METHOD FOR ACCELERATED MAGNETIC RESONANCE IMAGING USING UNIVERSAL CALIBRATION DATA FOR VARYING K-SPACE SAMPLING

摘要

Method for operating a magnetic resonance device (9) when recording magnetic resonance data using a recording technique in which the Cartesian scanning of the k-space (1), in particular by rotating gradient directions around the k-space center (6), one for each recording section Part of the magnetic resonance data is carried out differently, the recording technique being combined with an accelerating imaging technique for which a reference area (3, 3 ', 3 ") around the k-space center (6) is used for each individual layer to be scanned, whereby , in particular at the beginning of the recording, a calibration range (7) of the k-space (1) comprising all reference areas (3, 3 ', 3 ") required in the course of the recording is determined and a calibration data record of the k-space (1) with the Magnetic resonance device (9) by complete, Cartesian scanning of the calibration area (7) in a calibration m measurement is recorded, reference data for each recording section being determined from the calibration data record.
