Abstract
A pulse sequence is disclosed for a nuclear magnetic resonance tomography apparatus wherein the scans are executed with a non-constant repetition time, such as due to ECG triggering. Normally, the non-constancy of the repetition time in a nuclear magnetic resonance tomography apparatus results in a deterioration of the quality of the images, due to eddy currents. In the pulse sequence disclosed herein, gradient pulses having a chronological mean value are inserted in the pause between two successive scans, this chronological mean value being equal to the chronological mean value of the corresponding gradients during the scans. The disturbing influence of variable repetition times on the image quality is thus eliminated.
