Improved 3D Radial Phyllotaxis Trajectories for Uniform Density Distribution of Readout Directions and Sequential Binning
This paper introduces improved 3D radial phyllotaxis trajectories, specifically UPhy and FlexiPhy, which achieve uniform readout direction density and utilize randomized interleave ordering to significantly reduce ringing artifacts and enhance the robustness of retrospective sequential binning in dynamic MRI.
