Abstract

A magnetic resonance scanner (10, 16) is configured to acquire a succession of magnetic resonance images of a subject at a frame rate and to measure one-dimensional projections passing through the center of k-space during the acquisition. A frame rate analyzer (30) is configured to determine a maximum temporal frequency from the measured one-dimensional projections. A controller (12) is configured to adjust the frame rate based on the determined maximum temporal frequency.
