Abstract

In trigger-adapted MR data acquisition, a trigger from the object undergoing investigation is detected, by which a periodically repeated procedure of the object is detected. An imaging sequence is performed multiple times dependent on the trigger in order to acquire MR data. The imaging sequence includes at least one preparation pulse and a subsequent readout module, the readout module ending a first time period before an end of the procedure. The respective imaging sequence is performed only if RR≥RR(0)−(dRR−dRR(B1)), wherein dRR(B1) is a second time period, RR corresponds is a first time interval between a trigger that is currently being detected and a trigger that was detected immediately before the currently detected trigger, and RR(0) is a second time interval that corresponds to a predefined time interval between two directly succeeding triggers.
