Image reconstruction software for computed tomography (CT)

The project

I started this work within my Ph.D. project at Nikhef, Amsterdam (www.nikhef.nl). The software is fully based on C++ and is currently being developed and updated by me and John Idarraga (Nikhef, Amsterdam). ROOT scripts (https://root.cern.ch/drupal/) are also provided for data visualization.

Download

The source codes can be downloaded from SVN at the following repository: https://svnweb.cern.ch/cern/wsvn/ctreco. To checkout from a Linux terminal, just type the following command: svn co svn+ssh://@svn.cern.ch/reps/ctreco where is your CERN login name

Runnig the software

Please refer to the README.txt file. There each piece of code is explained in detail.

Prerequisites

To compile the code you just need the standard GNU gcc compiler under Linux, plus the FFTW libraries (http://www.fftw.org/) for the computation of the fast Fourier transform in the FilteredBackprojection (FBP) reconstruction algorithm.

Hands on! The demo

For a first hands-on exercise to familiarize with the code, run the demonstration from the demo/ subfolder. Please refer to the DEMO.txt file for detailed instructions on how to proceed.

The algorithms

Two reconstruction algorithms are implemented:

More on this project

This work was originally developed for studying the potentiality of Medipix-based (http://medipix.web.cern.ch/medipix/) semiconductor detectors for X-ray imaging applications. The project is fully described in my Ph.D. thesis: "The Color of X-rays. Spectral X-ray computed tomography using energy sensitive pixel detectors".

The manuscript can be freely downloaded from one of the following websites:
