Abstract

The invention relates to a method for processing a plurality of cardiac MR data sets where the plurality of cardiac MR data sets which were acquired over a plurality of cardiac cycles are provided, each cardiac MR data set having a corresponding time stamp at which the corresponding cardiac MR data set was acquired, wherein each of the cardiac MR data sets was acquired based on a trigger event. A series of time differences is determined between the acquisitions of the cardiac MR data sets based on the time stamps, and a default time difference representing the time difference between 2 consecutive cardiac MR data sets is determined which were acquired using correct trigger events. In the time differences, at least one pair of incorrect time differences is determined in the series of time differences, each incorrect time difference representing the time difference between 2 consecutive MR data sets in which at least one MR data set from the 2 consecutive MR data sets was acquired using an incorrect trigger event. Approved MR data sets are determined comprising only cardiac MR data sets from the plurality of cardiac MR data sets which were acquired using the correct trigger event, based on the at least one pair of incorrect time differences and the approved MR data sets are further processed.
