## Abstract ## Purpose To develop and implement a new approach for correcting the intensity inhomogeneity in magnetic resonance imaging (MRI) data. ## Materials and Methods The algorithm is based on the assumption that intensity inhomogeneity in MR data is multiplicative and smoothly varying. Us
More than a dozen Nuclear Magnetic Resonance (NMR) imaging methods have been described using different radio-frequency pulse sequences, magnetic field gradient variations, and data processing. In order to have a theoretical understanding in the most general case, we have conceived a computer program
A novel method to obtain separate fat and water images is presented. It is based on the replacement of the first echo generating pi pulse by two pi/2 pulses separated by a time delay corresponding to one-half cycle of the resonance frequency difference between fat and water protons.
