Balanced steady-state free precession (bSSFP) has merits such as high signal-to-noise ratio, T2/T1 contrast and rapid acquisition speed. However, bSSFP requires further acceleration in 3D imaging due to massive data collected. The acceleration of conventional parallel imaging techniques is limited. In this study, we propose wave-bSSFP by using a modified wave-CAIPI technique to highly accelerate bSSFP. Wave gradients were truncated to further reduce g-factor noise penalty with high wave amplitudes. The simulation and in vivo experiment indicate that wave-bSSFP is effective in decreasing g-factor. Here, an acceleration factor of 9 was achieved in brain scan with 0.8 mm isotropic resolution.
