K_x-K_y-t-space trajectory for single-shot spatial-spectral encoding. Phase encoding lines are measured with k_y-spacing RΔk, where R(=4) denotes the acceleration factor. Target k_y-spacing after SENSE reconstruction is Δk. Each readout module, which consists of 4 forward and 4 reverse k_x-k_y-space encoding segments, is traversed forward and backward, and repeated N-times with spacing Δt to encode N spectral points. Data are only collected during the horizontal segments of the trajectory.
