ABSTRACT:
In a nuclear magnetic resonance tomography apparatus wherein image information are sampled in time measurement windows with a sampling grid that is not equidistant in time and are digitized, for D.C. offset compensation in at least one measurement window, the output signal of the measurement channel is sampled without a nuclear magnetic resonance signal, is digitized, and the offset data acquired in this way are stored in an offset vector. The n offset data stored in the offset vector are subtracted from the image raw data that are acquired per measurement window and allocated chronologically in the sampling grid.
