In this study, we demonstrate a new non-Cartesian trajectory scheme to reduce clustering of trajectory arms during CINE reconstruction, while still allowing for real-time reconstructions. In this scheme, trajectory arms are incremented within temporal blocks and additional angles are played between blocks. These added angles are optimized to perturb trajectory coherence during CINE reconstruction, as demonstrated through simulations showing reduced clustering and improved CINE image quality.
