Maximum activity in the phantom experiment. Panel A depicts the maximum activity measured in the 5 sources in the scam and prosthesis experiments using MAR CT (orange symbols) or conventional CT (black symbols) for attenuation correction. Panel B gives the percentual differences between the measurements and the reference value (in the scam experiment without MAR), panel C the differences between MAR and nonMAR PET. Panel D indicates the percentage of the error in the prosthesis experiment that is recovered by MAR. lat_acet lateral acetabular source; med_acet medial acetabular source; lat_neck lateral neck source; med_neck medial neck source; troch trochanteric source
