Abstract
A digital X-ray system for capturing high quality images by maximizing the collection of emitted light from an intensifying screen in response to X-ray impact. The digital X-ray system includes a housing having a fluorescent intensifying screen for receiving emitted X-rays, two reflectors for maximizing light collection and optimizing the light path from the intensifying screen, and a lens assembly. A CCD chip receives the light from the lens assembly, to provide a digital image for immediate on-board processing or post-processing by a computer. The housing is compact, and can be used as a direct replacement for traditional film cartridges without major modifications to the system. The lens assembly includes freeform matched lenses to remove optical distortions, and the housing includes a light sensor for providing exposure measurement and feedback. The system is designed to be quasi-monochromatic to maintain consistent image quality over the entire area of the intensifying screen.
