Figure 4From: Dose-volume constrained optimization in intensity-modulated radiation therapy treatment planning Time course showing variation of Q . (a) \((\mathrm{PTV}, 82.1, 0.87)\), (b) \((\mathrm{PTV}, 95.9, 0.98)\), (c) \((\mathrm{OAR}1, 30, 0.9)\), (d) \((\mathrm{OAR}2, 20, 0.4)\), (e) \((\mathrm{OAR}3, 20, 0.6)\), and (f) \((\mathrm{OAR4}, 30, 0.9)\). Values of 0 and 1 indicate states of being partly acceptable and not acceptable, respectively.Back to article page
