  		Figure 1. Primary transmission and scatter fraction results for the nine grids under two different scattering conditions (5 cm Perspex and 15 cm Perspex). Each line represents measurements for a given grid design (interspace material and strip density) with a different tube voltage: 80 kVp: dashed line, 100 kVp: dotted line, 120 kVp: solid line. The points on each line are the results for different grid ratios tested for a given grid design: {square}: 12:1, {Delta}: 10:1, x : 8:1, {blacklozenge}: 4:1.
