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.
