14 September 1993 Optimal metric for factor analysis of medical image sequences

Abstract
A new statistical approach for Factor Analysis of Medical Image Sequences (FAMIS) is proposed. It leads to the optimal metric to be used in the orthogonal and oblique analysis steps of FAMIS. It is shown that this metric depends on the statistical model related to the image acquisition process and we derived its expression for nuclear medicine and magnetic resonance imaging. A scintigraphic dynamic study illustrates the method. We discuss the normalization induced by this optimal metric in comparison with other normalizations.
