Abstract

Affine transformations of volume arrays are important for implementing volume modeling and orthographic viewing transformations and for registering multiple data sets. In this paper we extend the two-pass algorithm for affine image transformations to a three-pass affine volume transformation algorithm. The mathematics of the decomposition is derived and the issues involved in resampling the transformed volume are discussed.
