The ALARA Principle and 3D Dental Imaging

Posted On: Friday, June 6th 2014 by

How does 3D imaging measure up when compared to 2D digital panoramic and cephalometric radiographs when it comes to radiation doses? Not only a sound safety principle, ALARA (“As Low As Reasonably Achievable”) is a regulatory requirement for all radiation safety programs.

If you’ve ever wondered if the X-ray exposure from Cone Beam 3D scanning makes it more difficult to adhere to the ALARA principle compared to 2D imaging, you’ll be interested in this new study by Dr. John Ludlow, one of the foremost experts on X-ray dosimetry and effective dose related to dental imaging. The study shows that 3D information can be obtained with lower radiation dose than traditional 2D imaging methods. Dr. Ludlow’s analysis notes that i-CAT® FLX QuickScan+ scans expose patients to less effective dose than the combined doses of representative modern 2D digital panoramic and cephalometric radiographs.

To hear more about the study, Dr. Sean Carlson continues the discussion on radiation doses and the i-CAT FLX QuickScan+ in his dental podcast.
