Spectrally generated stereo x-ray imaging

Abstract

The present invention relates to X-ray imaging. There is provided an X-ray device (100). The X-ray device (100) comprises an X-ray generator (10) and an X-ray detector (12). The X-ray generator (10) is configured to generate a polychromatic X-ray beam in a frequency range for a subject to be imaged. The polychromatic X-ray beam is configured to have an energy dependent angulation with respect to the X-ray detector (20). The X-ray detector (20) is configured to acquire a plurality of energy-resolved absorption images of the subject, which are usable for generating a stereo-absorption image of the subject. This new imaging modality can be seen as being in-between purely projective imaging and full 3D modality. Thereby, it can be used in an early stage of the diagnostic pathway for clarifying indications without the need for acquiring full 3D images. The X-ray device may relax the requirements on the exact patient positioning for subtle exams (e.g., ankle lateral) since the radiologist can compensate for mis-positionings after the image acquisition
