Fig. 2From: Calibration and evaluation of the relative biological effectiveness for carbon-ion radiotherapy in a new relative to a clinically applied treatment planning systemRBE-weighted (DRBE-Ray) and absorbed (Dabs-Ray) DDDs at the central axis of the calibration plans after calibrations and the corresponding RBE-weighed (DRBE-Syngo) and absorbed (Dabs-Syngo) DDDs from Syngo. Local differences are also displayed in the figures. Absorbed DDDs before calibration (Dabs-not Cal) in the left panel are shown for comparisons. The centers of targets of (a–c) are 4.0, 10.0, and 15.0 cm from the surface of WPs, respectivelyBack to article page
