Cardiac gating 1 in nuclear magnetic resonance imaging

Abstract

In order to obtain NMR images of the heart, and to measure blood flow by NMR, the signal acquisition must be synchronized wilh the patient's cardiac cycle. Some of the problems of detecting the cardiac cycle within a strong unqorm magnetic field without introducing R F interference into the imaging system are discussed. some general applications of cardiac gated NMR imaging are presented.
