Introduction: This study investigates basic dosimetric properties of unflattened 6 MV photon beam shaped by multileaf collimator and compares them with those of flattened beams.Materials and Methods: Monte Carlo simulation model using BEAM code was develo... see more
O P Gurjar,R Arya,H Goyal,P Handa,P Bagdare,A Khan,R K Paliwal,S P Mishra
Background: Craniospinal irradiation (CSI) of medulloblastoma poses technological challenges due to the involvement of large treatment volume. Commonly, the whole treatment length is covered with two different isocentric plans in which the junction is shi... see more
A Sinha,N Singh,B M Dixit,N K Painuly,H K Patni,A Yadav
Background: For preclinical evaluations of radiopharmaceuticals, most studies are carried out on mice. Values of electron specific absorbed fractions (SAF) have had vital role in the assessment of absorbed dose. In past studies, electron specific absorbed... see more

Background: Numerous unique characteristics of the nanosized gold, including high atomic number, low toxicity, and high biocompatibility make it one of the most appropriate nanostructures to boost radiotherapy efficacy. Many in-vivo and in-vitro investiga... see more
L Zareei,B Divband,A Mesbahi,M Khatamian,A Kiani,N Gharehaghaji
Background: Magnetic resonance imaging (MRI) contrast agents have an important role to differentiate healthy and diseased tissues. Access and design new contrast agents for the optimal use of MRI are necessary. This study aims to evaluate iron oxide–4A na... see more
S Nadi,A Shabestani Monfared,E Zabihi,A Mahmoudzadeh,N Eyvazzadeh,R Tahamtan
Introduction: The current study investigated the combination of high Z atoms (iodine-, platinium-based drugs) with using low energy irradiation (120kvp) in Anaplastic Thyroid cancer cells.Materials and Methods: For this purpose, eight groups were designed... see more
S M J Mortazavi,A Dehghani Nazhvani,M Paknahad
Background: Previous studies have shown that exposure to electromagnetic fields produced by magnetic resonance imaging or mobile phones can lead to increased microleakage of dental amalgam.Objective: The aim of the present study was to investigate the eff... see more
Z Rojhani-Shirazi,Z Amiri,S Ebrahimi
Background: The maintenance of postural control is a key component in dynamic physical activity, especially during muscle fatigue and against external forces. Despite many studies in this field, there is no consensus regarding the effects of plantar flexo... see more
M Karimpour,H Parsaei,Z Rojhani-Shirazi,R Sharifian,F Yazdani
Background: Electromyography (EMG) signal processing and Muscle Onset Latency (MOL) are widely used in rehabilitation sciences and nerve conduction studies. The majority of existing software packages provided for estimating MOL via analyzing EMG signal ar... see more
