+CTSim simulates the process of collecting tomographic X-ray data of

+projections. CTSim reconstructs the original phantom image from the
+projections using a variety of algorithms.

HISTORY
=======
CTSim development began in 1983 while I was in medical school. It was
-written using Lattice C and MS-DOS. I used assembly language to write
+written using Lattice C and MS-DOS. I used 8086 assembly language to
+code convolution and backprojection routes and also to write graphics
directly to an IBM EGA video adapter.
In 1999, I ported CTsim to GNU/Linux. In April 2000, the source code
In June 2000, entire code for revised and converted to C++.

-The official home for CTsim is http://www.ctsim.org. From this site,
-you can download the CTsim source code and use CTSim online using a
-beowulf cluster.
+WHERE
+=====
-I would be very pleased to have other developers join me in the
-development of CTSim. Please see the TODO list for the most obvious
-ideas.

-OVERVIEW
+FEATURES
========
-CTSim simulates the collection of x-rays by a CT scanner. These x-rays
-of objects are called projections.
-
-Phantom objects are defined. Several built-in phantoms are included,
-as well as an extension to load files of phantom definitions.
+Several standard phantom objects are built-in. Other phantoms can be
+loaded from ASCII files.
CTsim uses cross-platform compatible file formats for projection data and
image data.
as described in the INSTALL file.
