Adaptive Sampling for Linear Sensing Systems via Langevin Dynamics
Guanhua Wang, Douglas C. Noll, Jeffrey A. Fessler
Adaptive or dynamic signal sampling in sensing systems can adapt subsequent sampling strategies based on acquired signals, thereby potentially improving image quality and speed. Th…
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…
B-spline Parameterized Joint Optimization of Reconstruction and K-space Trajectories (BJORK) for Accelerated 2D MRI
Guanhua Wang, Tianrui Luo, Jon-Fredrik Nielsen +2
Optimizing k-space sampling trajectories is a promising yet challenging topic for fast magnetic resonance imaging (MRI). This work proposes to optimize a reconstruction method and…
