Abstract: A method of radiotherapy treatment planning for particle-based arc treatment comprises the steps of



determining (S11; S21) an initial set of candidate energy layers,
performing a calculation on the initial set,
determining (S13; S23), based on the outcome of said calculation, at least one additional energy layer to produce an expanded candidate layer set, wherein the at least one additional energy layer involves an energy level that has not previously been used
adding (S14; S24) the at least one additional energy to the initial set, to produce an expanded candidate energy layer set
optimizing (S16; S26) a radiotherapy treatment plan based on the expanded candidate layer set.
