Abstract:
1. A magnetic resonance imaging apparatus including: measurement control means for dividing a k space into a high repetitive-frequency measurement area containing an origin of the k space and measured at a high repetitive-frequency and a plurality of low repetitive-frequency measurement areas not containing the origin and measured at a low repetitive-frequency, and obtaining k space data by repeating measurement of said high repetitive-frequency measurement area and measurement of at least one of said low repetitive-frequency measurement areas between said measurements of the high repetitive-frequency measurement area in a predetermined measurement order; signal processing means for reconstructing an image by using all or a portion of the k space data as an image reconstruction set; and display means for displaying the resulting image; wherein said signal processing means acquires a time phase evaluation value from said high repetitive-frequency measurement area, determines a time phase at which said time phase evaluation value reaches a predetermined threshold value or greater, and said measurement control means rearranges the predetermined measurement order of some of said high repetitive-frequency measurement area and said at least one of said low repetitive-frequency measurement areas in such a manner that a measurement period of said high repetitive-frequency measurement area contains said time phase.
