Rapid 3D Parallel Imaging of Non-Cartesian Data

Nicholas Ryan Zwart¹, James Grant Pipe¹

A 3D parallel imaging reconstruction technique is presented. This technique is a coil sensitivity based method used for reconstructing undersampled arbitrary 3D k-space trajectories. Iterations enforce receive b1-field and sampled data consistency without degridding/gridding operations improving the computational speed compared to similar reconstruction methods. The 3D trajectory used is Spiral Projection Imaging.
