Claim 8:
9. A method for determining a radiotherapy treatment plan comprising:
receiving anatomical data for a patient;
receiving beam orientation data, wherein the beam orientation data comprises information on pre-selected beam orientations;
generating, via a neural network analyzing the anatomical data and the beam orientation data, a first plurality of fitness values for a plurality of candidate beam orientations, each fitness value corresponding to a candidate beam orientation of the plurality of candidate beam orientations;
determining a first selected beam orientation based on the first plurality of fitness values;
generating updated beam orientation data that comprises information associated with the first selected beam orientation;
generating, via the neural network analyzing the anatomical data and the updated beam orientation data, a second plurality of fitness values for the plurality of candidate beam orientations, each fitness value corresponding to a candidate beam orientation of the plurality of candidate beam orientations;
determining a second selected beam orientation based on the second plurality of fitness values;
performing a fluence map optimization (FMO) process on the first and second selected beam orientations; and
determining a dose distribution for the patient based on the FMO process.
