There are a variety of readily available and popular methods for resampling (or reconstructing) MR data. They are not all equally effective. The major distinction is whether or not they conserve the information in the image. There are two primary issues that we have addressed. One is selection of an appropriate or optimal method and the second is the proper implementation of the method, because the failure to conserve information could stem from either issue.

In the final section of this chapter we considered some issues specific to resampling data in a 3D sense and suggested the use of spectral tapering in conjunction with optimal interpolation.
