Abstract Purpose While O-Space imaging is well known to accelerate image acquisition
beyond traditional Cartesian sampling, its advantages compared to undersampled radial
imaging, the linear trajectory most akin to O-Space imaging, have not been detailed. In
addition, previous studies have focused on ultrafast imaging with very high acceleration
factors and relatively low resolution. The purpose of this work is to directly compare O-Space
and radial imaging in their potential to deliver highly undersampled images of high …
