Abstract
A method includes detecting a potential setup error in a radiation treatment delivery session of a radiation treatment delivery system, wherein the setup error corresponds to a change in a current position of a treatment target relative to a prior position of the treatment target, and wherein the change includes a rotation relative to the prior position of the treatment target. The method further includes modifying, by a processing device, one or more planned leaf positions of a multileaf collimator (MLC) of a linear accelerator (LINAC) of the radiation treatment delivery system to compensate for the potential setup error corresponding to the rotation of the prior position of the treatment target.
