DIGITAL IMAGE COLLECTOR FOR X-RAY SYSTEMS.

摘要

A digital X-ray system for capturing high quality images by maximizing the collection ofemitted light from an intensifying screen in response to X-ray impact. The digitalX-ray system includes a housing having a fluorescent intensifying screen forreceiving emitted X-rays, two reflectors for maximizing light collection andoptimizing the light path from the intensifying screen, and a lens assembly. ACCD chip receives the light from the lens assembly, to provide a digital image forimmediate on-board processing or post- processing by a computer. The housing iscompact, and can be used as a direct replacement for traditional film cartridges withoutmajor modifications to the system. The lens assembly includes freeform matchedlenses to remove optical distortions, and the housing includes a light sensorfor providing exposure measurement and feedback. The system is designed to bequasi-monochromatic to maintain consistent image quality over the entire areaof the intensifying screen.
