Fraction-variant beam orientation optimization for non-coplanar IMRT
, 2017 Conventional beam orientation optimization (BOO) algorithms for IMRT assume that the same set of beam angles is used for all treatment fractions. In this paper we present a BOO formulation based on group sparsity that simultaneously optimizes non ...
