[ 1 ] - اندازه‌گیری دوز ورودی سطح و دوز مؤثر بیماران در رادیولوژی قفسه سینه و شکم در همدان و مقایسه با استاندارد جهانی
Background and purpose: By increasing use of X-ray in medical diagnosis, it is essential to gain awareness on the amount of absorbed dose in patients according to the world standard levels. The aim of this study was to estimate the entrance surface dose (ESD) and effective dose (ED) of the patients in imaging (chest and abdomen) with diagnostic radiology systems in Hamadan, Iran; and comparing ...
[ 2 ] - بررسی اثر میدان مغناطیسی بر کورتیزول، قند خون، هورمون‌های تری یدوتیرونین و تیروکسین موش صحرایی
Background and Objective: The widespread use of electromagnetic waves in human life has required the scientific research in the effects of these waves on the health of living beings. Due to the widespread use of these waves and the contradictory results in various researches, more comprehensive investigations are needed in this field. Therefore, the aim of this study was to evaluate the effect ...
[ 3 ] - Comparison of forward intensity modulated radiation therapy and two field tangential wedged beam techniques in radiotherapy of breast cancer: dosimetric and radiobiologic study
Introduction: This study aims to compare the dose delivery parameters and radiobiologic model prediction of Tumor Control Probability (TCP) of the FIMRT technique compared with rectangular two tangential wedged fields (2FW) in the treatment of breast cancer. Furthermore, reduction of the heart and lung dose in the FIMRT was studied via dosimetric parameters and radiobiologic mo...
[ 4 ] - Comparison between field-in-field technique and the use of conventional wedges for treatment planning of esophageal cancer
Introduction: This study was conducted to evaluate and quantify the treatment planning performance of MLC-optimized field-in-field planning technique (FIF), also named forward IMRT, versus wedge-based three field (W3F) technique in terms of dosimetric and radiobiological parameters for esophageal carcinoma. Material and Methods: Twenty patients with esophag...
