Golden angle radial reordering (GA) could provide a
near-uniform k-space within a single reconstruction
window with arbitrary position and duration. However,
when applied with ECG-gated segmented acquisition where
a single reconstruction window breaks into several
temporally isolated k-space data, the k-space coverage
of GA may not be as uniform as GA without ECG gating.
Therefore, we sought to investigate the image artifacts
caused by applying GA to ECG-gated cardiac imaging and
propose a segmented GA method to address this issue.
