(A) Schematic representation of the continuous acquisition, on the left, with an example of a 3D trajectory of one k-space segment (top hemisphere) on the right. The SI readout used for respiratory self-navigation is highlighted in red. Each data segment is rotated with the golden angle with respect to the previous one. (B) Example of the binning of the readouts for one cardiac phase: 1) Data originating from a specific time interval (100 ms width) after the R-wave are grouped together (blue); 2) respiratory self navigation is then applied and a 3D cine frame reconstructed. 3) This is repeated multiple times each 50 ms for full coverage of the cardiac cycle. 4) The period of most quiescent coronary motion was identified and data coming from this time interval are used to reconstruct the final, static coronary MRA dataset.
