Abstract

A method for acquiring a magnetic resonance data set of an object under examination by a magnetic resonance system using a scan sequence is provided. The scan sequence includes a succession of sequence blocks, and in each sequence block, there is at least one sub-block including an excitation section and/or a detection section. An excitation section includes at least one excitation pulse, and in a detection section, an echo signal or an echo train is acquired as a scan signal. At least one item of motion information is provided for each sub-block. The motion information contains information about a movement of the object under examination within a duration of the sub-block. Some of the sub-blocks are automatically repeated. At least the sub-blocks having motion information that exceeds a threshold value are repeated. The threshold value defines a motion amplitude.
