Research study shows significant radiation dose reductions


New research on cone beam 3D imaging has found that there is a solution for dental professionals who are seeking a low-exposure alternative CBCT scanner. Dr. John Ludlow, a distinguished researcher in imaging technology and radiation dose, has recently published his newest study comparing doses from the newest i-CAT® model of CBCT technology, the i-CAT® FLX, with those from conventional 2D and medical CT imaging alternatives. The study, published in December in the American Journal of Orthodontics and Dentofacial Orthopedics, assessed effective doses of radiation for adults and children resulting from various combinations of field of view size and field location in Imaging Sciences’ i-CAT FLX.1 The study showed, “the QuickScan+ protocol provided a substantial 87% reduction in dose compared with the standard exposure protocols in both child and adult phantoms. Thus, when QuickScan+ protocols can be used, they will provide a clinically meaningful reduction in dose.” While reductions in dose are accompanied by reductions in image quality, these low-dose volumes are useful for specific tasks. Dr. Ludlow noted that the study indicated, “The Quick Scan+ image volume provides 3D information with minimal geometric distortion that is unavailable in any 2D image and at a comparable dose.”
