Abstract
Radiation may be delivered in a number of segments shaped by a multi-leaf collimator. The collimator may be at different angles of rotation for the different segments. A method for planning radiation treatment involves obtaining an optimized set of collimator configurations by a direct aperture optimization method that takes into account collimator rotation. In some embodiments, area constraints are applied to the optimization. Methods according to embodiments of the invention can generate efficient treatment plans.
