Abstract:
A nuclear magnetic resonance diagnosis apparatus comprising:a measurement system including a magnet for generating a static magnetic field in a space in which an object to be inspected is placed, a gradient magnetic field coil for generating a gradient magnetic field in the space, an irradiation coil for applying a radio frequency magnetic field to the object to be inspected and a receiving coil for detecting a nuclear magnetic resonance signal generated from the object to be inspected; a gradient magnetic field power supply for driving the gradient magnetic field coil; a signal processing system for reconstructing a sectional image of the object to be inspected based on the nuclear magnetic resonance signal; an electromagnetic shield room having an electrically conductive shield in which the measurement system is arranged; a line noise filter for the gradient magnetic field connected between the gradient magnetic field coil and the gradient magnetic power supply; and a cabinet in which the gradient magnetic field power supply and the line noise filter are contained, the cabinet being mechanically and electrically connected to the electrically conductive shield of the shield room.
