Imaging method and device with dual reading scanner.

An imaging method fr imaging a region of investigation (2) of an object (1), comprises the steps of generating an enery input beam (3) with an energy beam source (10), irradiation the region of investigation (2) with energy input beam components (4) of the energy input (3) along a plurality of projection directions, the enery input beam components (4) being formed with a framed mask (40) being arranged between the enery input beam (10) and teh object (1) and including frame mask windows (41), measuring first integrated attenuation values of the energy input beam components (4) with an outer detector device (21) arranged outside the frame mask (40), measuring second integrated attunation values of the enery input beam components (4) with a frame mask detector device (24) being arranged on an inner surface of the frame mask (40), and reconstructing an image of the region of investigation (2) bades on the first and second integrated attenuation values. Furthermore, an imaging device (100) for imaging a region of investigation (2) of an object (1) is described
