Abstract

A system and method is provided for radiation system collimation and design. A plurality of channel waveguide assemblies are provided to be operatively associated with respective beam collimators having varying longitudinal bore diameters. The plurality of channel waveguide assemblies includes a plurality of guides and concentric spacers. The plurality of guides and concentric spacers include varying inner diameters that are configured to be securably nested together by decreasing inner diameters and secured within the longitudinal bores of the respective beam collimators.

First claim

The invention claimed is:

1. A radiosurgery system, comprising:
a patient table configured to receive a patient thereon;
a radiation source comprising an exit orifice configured to emit a beam of radiation along a path extending from the exit orifice toward the patient table to perform radiosurgery on the patient;
a beam collimator arranged with the path and forming a longitudinal bore extending along the path from an inlet and an outlet; and
a channel waveguide assembly sec…
