1. A method comprising:
by a control circuit:
accessing patient information for a particular patient, radiation treatment information, and information regarding a particular radiation treatment platform that includes at least one multi-leaf collimator;
optimizing a radiation treatment plan to dose at least one treatment volume in the particular patient using the particular radiation treatment platform as a function of the patient information, the radiation treatment information, and the information regarding the particular radiation treatment platform, wherein the optimizing:
does not include optimizing movement of any leaves of the multi-leaf collimator; and
comprises optimizing the radiation treatment plan as a function, at least in part, of monitor unit modulation by optimizing monitor unit modulation as a function of a least one of at least one target coverage metric and at least one normal tissue treatment objective, with monitor units serving as an only parameter that is being optimized using a corresponding cost function.
