Summary

DESCRIPTION OF AND THE FIRST RESULTS OBTAINED WITH A 30 CHANNEL SYSTEM FOR BIOMAGNETIC DIAGNOSIS OF THE HUMANBODY. THE SYSTEM CONSISTS OF A LIQUID HELIUM COOLED SENSOR ARRAY, ENCLOSED IN A FIBREGLASS CRYOSTAT, LOCATED IN A MAGNETICALLY SHIELDED ROOM WITH A MODERATE SHIELDING FACTOR, SUSPENDED BY A MANIPULATOR ALLOWING THE POSITIONING OF THE SENSOR ARRAY RELATIVE TO THE BIOMAGNETIC SOURCE. THE SQUIDS ARE OPERATED IN THE FLUX LOCKED LOOP MODE. THERE IS NOW A PRACTICAL TOOL FOR RESEARCH AND FUNCTIONAL DIAGNOSIS OF THE BRAIN AND THE HEART.
