1. A radiation delivery system, comprising:
a radiation source to generate a radiation beam to deliver to a target, wherein a line extends from the radiation source to a point of interest including the target; and
a multi-leaf collimator (MLC) operatively coupled to the radiation source, wherein the radiation source and the MLC move along a path of rotation about the point of interest, and wherein the MLC is offset to shift the MLC by a positive or negative one-quarter leaf width in a direction parallel to the path of rotation and perpendicular to the line to cause projections of the radiation beam to be shifted based on the offset.
