摘要:
In a method and apparatus for recording magnetic resonance (MR) signals from an examination object, raw data space is filled with MR signals in raw data lines. Movement information of the examination object is detected during recording of the MR signals and the movement information is grouped into different movement phases of the examination object. A temporally randomly distributed sequence of the recording of the raw data lines is determined, with which at least one predetermined portion of the raw data space is filled MR signals. The MR signals are acquired in the determined temporally randomly distributed sequence of the raw data lines in the predetermined portion. Each recorded raw data line is allocated to one of the movement phases of the examination object.
