1. A method for obtaining data, said method comprising: scanning an object using a CT imaging system having at least two detector rows to acquire projection data, wherein the projection data includes at least some data obtained from at least two rows of the detector array; reconstructing data representative of an image of the object utilizing the projection data, wherein said reconstruction includes pipelining the acquired projection data through a z-filtering pipeline of operations including column-filtering, tomographic filtering, and backprojection, wherein the column-filtering comprises a first interpolation operation comprising a first interpolation kernel and a second interpolation operation comprising a second interpolation kernel wherein the second interpolation kernel produces an equal but opposite data shift as the first interpolation kernel and wherein modifying at least one of the first and second interpolation kernels changes an amount of noise, slice thickness, and artifact suppression between an original sample and an interpolated sample; and outputting the reconstructed data to a display device.
