Construction of an Equivalent Chest Homogeneous Phantom for Evaluation of Image Quality in Pediatric Radiography
Introduction: The purpose of this study is to build homogeneous equivalent phantom chest in order to provide the necessary ability for checking the image quality in radiographic tests in four age groups of children in terms of the most recent age group categorization ICRP103. This phantom provides the features of weakness and discrepancies similar to body and can be consi...
متن کاملEvaluation of a Noise Reduction Procedure for Chest Radiography
BACKGROUND The aim of this study was to evaluate the usefulness of noise reduction procedure (NRP), a function in the new image processing for chest radiography. METHODS A CXDI-50G Portable Digital Radiography System (Canon) was used for X-ray detection. Image noise was analyzed with a noise power spectrum (NPS) and a burger phantom was used for evaluation of density resolution. The usefulnes...

متن کاملPatient effective dose evaluation for chest X-ray examination in three digital radiography centers
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
