Fig. 6From: Towards standardization of absolute SPECT/CT quantification: a multi-center and multi-vendor phantom studyRC per sphere diameter for (a) small phantom (BMI, 25 kg/m2), (b) medium phantom (BMI, 28 kg/m2), (c) large phantom (BMI, 47 kg/m2), (d–e) RCmean and RCmax for all three phantom volumes (median only). All data was reconstructed using a vendor-neutral algorithmBack to article page
