<p><P>PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus more easily and accurately setting the delay time for collecting data from a trigger such as an R-wave in the MRA (magnetic resonance angiography) synchronized with synchronous signals such as ECG (electro-cardiogram) signals. <P>SOLUTION: The magnetic resonance imaging apparatus includes: a pre-scanning means performing the pre-scan by changing the delay time from the trigger set on a signal representing the pulsation to the time to start data collection; a delay time calculating means for detecting a stable period from magnetic resonance signals or magnetic resonance image data in every delay time collected from a subject through the pre-scan, and calculating the delay time according to the detected stable period; and an imaging scanning means for generating blood-flow image data by performing the imaging scan with the delay time determined based on the calculated delay time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
