The MVT Toolbox provides researchers in the many tomography fields with a collection of generic tools for solving linear and non-linear forward modeling problems. The toolbox is made up of two parts:

• fddlib: a C++ Frequency-Domain Diffusion library;
• mvtlab: a collection of MATLAB utilities for solving linear diffuse optical tomography problems and providing a framework for additional user-defined functionality.

fddlib: The Frequency-Domain Diffusion Library

Features

• designed for flexibility in establishing parameters providing the ability to tailor the tool to specific tomography problem domains;
• handles 2- and 3-dimensional problem configurations;
• solvers for DOT, ERT, EM, and PT tomography domains provided;
• text-based user-specified problem instances can be constructed in any editor (e.g. emacs, vi, notepad) using a defined tagging format;
• front-end parser for the tagged data files;
• Doxygen-generated documentation in pdf and html formats

Requirements

• Version 1.2a of IML++, the Iterative Methods Library;
• The GNU C++ compiler version 2.95 or higher
  
• GNU Make utility
  

The fddlib software was developed and tested under Redhat Linux. The software also runs under UNIX.  The source code is provided, and has been developed so as to compile successfully with any C++ compiler.  IML++ is also available in source code form.  However, as no testing of the software was done other than under Redhat Linux, that is the recommended operating environment.

Coming Attractions
We are currently working on a MATLAB-based GUI front end for fddlib to simplify the process of specifying problem instances.

mvtlab: MVT MATLAB Utilities

The MATLAB utilities currently include support for linear diffuse optical tomography problems using a born-1 forward solver and were developed for use in undergraduate engineering courses introducing students to the field of tomography.  However, the software was designed to allow for additional functionality to easily be added, including additional solvers, reconstruction methods, and tomographic methods.  The utilities make use of object-oriented programming constructs now available in MATLAB to enhance the ease with which functionality can be added and extended.

Requirements

• MATLAB Version 6, Release 13 or higher
