Fig. 3From: Variability in PET image quality and quantification measured with a permanently filled 68Ge-phantom: a multi-center studyRCmax (a–d), RCmean (e–h) and RCpeak (i–l) computed from the hot spheres with the diameter of 10–37 mm using routine protocols with PSF correction (a, e, i) and the corresponding AVIs (b, f, j) and standard protocols (c, g, k) and the AVIs (d, h, l). Protocols 6r and 6s were excluded. The upper and lower limits of EARL2 are also shown in the imagesBack to article page
