MRIMRI USING NAVIGATORS WITH QUALITY EVALUATION OF NAVIGATOR SIGNAL

摘要

A magnetic resonance apparatus for acquiring a navigator signal for detecting a position of each edge of the first body movement region from a navigator region including a first body movement region and a second body movement region, A profile generating unit that generates a profile indicating a relationship between each position in the navigator area and a signal intensity based on the navigator signal; Determining a first region of the profile that is closer to the position of the edge from the region corresponding to the first body motion region of the profile and determining a first region of the profile corresponding to the second body motion region of the profile; The side closer to the position of the edge Based on a first characteristic value indicating a characteristic of a signal intensity in the first region and a second characteristic value indicating a characteristic of a signal intensity in the second region, the quality of the navigator signal Of the magnetic resonance imaging apparatus is evaluated.;
