Figure 2 :The ratio EDWFMFA/EDWFShift is plotted for Varian enhanced dynamic wedges using an 18 MV beam. For a 20x20 cm2 fi eld size, the difference in the total enhanced dynamic wedge factor calculated between the two methods is plotted for all locations heel and toe, where the point of calculation is shifted away from the center of the initial open fi eld
