Abstract:
A magnetic resonance imaging apparatus comprising: a magnet configured to form a static magnetic field in an imaging area; a cylindrical structure having a guide; a radio frequency coil configured to receive a nuclear magnetic resonance signal generated by transmitting a radio frequency signal into a object set in the static magnetic field; and a radio frequency coil drive structure configured to adjust a distance between the radio frequency coil and a body surface of the object by using a moving structure configured to move along with the guide, a wire configured to move the moving structure and a motor connected to the wire.
