Workload can be reduced by using class solutions for each tumour site
A class solution should consist of…
the required structures to be used in optimisation and the allowed ranges of
the associated optimisation objectives, constraints and weights
a standard set of technical requirements :
the number of fields
desired start and stop angles
collimator settings
beam energies
control point spacing
dose grid size
By controlling the range of parameters using class solutions it promotes
similarity of plan characteristics
