Effect of MRAC-based errors. a Transversal and coronal views of the xMLAA-derived attenuation map for the HP experiment in the presence of an intentionally inserted air cavity in close vicinity of one of the earpads. Note, the air cavity is only present in the attenuation map and not in the phantom used during data acquisition. The right column gives the absolute difference to the original xMLAA-based attenuation map, obtained without insertion of the air cavity and shown in Fig. 6. b Transversal and coronal views of the xMLAA-derived attenuation map for the RF experiment after an intentional fat-water inversion. The right column gives the absolute difference to the original xMLAA-based attenuation map, obtained without fat-water inversion and shown in Fig. 8
