Self-calibrated Trajectory Estimation and Signal Correction Method for Robust Radial Imaging Using GRAPPA Operator Gridding (GROG)
PURPOSE: In radial imaging, projections may become miscentered due to gradient errors such as delays and eddy currents. These errors may result in image artifacts and can disrupt the reliability of DC-navigation. The proposed parallel-imaging-based technique retrospectively estimates trajectory erro...
