1. A method, comprising: computing a scaling value as a function of the projection data that is received from a CT scanner; scaling a regularization term of an update algorithm of an iterative reconstruction algorithm with regularization with the scaling value, wherein the scaling value is variable in at least one dimension, thereby varying the regularization of the iterative reconstruction in the least one dimension; iteratively reconstructing an image based at least on the update algorithm, the varying scaled regularization term, and the projection data; wherein the computing, the scaling and the iteratively reconstructing are performed using one or more configured processors.
