The incorrect version of figure 3 has been published in article Francescon et al (2017). The correct figure is shown below:
Figure 3. MC calculated correction factors for OAR measurement kΩ(r, z, f, 0, z, f ), simplified to kΩ in the figure, as a function of off-axis distance along the x-axis for rectangular MLC fields at 800 mm SSD. Data is shown for the 7.6 mm × 7.7 mm field at (a) 15 mm depth and (c) 300 mm, and for the 115 mm × 100 mm field at (b) 15 mm depth and (d) 300 mm. The dashed vertical line shows the geometric field edge. The inset shows the two orientations used for Edge detector calculations, with the top surface long axis parallel to scan direction (top) and perpendicular (bottom).
