Optimization of Parameters in 16-slice CT-scan Protocols for Reduction of the Absorbed Dose
Introduction In computed tomography (CT) technology, an optimal radiation dose can be achieved via changing radiation parameters such as mA, pitch factor, rotation time and tube voltage (kVp) for diagnostic images. Materials and Methods In this study, the brain, abdomen, and thorax scaning was performed using Toshiba 16-slice scannerand standard AAPM and CTDI phantoms. AAPM phantom was used for...
متن کاملRadiation dose reduction with hybrid iterative reconstruction for pediatric CT.
PURPOSE To assess image quality and radiation dose reduction with hybrid iterative reconstruction of pediatric chest and abdominal computed tomographic (CT) data compared with conventional filtered back projection (FBP). MATERIALS AND METHODS A total of 234 patients (median age, 12 years; age range, 6 weeks to 18 years) underwent chest and abdominal CT in this institutional review board-appro...
متن کاملIterative reconstruction algorithms for dose reduction in Micro-CT
Aims In preclinical setting, micro-CT is used to provide anatomical information of small animals (e.g. mice), and can be used in conjunction with functional imaging modalities, which provide information on biological processes in tissues. The combination of micro-CT with functional imaging provides localization of the investigated process, i.e. physiology or disease, within the animal and furth...

متن کاملRadiation dose reduction in temporal bone CT with iterative reconstruction technique.
BACKGROUND AND PURPOSE Iterative reconstruction of CT images is characterized by reduced image noise and may allow reduction in radiation exposure. We investigated the influence of an IRT technique on image quality and radiation dose savings when applied to temporal bone CT. MATERIALS AND METHODS Based on the typical image quality level of adult subjects using routine radiation dose and FBP, ...
