摘要：
A magnetic resonance imaging apparatus of the invention comprises a static magnetic field generation unit which generates a static magnetic field in a gantry, a gradient magnetic field generation unit which applies a gradient magnetic field to a object in the static magnetic field, a radio frequency coil which receives a magnetic resonance signal from the object to which the gradient magnetic field is applied, a contour detection unit which detects a contour of the object, a coil movement unit which moves the radio frequency coil on the basis of the detected contour while the radio frequency coil is placed near and far relative to the object, and an image generation unit which generates a magnetic resonance image on the basis of the received magnetic resonance signal.
