Abstract
A magnetic resonance imaging apparatus includes a data acquisition unit and an image data generating unit. The data acquisition unit acquires data according to a sequence derived by adding a coherent control pulse on a Steady-State Free Precession pulse sequence for repeating plural radio frequency excitations with a constant interval. The coherent control pulse has a center at a substantially center time between adjacent radio frequency excitations and a zero-order moment of which amount is zero. The image data generating unit generates image data based on the data.
