Abstract
A method for producing an image of an object includes scanning an object with an imaging apparatus to collect projection data of the object utilizing cone sampling. The projection data is rebinned in a row-wise, fan-to-parallel fashion to produce rebinned data and the rebinned data is view-weighted to produce view-weighted data. The method further includes filtering the view-weighted data utilizing a row-wise ramp filter to produce filtered data and generating an image of the object utilizing the filtered data and a three-dimensional (3D) backprojection.
