Abstract :
The authors present minimum distance methods for reconstructing transmission tomography images. Specifically, the methods the authors propose estimate the attenuation density by minimizing least-squares (weighted and unweighted) and Kullback-Leibler distances. The algorithms are compared using a simulated phantom and Poisson data
