1. A method of determining an estimated dose delivered by a proton therapy plan, said method comprising:
defining a representation of a volume of interest based on user input received from a graphical user interface;
subdividing the representation of the volume of interest into a plurality of voxels;
assigning metrics including volume of interest metrics and proton beam metrics to the plurality of voxels; and
determining the estimated dose delivered by the proton therapy plan according to the metrics.
