FIGURE 1. Mean of reconstructed image replicates for OSEM and FBP with and without AC for 4 different slices (A, B, C, and D). Negatives in FBP images are not displayed. For every slice, FBP-AC and OSEM-AC images are displayed to 1 common maximum, as are FBP-NAC and OSEM-NAC images. Hot tumor images have been clipped for display. Last row contains corresponding reconstructed attenuation maps with lung, heart, and liver regions of interest (ROIs). Whereas columns A, B, and C are displayed in standard supine position, breast images in column D are displayed in prone position.
