Methods and Instrumentation for Biomagnetism.

Abstract

Capabilities for biomagnetic measurements have been advanced by the successful development of a Superconducting Quantum Interference Device(SQUID)-based magnetic sensor that does not rely on liquid helium for cooling. This system, known as CryoSQUID, achieves a sensor noise level that is appropriate for high-sensitivity measurements of the magnetic field of the human brain. It employs an external compressor and a two-stage refrigerator within the sensor's dewar to cool a dc-SQUID and associated detection coil. The sensor can be operated in any orientation, including horizontally and up-side down. Keywords: Magnetoencephalograms; Cardiography.
