UTILIZING AN OFFSET MULTI-LEAF COLLIMATOR TO IMPROVE DOSE CONFORMALITY AND HOMOGENEITY

Abstract:

A radiation delivery system includes a radiation source to generate a radiation beam to deliver to a target and a multi-leaf collimator (MLC) operatively coupled to the radiation source, wherein the MLC is offset to shift the MLC in a direction relative to a line from the radiation source to a point of interest to cause projections of the radiation beam to be shifted based on the offset.
