Abstract: | There are many reconstruction algorithms for tomography, raft for short, and some of them are considered “classic” by researchers. The so-called raft library, provide a set of useful and basic tools, usually needed in many inverse problems that are related to medical imaging. The subroutines in raft are free software and written in C language; portable to any system with a working C compiler. This paper presents source codes written according to raft routines, applied to a new imaging modality called X-ray fluorescence tomography.Program summaryProgram title: raftCatalogue identifier: AEJY_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEJY_v1_0.htmlProgram obtainable from: CPC Program Library, Queen?s University, Belfast, N.

| raft-fun: gengetopt – http://www.gnu.org/software/gengetopt/gengetopt.htmlNature of problem: Reconstruction algorithms for tomography, specially in X-ray fluorescence tomography.Solution method: As a library, raft covers the standard reconstruction algorithms like filtered backprojection, Novikov?s inversion, Hogan?s formula, among others. The input data set is represented by a complete sinogram covering a determined angular range. Users are allowed to set solid angle range for fluorescence emission at each algorithm.Running time: 1 second to 15 minutes, depending on the data size. |
