The productivity-improving features of a direct digital radiography system for projection radiography are introduced and the integration of the system with PACS is discussed. A flat panel digital array, an array controller, and a system controller with video monitor and standard interface to a local...

There are two types of detector systems that can be purchased with digital radiography systems: computed radiography (CR) and direct digital radiography (DR). CR systems use imaging plates to generate a digital image and they are generally less expensive than DR. While both CR and DR generate ...

, such as E94-04 and E2698-10 (ASTM, 2012), provide useful information on image quality, precision, and potential bias (e.g.,geometric unsharpness, distortions, and backscattering due to variations in object-to-film/source-to-object distances) for both film-based anddigital radiography....

Flat-panel detector (FPD) digital radiography systems have direct and indirect conversion systems, and the 2 conversion systems provide different imaging performances. We measured some imaging performances [input-output characteristic, presampled modulation transfer function (presampled MTF), noise power sp...
