Fig. 7From: NEMA image quality phantom measurements and attenuation correction in integrated PET/MR hybrid imagingThe signal-to-noise ratio (SNR) calculated for different reconstruction parameter combinations for the four active spheres: 10 mm (a), 13 mm (b), 17 mm (c) and 22 mm (d). The values represent the mean of four independent NEMA IQ measurements using CT-based ACBack to article page
