Abstract:
Dose-reducing techniques and patients' radiation protection are of more concern today than in the past with the increased dose used in multi-detector computed tomography (MDCT) compared to single detector scanners. Companies that produce MDCT scanners can, and most often do, apply software that complies with the as low as reasonably achievable (ALARA) principle and decreases the dose used for the imaging. New ways have been discovered to reduce the dose to patients' radiosensitive organs through in-plane bismuth shielding. Different sizes and thicknesses of the shields are available to cover patients more radiosensitive organs. This literature review describes the uses, benefits, and some concerns of in-plane bismuth shielding.
