Task-Based Optimization of Computed Tomography Imaging Systems [article]

Adrian A. Sanchez
<span title="2015-05-14">2015</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
The goal of this thesis is to provide a framework for the use of task-based metrics of image quality to aid in the design, implementation, and evaluation of CT image reconstruction algorithms and CT systems  ...  However, due to the demonstrated importance of optimization-based algorithms in a wide variety of CT applications, we devote one chapter to the characterization of noise properties in TV-based iterative  ...  Low contrast visibility is consistently improved with heavier filtering, while the higher-contrast inserts are arguably equally visible in each image.  ...
