A faculty member (Associate Professor) of the Department of Medical Physics of Tarbiat Modares University (Tehran, Iran) with general research interest in the application of ionizing radiation in medical diagnosis and treatment (radiology and radiotherapy, radiobiology and radiation protection started from 1978 up until Now. Member of National (Audit and Evaluation) Specialized Board of Medical Physics of the Ministry of Health and Medical Education of Iran from 1998 till now and Secretary of National (Audit and Evaluation) Specialized Board of Medical Physics from 2019 till now. A full member of Iranian Association of Medical Physicists (IAMP), Asian Federation of Medical Physics (AFOMP), International Federation of Medical Physics (IFOMP) and PIP member of American Association of Medical Physicists (AAPM) and a member of the IPEM from 1992 (being suspended because of to not being able to pay its subscription fee due to the economic sanction imposed on Iranian banks for money orders to overseas countries). Having published tens (about: 180) of scientific original papers at various specialized national and international medical physics related journals on different topics aimed for the development of conventional and novel diagnostic and treatment methods based on medical physics knowledge and science.

Gold nanoparticles (GNPs) have been used to sensitize cancer cells and enhance the absorbed dose delivered to such cells. Active targeting can provide specific effect and higher uptake of the GNPs in the tumor cells, while having small effect on healthy cells. The aim of this study was to assess the possible radiosensitiazation effect of GNPs conjugated with AS1411 aptamer (AS1411/GNPs) on cancer cells treated with 4?MeV electron beams. Cytotoxicity studies of the GNPs and AS1411/GNPs were carried out with MTT and MTS assay in different cancer cell lines of MCF-7, MDA-MB-231 and mammospheres of MCF-7 cells. Atomic absorption spectroscopy confirmed the cellular uptake of the gold particles. Radiosensitizing effect of the GNPs and AS1411/GNPs

Background: Intensity-modulated radiotherapy (IMRT) is one of the most usable methods in prostate radiotherapy that is used with different techniques. The aim of this study was to evaluate and compare the dosimetric and radiobiological effects of prostate IMRT techniques regarding to joint volume between the target tissue and organs at risk as a patients anatomical parameter.Methods: This research was a cross-sectional, analytical, and quantitative study that was carried out from April 2016 to June 2018 at the radiotherapy and oncology center of Shoheday-e-Tajrish Hospital and Medical Physics Department of Tarbiat Modarres University Tehran, Iran. Four various prostate IMRT techniques (9, 7 and 5 fields and automatic) were planned on 63 pro
Background: The relationship between the prostate IMRT techniques and patients anatomical parameters has been rarely investigated.Objective: to evaluate various prostate IMRT techniques based on tumor control and normal tissue complication probability (TCP and NTCP) values and also the correlation of such techniques with patients anatomical parameters. Methods: Four IMRT techniques (9, 7 and 5 fields and also automatic) were planned on the CT scans of 63 prostate cancer patients. The sum of distances between the organs at risk (OARs) and target tissue and also their average joint volumes were measured and assumed as anatomical parameters. Selected dosimetric and radiobiological parameters (TCP and NTCP) values were compared among various te
AimTo quantify the relationship between the planning target volume (PTV) dose homogeneity and organs at risk (OARs) sparing in correlation with anatomical parameters in prostate intensity-modulated radiotherapy (IMRT).Materials and methodsNine IMRT plans with various target dose constraints’ priorities were created for 15 prostate cancer patients. Selected PTV and OARs parameters were calculated for the patients. A trade-off was assessed between homogeneity index (HI) and OAR sparing. Several anatomical parameters were evaluated to investigate their effects on the OAR sparing and HI.ResultsInverse exponential relationships were found between the OAR sparing and HI (average R2 of 0?983 and 0?994 for bladder and rectum, respectively).

Purpose To evaluate the effects of retinitis pigmentosa (RP) on time, frequency, and time–frequency components of Xenon flash ERG signals using Fourier and wavelet transforms. Methods Xenon flash ERG was done in 18 eyes of nine RP patients and 20 normal eyes. After examining latency and amplitude, Fourier and wavelet transforms were performed using MATLAB software. Then, we extracted the mode frequency from the Fourier transform and main frequencies and their occurrence time from the wavelet transform. Finally, mean differences were analyzed using statistical tests. Results The results indic
