发明名称 Magnetic resonance imaging apparatus
摘要 The present invention provides an MRI apparatus which prevents from developing body move artifacts on the image to improve the image quality. In the navigator sequence a scan unit emits first RF pulse so as to excite first slice plane area which is out of the imaging area and is intersecting the navigator area including the epiglottis, then it emits second RF pulse so as to excite second slice plane area which is out of the imaging area and is intersecting the first slice plane area in the navigator area including the epiglottis. Thereafter a body move detector detects the displacement of epiglottis due to the deglutition movement based on the navigator echo data, a raw data selector unit selects as raw data the imaging data thus obtained in the imaging sequence based on the displacement of epiglottis, then the image of the slice plane including the esophagus in the subject is generated from the imaging data thus selected.
