متن کاملThe Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom
Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...
متن کاملEstimation of patient organ doses from CT examinations in Tanzania
Although the use of computed tomography (CT) in medical diagnosis delivers relatively higher radiation doses to patients than other radiological procedures, lack of optimized protocols could be an additional source of increased dose in developing countries. The aim of this study was to determine the magnitude of radiation doses received by selected radiosensitive organs of patients from CT exam...
متن کاملThorax organ dose estimation in computed tomography based on patient CT data using Monte Carlo simulation
Background: This study presents patient specific and organ dose estimation in computed tomography (CT) imaging of thorax directly from patient CT image using Monte Carlo simulation. Patient's CT image is considered as the patient specific phantom and the best representative of patient physical index in order to calculate specific organ dose. Materials and Methods: EGSnrc /BEAMnr...
متن کاملMeasurement of organ dose in chest CT examination using Monte Carlo simulation
Background: Exposure conditions in CT examinations are quite different from conventional Xray. In CT examination higher dose is given to patient in comparison with the dose in other diagnostic examinations. In order to calculate organ effective dose in chest CT, Monte Carlo simulation has been used in this study. Materials and Methods: The Impact survey data were used to determine the ...
