Regularized reconstruction in quantitative SPECT using CT side information from hybrid imaging
A penalized-likelihood (PL) SPECT reconstruction method using a modified regularizer that accounts for anatomical boundary side information was implemented to achieve accurate estimates of both the total target activity and the activity distribution within targets. In both simulations and experiment...
