Fig. 1 — a The NEMA IQ phantom. b MR imaging (in-phase image) of the NEMA IQ phantom using the MR AC Dixon VIBE sequence showing only fluid phantom filling (water). The phantom housing (Plexiglas) is not visible in MR imaging and thus, also not considered in the MR-based μ-map of the phantom (c). Note that the glass spheres are displayed as signal voids (dark rims in b) that are segmented as water in the MR-based μ-map (c)
