Dose Course 2018_Flipping book

Learning objectives

1. Review aspects of beam modelling on treatment planning systems (TPS) that play major role on the calculation of dose in plans comprising of small MV photon beams: • finite size of beam source (also referred to as focal spot ) • jaw and MLC leaf edges • resolution: influence of voxels size (calculation grid) • Inhomogeneities

2. Discuss examples of implementations on modern TPSs
