Synopsis

Multi-slice two-dimensional turbo spin-echo (2D TSE) imaging is commonly used for its excellent in-plane resolution. However, multiple 2D TSE scans are acquired due to their poor through-plane resolution. In this study, we propose a novel slice-profile-based transformation super-resolution (SPTSR) framework for through-plane super-resolution (SR) of multi-slice 2D TSE imaging. We utilized a large clinical MRI dataset in this study. We demonstrate the effectiveness of our proposed SPTSR framework in 5.5x through-plane SR by both the visual comparison results and reader study results.
