Abstract
The reconstructed residual error was recently introduced as a localized measure of the accuracy of a segmented tomogram. In this paper, we use the reconstructed residual error during the reco nstruction , and adapt the recently proposed Discrete Algebraic Reconstruction Technique ( DART ) to only enforce discreteness in regions where this is appropriate. Simulation experiments show that the reconstructed residual error can detect non - homogeneous regions . Based on this observation, the DART algorithm is modified to allow the reconstruction of objects that are only partially discrete . The experiments show that the reconstruction quality of both homogeneous and non - homogeneous region s is improved.
