Abstract
A radiation treatment delivery system, includes a linear accelerator (LINAC) and a multileaf collimator (MLC), coupled with the distal end of the LINAC, wherein the MLC has two banks of leaves, organized into a plurality of opposing leaf pairs. The system further includes a processing device, operatively coupled to the LINAC and the MLC, to control the plurality of leaf pairs of the MLC such that for each of a plurality of radiation beam delivery positional sections corresponds to a range of radiation beam positions over a discrete time interval, wherein each leaf pair of the plurality of opposing leaf pairs is open to a fixed opening for a fraction of time in the discrete time interval and closed for the remaining fraction of time in the discrete time interval, while a radiation beam of the radiation treatment system is active.
