1. A method for producing cross-sectional image of an object by using a computed tomography imaging system, which includes a source of a conical beam of radiation and a multi-row detector array arranged on opposite sides of an axis of rotation, said method comprising: rotating the source and detector array about the axis of rotation; while rotating, collecting x-ray attenuation data samples from the multi-row detector array at a plurality of projection angles &bgr; to produce a set of projection data; applying a projection weighting image reconstruction technique to the set of projection data at a plurality of different center-view angles &bgr; 0 to produce a plurality of sub-images; and combining the plurality of sub-images to form a cross-sectional image of the object.
