Gradient imperfections such as gradient delay can cause image distortion and artifacts in UTE imaging. In this work, we report an iterative gradient delay correction method for 3D UTE imaging that allows use of arbitrary gradient waveform model, independent calibration of x, y, and z gradients, and subject-specific delay correction with an embedded prescan. The feasibility of improved image quality using this proposed method was demonstrated by volunteer data.
