We have developed new systems for magnetoencephalography (MEG). The pick up coil is a coaxial type first-order gradiometer with 50-mm base line. The magnetic field resolution of the system is about 4 fT/Hz/sup 0.5/ or 0.8 (fT/cm)/Hz/sup 0.5/ in white noise region. The unique feature of the system is the gantry-free horizontal dewar, which is fabricated through what we call "ship-in-a-bottle approach". Less than 10-liter/day liquid helium consumption for the 100-liter capacity is realized. One… CONTINUE READING
