title: Ultra-fast brain MR imaging using simultaneous multi-slice acquisition (SMA) technique.
abstract: Whole-brain images were acquired with a 2X acceleration factor by using Simultaneous Multi-slice Acquisition (SMA). Utilizing a Sinc pulse modulated by cosine/sine functions combined with an extra gradient along the slice-selection direction during acquisition, we are able to take multiple magnetic resonance images of different slice simultaneously. 2-slice and 4-slice SMA experiments were also conducted to demonstrate the feasibility of this method; also a volumetric image of the phantom was taken, achieving an overall 3X acceleration.
