RMSE curves of NCAT phantom reconstructions by SART algorithm, TVM algorithm and our algorithm for one typical phase of the NCAT phantom.

Abstract

<p>The graphs on top row and bottom row present the RMSE curves of the results reconstructed from noise-free projection dataset and noisy projection dataset respectively. The graphs from left to right in each row present the RMSE curves of the results reconstructed from scanning angular ranges [0, 90°] and [0, 120°], respectively.</p
