The lens of the eye and breast are considered among the most radiosensitive tissues of the human body. Increased attention should thus be given to minimize radiation dose to these tissues, especially in children that are considered more radiosensitive than adults and are more likely to undergo multiple CT examinations during their lifetime.
Organ-based tube current modulation (OTCM) techniques reduce the x-ray tube current (mA) over the anterior part of the patient’s body circumference aiming to minimize radiation exposure to superficial radiosensitive organs such as eyes, thyroid and breasts. To our knowledge there is no published data on the effect of OTCM on radiation dose to superficial radiosensitive organs and image quality in pediatric CT.
The purpose of this study was to investigate the effect of an organ-based tube current modulation (OTCM) technique on organ absorbed dose and assess image quality in pediatric CT examinations.
