[ 1 ] - میزان رعایت منشور حقوق بیماران در بخش های رادیولوژی بیمارستان های آموزشی شهر همدان از دیدگاه بیماران و پرسنل در سال 1394
Introduction: Hospitals and health centers have a duty to improve service delivery and increase patient satisfaction. Due to the necessity of observing these principles, the present study was conducted to evaluate the observance of patient’s rights in radiology wards of teaching hospitals of Hamadan in 2015. Methods: This descriptive/analytical cross-sectional study was conducted on 13...
[ 2 ] - بررسی مقایسه‌ای دو سیستم Cone Beam CT به لحاظ دقت اندازه‌گیری خطی محل‌های قراردهی ایمپلنت در مندیبل به‌صورت In Vitro
Background and Objective: There are critical areas in the mandible that should be considered during implant placement such as inferior alveolar canal, mental foramen, and the root of the adjacent tooth. Two-dimensional images obtained from periapical, panoramic, and conventional tomography are considered in the evaluation of implant placement and bone quality. Cone-beam computed tomography (CBC...
[ 3 ] - مقایسه دوز جذب سطحی بیماران در آزمون‌‌های CBCT، سی تی اسکن اسپیرال و سی تی اسکن معمول
Background and Aims: The evaluation of absorbed dose received by patients could give useful information for radiation risk estimation. This study was performed to compare the entrance skin dose received by patients in cone beam computed tomography (CBCT), conventional and spiral computed tomography (CT).Materials and Methods: In this experimental study, 81 calibrated TLD chips were used. the TL...
[ 4 ] - بررسی میزان رعایت اصول حفاظت در برابر اشعه در دانشکده‌های دندانپزشکی سراسر کشور
Background and Aim: In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study was designed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran.Materials and Methods: In this cross-sectional study a questionnaire based on National Radiation Protection guidelines wa...
[ 5 ] - Evaluation of dosimetric characteristics of a grid block fabricated for Mega-voltage grid therapy purposes
Background: In conventional radiation therapy, regarding normal tissue tolerance, the treatment of bulk tumors is one of the remaining challenges. Grid Radiation Therapy (GRT) is a technique to deliver high doses, approximately 15 – 20 Gy per fraction, to several small volumes located in a large radiation field. This can be performed using a grid block. The current work has concentrate...
[ 6 ] - Radiation protection principles observance in Iranian dental schools
Background: In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study aimed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran. Material and Methods: In this cross-sectional study a self-administered questionnaire, based on National Radiation Protection ...
[ 7 ] - Iranian physicians\' knowledge about radiation dose, received by patients in diagnostic radiology
Background: Although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. It is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. The purpose of this study has been to investigate the level of physicians' knowledge about radiation d...
[ 8 ] - Use of gold nanoparticles in MAGIC-f gels to 18 MeV photon enhancement
Objective(s): Normoxic MAGIC-f polymer gels are established dosimeters used for three dimensional dose quantifications in radiotherapy. Nanoparticles with high atomic number such as gold are novel radiosensitizers used to enhance doses delivered to tumors. The aim of this study was to investigate the effect of gold nanoparticles (GNPs) in enhancing percentage depth doses (PDDs) within the MAGIC...
