Abstract

Systems, methods and apparatus are provided through which in one aspect, a three-dimensional (3D) image of an object is constructed from a plurality of two-dimensional (2D) images of the object using a specialized filter. In some embodiments, the specialized filter implements a linear ramp function, a windowing function, and/or a polynomial function. In some embodiments, the 3D image is back-projected from the filtered two-dimensional images, yielding a 3D image that has improved visual distinction of overlapping anatomic structures and reduced blurring.
