1. A computer implemented method of developing a radiation treatment plan comprising spot scanning of a treatment target, said method comprising:
accessing information associated with a patient and information pertaining to a radiation delivery machine;
determining an area associated with the treatment target, wherein the area comprises a plurality of spots;
computing a weighting for each spot of the plurality of spots, wherein the weighting is associated with a number of protons delivered at a respective spot;
computing timing related parameters based on information retrieved from the radiation delivery machine; and
determining a transition dose delivered by the radiation delivery machine during a transition from one spot to another spot when irradiating the treatment target under the radiation treatment plan.
