Comparing fetal phantoms with surrogate organs in female phantoms during CT exposure of pregnant patients.

With the rising use of Computed Tomography (CT) in diagnostic radiology, there are concerns regarding radiation exposure to sensitive groups, including pregnant patients. Accurately determining the radiation dose to the fetus during CT scans is essential to balance diagnostic efficacy with patient safety. This study assessed the accuracy of using the female uterus as a surrogate for fetal radiation dose during CT imaging.

Relative response of dosimeters to variations in scattered X-ray energy spectra encountered in interventional radiology.

Purpose: The new lower eye lens dose limit is of relevance in interventional radiology, where higher dose procedures result in increased scattered radiation to staff. The eye lens dose may be monitored using the directional dose equivalent at 3 mm depth, H(3), or through H(10) or H(0.07) measurements and using conversion factors.
