Algorithms for limited-view computed tomography: an annotated bibliography and a challenge.

Rangaraj M. Rangayyan, +2 more
- 01 Dec 1985 - 
TL;DR: An overview of techniques proposed to tackle the problem of limited-view computed tomography, employing diverse theories such as signal recovery, image restoration, constrained deconvolution, and constrained optimization, as well as novel schemes such as iterative object-dependent algorithms incorporating a priori knowledge and use of multispectral radiation are presented.

A Natural Pixel Decomposition for Two-Dimensional Image Reconstruction

Michael H. Byonocore, +2 more
- 01 Feb 1981 - 
TL;DR: In two-dimensional image reconstruction from line integrals using maximum likelihood, Bayesian, or minimum variance algorithms, the x-y plane on which the object estimate is defined is decomposed into nonoverlapping regions, or "pixels".

A Maximum Likelihood Approach to Transmission Image Reconstruction from Projections

A. J. Rockmore, +1 more
- 01 Jun 1977 - 
TL;DR: In this paper, the joint probability density function of the projections was used to derive the reconstruction scheme which is optimum in the maximum likelihood sense, and it was shown that for an average number of counts detected in excess of approximately 100 per projection, the image is essentially unbiased.

Penalized Weighted Least-Squares ImageReconstruction for Positron Emission Tomography

Jeffrey A. Fessler
TL;DR: Qualitative results suggest that the streak artifacts common to the FBP method are nearly eliminated by the PWLS+SOR method, and indicate that the proposed method for weighting the measurements is a significant factor in the improvement over FBP.
