+The fastest way to put \ctsim\ through it's basic operation is:
+\begin{enumerate}\itemsep=0pt
+\item \texttt{File - Create Phantom...} \\
+This creates a window with the geometric phantom. Choose the \texttt{Herman} head phantom.
+\item \texttt{Process - Rasterize...} \\
+This creates an image file of the phantom by converting it from a
+geometric definition into a rasterized image. You may use the defaults
+shown in the dialog box.
+\item \texttt{View - Auto...} \\
+Use this command on the new rasterized image window. This will optimize the intensity scale for
+viewing the soft-tissue details of the phantom. Select the \texttt{median} center and
+a standard deviation factor of \texttt{0.1}.
+\item \texttt{Process - Projections...} \\
+Use this command on the geometric phantom window. This simulates the collection of x-ray
+data. You may use the defaults shown in the dialog box. Additionally, you may wish to turn on
+\texttt{Trace - Projections} to watch to x-ray data being simulated.
+\item \texttt{Reconstruction - Filtered Backprojection...} \\
+Use this command on the projection window. This will reconstruct an image
+from the projections. Once again, you may use the defaults shown in the dialog box.
+\item \texttt{View - Auto...} \\
+Use this command on the new reconstructed image window. This will optimize the intensity scale for
+viewing the soft-tissue details of the reconstruction. Select the \texttt{median} center and
+a standard deviation factor of \texttt{0.1}.
+\item \texttt{Analyze - Compare Images...} \\
+Use this command on the rasterized phantom image window. This will bring up a dialog box
+asking for the comparison image. Select the reconstruction image that you just made and also select the "Make difference image"
+check box. You'll then see the image distance measurements and also a new window with the difference between the rasterized
+phantom and the reconstruction.
+\item \textbf{That's it!} You have just performed the basic operations with \ctsim. By varying the parameters of the rasterization,
+projection, and reconstructions you perform endless computed tomography experiments. \ctsim\ also has many other visualization
+and analysis features that you learn more about by reading the manual.
