%X Recently,there are many practical applications of tomographic reconstruction that consist of minimizing the sum of a residual energy and image total variation(TV).In this paper,we develop an uncoupled iterative algorithm for solving the recent popular TV-regularized CT optimization problem.Using surrogate function,we split the sum minimization scheme to the minimizing weighted least square function and TV denoising with weighted norm iteratively.In order to find the stable solution of this model,we use Cham...
