Abstract
An apparatus for modulating an intensity of a radiation beam includes a filter having a cross sectional shape such that a radiation beam filtered therethrough and passed through a patient will have an intensity that is substantially non-uniform. An apparatus for modulating an intensity of a radiation beam generated by a radiation source includes a filter, and a positioner secured to the filter, the positioner configured to move the filter relative to the radiation source.
