Abstract : CIT image reconstruction using information regarding shape of the electron density distribution in the plane of interested is implemented using a volumetric iterative technique. Shape estimation and guidance is provided on a localized basis both in the projection and image domains of the algebraic reconstruction process. Preliminary results of IRI-90 based simulations indicate substantial improvement in vertical resolution even for a priori sets which are very different from the test image.
