Schematic plot of the 4D-interplay dose simulator: Inputs are the IMPT plan which contains the spot positions and weights, 4DCT, deformation vectors of 4D phase to the reference phase (T50 in our simulation), and breathing pattern (either regular or realistic pattern from RPM). Output is the 4D dynamic dose distribution.
