Introduction

  • Conventional X-ray film has an intrinsically high resolution exceeding that of many digital systems.
  • Despite this digital radiography has superseded conventional radiography in many hospital departments.
  • Disadvantages associated with conventional film-based radiography may include difficulty or impossibility to correctly expose all areas on a radiograph. A darkroom and chemicals are required to process the radiographs and exposure problems and film faults are common Radiography: film faults. Film is also bulky to store and radiographs are easily lost and difficult to distribute.
  • Digital imaging systems were developed in the early 1980s to overcome some of the problems associated with conventional film-based systems.
