<p>A radiation modulating device and methods enhance the delivery of radiation by modulating the intensity of a radiation beam. A radiation modulating device may be placed between any radiation source and any target such that at least some portion of the radiation beam emitted from the source passes through the radiation modulating device before reaching a target. In one embodiment of the present invention, a radiation modulating device may include a housing and a core. A housing may be configured to support a core and a core may be configured to partially or wholly block one or more portions of radiation emitted from a radiation source. The configuration of the core may be based on a distribution of intensities of radiation desired to be delivered to a target. Though a radiation modulating device according to various aspects of the present invention may be used for any of a number of purposes, one use for the device is to enhance the delivery of radiation therapy to cancer patients.</p> |
