Abstract
Abstract The measurement of three dimensional displacement fields from tomo-graphic image registration, or Digital Volume Correlation, usually operates over two volumes that have been reconstructed from numerous radiographs at the elementary voxel scale. It is shown herein that a single “reference ” (i.e., fully reconstructed) volume, and very few radiographs of the deformed configuration may be sufficient to evaluate 3D displacement fields. The proposed algorithm can reduce the needed num-ber of projection data by several orders of magnitude as shown on an experimental data set.
