Assessment of Radiation Dose for pediatric in Brain computed tomography

Abstract

This study aims to assess the effective dose radiation received by pediatric brain when the ages from (1 month to 168 month). Study included number of 30 patients. Two type of computed tomography machines (dual slice – 64 slice ) where used in this study . The study was conducted at three radiation centers in Khartoum. After the effective dose was measured throw (Dose length product) the study showed that the average effective dose was (1.464965 mSr). The effective dose compared with the age of each patient. It was found that the effective dose was directly proportional with the age, and that was an inverse relation between the effective dose and slice thickness. When the radiation dose was compared with the used machines it was found that the dose was greater when the 64 slice machine was used.
