Efficient binary reconstruction for non destructive evaluation using gammagraphy

Résumé

The localization and the sizing of 3D flaws within a homogeneous metallic media is a major task for non destructive evaluation (NDE). This paper adresses the problem of the reconstruction of such flaws using an efficient binary algorithm. Basically, the method rests on the fact that a simple binary constraint suffices for an accurate and robust reconstructions in the context of NDE. A heuristic minimization, computationally attractive, is designed in order to provide fast reconstructions. The proposed algorithm is compared with standard binary (the iterated conditional mode algorithm) and non binary (penalized approach with convex potentials Gibbs random fields) reconstruction techniques.
