MRI with zero echo time and hard-pulse excitation (ZTE) enables efficient, silent, and robust 3D imaging of short-T2 samples. Data obtained with this scheme are slightly incomplete in the k-space centre due to the initial dead time that is caused by the finite length of the RF pulse, transmit-receive (T/R) switching, and digital filtering. In the present work, we report the first implementation of the ZTE approach for human applications, relying on rapid T/R switching in the s range.
