Hybrid phantom approach for radiation dosimetry applications
Introduction: In the present work, the steps of constructing hybrid phantoms have been studied. Mathematical and voxel phantoms are two various kinds of computational human body models which used in dose evaluations and ...
شبیه سازی مدل کامل سر و گردن انسان بزرگسال و محاسبه دز دریافتی در اسکن تیروئید
According to the daily lives of the rays (used in industry,medicine, power generation,etc.) access to the best ways dosimetry becomes very important. Ionizing radiation have adverse biological effects on the cells.To estimate the effects of dose...
BENCHMARKING OF THE MCNP CODE FOR DOSE ESTIMATION ACCURACY FROM INTERNAL PHOTON SOURCES IN ORNL ANALYTICAL PHANTOMS AT VARIOUS AGES
In external or internal irradiation either diagnostic or therapeutic nuclear medicine, estimation
of absorbed dose in each organ is very important. Most accurate way for this estimation is the
use of Monte ...
Monte Carlo dosimetry for ESSD-TBI
The objective of this work is to apply a Monte Carlo (MC) accelerator model, validated by experimental data at isocentre distances, to a large-field total body irradiation (TBI) technique and to develop a strategy for ...
Assessment of Dose Distribution from I-131 and I-123 Sodium Iodide Administration for Voxel Phantoms
The organ doses from administration of Iodine-131, Iodine-123 sodium Iodide was calculated for the reference voxel phantoms by using the Monte Carlo transport method. Besides, the dose distribution in the body was obtained ...
Investigation and calculation of electron and photon absorbed dose to organs from Radon-222 and its progeny
doses; whereas conversion electrons should be considered in dosimetry calculations as well as beta and gamma-rays.
Conclusion
Some of electron and photon particles emitted by Radon progeny have enough energy to leave...
INTERNAL DOSE TO ACTIVE MARROW AND ENDOSTEUM FROM RADIOACTIVE IODINE
This study analyses the active marrow and endosteum dose differences between the new ICRP male and female reference computational phantoms and the stylized phantom for two thyroid agents. The active marrow and endosteum ...
A Monte Carlo study for photoneutron dose estimations around the high-energy linacs
the Monte Carlo code. The ICRP adult reference male voxel phantom was used as the human body model for Dosimetry calculations.
Results: The results of dose calculations in the isocenter and maze showed that photoneutron dose decreases as the function...
A study of the effect of the lung shape on the lung absorbed dose in six standard photon and neutron exposure geometries
According to the published results of radiation dosimetry studies, there are significant discrepancies in the organ absorbed doses of existing adult male phantoms. As stated, differences in the organ absorbed doses may be associated...
Studying the effects of the lung mass on the absorbed dose to the lung due to the administration of 131I for therapeutic purposes
131I is a radiopharmaceutical used for the treatment of advanced lung cancer, resulting in high organ doses. The effects of the lung mass on the absorbed dose to the lung due to the administration of 131I were studied in ...
