The radial continuous sampling sequences (aka Total Sampling Time (TST) acquisitions) are more time efficient than their Cartesian counterparts, however radial sequences exhibit characteristic artifacts. This study proposes a TST sequence where the phase encoding and dephase/rephase lobes are overlapped in order to create a hybrid radial/Cartesian trajectory bowtie. This TST sequence, named Broad Over-sampling With TIme Efficiency (BOWTIE), samples during the traditionally unsampled radial traversal to and from the edge of k-space before and after Cartesian readout. In this study, a BOWTIE sequence was developed for imaging both phantoms and human volunteers for the purpose of SNR gain.
