Eye lens doses in the head pediatric CT examinations

Abstract

In this work we investigated the dose in the eyes of 25 pediatric patients, from 0 to 3 years, submitted to CT head exam, using TLD dosimeters inside a tube set perpendicularly to the orbito-meatal baseline. The results shown that the absorbed eyes dose varied from 63.0 to 94.6 mGy with an average uncertainty of 28 %. These results confirm the findings of similar studies considering the differences of protocols and scanner design.
