This paper is a summary discourse on the real time navigator approach to suppressing motion effects in coronary magnetic resonance angiography. The concept of navigator approach, characteristics of coronary motion, design of navigator echoes for motion measurements, and navigator algorithms for motion effects suppression are reviewed and discussed. At the conclusion, an efficient and effective ...
