Testing the Accuracy of Microstructure Reconstruction in Three Dimensions Using Phantoms

Abstract

Three-dimensional (3D) multi-region explicit geometric modeling of implicit images of polycrystalline materials microstructure is tested for accuracy and fitness using 3D Phantom geometries. Implicit data sets are generated from the explicit phantoms by sampling the phantoms over a range of resolutions from which explicit representations are then reconstructed. The reconstructed models are tested for error against the phantoms to characterize the accuracy of the reconstruction techniques as a function of resolution. The error of the reconstructed geometries decreases with increasing resolution. However the mean width of the reconstructed regions are consistently lower than the phantoms.
