Learning objectives

During neonatal cardiac CT examination, the eye lens and gonads are known to be organs at high risk.  Because these organs are located outside the irradiation field, they cannot be evaluated by the CT dose index (CTDI).  In this study, the dose measurement was performed using a neonate phantom using small type optically stimulated luminescence dosimeters (OSLD).
