Calculation of Photons Reaction Rate Resulting at 120 kVp X-ray Tube Voltage and 1 mAs as Function to Digital Imaging and Communications in Medicine Pixel Numbers Using Monte Carlo N-Particle Transport and a Voxel Model of a 29-Year-Old Patient.
Computed tomography, contributes over 34% of collective dose from diagnostic X- rays examination in the world,
where the dose resulting from CT scanner, therefore the difference is very large between the two scans can be reach to 400-500 times.
Because these radiations is not visible, the resulting dangers do
not appear directly, but have a stochastic effects that can appear in subsequent years or generations, It was therefore necessary to adjust and monitor the radiation doses resulting from these practices and to assess the radiation risks resulting from them.
The effective dose resulting from the computed tomography and each of the traditional
imaging of the chest and the number of years of exposure to natural background radiation which produces the same effective
dose resulting from computed tomography.
According to some statistics, the number of computed
tomography devices in Syria exceeds 232 devices, serving more
than 19 million people, where one machine serves about 86 thousand people, therefore It is necessary to assess the effects of these devices on an ongoing basis.
Monte Carlo n–particle code is a general-purpose MCNP that can be
used for neutron, photon, electron, or coupled neutron/photon/electron transport,
including the capability to calculate given values for critical systems.
