In this work, we proposed a simplified implementation of the total variation minimization iterative reconstruction algorithm for the conventional x-ray CT application, which was originally developed by the University of Chicago group. The simplifications make it possible for completely parallel computation that is suitable to be implemented with a GPU board. Reconstructed images from mathematical and real phantoms are demonstrated to verify the validity of our simplified algorithm.
