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.
-\rtfsp\ctsim\ simulates the process of projecting X-rays through a phantom object.
-\rtfsp\ctsim\ can then reconstruct the interior of the object from the projections

+\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.

+\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...}.
