    Population of whole-body statistical adult phantoms and assessing the uncertainty of organ doses in hyperthyroid treatment with 131I 

    نوع: Conference Paper
    نویسنده : علّییه حسینیان ازغدی; سیدهاشم میری حکیم آباد; لاله رفعت متولی; Elieh Hoseinian Azghadi; Seyyed Hashem Miri Hakimabad; Laleh Rafat Motavali
    سال: 2015
    خلاصه:

    In this paper, a series of computational phantoms (males and females) were developed based on computed tomography (CT) images of a healthy Iranian population. The Monte Carlo calculation method was then used to estimate ...

    A study of the effect of the lung shape on the lung absorbed dose in six standard photon and neutron exposure geometries 

    نوع: Journal Paper
    نویسنده : عطیه ابراهیمی خانکوک; سیدهاشم میری حکیم آباد; لاله رفعت متولی; Atiyeh Ebrahimi Khankook; Seyyed Hashem Miri Hakimabad; Laleh Rafat Motavali
    سال: 2015
    خلاصه:

    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 ...

    Studying the effect of the lung size variation on dosimetry and systematic parameters of FUM-IVNAA facility 

    نوع: Journal Paper
    نویسنده : عطیه ابراهیمی خانکوک; سیدهاشم میری حکیم آباد; لاله رفعت متولی; Atiyeh Ebrahimi Khankook; Seyyed Hashem Miri Hakimabad; Laleh Rafat Motavali
    سال: 2015
    خلاصه:

    The aim of this paper was quantifying the uncertainties of dosimetry parameters and systematic factors of an in vivo neutron activation analysis (IVNAA) facility for neutron-irradiated individuals with different lung sizes. A series of statistical...

    Evaluating the effects of statistical changes on internal dosimetry 

    نوع: Journal Paper
    نویسنده : Z. Sajjadi; لاله رفعت متولی; سیدهاشم میری حکیم آباد; S. Mohammadi; Laleh Rafat Motavali; Seyyed Hashem Miri Hakimabad
    سال: 2015
    خلاصه:

    Currently, internal dosimetry evaluations are performed using reference computational phantoms. here are significant discrepancies in the organ absorbed doses regarding the variations in organ mass. In this study, to ...

    Determination of the uncertainty in lung dose in an external photon exposure 

    نوع: Conference Paper
    نویسنده : عطیه ابراهیمی خانکوک; لاله رفعت متولی; سیدهاشم میری حکیم آباد; Atiyeh Ebrahimi Khankook; Laleh Rafat Motavali; Seyyed Hashem Miri Hakimabad
    سال: 2013
    خلاصه:

    In the past of 100 years, diagnostic imaging and radiation therapy have gradually become crucial instruments for all branches of medicine. Using radiological techniques increase concern about secondary cancers. To estimate ...

    A feasibility study on the use of phantoms with statistical lung masses for determining the uncertainty in the dose absorbed by the lung from broad beams of incident photons and neutrons 

    نوع: Journal Paper
    نویسنده : عطیه ابراهیمی خانکوک; سیدهاشم میری حکیم آباد; لاله رفعت متولی; Atiyeh Ebrahimi Khankook; Seyyed Hashem Miri Hakimabad; Laleh Rafat Motavali
    سال: 2017
    خلاصه:

    Computational models of the human body have gradually become crucial in the evaluation of doses absorbed by organs. However, individuals may differ considerably in terms of organ size and shape. In this study, the authors ...
