摘要：

This paper reports on the development and testing of a novel, whole cortex, 64 channel SQUID biomagnetometer system operating in an unshielded environment. The essential features of this new instrument are described including the cryogenics system, the room temperature digital electronics and signal processing capabilities. A noise cancellation scheme is incorporated which allows extraction of biomagnetic signals over the surface of the cortex while operating in the presence of large background magnetic interference. A system description and the results of preliminary magneto-encephalographic (MEG) measurements are presented.
