(a) Sampling trajectories for the self-navigated 3D golden-angle UTE radial sequence, in which data acquisition is segmented into multiple interleaves that rotate by a golden angle. Half-spokes are acquired in a center-out fashion to achieve an ultra-short echo time. Each interleaf starts with a projection oriented along the superior-inferior direction (red lines) for self-navigation. (b-c) Two exemplary respiratory motion signals superimposed on their corresponding projection profiles, one for the NB-UTE acquisition (b), and the other for the NDB-UTE acquisition alternating between normal and deep breathing (c).
