Abstract

Cardiac MR data sets are acquired over cardiac cycles and based on a trigger event, with each cardiac MR data set having a corresponding time stamp. A series of time differences is determined between acquisitions of the cardiac MR data sets based on the time stamps, and a default time difference representing the time difference between two consecutive cardiac MR data sets is determined, which were acquired using correct trigger events. A pair of incorrect time differences is determined, each incorrect time difference representing a time difference between two consecutive MR data sets in which at least one MR data set was acquired using an incorrect trigger event. Approved MR data sets are determined comprising cardiac MR data sets from the cardiac MR data sets which were acquired using the correct trigger event, based on the pair of incorrect time differences, and the approved MR data sets are further processed.
