ABSTRACT:
A magnetic resonance imaging system includes a field generation section, an excitation section, an excitation control section, a resonance data acquisition section, and an image generation section. The field generation section generates a static magnetic field, a gradient magnetic field, and a selective excitation pulse. The excitation section controls the field generation section to apply the static field, the gradient field, and the pulse to an object, at a predetermined timing, to selectively excite a magnetic resonance phenomenon in a specific slice of the object. The excitation control section controls the excitation section to excite a plurality of slices. The excitation control section causes the excitation section to excite a certain slice of the object, and causes the excitation section to excite another slice, separated from the previous slice at least by a thickness of the slice determined by the selective excitation pulse, within an excitation-repeating time. The resonance data acquisition section detects a signal induced by the magnetic resonance, to acquire data relating to the resonance. The image generation section generates an image on the basis of the resonance data.
