Abstract

A magnetic resonance (MR) imaging device repeatedly executes a navigator pulse sequence to generate navigator data in image space as a function of time, and a motion signal of an anatomical feature that moves with a physiological cycle as a function of time is extracted from the navigator data. A concurrent physiological signal as a function of time is generated by a physiological monitor concurrently with the repeated execution of the navigator pulse sequence. A gating time offset is determined by comparing the motion signal of the anatomical feature as a function of time and the concurrent physiological signal as a function of time. The MR imaging device performs a prospective or retrospective gated MR imaging sequence using gating times defined as occurrence times of gating events detected by the physiological monitor modified by the gating time offset.
