Abstract

This paper introduces a method for incorporation of volumetric a priori information into a limited angle tomographic image reconstruction process, such as that encountered in computerized ionospheric tomography (CIT). Data-dependent localized volumetric correction in projection and image domains is provided by the iterative inversion algorithm for enhanced reconstruction of two and three dimensional images of ionospheric electron density
