A novel method is presented for real-time phase contrast (PC) cardiovascular flow imaging. It integrates a real-time data acquisition scheme (without ECG gating and respiration control) with constrained reconstruction using joint low-rank and sparsity constraints. It achieves a temporal resolution of 34.4 msec and spatial resolution of 2.58 mm in a 2D real-time flow imaging experiment with three velocity encoding directions. The method should prove useful for real-time cardiovascular flow imaging.
