[ 1 ] - Investigating the Rate of Adaptation between the Courses of Radiation Technology and Job Requirements from the Perspective of Graduates
Introduction: the experts of radiology play a crucial role in the treatment programs of the patients in hospitals. Therefore, in order to recognize the needs, the experts’ opinion should be obtained about whether the educational program meets the job requirements or not. The purpose of the present study is to investigate the rate of adaptation between the courses of radiation technology and job...
[ 2 ] - Local Diagnostic Reference Levels for Some Common Diagnostic X-Ray Examinations In Sabzevar County of Iran
Introduction: Diagnostic reference level (DRL) is a useful tool for the promotion of optimization. The national DRLs (NDRLs) are useful, brief, and robust guidelines for optimizing radiation protection in a country. The aim of this study was to extract the local DRLs (LDRLs) for some common radiologic examination in Sabzevar county. Materials and Methods: There are eight radiology departments ...
[ 3 ] - Assessment of the Preventive Effect of Pilocarpine on Radiotherapy-Induced Xerostomia in Patients with Head and Neck Cancers
Introduction Xerostomia is one of side-effects of radiotherapy for head and neck cancers. No definitive method has been proposed for the treatment of this condition. However, pilocarpine is considered effective for the management of chronic xerostomia. The purpose of the present study was to assess the preventive effect of pilocarpine. Materials and Methods This study was performed on 34 patien...
[ 4 ] - Excess Cancer Risk Assessment from Some Common X-Ray Examinations in Sabzevar County
Introduction: Nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. Using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. X-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. These effects obey the LNT hypothesis that occur at lo...
[ 5 ] - محاسبه دوز رسیده به گنادها ناشی از برخی رادیوگرافی تشخیصی رایج
Background and Aim: The basic aim in radiography is to scan a clear image from the body organs, but the issue of the patient's protection against the harmful effects of ionizing radiation should never be neglected.The present study aimed at calculating the received drug to the perigonadic areas during radiography. Materials and Methods: In the current study thermoluminescence dosimeter w...
[ 6 ] - Evaluation of Knowledge, Attitude, and Performance of Radiographers towards Radiation Protection in Southern Khorasan Province, Iran
Introduction: Nowadays, X-ray radiographic imaging plays an essential role in disease diagnosis and treatment. In addition to benefits, X-rays have harmful effects for both patients and radiographers. Observing radiation protection principles reduces radiation exposure and the probability of radiation risk. Therefore, we sought to assess the knowledge, attitude, and performance of radiographers...
[ 7 ] - Sex-related Left Ventricle Rotational and Torsional Mechanics by Block Matching Algorithm
Background: The aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age.Materials and Methods: In this analytical study, twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angel...
[ 8 ] - Natural Gamma Radiation and Effective Annual Dose in Hot Springs in South Khorasan Province, Iran
Background and purpose: Background radiation exists naturally in the environment and human has been always exposed to it. These rays can affect living creatures and cause chromosomal damage, and genetic and somatic diseases. Hot water springs are a major source of background radiation. This study aimed at investigating the absorbed dose of environmental gamma and determining the annual effecti...
