NMR gated imaging apparatus

摘要

Disclosed is an NMR gated imaging apparatus in which an ultrasonic pulse signal is repeatedly transmitted toward the heart of a human body from an ultrasonic transducer to detect the position of the heart on the basis of the time of detection of a peak of an echo signal, and excitation and measurement of an NMR signal are executed only when a peak detector generates a detection output signal having a level included in a predetermined range. Thus, the NMR signal is repeatedly measured according to a programmable phase encoding amount at a limited phase of gated imaging.
