Measurement of Radiation Dose In Brain Computed Tomography

Abstract

Computed tomography (CT), is an X-ray procedure that generates high quality cross-sectional images of the body, and comparison to other radiological diagnosis, CT is responsible for higher doses to patients. The general objective of this study to measure effective radiation dose of brain and confirm is there any difference between effective dose of male brain and female brain according to differences at anatomical structure of male brain and female brain, then correlation between effective radiation dose and mAs. The data of this study were collected from IBN AL Haitham DIAGNOSTIC CENTER ,Anumber of 60 patients(50% male and 50%female) by used Asteion Toshiab (4 slice) by selected same value of KVP(120). The study showed amount of average effective radiation dose (1.8776 msv) and it's not above from standard effective dose of brain (2 mSv) that recommended by ICRP. Also there is no any difference between effective dose of male brain and female brain according to differences at anatomical structure of brain we found the effective radiation dose of male equal (1.9601 msv) and effective radiation dose of female equal (1.7952 msv) .and proportional relation between effective radiation dose and mAS.
