A method for correcting motion artifacts within a volumetric data set is
provided. The method includes obtaining a volumetric data set containing
spatial and temporal information regarding an object. The volumetric data
set is organized into data slices such that at least two adjacent data
slices are representative of a common physical slice within the object at
different points in time. The relative motion between adjacent data
slices in determined for the slices of the volumetric data set and used
to correct for the relative motion between said adjacent slices.
