 Specially designed CBCT (cone beam CT) scanners can be used instead, which produce adequate imaging with a stated tenfold reduction in radiation.Although computed tomography offers high quality images and accuracy, the radiation dose of the scans is higher than the other conventional radiography views, and its use should be justified.Controversy surrounds the degree of radiation reduction though as the highest quality cone beam scans use radiation doses not dissimilar to modern conventional CT scans.
