Abstract:
1. A method for acquiring magnetic resonance data from an examination subject wherein unwanted signal components are suppressed, comprising: (a) acquiring a physiological signal from an examination subject located in a magnetic resonance data acquisition unit, and detecting data points of said physiological signal; (b) in a computerized processor, evaluating a trigger condition dependent on the detected physiological data points; (c) operating said data acquisition unit to execute at least one preparation module that suppresses unwanted signals in a time period in which said data points of said physiological signal are still being acquired thus said trigger condition has not yet been satisfied; (d) after said trigger condition is satisfied, operating said magnetic resonance data acquisition unit by starting a data acquisition phase of a predetermined duration, comprising at least two preparation modules substantially corresponding to the at least one preparation module implemented in (c), to suppress unwanted signals, followed by a data acquisition module in which magnetic resonance measurement data are acquired; and (e) after said acquisition phase, repeating (a) through (d) until all desired magnetic resonance measurement data of the examination subject have been acquired, while maintaining a same time interval between any two successive preparation modules, said time interval starting after said at least one preparation module in (c) and continuing until an end of the acquisition phase in (d).
