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 کاملCompliance of Radiation Dose and Image Quality in a Nigerian Teaching Hospital with the European Guidelines for Pediatric Screen-Film Chest Radiography
Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be...
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 کاملEvaluation of a quality control phantom for digital chest radiography
RATIONALE AND OBJECTIVES To examine the effectiveness and suitability of a quality control (QC) phantom for a routine QC program in digital radiography. MATERIALS AND METHODS The chest phantom consists of copper and aluminum cutouts arranged to resemble the appearance of a chest. Performance of the digital radiography (DR) system is evaluated using high and low contrast resolution objects pla...
