject, while the diffraction grating can still be traversed by the x-rays. These projection data can be used for generating a relatively large phase- contrast and/or dark- field projection image.
(FR) L'invention concerne un dispositif de support de sujet (1) destiné à être utilisé dans un appareil d'acquisition de données de projection (2) en vue d'acquérir des données de projection d'un sujet (3). Le dispositif de support de sujet comprend un élément de support (4) fournissant une surface de support (5) permettant de supporter le sujet tout en acquérant les données de projection, un réseau de diffraction (6) permettant de diffracter les rayons X, et une unité de déplacement (7, 8) permettant de déplacer l'élément de support et le réseau de diffraction l'un par rapport à l'autre. Ce mouvement relatif peut permettre un mouvement de l'élément de support de sorte que le sujet soit déplacé à travers des rayons X (16) pour déterminer des données de projection de différentes parties du sujet, tandis que le réseau de diffraction peut encore être traversé par les rayons X. Ces données de projection peuvent être utilisées pour générer une image de projection à contraste de phase et/ou sur fond noir relativement grande.
