Figure 2.
Coronal views of simulations of cardiac PET/CT study. The attenuation images (row 1) provided attenuation correction for the PET images (row 2) simulated with 2.5×107 events (roughly 1/4 typical number of events). Column (a) contains true attenuation correction. Column (b) contains mismatched attenuation correction that was aligned with the proposed method to generate results in column (c) containing reduced artifacts. The attenuation maps have matched colormaps and the PET images have matched colormaps.
