Comparison between measured and calculated equivalent doses in CT using anthropomorphic pediatric phantoms

Due to the significant increase in pediatric trunk computed tomography (CT) examinations, there is a need for a reliable approach of conducting effectivedose estimate for such procedures. The current study is based on two dosimetric anthropomorphic phantoms representing a 1-year and a 5-year old child. Effectiveand equivalent tissue doses from CT examinations of the trunk were determined by thermoluminescent dosimeters (TLDs) and the CT-Expo software. The results of the two investigated methods show good agreement
