Figure 1: — Integration of a commercially available treatment planning system and a general-purpose optimization system for 4D optimization for respiratory phase-dependent IMRT treatment planning. D_i = a 3D dose distribution of the phase i treatment plan; D = a 4D dose distribution to be delivered obtained from a deformable dose-summed 4D treatment plan; L = an MLC leaf sequence as a function of monitor units and respiratory phase; f = an objective function of optimization; MU = monitor units; θ = a respiratory phase; v_max = the maximum MLC leaf velocity.
