TV-Regularized Sparse-View CT Reconstruction
============================================
TV-Regularized Sparse-View CT Reconstruction (ASTRA Projector)
==============================================================
This example demonstrates solution of a sparse-view CT reconstruction
problem with isotropic total variation (TV) regularization

where $A$ is the X-ray transform (the CT forward projection operator),
$\mathbf{y}$ is the sinogram, $C$ is a 2D finite difference operator, and
$\mathbf{x}$ is the desired image.
$\mathbf{x}$ is the desired image. This example uses the CT projector
provided by the astra package, while the companion
[example script](ct_tv_admm.rst) uses the projector integrated into
scico.
