Emission Expectation Maximization Look-Alike Algorithms for X-Ray CT and Other Applications

PURPOSE: In emission tomography, the EM (expectation maximization) algorithm is easy to use with only one parameter to adjust — the number of iterations. On the other hand, the EM algorithms for transmission tomography are not so user-friendly and have many problems. This paper develops a new transm...
