Partial Fourier acquisition has been widely combined with other acceleration techniques, i.e. Parallel imaging, Compressed sensing etc., to reduce MR scanning time. The k-space central data used for phase correction are crucial for the reconstructed image quality. However, these central data are usually acquired in a simple rectangular pattern, which leads to some problems in 3D MRI. A round pattern for partial Fourier acquisition is presented. Its advantages are also shown with in vivo experiments.
