<p>An imaging method for imaging a region of investigation (2) of an object (1), comprises the steps of generating an energy input beam (3) with an energy beam source (10), irradiating the region of investigation (2) with energy input beam components (4) of the energy input beam (3) along a plurality of projection directions, the energy input beam components (4) being formed with a frame mask (40) being arranged between the energy input beam (10) and the 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 attenuation values of the energy 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) based 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.</p> |
