Clinton DeW. Van Siclen
TL;DR
This paper introduces an iterative image reconstruction method that incorporates additional constraints beyond radiation measurements, offering a comparison with the established MLEM algorithm.
Contribution
The paper presents a novel iterative reconstruction technique that integrates external constraints, enhancing image quality over traditional methods like MLEM.
Findings
The new method effectively incorporates non-measurement constraints.
Comparison shows advantages over MLEM in certain scenarios.
Improved image reconstruction accuracy.
Abstract
An iterative method is derived for image reconstruction. Among other attributes, this method allows constraints unrelated to the radiation measurements to be incorporated into the reconstructed image. A comparison is made with the widely used Maximum-Likelihood Expectation-Maximization (MLEM) algorithm.
