title: Internally iterative improvement of optical tomographic reconstructions.
abstract: An iterative improvement of minimum-norm least-squares estimates for values in limited-angle reconstruction is presented. Implementation provides considerable improvement over noniterative methods for reconstructions with total angles less than 90 degrees with redundant data and requires considerably less computation time than do globally iterative schemes.
