Fig. 4From: 166Holmium–99mTechnetium dual-isotope imaging: scatter compensation and automatic healthy-liver segmentation for 166Holmium radioembolization dosimetryAxial view of 99mTc reconstructions and healthy-liver segmentations. Healthy-liver segmentations of 99mTc SPECT/CTs, acquired in presence of 250 MBq166Ho (top panel) and without 166Ho (bottom panel). Three 99mTc activity levels are presented to indicate the effect on image quality and segmentation accuracyBack to article page
