Abstract:
1. A magnetic resonance imaging apparatus comprising: 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 an object in the static magnetic field; radio frequency coil which receives an MRI magnetic resonance signal from the object to which the gradient magnetic field is applied; a controller which detects a contour of the object; a coil movement unit which moves the radio frequency coil transversely towards or away from the object on the basis of the detected contour to maintain a predetermined separation limit between the coil and the object while the radio frequency coil is positioned longitudinally relative to the object to receive MRI signals; and an image generation unit which generates a magnetic resonance image on the basis of the received magnetic resonance signal.
