Fig. 2From: Quantitative susceptibility mapping (QSM) of the cardiovascular system: challenges and perspectivesSteps of quantitative susceptibility mapping (QSM) post-processing. Example left ventricular QSM maps were computed from magnitude and phase multi-echo gradient echo images. Step 1: Phase images are phase unwrapped. Step 2: The local and background fields are separated, using segmentation masks generated from the magnitude images. Step 3: The QSM map is computed from the local magnetic field mapBack to article page
