Abstract
In a magnetic resonance imaging system, MRI data acquisition sequences are repeatedly and alternately executed for (a) a diagnostic image and (b) a navigator image that is an image for motion detection. Each subsequent navigator image is analyzed to detect the position of a mark indicating the position of a slice excited by the prior execution of a diagnostic imaging sequence. The respiratory motion of a portion of the subject is estimated based on the detected position of the mark.
