About Digital Radiography

Digital radiography is a type of x-ray imaging where digital x-ray sensors are used instead of traditional photographic film. There are many advantages to digital radiography, such as:

  • Time efficiency by bypassing chemical processing
  • Ability to digitally transfer and enhance images
  • Less radiation is produced
  • Immediate image preview and availability
  • Elimination of costly film processing steps
  • A wider dynamic range

An estimated 1% of cancer cases may be associated with medical/dental radiation. Medical radiation is about 8 times more than dental. One-time dose in uSv can cause:


100,000 - Thyroid Cancer
250,000 - Skin Cancer
3D dental x-ray doses are about 0.002% of this amount. The following table describes radiation sources and the effective dose exposure:
