Abstract
The invention concerns a method for correcting linear field inhomogeneities in a magnetic resonance apparatus. After an excitation pulse and application of a phase gradient in a predetermined direction, a data point is taken after a fixed, predetermined time t . This is repeated for systematically changed strengths of the phase gradient and constant t . The phase gradient with maximum measuring signal corresponds to a field correction gradient in the corresponding direction.
