Recorded 166Ho–99mTc spectra. Spectra recorded by the SPECT scanner of an anthropomorphic phantom filled with 166Ho and 99mTc. Curves are depicted for 166Ho:99mTc activity combinations (in MBq) of: 282:0 (solid line), 268:25 (dashed line), and 250:125 (dotted line). The curves were scaled such that the tails of the spectra overlap for visual comparison. The relative difference between the spectra is attributed to 99mTc. Orange and blue areas represent the 166Ho and 99mTc photopeak windows, respectively, while the gray areas depict the scatter windows (see Table 2)
