1. A method for avoiding artifacts in measurement data captured using a magnetic resonance system which includes a gradient unit, the method comprising:
loading data which characterizes the gradient unit of the magnetic resonance system;
loading a measurement protocol to be used for capturing the measurement data, wherein the measurement protocol includes gradients to be switched and radio frequency (RF) excitation pulses and RF refocusing pulses to be irradiated,
wherein, after irradiation of an RF excitation pulse, a train of at least two RF refocusing pulses is irradiated, and the measurement data is captured after each RF refocusing pulse; and
determining compensation gradients which, after the capture of the measurement data, are to be switched after a final RF refocusing pulse of the train of RF refocusing pulses associated with the RF excitation pulse and before a following RF excitation pulse as a function of the measurement protocol and of the data which characterizes the gradient unit; and
carrying out the measurement protocol using the compensation gradients.
