A tissue characterization with
susceptibility e.g., susceptibility weighted imaging (SWI), quantitative
susceptibility mapping (QSM), susceptibility tensor imaging (STI), gets more
attention in high field MRI. Using a numerical phantom, various processing
elements for QSM are analyzed. We propose a method to remove background phase
using a discrete wavelet transform (DWT). The proposed DWT method shows
superb performances over exiting techniques including SHARP in the QSM
experiments with volunteer subjects at 7.0T and 3.0T MRI, without distortions
at the susceptibility maps.
