摘要：

A sharpening filter for orthovoltage x-ray beams employs a substantially planar filter disk supporting a set of radial symmetric features controlling attenuation of x-ray transmission in concentric circular regions providing increased sharpness of the pencil beams in a compact filter structure that may be tailored to different beam sizes and focus depths.
