Validation of 4D Monte Carlo dose calculations using a programmable deformable lung phantom

4D dose calculation methods account for the effect of respiratory motion on the delivered dose by taking into account all three impacts of respiratory motion, including dose blurring, dose deformations and interplay effects [1,2]. In a 4D dose calculation algorithm, dose is calculated on multiple respiratory states of the anatomy and mapped to a reference anatomy by use of deformation vector fields (DVFs) to yield cumulative dose distributions. Different dose mapping algorithms such as dose interpolation mapping (DIM) [3], energy mass congruent mapping (EMCM) [4,5] and the voxel warping method (VWM) [6] have been developed.
