| Research Abstract |
A new type of the magnetic shielding system aiming for the MCG measurement has been developed in a real-scale. Magnetic shells are separated to accommodate SQUID sensor system partially into the shield through the spacing and to make loading of a patient to the inside of the shield easy. A new active compensation method has been developed to restore a high shielding performance to the separate shell structure. Magnetic field from a human heart has been measured with this magnetic shield.
