- It is interesting to note the origin of the
appellation of this statistical method. It is of course taken from Greek
mythology. Procrustes is the villainous son of Poseidon who forced
travelers to fit into his bed by stretching their bodies or cutting off
their legs. He was killed by Theseus who delivered to him the same
punishment he had meted out to his victims.

- The resulting
errors are obviously more tedious to quantify in terms of physical
units (i.e. mm) if the pixel calibration errors are large, requiring
inclusion in quadrature [Bev69], but the errors in the determination of
voxel dimensions are usually negligible in practice and are so
treated for simplicity.

- The correct registration
transformations are actually known from the generation of the random
transformations to simulate the uncorrelated orientation which requires
registration. This method of storing the correct registration transformation
was chosen for ease of coding the simulation and greater conceptual
similarity to the study based on real scans.
