Lamb Wave Tomography Combining Simulated Annealing and Simultaneous Iterative Reconstruction Technique

摘要：

According to the incomplete cross-hole projectionsin Lamb wave tomography,a new tomographic reconstructionmethod combining simulated annealing (SA) and simultaneousiterative reconstruction technique (SIRT) is developed in thispaper.In order to deal with the problem of incompleteconstraint,simulated annealing (SA) method in statistic physicsis introduced into the iteration of SIRT method.Based on theassumption of continuity among image pixels,constraint ofmost stable solution is added to get the optimal solution by SAmethod.The method is compared to the usual SIRT.Thesimulated reconstruction images and their cross-sectional slicesof the images for two different defects have been used for theevaluation.
