Abstract
In one embodiment, the present invention is a method for reconstructing a scanned CT image that includes steps of: acquiring projection data of an object utilizing a flat-panel detector; and filtering and backprojecting the projection data, without radially interpolating, to reconstruct a three-dimensional image of the object. This embodiment provides direct fan-parallel, three-dimensional reconstruction of computed tomographic images without loss of resolution associated with radial interpolation, while retaining imaging quality and backprojection speed gains associated with parallel reconstruction.
