MRI Phantom Imaging Protocols

A homogeneous phantom was designed to mimic cerebrospinal fluid and opacified blood vessels, while a heterogeneous phantom was designed to mimic the brain white matter. Both the homogeneous and heterogeneous phantoms were scanned by two clinical MRI scans (Optima MR450w 1.5T and Discovery MR750w 3T, both from GE Healthcare, Milwaukee, WI, USA), with different FOVs (24, 18, and 12 cm) and different matrices ( $256\times 256$ , $256\times 128$ , and $128\times 128$ pixels). Only T1 clinical sequences were considered. More details about the image acquisition devices and protocols can be found in paper [12 (link)] by Ammari et al. who studied the same phantom dataset.
