  • Abstract
    Figure 2 shows reconstructed images of a two-chamber phantom (filled with two activity concentrations) which was measured in 7 different positions. The applied motion of the phantom induces a significant image degradation (left). Motion parameters were extracted from EPI volumes to correct the emission data before the reconstruction with PRESTO. The blurring due to motion completely vanishes (right).
