Fig. 2

Dual-isotope SPECT reconstructions (166Ho in green, 99mTc in blue) fused with the accompanying CT images (grayscale). a Anthropomorphic torso phantom with the 1200-ml liver compartment filled with a 34-kBq/ml 99mTc solution. A 130-ml insert, filled with a 0.4-MBq/ml 166Ho solution, was placed inside of the liver compartment. The remaining volume of the phantom was filled with water. b NEMA image quality phantom, background filled with an 11-kBq/ml 99mTc activity concentration. The spheres were filled with a 0.8-MBq/ml 166Ho solution
