Abstract
The invention relates to a subject support device () to be used in a projection data acquisition apparatus () for acquiring projection data of a subject (). The subject support device comprises a support component () providing a support surface () for supporting the subject while acquiring the projection data, a diffraction grating () for diffracting x-rays, and a moving unit () 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 () 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.
