a method for obtaining tomosynthesis images of an object of interest using an imaging system , wherein the imaging system comprises an x - ray source arranged to facing a detector on which the object of interest is positioned . the method comprises acquiring a plurality of projected 2d images of the object of interest in a plurality of orientations identified relative to a perpendicular to the detector , wherein a zero orientation is closest to the perpendicular and applying at least one filter to the acquired projected 2d images to obtain filtered , projection images of the object of interest . the method further comprises determining a reconstruction slice of the object of interest from the backprojection of at least two of the filtered projections , the set of reconstruction slices being the filtered , reconstructed volume of the object of interest , wherein a filter used on the 2d projection images is an adaptive filter .
