CT Image Reconstruction from Sparse Projections Using Adaptive TpV Regularization

<div>The comparison between reconstructed images using three different reconstruction algorithms and original Shepp-Logan phantom. (a) The horizontal profiles in reconstructed images using ART-TV, ART-TpV, and ART-ATpV methods from noise-free data and original Shepp-Logan phantom and (b) the horizontal profiles in reconstructed images using ART-TV, ART-TpV, and ART-ATpV methods from noisy data and original Shepp-Logan image.</div>
