Abstract
Restoration of the original image from data available in restricted regions has been the subject of many studies in the field of optical, X-ray and acoustical imagings. Several concrete means for extrapolating of the observed data beyond the observed region have been proposed.1-5 Among them, iterative means for the image restoration is considered as one of the most effective methods, because of its stability even under faily noisy observed data.
