Reconstruction of high-quality ultrashort echo-time UTE images requires precise knowledge of the dynamic gradient magnetic fields used to perform the spatial encoding during the ramp up of the gradients. System delays and eddy currents can perturb the gradient fields and significantly degrade the image quality. The present study proposes the measurement of the gradient transfer response function with standard scanner hardware to correct the UTE readout gradients and to improve UTE image quality.
