Claim:
1. A computer-implemented method for determining an accuracy of a reconstructed dataset relative to a reference dataset comprising: decomposing, by a processor device, a reference dataset into a plurality of orthogonal basis functions; reconstructing a dataset using said plurality of orthogonal basis functions; determining differences between the reference dataset and reconstructed dataset, using statistical parametric mapping (SPM) to quantify, at said processor device, existence of statistically significant regions of excursion in the determined differences between the reference dataset and reconstructed dataset; determining, based on said quantified statistically significant regions of excursion, a minimum number of orthogonal basis functions to reconstruct the dataset with a specified degree of accuracy; and storing said minimum number of orthogonal basis functions as representative of said reference dataset.
