[ 1 ] - Introducing an Optimized Method for Obtaining X-ray Diffraction Patterns of Biological Tissues

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...

[ 2 ] - بررسی سطح آگاهی، نگرش و عملکرد پرتوکاران رادیولوژی استان یزد در مورد حفاظت پرتویی

Background: Radiology tests are used to diagnose a variety of diseases. Performing such examinations has potential risks for patients and radiographers working in radiology departments. These risks can be minimized by compliance with safety practices. The aim of this study was to assess the knowledge, attitude, and practice of radiographers working in the radiology departments of Yazd about the...

[ 3 ] - بررسی میزان آگاهی بیماران مراجعه‌کننده به مراکز تصویربرداری بیمارستان‌های استان یزد در مورد خطرات پرتوهای یونیزان در سال 1393

Introduction: Patients should be aware of the risks of ionizing radiation used in medical imaging procedures to make appropriate decisions about the diagnosis and treatment of their disease. The aim of this study was to assess the awareness of radiation risks associated to radiological and CT scans tests among the referring patients to imaging centers of Yazd hospitals. Methods: A cross-sect...

[ 4 ] - Physicians’ awareness in Yazd province about Biological Effects of ionizing radiation applied in radiological imaging procedures

Introduction: Ionizing radiation has long-term risks, especially cancer. Since physicians request radiological examinations for patients, they need to be aware of its benefit and also risks. The aim of this study was to assess the overall knowledge of physicians in Yazd province about the radiation risks associated with diagnostic imaging procedures. Material and Methods: In this descriptive ...

[ 5 ] - Assessment of radiation-induced cancer risk to patients undergoing computed tomography angiography scans

Background: Computed tomography angiography (CTA) scan is a suitable imaging technique to evaluate the blood vessels. However, one major disadvantage is the potential risk of cancer related to ionizing radiation exposure during the procedures. The aim of this investigation was to estimate the risk of exposure induced cancer death (REID) values for some common computed tomography angiography (CT...

[ 6 ] - Evaluation of radiation-induced cancer risk to patients undergoing intra-oral and panoramic dental radiographies using experimental measurements and Monte Carlo calculations

Background: Radiation doses associated with the conventional dental radiographies are relatively low, but their number is high. Therefore, justification is necessary to ensure that radiation doses to patients, particularly children, are kept as low as reasonably achievable. Materials and Methods: The exposure factors applied for real patients in four age groups (5, 10, 15-year-old and adult) we...

[ 7 ] - Image quality assessment in digital radiography systems- A Pehamed FLUORAD A+D phantom study

Introduction: The use of digital radiography systems has become more common all around the world. Ideal situation in radiography is to maximize the image quality while minimizing the patient dose. The purpose of this study was to compare image quality and radiation dose in different digital radiography systems. Materials and Methods: Images of Pehamed FLUORAD ...

[ 8 ] - Evaluation of Blood Parameters of the Medical Radiation Workers

Introduction: Medical workers in the departments of radiology, computed tomography, nuclear medicine, and radiotherapy are always exposed to ionizing radiations. Complete blood count (CBC) test is commonly used to monitor the health of radiation workers. The aim of this study was to evaluate the hematological parameters of radiation workers of Isfahan, Iran, and reveal...
