Precise coordinates of trajectories are essential for image reconstruction of k-space data acquired from non-rectangular trajectories, and measurement of the trajectories often requires prescan calibration that complicates the process. This abstract presents a simple and effective method to estimate the coordinates of non-rectangular periodic trajectories from normal scan data and demonstrates its efficacy in image reconstruction of in vivo scan data acquired from ZIGZAG trajectory.
