METHOD FOR POST-PROCESSING MAGNETIC RESONANCE IMAGING IMAGES IN A CLINICAL CONTEXT

摘要

A method for post-processing images of a region of interest in a subject, the images being acquired with a magnetic resonance imaging technique, the method for post-processing comprising at least the step of:unwrapping the phase of each image,extracting a real signal over echo time for at least one pixel of the unwrapped images, andcalculating fat characterization parameters by using a fitting technique applied on a model,the model being a function which associates to a plurality of parameters each extracted real signal, the plurality of parameters comprising at least two fat characterization parameters and at least one parameter obtained by a measurement,the fitting technique being a non-linear least-square fitting technique using pseudo-random initial conditions.
