magnetic gradient

An MRI term for the degree and direction of the linear rate of change of a magnetic field in space, which is one of three linear magnetisation waveforms superimposed on the main magnetic field at specific times within a pulse sequence to select the imaging region or provide necessary spatial localising information.
