| 概要 | We developed a magnetoencephalogram system equipped with a superconducting magnetic shield and a zero boil-off system. A phantom signal-source estimation was performed as a verification test with the zero boil-off system in operation, and the accuracy was evaluated in terms of the magnetic field distribution and estimation error. The magnetic field distribution corresponding to the source current and the number of additive averages within 3 mm of the estimation error were obtained. The results demonstrate the practicality and effectiveness of this system. |
