Figure 5From: Intra-fraction setup variability: IR optical localization vs. X-ray imaging in a hypofractionated patient population6 dof corrective parameters. Frequency distribution plots of the linear (Tx, Ty, Tz) and angular deviations (Ax, Ay, Az) resulting from kV X-ray images and DRR matching after irradiation. Bars are centered on labels and ranges over a 0.5 mm interval.Back to article page
