Abstract
A radio therapy system includes a first x-ray source. The first x-ray source is configured to produce first x-ray photons in a first energy range suitable for imaging and project the first x-ray photons onto an area designated for imaging. The system includes a second x-ray source configured to produce second x-ray photons in a second energy range higher energy than the first energy range, produce third x-ray photons in a third energy range higher energy than the first energy range, project the second x-ray photons onto the area designated for imaging, and project the third x-ray photons onto an area designated for treatment. The system includes an analytical portion configured to collect and combine data to create a composite output including at least one image, the combining based in part on a spectral analysis.
