1. A method for magnetic resonance imaging (MRI) comprising the steps of:

  • a) specifying a scanning path;

    b) determining gradient amplitude directly as a function of arc-length along the specified scanning path in k-space, rather than as a function of time;

    c) calculating a time optimal gradient waveform for scanning the scanning path from the gradient amplitude; and

    d) scanning along the scanning path using the time optimal gradient waveform.
