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.
The \ctsim package has two executable files: the graphical \helprefn{ctsim}{ctsim} and text \helprefn{ctsimtext}{ctsimtext} programs.

-\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.
-
-\ctsim can open projection files, image files, phantom definition files, and plotfiles.
-
-\usage

-\ctsimtext is a master shell for all of the command-line utilities.
-
-\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:
-
-\section{if1}\label{if1}\index{ctsimtext,if1}%

- \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.

-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}.
