The high-Tc SQUID magnetometers also incorporate 16 mm multilayer superconducting flux transformers on the MgO substrates and demonstrate a magnetic field resolution of ~ 4 fT/√Hz at 77 K. Results are illustrated for the detection of auditory evoked magnetic responses of the human cortex and compared between high-Tc SQUIDs and a commercial low-Tc MEG system. Our results demonstrate that MEG systems can be upgraded using high-Tc SQUIDs to make them independent of helium and more user-friendly, saving operating costs and leading to the widespread utilization of MEG systems in clinical practice and at universities.}, month = {Oct}, date = {2012-10-07}, organization = {The Applied Superconductivity Conference, Portland (Oregon), 7 Oct 2012 - 12 Oct 2012}, cin = {ZEA-2 / INM-4 / PGI-5}, ddc = {530}, cid = {I:(DE-Juel1)ZEA-2-20090406 / I:(DE-Juel1)INM-4-20090406 / I:(DE-Juel1)PGI-5-20110106}, pnm = {423 - Sensorics and bioinspired systems (POF2-423)}, pid = {G:(DE-HGF)POF2-423}, typ = {PUB:(DE-HGF)8}, url = {https://juser.fz-juelich.de/record/127851}, }
