The present invention relates to a device for tomosynthesis imaging, the device comprising: a mask generator module (101) configured to generate a binary mask based on a geometric three-dimensional model of a scanned object an image capturing module (102) configured to scan a series of two-dimensional projection images of the object and an image processing module (103) configured to apply the generated binary mask during a reconstruction of a three-dimensional image volume from the scanned series of two-dimensional projection images and to restrict an extent of the reconstructed image volume to the extent of the geometric model.
