A method for designing the time dependence function k(t) for a given k-space trajectory k, where m stands for one or multiple of the spatial dimension indices x, y, or z, of a magnetic resonance imaging (=MRI) experiment carried out on an MRI system, wherein the trajectory kis generated by applying a time varying waveform g(t) of a gradient magnetic field, the method taking into account&#x2014;the gradient magnitude limit G and&#x2014;the gradient slew rate limit S of the MRI system, is characterized in that the method further takes into account a given frequency limit F in such a way that the gradient waveform g(t) does not contain frequency components above the frequency limit F which is characteristic for the gradient hardware of the MRI system. The invention provides a method for designing a time dependence function for a given k-space trajectory, which allows obtaining better quality MRI images.
