The proposed (k, t)-space sampling scheme. Here the temporal training data are acquired from the central k-space, while the imaging data are acquired from the outer k-space. The same sampling pattern is applied for the flow-compensated and flow-encoded data sets. Temporal interpolation is performed to ensure the training data are at the time instants as the imaging data. Note that with this sampling scheme, the (nominal) temporal resolution is 2 × N _v  × TR
