Abstract
An analysis of a chemical-shift-sensitive NMR imaging technique using adjusted phase encoding and signal separation by solving systems of equations is given. A procedure for choosing the chemical-shift phase-encoding times for a given spectrum of the object to be imaged is described. This leads to a minimization of the influence of noise on the signal separation, enabling short encoding times which are advantageous in case of short T 2 relaxation times, strong spin-spin couplings, or considerable B 0 inhomogeneities. Examples using simulated as well as experimental data derived from 19F NMR imaging are given.
