Abstract

This article investigates the impact of shielding devices—thyroid collars, radiation safety glasses, and lead aprons—on radiation doses absorbed by radiosensitive organs (eyes, thyroid, breasts) during cone-beam computed tomography (CBCT) scans using two different fields of view (FOV). Using a tissue-equivalent female phantom and thermoluminescent dosimeters, the study found that shielding significantly reduced absorbed doses by 26.81% to 52.95% across all organs and scanning parameters, while larger FOVs notably increased radiation exposure, especially to the eyes. The findings highlight the importance of optimizing CBCT imaging protocols to balance radiation protection and diagnostic image quality, recommending careful use of shielding devices where appropriate to protect radiosensitive tissues without compromising clinical outcomes.
