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.
