The combination of the PI with CS reconstruction has been an important research topic in MR community due to its potential for further acceleration in MR acquisition. In particular, the application to the 3D volumetric imaging has great potential due to the introduction of additional dimension along slice direction. In this work, we propose a combined approach of dynamic compressed sensing (CS) and parallel imaging (PI) for dynamic simultaneous multislice (SMS) imaging using multi-band RF pulses. The proposed algorithm is tested to dynamic contrast-enhanced angiography to observe brain tissue dynamics. SMS image of slice-direction acceleration factor of 2,4 and 8 with in-plane acceleration of 2 are reconstructed by the proposed multi-band dynamic CS algorithm. The reconstructed results show that a proper combination of CS and parallel imaging can effectively suppress noise propagation and provide improved spatio-temporal resolution under high acceleration factor. |
