A new data reduction software package has been developed at CENBG for scanning transmission ion microscopy tomography (STIM-T) data. This program, TomoRebuild, has been designed in Visual C++® in the Windows® environment. Fortran 77® routines from the Donner Library were translated to C++ for the reconstruction of 2D and 3D data using the filtered backprojection algorithm. Tomography images are stored as ASCII files to be displayed using a graphic interface. A graphic software based on the AMIRA® environment was developed to extract and display 3D structures according to their density. The whole program was designed to be interactive, simple to use and easily adjustable to different experimental conditions. 3D STIM-T was carried out on microcomposite materials, allowing determination of the density of a thin AlN layer deposited on a SiC microfibre.
