Multiband
imaging allows for multiple simultaneously acquired slices, thus giving an
SNR benefit over conventional slice selection without potential artifacts
from secondary phase encoding. While
methods have been shown that can separate the slides using parallel imaging
for Cartesian trajectories, these methods are not compatible with non-Cartesian
sampling. Here we demonstrate the
possibility of reconstructing two simultaneously acquired radial slices using
an acquisition/reconstruction method known as radial CAIPIRINHA. We show that
this method is capable of higher accelerations than possible with comparable
Cartesian trajectories.
