Abstract: The invention relates to a system for reconstructing an image of an object. The system (100) comprises means (110) providing projection data acquired by an imaging unit, like a CT system, with an FOV, means (120) generating estimated image data indicative of a part of an object (20) located outside the FOV (210), means (130) estimating virtual projection data based on virtual settings of a virtual imaging unit comprising a virtual FOV, means (140) generating fused projection data by fusing the provided projection data with the virtual projection data, and means (150) reconstructing a final image. This allows basing the reconstruction on a complete set of projection information for the object and thus providing an image with a high image quality.
