Adaptation of the fundamental frequency of a hf excitation pulse which - in which not - selective excitation of the core pin signals in an examination subject

摘要

In the case of a method according to the invention for the not - selective excitation of the core pin signals in an examination subject by means of a magnetic resonance system, hf - excitation pulses for the excitation of the core pin signals in the examination subject, with simultaneous switching of gradient for spatial encoding of the excited nuclear spin signals, wherein the hf - excitation pulses are designed in such a way that the fundamental frequency of an arriving hf - excitation pulse which is adapted to the simultaneously switched gradient.By means of the dynamic adaptation of the irradiated hf - excitation pulses in each case connected to the same time, by means of artefacts gradients are not sufficiently excited nuclear spins in an examination region to be examined, in particular also in off - centre examination areas arranged, is avoided.Thereafter, a corresponding magnetic resonance system, a corresponding computer program product as well as a corresponding electronic data carrier is stressed.
