+The parameters are \texttt{xsize}, \texttt{ysize}, and \texttt{interpolation}.
+The \texttt{xsize} and \texttt{ysize} parameters set the size of the 
+resulting image file. The \texttt{interpolation} parameter selects the
+interpolation method. Currently, the \texttt{bilinear} option provides
+the highest quality interpolation.
+
+\subsection{Process - Convert FFT Polar Dialog}
+The paramters for this option are the same as 
+\helprefn{convertpolardialog}{Convert Polar Dialog}. For this command,
+though, the projections are Fourier transformed prior to conversion to
+polar image.
+
+\subsection{Reconstruct - Filtered Backprojection Dialog}
+This dialog sets the parameters for reconstructing an image from projections
+using the Filtered Backprojection technique. The parameters are identical
+to those for the \helprefn{pjrec}{pjrec} program.
