Computed tomography is a technique for estimating the interior of an
object from measurements of radiation collected around the object. This
radiation can be either projected through or emitted from the
object. \ctsim\ simulates the process of projecting X-rays
through a phantom object. \ctsim\ can then reconstruct the
interior of the object from those projections. \ctsim\ integrates
numerous visualization and analytic tools.

This manual begins with an introduction into the concepts of
\ctsim. Next, the graphical, command-line, and web shells are
presented. Finally, the installation of \ctsim\ is discussed.

I hope that you enjoy \ctsim!
