Reduction of effective dose and organ dose to the yey lens in head MDCT using iterative image reconstruction and automatic tube current modulation

Abstract

To compare the effective and eye lens radioation dose in helical MDCT brain examinations using automatic tube current modultation in conjunction with either standard filtered bac projectioin (FBP) technique or iterative reconstructioin in image space (IRIS).
