Abstract:
A method for producing a magnetic field gradient pulse with an Magnetic Resonance Imaging (MRI) system, the steps comprising:a) inputting a set of scan parameters which define a prescribed pulse sequence for acquiring image data with the MRI system;b) calculating the area of a magnetic field gradient pulse using at least one of said scan parameters;c) calculating the peak gradient amplitude and slew rate of a triangular gradient pulse having the calculated area of the magnetic field gradient pulse, and in which the slew rate does not exceed a physiologic slew rate limit calculated relative to the gradient amplitude of the triangular pulse; and,d) producing a magnetic field gradient pulse during the performance of said prescribed pulse sequence by the MRI system, the gradient pulse having a minimum duration based on the calculated peak gradient amplitude and the slew rate.
