Abstract
A collimator having slits of varied widths, wherein each slit includes a curved side profile having a common axis of curvature for providing a cross-section of an emitted beam of energy with a substantially uniform width when the common axis of curvature of the slit intersects a focal spot of a source of the beam. The collimator is curved about a rotation axis substantially normal to the common axis of curvature, such that rotating the collimator about the rotation axis will sequentially position the slits to collimate the emitted beam.
