Basic Physics of Digital Radiography

Digital Radiography heralds a new era for medical X-ray imaging. Radiographs can be recorded using digital image receptors and enhanced using computer processing. They can also be transferred to databases for archival and transmission throughout hospitals and clinics. The change from traditional film-based image receptors is similar in many respects to those occurring in digital photography and digital television. Greater precision can now be applied to each stage of the imaging process so that the balance between image quality and radiation dose can at last be controlled accurately. Knowledge and understanding of the basic physics which underlies practice is critical for its successful application in the clinical environment. This wikibook addresses this requirement.
