DOI: 10.1002/mrm.29260
Abstract: Homodyne filtering is a standard preprocessing step in the estimation of SWI. Unfortunately, SWI is not quantitative, and QSM cannot be accurately estimated from filtered phase images. Compared with gradient‐echo sequences suitable for computing QSM,… read more here.

DOI: 10.1364/ol.42.002062
Abstract: Phase images measured in the radio frequency (RF) and optical frequency (OF) ranges, whose difference was about 4×105, were combined on the basis of a pattern matching method. RF phase imaging was implemented with an… read more here.
