L0 constrained sparse reconstruction for multi-slice helical CT reconstruction
In this paper, we present a Bayesian maximum a posteriori (MAP) method for multi-slice helical CT reconstruction based on a L0-norm prior. It makes use of a very low number of projections. A set of surrogate potential functions is used to successively approximate the L0-norm function while generatin...
