Application of Shielding in CT Radiation Dose Reduction

Part of the Medical Radiology book series (MEDRAD)


In-plane shields have been shown to reduce CT radiation dose to some of the most radiosensitive organs. However, potential for artifacts and changes in attenuation numbers make their universal use controversial for radiation protection purposes. In this chapter, we discuss advantages and disadvantages of use of in-plane shielding for reducing radiation dose associated with CT scanning.
