GSECARS Tomography Processing Software

This document describes the IDL software used for reconstructing and viewing tomography data at CARS. All of these IDL routines are available in a tar file.  The reconstruction is normally done using the GridRec reconstruction code, which is written in C.  The GridRec code is also available in another tar file.

The normal user interface for this software is through the IDL GUI routine tomo_display.  The following screen shot shows the tomo_display interface.

We have broken the tomography data processing down into 3 steps


The preprocessing routine performs the following steps:


The reconstruction routine performs the following steps:


The standard IDL procedures TV and TVSCL are very useful for displaying 2-D data. IDL's SLICER3 procedure is good for displaying 3-D data. In addition there is set of GSECARS-developed routines for visualizing 2-D and 3-D tomography (or other) data.
