[ 1 ] - Monte Carlo Study of Several Concrete Shielding Materials Containing Galena and Borated Minerals
Introduction: The heavyweight concretes have been widely used for constructing medical or industrial radiation facilities with photon sources. Materials and Methods: In this study, heavy concretes containing galena (PbS) and several borated minerals are proposed as suitable materials against photons. The shielding properties of 21 galena concretes containing seven borated minerals with three m...
[ 2 ] - Discrepancies in dose distributions due to age- dependent bone electron density in pediatric MRI-only treatment planning: A Monte Carlo study
Introduction: MRI-only treatment planning (TP) can be advantageous in paediatric radiotherapy. However, electron density extraction is necessary for dose calculation. Normally, after bone segmentation, a bulk density is assigned. However, the variation of bone bulk density in patients makes the creation of pseudo CTs challenging. This study aims to assess the effects of bone den...
[ 3 ] - Comprehensive TLD dosimetry of physicians and patients during interventional angiography procedures to estimate the risk of radiation deterministic effect
Introduction: Interventional angiography procedures are increasingly used today. These techniques require a long time of standing near the patient and x-ray tube which lead to increase the radiation-dose of the staff and interventionists. This may also, in turn, lead to the occurrence of radiation deterministic effects. Since a large number of interventional radiology were perf...
[ 4 ] - Investigation of the Entrance Surface Dose and Dose to Different Organs in Lumbar Spine Imaging
Background: Dose assessment using proper dosimeters is especially important in radiation protection optimization and imaging justification in diagnostic radiology.Objective: The aim of this study is to obtain the Entrance Skin Dose (ESD) of patients undergoing lumbar spine imaging using two thermoluminescence dosimeters TLD-100 (LiF: Mg, Ti) and GR-200 (LiF: Mg, Cu, P) and also to obtain the ab...
[ 5 ] - بررسی آناتومی اسکلت اندام حرکتی قدامی و خلفی لاکپشت برکه‌ای خزر، Mauremys caspica (Gmelin, 1774) (Reptilia: Geomydidae) توسط توموگرافی کامپیوتری (سی تی اسکن): اطلس اندام حرکتی قدامی و خلفی لاک-پشت برکه‌ای خزری
آگاهی از آناتومی طبیعی بدن گونه‌های مختلف جانوران برای تشخیص موارد غیر طبیعی و بیماری‌ها الزامی است. به صورت سنتی اطلاعات آناتومی بر علوم و فنون تشریح تکیه دارد، اما امروزه این روش‌های سنتی تا حد زیادی توسط روش‌های جدیدی که در حیوانات زنده سریع، دقیق و غیر‌تهاجمی هستند مانند توموگرافی کامپیوتری (سی تی اسکن) و تصویربرداری تشدید مغناطیسی (ام آر آی) جایگزین شده‌اند. در مطالعه‌ی حاضر ساختارهای طبیع...
[ 6 ] - Assessment of Different Training Methods in an Artificial Neural Network to Calculate 2D Dose Distribution in Radiotherapy
Introduction: Treatment planning is the most important part of treatment. One of the important entries into treatment planning systems is the beam dose distribution data which maybe typically measured or calculated in a long time. This study aimed at shortening the time of dose calculations using artificial neural network (ANN) and finding the best method of training t...
[ 7 ] - Assessment the Adherence of Radiologists to the Thyroid Imaging Reporting and Data System (TIRADS)
Introduction: Thyroid nodules are the most common findings among adults. Usually, Fine Needle Aspiration Biopsy (FNAB) can be used to distinguish the malignant and benign lesions. Application of a non-invasive method for determining the chance of malignancy in a nodule is desirable. Thyroid Imaging Reporting and Data System (TIRADS) was introduced to decrease the unnecessary FNABs and to optimi...
[ 8 ] - Assessment of the frequency of MRI findings in neonates under 6 months who referred to Shiraz hospitals with seizures
Background: Neonatal seizures can have many causes. Determining the underlying cause of neonatal seizures is very important in determining the prognosis, outcome, and treatment strategies. In this study, we have evaluated the frequency of Magnetic resonance imaging (MRI) findings in neonates younger than 6 months who had been referred to Shiraz Namazi hospital with seizures to determine the pre...
