context_page_description: Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers in fluoroscopy equipment.
context_section_description: Flat-panel detectors are more sensitive and faster than film. Their sensitivity allows a lower dose of radiation for a given picture quality than film. For fluoroscopy, they are lighter, far more durable, smaller in volume, more accurate, and have much less image distortion than x-ray image intensifiers and can also be produced with larger areas. Disadvantages compared to IIs can include defective image elements, higher costs and lower spatial resolution.
  In general radiography, there are time and cost savings to be made over computed radiography and (especially) film systems. In the United States, digital radiography is on course to surpass use of computed radiography and film.
  In mammography, direct conversion FPDs have been shown to outperform film and indirect technologies in terms of resolution, signal-to-noise ratio, and quantum efficiency. Digital mammography is commonly recommended as the minimum standard for breast screening programmes.
