Abstract:

A method for reconstructing an image of an object utilizing a computed tomographic (CT) imaging system having a radiation source configured to project a beam of radiation through an object and towards a multislice detector array configured to sense attenuation of the radiation passing through the object; the method includes helically scanning an object to acquire a plurality of slices of projection data, generating a separate projection dataset for each of N separate detector rows wherein the separate projection datasets include detector row projection data and detector row conjugate projection data, combining the detector row projection data and the detector row conjugate projection data, and helically weighting the combined projection data using a combined helical weighting and conjugate data weighting algorithm such that a greater weight is applied to combined center row projection data than to at least one outermost detector row projection data.
