More Information
Summary:The present invention allows a subject to hold breathing at any position, and it is confirmed whether or not the breath holding is really performed in the middle of imaging to reflect its result to the imaging sequence. An image 411 showing a temporal change of respiratory displacement of the subject is generated from nuclear magnetic resonance signals acquired by executing the navigator sequence 231 repeatedly on the subject. Upon accepting from an operator a confirming operation that the operator viewing the image confirms a state of breath holding, the navigator sequence 231 is switched to the real imaging sequence 211 and the real imaging sequence is executed for a predetermined period of time. Those operations are repeated more than once. It is also possible to determine whether or not the breath holding during the imaging sequence is successfully performed, based on a difference in respiratory displacement between immediately before and immediately after the real imaging sequence.
