Reference-Free Parallel Imaging with Phase Scrambling (PIPS)

Maxim Zaitsev¹, Jrgen Hennig¹

A combination of phase-scrambled MRI using a quadratic phase modulation with traditional parallel imaging methods is presented demonstrating a possibility of a full FOV full resolution image reconstruction based on the undesampled k-space data alone, without requiring neither prior knowledge of coil sensitivity maps nor additional auto-calibrating k-space lines.
