In this work we present phantom validation of QSMs
ability to distinguish between solid and hollow spheres
of susceptibility. Since these geometries give rise to
similar field patterns, they can be technically
challenging to reconstruct. They are present in MS
lesions and hemorrhage, among other conditions, and are
thus clinically important to investigate.
