متن کاملA Phantom Study for the Optimization of Image Quality and Radiation Dose for Common Radiographic Examinations in Digital Radiography
Introduction: Phantom studies facilitate the implementation of radiation dose surveillance as a function of radiographic technical parameters for minimizing patient radiation dose. The evidence of such investigations can then be used to evaluate technical parameters used in the radiographic procedures to reduce radiation dose without compromising the image quality. Material and Methods: This ex...
متن کاملOptimization of Dose and Image Quality in Full-fiand Computed Radiography Systems for Common Digital Radiographic Examinations
IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...
متن کاملComparison of Accuracy and Observer Agreement in the Detection of Simulated External Root Resorption Using Conventional Digital Radiography and Digitally Filtered Radiography
Introduction: External root resorption is a clinical problem that often cannot be detected clinically. Thus, radiography plays a crucial role in its diagnosis. However, optimal radiographic quality with minimal radiation exposure {2.1 [EN] Verify English word/phrase choice} is an important factor in selecting the appropriate radiographic technique. The aim of this study was the comparison of ac...
متن کاملEffective Dose Evaluation of Critical Organes in Digital Radiography Exames
Background and Aim: Due to the increasing number of radiographic tests, TLD dosimeters can be used to measure the effective dose of critical organs in various radiographic tests. In this research, the progression of analogue to digital radiology devices, which facilitates and accelerates the performance of radiographs, especially emergency patients, was investigated, and then the effective dose...
متن کاملبررسی میزان تکرار تصاویر رادیوگرافی دیجیتال و عوامل مرتبط با آن در مراکز درمانی بخش های دولتی شهرستان ساری در سال 1396
Background and purpose: The radiographic imaging repeat rate (RR) in digital and conventional imaging systems is considered as a quality control indicator. RR increases the unnecessary patient and staff dose, prevents the loss of resources and depreciation of systems and increases the time for radiographic services. In this study, digital radiographic RR and its related factors were inv...
