Foetal doses were measured, revealing values between 0.4 and 3.9 µGy for sinus imaging.
Cervical spine examinations showed foetal doses ranging from 2.2 to 32.6 µGy, highest in the third trimester.
A conversion factor for estimating foetal dose from kerma area product (KAP) ranges between 0.0002-0.007 µGy/mGy cm2.
Overall, doses from the supine CBCT device are low, indicating minimal radiation risk to the foetus.
