Purpose
To develop a robust algorithm for field‐mapping in the presence of water–fat components, large field inhomogeneities and MR signal voids and to apply the developed method in body applications of quantitative susceptibility mapping (QSM).
Methods
A framework solving the cost‐function of the water–fat separation problem in a single‐min‐cut graph‐cut based on the variable‐layer graph construction...
Purpose
To develop a method for improved B0 field‐map estimation, deblurring, and image combination for multispectral imaging near metal.
Methods
A goodness‐of‐fit field‐map estimation technique is proposed that uses only the multispectral imaging (MSI) data to estimate the field map. Using the improved field map, a novel deblurring technique is proposed that also employs a new image combination...
