Foundations of MRI Phase Imaging and Processing for Quantitative Susceptibility Mapping (QSM)

Zeitschrift Fur Medizinische Physik, 2016
Quantitative Susceptibility Mapping (QSM) is a novel MRI based technique that relies on estimates of the magnetic field distribution in the tissue under examination. Several sophisticated data processing steps are required to extract the magnetic field distribution from raw MRI phase measurements.
