Figure 8

Resolution uniformity study for both central plane (X = 0) and off-center plane (X = 1.5 cm) is shown for (a) in-plane (parallel to panels) and (b) orthogonal-plane (perpendicular to panels) reconstructed image slices. DOI resolution is set to be 2 mm and the panel separation is 4 cm. Within inherent error, the system achieves very uniform in-plane and orthogonal-plane resolutions. However, a dependence of in-plane resolution on the off-center distance (X value) is observed. In the in-plane slices this dependence is most noticeable for the smaller sphere sizes. The definition of row index is shown in figure 6.
