摘要:
In a method to determine the actual flip angle in magnetic resonance tomography with continuous table feed, at least one echo signal is generated by a pulse sequence from which an actual flip angle is produced with at least one RF pulse of the sequence, and a gradient scheme is used in the direction of the continuous travel of the examination subject, the gradient scheme being designed such that its first moment disappears at the points in time of each echo signals used for the determination of the flip angle. Such a pulse sequence is also used in a method for adjustment of the transmitter voltage for RF pulses given continuous travel of the examination subject in a magnetic resonance apparatus.
