Abstract
An MR imaging method and apparatus especially adapted for invivo cardiac MR imaging, rejects data acquired during periods of arrhythmia while maintaining the magnetic fields and pulsing of the RF coils during such periods. Data acquisition is resumed after M cycles of regular period, and after remeasuring the data acquired during N cycles prior to the occurrence of the arrhythmia, where M and N are integers preferably from 1 to 5. The average timing can periodically be recalculated in order to compensate for slow changes in cardiac rate.
