A flexible 3D “Spiral Staircase” (SSC) trajectory is introduced that reduces g-factor losses from through-plane parallel imaging acceleration, regardless of coil geometry. Results demonstrate up to a 5x g-factor improvement over Cartesian SENSE for through-plane acceleration in axial brain acquisition with R = 3.
