RD-19564 PARALLEL PROCESSING METHOD AND APPARATUS FOR RECONSTRUCTING A THREE-DIMENSIONAL COMPUTERIZED TOMOGRAPHY (CT) IMAGE OF AN OBJECT FROM CONE BEAM PROJECTION DATA OR FROM PLANAR INTEGRALS A methods and apparatus is disclosed for 3D CT image reconstruction involving a conventional 2D CT reconstruction. A 3D image of the object is reconstructed sliceby-slice by employing, for each slice, a 2D reconstruction procedure, for example, filtered backprojection, on the values of the 2D projection images in the plane of the slice to calculate a 2D image of the object for each of the slices. |
