Optimization of Radiation Dose for Brain Computerized Tomography

Abstract:

This study was conducted to evaluate the effective dose in adults during the examination of the brain computed tomography. The motivations for this study that frequency of the brain CT test is high and the radiation field of brain CT contain sensitive organ like eyes. By mathematical equation after it has been collecting the factors that affect the amount of radiation from producer ray tube in addition to the two factors CT radiation dose index (CTDI) and the dose length product (DLP) .the cancer risk was calculated by special program by used the factor dose length product. This study was done in three different centers on three different devices in the generations to collect 60 samples from (1-7-2014) to (10/03/2015) The study found that the effective dose in the first center (A1) may be worth (3.29 ± 0.55 ) This value is higher than the agreed value of the world while in second center (B2) has reached the value (0.545 ± 0.21) and this was set up by Ali that they value are also acceptable in third center (C3) amounted to value (2.0123 ± 0.24) which is also acceptable.
