Appl.No PCT/EP2021/084465 Applicant KONINKLIJKE PHILIPS N.V. Inventor KOEHLER, Thomas
A phase contrast X-ray imaging system with field of view (FOV) visualization and a holder arranged to hold a grating and a light field projector to enable the FOV illumination, for an operator to visualize the region on a subject that will be irradiated with X-rays. By taking advantage of the holder of the necessary object in the X-ray beam path (i.e. the grating) to hold a light field projector to illuminate the FOV, the solution is naturally more compact to implement and the mechanical complexity is kept to a minimum. The light field projector provides a sharp, well-defined area with a distinct outline of the FOV.
