Figure 4.

Volume of distribution (V_T) derived from normalization and attenuation-weighted ordered subsets expectation maximization (NAW-OSEM)-G5 (A, D), NAW-OSEM (B, E), and partial volume correction (PVC)-NAW-OSEM (C, F) reconstructions of HR+ data compared with V_T derived from ordinary Poisson OSEM (OP-OSEM)-G6 (top row) or standard OP-OSEM reconstructions (bottom row) of high resolution research tomograph (HRRT) data. Each colored symbol represents a single subject and the same symbol per subject represents different anatomical regions. The dashed line is the line of identity.
