[ 1 ] - ارزیابی دز دریافتی بیماران تحت عمل های ارتوپدی با استفاده از فانتوم محاسباتی شبه انسانی و اندازه گیری های تجربی
Introduction: The use of ionizing radiation in diagnosis and treatment of diseases has become inevitable in most medical branches. One of the important sections in medicine is orthopedic surgery room, which also serves to operate many of bone injuries. The aim of this study was to measure the delivered doses to the patients undergoing orthopedic surgeries in common and high usage radiographic i...
[ 2 ] - بررسی آثار رادیوبیولوژیکی و راهکارهای مراقبت‌های پزشکی بعد از انفجار هسته ای
Introduction: Individual exposure after a nuclear detonation (atomic bomb) delivers abundant doses with high dose rates to the people who were located near the nuclear detonation location or within the fallout zone. Effects of the radiation to the humans and animal models will be studied and a fundamental ground work of medical services and managing systems for such accidents wo...
[ 3 ] - معرفی روش جدید ارزیابی گاما وزن داده شده برای مقایسه توزیع دوز به دست آمده از الگوریتمهای محاسباتی دوز با نتایج تجربی در پرتودمانی
Introduction: One of the problems that exists in the quality control procedure of the treatment planning systems and the computer simulation of the radiotherapy or diagnostic radiology validation is comparing the dose distribution resulted from the dose calculation algorithms with the experimental results(as a reference). For this purpose, several methods have been proposed to compare these dos...
[ 4 ] - ارائه روش پرتودرمانی تطبیقی جدید تک ایزوسنتریک در پرتودرمانی خارجی دیواره سینه بیماران مستکتومی شده
Introduction and purpose: The aim of this study is introducing a new Mono-Isocentric Technique)MIT) for external radiotherapy of the chest wall in the mastectomy patients with 6MV photon beams and comparing this technique with the Dual-Isocentric Technique(DIT). Materials and methods: Data of 18 mastectomy patients having chest wall radiotherapy were used. The target tissue was divided into...
[ 5 ] - Assessing the image quality and eye lens dose reduction using bismuth shielding in computed tomography of brain
Background: Epidemiological studies show that computed tomography (CT) is one of the main sources of ionizing radiations. Shielding of radiosensitive organs is one of the dose reduction methods. This study aimed to assess the eye lens dose reduction and image quality resulting from the use of radio-protective bismuth shield in brain CT imaging. Methods: Bismut...
