In their investigations, radiofrequency pulse designers often use flip angle measurements to validate their new developments. However when the objective is to implement true target matrix rotations, as for instance in the spin-echo sequence, those measurements inform about the performance of the RF pulse only for a particular input state. For the first time in MRI, we report the implementation of a Quantum Process Tomography experiment at 7 Tesla in order to characterize a transmit-SENSE 180 refocusing RF pulse, thereby providing information about the performance of the operation regardless of the input state.
