Synthetic Target (ST) is a rapid self-calibrated parallel reconstruction method. The original ST works well for spiral and Cartesians, yet suffers from aliasing for radial trajectories. In this abstract, we improved our original Synthetic Target algorithm by adding a phase constraint in the training process. The resultant images have higher SNR than the original ST for radial trajectories. We also compared our method with another iterative parallel reconstruction algorithm in terms of image quality and computation time.
