Fig. 7From: Performance assessment of the 2 γpositronium imaging with the total-body PET scannersLeft: Comparison between generated positronium mean lifetime and reconstructed one assuming different detector CRT resolutions as a function of NEMA position number (see Table 1). Differences between obtained results are in the order of \(\mathcal {O}\)(10 ps). Right: Resolution of the mean lifetime determination as a function of detected entries in a single voxelBack to article page
