Abstract
This paper presents a new and comprehensive approach for correcting magnetic-resonance images that are subject to three-dimensional geometric distortion. Distortion in such images is typically caused by variations in the magnetic- field gradient in each of the three spatial dimensions. The new approach sequentially applies one-dimensional and two- dimensional correction techniques to achieve a complete three-dimensional geometric correction. It thus avoids many theoretical complications and computational inefficiencies that are inherently associated with direct (non-sequential) three-dimensional correction techniques.
