The applications of dynamic compressed sensing MRI include cardiac imaging, fMRI, angiography, and perfusion imaging. Recently, by exploiting the diversities in coil sensitivity maps across the z-slice, simultaneous multislice imaging (SMS) or multi-band imaging (MB) have been extensively investigated for accelerated acquisition in brain imaging studies. By synergistically combining the two approaches, we propose a dynamic compressed sensing multi-band MR imaging technique for further acceleration in 3-D + t MR acquisition.
