Fig. 4From: Triple modality image reconstruction of PET data using SPECT, PET, CT information increases lesion uptake in images of patients treated with radioembolization with \(^{90}Y\) micro-spheresComparison of PET images reconstructed with varying kernel parameter \(\sigma _p\). S1–S6 are the VOI for the spheres numbered from the smallest to the biggest. The plot shows increasing CoV and iteration number (1–30)Back to article page
