With the advent of complex and precise radiation therapy techniques, use relatively small fields is needed. Using such field sizes can cause uncertainty in dosimetry; therefore, special attention required both dose calculations measurements. There are several challenges small-field dosimetry as steep gradient field, volume averaging effect, lack charged particle equilibrium, partial occlusion source, beam alignment, unable to a reference dosimeter. Due these challenges, dosimeters needed for...
Purpose: Nowadays, the use of polymer composites with several metals to design and build new radiation composite shields practical features in radiology is expanding. Materials Methods: Three metal oxides, including Bismuth oxide (Bi2O3), Tungsten (WO3), Tin (SnO2) were used as mono-metal bimetallic compound silicon matrixes for clarification their use. Monte Carlo simulation methods enter specifications each combination silicon. The mass attenuation coefficients mono- calculated energy...
BackgroundTo reduce the risk of errors, patient safety monitoring in medical imaging department is crucial. Interventions are required and these can be provided as a framework for documenting, reporting, evaluating, recognizing events that pose threat to safety. The aim this study was develop minimum data set dashboard adverse eventsMaterial methodsThis developmental research conducted multiple phases, including content determination using Delphi technique; database designing SQL Server;...
To evaluate the ability of glycyrrhizic acid (GLA) to reduce tumor necrosis factor α (TNF-α), release on messenger ribonucleic (mRNA) and protein production in lungs using GLA response irradiation were studied. The animals divided into four groups: No treatment (NT group), only (GLA (XRT plus (GLA/XRT group). Rats killed at different time points. Real-time reverse transcriptase polymerase chain reaction (RT-PCR) was used mRNA expression TNF-α (compared with non-irradiated lungs). An...
Abstract Purpose In this study, we evaluated the renal protective effects of montelukast (MLK) against ionizing radiation (IR) induced nephrotoxicity in mice. Materials and Methods Radioprotective MLK were assessed by biochemical analysis including measurements kidney malondialdehyde (MDA), reduced glutathione (GSH), serum creatinine urea levels. Besides, for further evaluation on system, 99m Tc‐dimercaptosuccinic acid (DMSA) has been applied. The total antioxidant capacity was measured...
Bismuth shield has been recently introduced for radiation protection of patient radiosensitive organs such as breast during chest CT with image diagnosis capability. The purpose this study was to evaluate the dose reduction and quality conserve using new bismuth-silicon composite shields CT. Scans were performed on a PMMA phantom 6-slice MDCT system. Dose calculated by placing ion-chamber in 12 o’clock position measuring. Chest scans without bismuth 10% 0.5 mm 1 thicknesses. Image assessed...
Background: Radiotherapy of the thorax often causes lung inflammation leading to fibrosis. Objectives: The aim this study was investigate whether use glycyrrhizic acid (GLA) could improve development fibrosis in irradiated animals. Materials and Methods: Wistar rats were divided into four groups. Group A received thoracic irradiation. Rats group B GLA C no D administered at a dose 4 mg/kg body weight using an intraperitoneal injection one hour before Radiation therapy delivered on Cobalt-60...
↑What is "already known" in this topic:Understanding natural background radiation level, as the major source of human exposure to ionizing important because its impact on health.A number studies have assessed level many countries. →What article adds:In study, data showed that all cities 2 provinces Hormozgan and Sistan-Bluchestan had a lower than worldwide level.This study can be used reference for research design development regional surveys associated with measurement southeast Iran.
Ionizing radiation is present in all environment of the Earth's surface, beneath Earth and atmosphere. Human beings are exposed to external from their surroundings naturally also internal food, water air they consume. Then, it important measure develop knowledge about radiation.This study designed evaluate risks outdoors indoors hot spring Gachine area Bandar Abbas.The device used this cross sectional was environmental surveymeter. Indoor gamma carried out inside 115 dwellings. Measurement...
Background: Acinetobacte is the leading cause of pneumonia and sepsis in ICU ward. Accordingly, present study, antibiotic susceptibility pattern, presence, dissemination different classes integrons fluoroquinolone resistance genes were investigated among A. baumannii isolates. Methods: In this descriptive, cross-sectional during a period 24 months (2018 - 2020), 100 isolates isolated from clinical specimens patients admitted to two teaching hospital Ardabil province northwest Iran. Kirby...
Introduction: The world's population is aging and the issue of sexual activity in elderly people still a taboo many cultures. purpose this study was to examine activity, interest satisfaction older women attended Health Care Centers city Ardabil-Northern Iran. Method This Cross-sectional conducted on 380 married over 60 years old who had been selected by convenient sampling method. Data were gathered anonymously three questionnaires (Goldberg general health, FSFI demographic information...
