Figure 3
Details of reconstructed slices corresponding to the central portion and to the edge of the vertical field-of-view obtained with a conventional planar filtration system [(a) edge, (b) center] and with the flattening filter [(c) edge, (d) center], respectively. (e) Plot of SNR as a function of slice position measured within the dashed circles in (a)–(d) for both filtering configurations. Light-blue dashed lines represent slice positions of panels (a)–(d). |
