[ 1 ] - Design and Fabrication Process of CT number Linearity and Homogeneity Phantom CT Scan
Introduction: One of the most valuable goals of phantoms, replacing with human goals in the field of research and quality control of diagnostic X-ray systems. There are various algorithms and methods for obtaining Homogeneity and CT number linearity for CT scan device. One of the most famous of these methods, the method is to use a uniform and homogeneous environment to comput...
[ 2 ] - 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...
[ 3 ] - Design and Fabrication Process of MTF Phantom CT Scan
Introduction: One of the main steps in the optimization process in diagnostic imaging is the quality control of radiology devices. The usual method of CT scan calibration is used of a phantom. The phantom created a certain weakening for the radiation through which it passes. One of the most suitable methods for quantitative analysis of the resolution and contrast in CT scan im...
[ 4 ] - Primary efforts to optimize image quality in chest direct digital radiography of pediatric patient (for the age group 0 to 1 and 1 to 5 years) with survey some effective parameters in image quality and patient dose
Introduction: This study, evaluate pediatric digital radiography. Due to the high rates of this test and the high sensitivity of children to ionizing radiation in comparison with adults, it is attempted to achieve near optimal conditions by reducing the dose and maintaining the image quality. The object of the study is to change the irradiation parameters such as kV and mA and ...
