A real-time, self-gated spiral flow imaging sequence using a sliding window phase matching reconstruction is proposed. The acquisition for reversed flow encodings was separated into a negative reference block and a positive acquisition block. View-shared reconstruction in each block was performed before phase contrast images were generated using a novel sliding window phase matching algorithm for self-gating. Experiments on normal volunteers and under different breathing conditions show that the proposed method can accurately quantify blood flow in real time.
