Patient Centering in MDCT: Dose Effects
Appropriate patient centering is of pivotal importance in CT scanning. Without good centering there can be increase in patient radiation dose and loss of image quality, effects that are especially pronounced with use of automatic exposure control techniques. This chapter discusses implications of off-centering of patients during CT scanning.
