1. A method for obtaining tomosynthesis images of an object of interest using an imaging system, wherein the imaging system comprises an X-ray source facing a detector on which the object of interest is positioned, the method comprising: 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; applying at least one filter to the acquired projected 2D images to obtain filtered, projection images of the object of interest; and determining a set of reconstruction slices of the object of interest from a backprojection of at least two of the filtered, projection images, the set of reconstruction slices being the filtered, reconstructed volume of the object of interest, wherein at least one of the at least one filter is an adaptive type filter.
