Stochastic Optimization of 3D Non-Cartesian Sampling Trajectory (SNOPY)
Guanhua Wang, Jon-Fredrik Nielsen, Jeffrey A. Fessler +1
Optimizing 3D k-space sampling trajectories for efficient MRI is important yet challenging. This work proposes a generalized framework for optimizing 3D non-Cartesian sampling patt…
Off-resonance artifact correction for magnetic resonance imaging: a review
Melissa W. Haskell, Jon-Fredrik Nielsen, Douglas C. Noll
In magnetic resonance imaging (MRI), inhomogeneity in the main magnetic field used for imaging, referred to as off-resonance, can lead to image artifacts ranging from mild to sever…
Paying U-Attention to Textures: Multi-Stage Hourglass Vision Transformer for Universal Texture Synthesis
Shouchang Guo, Valentin Deschaintre, Douglas Noll +1
We present a novel U-Attention vision Transformer for universal texture synthesis. We exploit the natural long-range dependencies enabled by the attention mechanism to allow our ap…
