1. A magnetic resonance imaging system for acquiring magnetic resonance data from an imaging zone, wherein the magnetic resonance imaging system comprises: one or more computer processors configured for controlling the magnetic resonance imaging system to image a patient in an imaging zone of the magnetic resonance imaging system, the patient undergoing patient motion; and a memory configured for storing machine executable instructions for execution by the processor, wherein execution of the machine executable instructions causes the one or more processors to: control the magnetic resonance imaging system to repeatedly acquire the magnetic resonance data from the imaging zone, the magnetic resonance data including magnetic resonance anatomic image data and magnetic resonance navigator data; create a set of navigator vectors from the magnetic resonance navigator data; construct a dissimilarity matrix by calculating a metric indicative of a dissimilarity between each navigator vector of the set of navigator vectors; determine a matrix classification of the dissimilarity matrix using a classification algorithm, the matrix classification being indicative of patient motion; control the magnetic resonance imaging system to modify acquisition of the magnetic resonance data based on the determined matrix classification; and reconstruct the magnetic resonance anatomic image data into at least one anatomic image; and a display device configured to display the at least one anatomic image.
