This was one of the first studies to provide patient effective dose levels for DE extremity, dento-maxillofacial and ENT CBCT imaging, for adult as well as pediatric patients, based on Monte Carlo simulations. The obtained dose levels can be considered acceptable, particularly since this is, to the author’s best knowledge, the first commercially available model on the European market. Further introduction of this new imaging modality into clinical practice, will possibly enable future clinical application specific dose optimization studies.
