Magnetresonanz (MRI)-Abbildungssystem mit zeitlich veränderlichem Gradienten während der Signalerfassung

摘要

An NMR system acquires data during the application of a readout gradient that varies in amplitude. The NMR signal is sampled uniformly in time and is mapped to NMR data which is sampled uniformly in k-space by a digital filter. Sets of stored filter coefficients adapt the digital filter to different readout gradient waveforms and different fields of view and image resolution.
