Claim 23:
24. A computer-implemented method comprising:
receiving a projection image that represents a view of an anatomical region of interest;
applying a neural network to the projection image to estimate an aperture image of one or more multi-leaf collimator (MLC) leaf positions for a specified gantry angle corresponding to the view of an anatomical region of interest, the neural network trained for a plurality of gantry angles of a radiotherapy treatment machine based on training data comprising image data for the plurality of gantry angles, wherein the image data comprises a given projection image that represents a view of an anatomy of a subject from a given gantry angle and a corresponding given graphical aperture image of one or more MLC leaf positions at the given gantry angle; and
generating a radiotherapy treatment plan based on the estimated aperture image of the MLC leaf positions.
