Magnetic resonance imaging (MRI) is a tomographic imaging technique based on the well-known nuclear magnetic resonance (NMR) phenomenon first observed in bulk materials independently by Edward Purcell’s group at Harvard [1] and Felix Bloch’s group at Stanford in 1946 [2]. The fundamental MRI concept was proposed by Paul Lauterbur in 1972 [3]. Since then, MRI has developed into a premier tool for imaging objects and, specifically, for imaging the human body in vivo [4]. MRI experiments are generally designed in a way to collect data that represent the Fourier transform of the object being imaged. This means that any method developed for improved image reconstruction and processing in any other field such as optics or astronomy, for example, could be used here as well. Likewise, new concepts introduced through advances in MRI may have applications to these other fields. For more information about the basics of MR and related reconstruction issues, we refer the reader to three recent texts in the field [5-7]. This article deals with current image reconstruction and processing issues in MRI for the study of tissue structure and function. In image reconstruction, we discuss the need for new algorithms that can produce high-resolution images with good signal-to-noise ratio from reduced amounts of data. In image processing, we describe outstanding problems in automatic image registration and segmentation.
