Some Suggestions for Transmission Tomography Based on the EM Algorithm
The standard reconstruction method in transmission tomography is convolution back-projection. The purpose of this work is to investigate the extent to which the quality of the reconstruction can be improved by taking into account the stochastic nature of the measurement process and the underlying regularity of the image. Some interim results are presented based on the EM algorithm.
