For whole-heart coronary MRA, we are developing a
sequence based on alternating-TR SSFP and 3D cones
k-space sampling. For SSFP imaging, the order in which
each readout is acquired must be carefully chosen to
avoid eddy current effects. In this work,
multidimensional golden means and phyllotaxis designs
were developed for the 3D cones trajectory to sample a
more distributed region of k-space during each heartbeat
without introducing eddy current artifacts. For
verification of signal quality and eddy current
reduction, these methods were compared to the default
sequential ordering.
