Abstract:
1. A magnetic resonance imaging apparatus comprising: a gradient magnetic field generator that generates a gradient magnetic field; an arithmetic processing unit that calculates a rephasing gradient magnetic field based on a gradient moment nulling (GMN) method; a measurement control unit that controls measurement of echo signals from an object by applying the rephasing gradient magnetic field to the object; and an input/output unit that displays a value of an imaging parameter and also receives inputting and setting of the imaging parameter value, wherein the arithmetic processing unit calculates a rephasing gradient magnetic field of a smaller amount of application than a rephasing gradient magnetic field of a predetermined order according to the imaging parameter value set as input, and the measurement control unit measures at least some echo signals using the rephasing gradient magnetic field of the smaller amount of application than the rephasing gradient magnetic field of the predetermined order.
