+Computed Tomography is a technique for estimating the interior of an object
+from measurement 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 the projections
+collected around the phantom object.

+\ctsim\ is the graphical shell for the CTSim project. It is
+written using the wxLibrary for cross-platform compatibility with GTK,
+Motif, and Microsoft Windows. It includes all of the functionality of
+the command-line tool {\tt ctsimtext} as well as image processing and visualization features.
+
+\section{Usage}
+ctsim [OPTIONS] [files to open...]
+
+\ctsim can open projection files, image files, phantom definition files, and plotfiles.
+
+\chapter{ctsimtext - The Command Line Interface}\index{ctsimtext}%
+\ctsimtext is a master shell for all of the command-line utilities.
+\setheader{{\it CHAPTER \thechapter}}{}{}{}{}{{\it CHAPTER \thechapter}}%
+\setfooter{\thepage}{}{}{}{}{\thepage}%
+
+\section{Usage}%
+
+\ctsimtext can be executed without any parameters. In that case, \ctsimtext
+offers a command-line to enter the function-names and their parameters. The output of the command is displayed. Further commands may be given to \ctsimtext. The shell is exited by the {\tt quit} command.
+
+\ctsimtext can also be called to execute a single command. This is especially useful for batch files containing multiple \ctsimtext commands. This is invoked by calling {\tt ctsimtext function-name parameters...}.
+
+The following function names are available:
+
+\subsection{if1}\index{Programs,ctsimtext,if1}%
+Perfoms math functions on a single image.
+
+\subsubsection{Usage}%
+\begin{itemize}\itemsep=0pt

+ \item equilinear
+ \end{itemize}
+
+ \item --nray
+ Number of samples per each detector
+
+ \item --rotangle
+ Sets the rotation amount as a multiple of pi. For parallel geometries use
+a rotation angle of 1 and for equilinear and equiangular geometries use a rotation angle of 2.
+
+ \item --field-of-view
+ Sets the field of view as a ratio of the diameter of the phantom. For parallel geometries, using a value of 1.0 is fine. For other geometies, this should be at least 1.3 to avoid artifacts.
+
+ \item --focal-length
+ Sets the distance of the radiation source and detectors from the center of the object as a ratio of the radius of the object. For parallel geometries, a value of 1.0 is fine. For other geometries, this should be at least 2.0 to avoid artifacts.
+\end{itemize}

+\section{Overview}\index{Web Interface,Overview}%
+The CGI program {\tt ctsim.cgi} takes projections of a standard
+phantom object, performs reconstruction, and then compares the
+rasterized phantom object with the reconstruction. The comparison is
+performed both visually by an image subtraction as well as by standard
+statistics as described by Herman\cite{HERMAN80}.
+

+ \item Perl (version 4.0 or higher)
+
+ \item A client web browser than can display PNG files. Most
