Abstract
To image flowing materials, magnetic resonance preconditioning pulses are applied in an upstream region ( ). For scanning a subject, an RF pulse calibration sequence is performed by generating a corresponding magnetic resonance data line ( ) in each of a plurality of slices ( ) along a vessel. A processor ( ) determines a signal intensity for each slice ( ), fits the intensities for the family of slices to a curve ( ), and adjusts an RF pulse profile with spatial position in accordance with the curve which is dynamically dependent on the scanned subject. In a subsequent imaging sequence with the adjusted tip angles, data lines from each of the slices are received ( ) and reconstructed ( ) into an image representation stored in the memory ( ).
