Abstract
A method for delivering radiation from a radiation source to treatment a area utilizing a multi-leaf collimator. The method includes positioning the multi-leaf collimator between the radiation source and the object to block a portion of the radiation. The leaves of the multi-leaf collimator are generally located within a plane and extend longitudinally along a first axis. The leaves are positioned to define a first treatment field. The method further includes delivering radiation to the first treatment field and rotating the multi-leaf collimator about a central axis extending generally perpendicular to the leaf plane. The leaves are positioned to define a second treatment field and radiation is delivered to the second treatment field
