FORMATION OF MAGNETIC RESONANCE IMAGES USING MULTIPLE-POINT DIXON METHOD

摘要

FIELD: physics.SUBSTANCE: invention can be used for generation of magnetic resonance (MR) image. Method comprises steps of: subjecting a portion of body to a calibration sequence comprising radio-frequency pulses and switched magnetic field gradients controlled in such a manner that a calibration signal data set is acquired by means of a multi-point Dixon technique at a first image resolution; deriving calibration parameters from calibration signal data set; subjecting portion of body to an imaging sequence comprising radio-frequency pulses and switched magnetic field gradients controlled in such a manner that a diagnostic signal data set is acquired at a second image resolution which is higher than the first image resolution; and reconstructing a diagnostic MR image from diagnostic signal data set, wherein MR device is operated according to derived calibration parameters during acquisition of diagnostic signal data set and/or during reconstruction of diagnostic MR image.EFFECT: high image quality.10 cl, 3 dwg
