Abstract: A method of controlling magnetic resonance (MR) image data acquisition includes generating a plurality of one-dimensional (1D) navigator profiles reflecting motion of an anatomic boundary region of an imaging subject over time at a measurement interval, and then generating a plurality of navigator image segments each for a corresponding 1D navigator profile of the plurality of 1D navigator profiles. A navigator image is then generated based on the plurality of navigator image segments, and a determination is made whether to acquire MR image data based on the navigator image.
