FIG. 3.

Readout gradient (solid line) with corresponding first-moment trajectory (dashed line) for a flow-compensated line in k-space (a). The trajectory in k-t-space for two separate TRs (b). For visualization, a projection in the k_x-k_y plane is shown. Projections are repeated in separate TRs, as shown by solid and dashed lines, such that projections at the same angle have the same first-moment offset and trajectory in k-t-space. Black lines indicate the first echo and gray lines indicate the second echo.
