摘要：
The degree of sub-sampling in magnetic resonance imaging is such that the ensuing acquisition time for receiving (echo) series of magnetic resonance signals due to an individual RF excitation is shorter than the decay time of such magnetic resonance signals. Preferably, a segmented scan of the k space is performed, the number of segments and the number of lines scanned in each segment being adjustable and a predetermined total number of lines being scanned. Preferably, a small number of segments is used such that the acquisition time for receiving the magnetic resonance signals for the complete magnetic resonance image is shorter than the process time of the dynamic process involved.
