The FOV of Propeller MRI is approximately circular due to the rotating blade sampling pattern in the k-space, causing within-FOV aliasing artifact. In this article we proposed a self-training method similar to kt-Blast to restore the aliasing artifact to the conventional rectangular FOV. Phantom experiments were performed to verify the proposed method. Results show good agreement with conventional Cartesian sampling.
