The Software and Hardware Acceleration for Interior Tomography
The x-ray CT is with high spatial resolution, temporal resolutions, and high-speed imaging characteristic. The iterative reconstruction algorithms are becoming more important since they can reconstruct better image qualities from incomplete projection data compared to analytical reconstruction …

Development of Novel Cardiac CT Methods
… To address these issues, the methods of interior tomography, compressive sensing based algorithms, knowledge-based dynamic volumetric cardiac CT, and controlled cardiac CT were developed along with novel trajectories like saddle curves and composite-circling scanning. Interior tomography …

Compressed Sensing based Micro-CT Methods and Applications
High-resolution micro computed tomography (micro-CT) offers 3D image resolution of 1 um for non-destructive evaluation of various samples. However, the micro-CT performance is limited by several factors. Primarily, scan time is extremely long, and sample dimension is restricted by the x-ray beam …

A Scheme for Ultra-Fast Computed Tomography Based on Stationary Multi-Beam X-ray Sources
The current cardiac computed tomography (CT) technology is mainly limited by motion blurring and radiation dose. The conceptual multi-source interior CT scheme has provided a potential solution to reduce motion artifacts and radiation exposure. This dissertation work conducted multi-facet …
