Software for a X Ray Tomograph
Rosario Martínez Gómez, Israel Vite Silva, Luis Gerardo de la Fraga · Research in Computing Science · 2006
A software tool-box has been developed, which allows, not only the volume reconstruction from X ray tomography images, but also the visualization of reconstructed isosurfaces. Although it may be considered that the software needed is tightly linked to the hardware, we’ll prove that we need five different (hardware independent) software components for the whole process: (1) acquisition, (2) projection’s centering, (3) reconstruction, (4) isosurfaces segmentation and (5) visualization. The reconstruction component was taken from Xmipp, an old software for 3D reconstruction of biological macromolecules, segmentation was developed using k-means algorithm and the visualization was built using the splatting technique. In addition we compare splatting with another two surface visualization techniques such as simple voxels and deformable simplex meshes. The most of the software components were developed in C, C++ and perl. The graphical user interface for the visualization component was developed in C++ using Qt and OpenGL libraries
