Iterative Image Reconstruction for Sparse-View CT Using Normal-Dose Image Induced Total Variation Prior
X-ray computed tomography (CT) iterative image reconstruction from sparse-view projection data has been an important research topic for radiation reduction in clinic. In this paper, to relieve the requirement of misalignment reduction operation of the prior image constrained compressed sensing (PICCS) approach introduced by Chen et al, we present an iterative image reconstruction approach for s...
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 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 کاملModel-based iterative reconstruction and adaptive statistical iterative reconstruction: dose-reduced CT for detecting pancreatic calcification
BACKGROUND Iterative reconstruction methods have attracted attention for reducing radiation doses in computed tomography (CT). PURPOSE To investigate the detectability of pancreatic calcification using dose-reduced CT reconstructed with model-based iterative construction (MBIR) and adaptive statistical iterative reconstruction (ASIR). MATERIAL AND METHODS This prospective study approved by ...
متن کاملIterative image reconstruction techniques: Applications for cardiac CT.
BACKGROUND Traditional limitations of cardiac CT are related to image noise, blooming artifacts from calcifications and stents, and radiation exposure. We evaluated whether these limitations can be ameliorated by the use of iterative reconstruction in image space (IRIS) instead of traditional filtered back projection (FBP) image reconstruction techniques. METHODS We compared image reconstruct...
