Journal ArticleDOI
Microtesla MRI with a superconducting quantum interference device.
Robert McDermott,Seung-Kyun Lee,Bennie ten Haken,Andreas Trabesinger,Alexander Pines,John Clarke +5 more
TL;DR: It is shown that prepolarization of the nuclear spins and detection with a superconducting quantum interference device (SQUID) yield a signal that is independent of B0, allowing acquisition of high-resolution MRIs in microtesla fields.
Journal ArticleDOI
A low-noise ferrite magnetic shield
TL;DR: In this paper, the authors identify a 1∕f component of the magnetic noise due to magnetization fluctuations and derive general relationships for the Johnson current noise and magnetization noise in cylindrical ferromagnetic shields in terms of their conductivity and complex magnetic permeability.
Journal ArticleDOI
Subfemtotesla radio-frequency atomic magnetometer for detection of nuclear quadrupole resonance
TL;DR: In this article, a radio-frequency tunable atomic magnetometer was developed for detection of nuclear quadrupole resonance (NQR) from room temperature solids, which has a field sensitivity 0.24fT∕Hz1∕2 at the 423kHz N14 NQR frequency of ammonium nitrate.
Journal ArticleDOI
SQUID-detected MRI at 132 microT with T1-weighted contrast established at 10 microT--300 mT.
Seung-Kyun Lee,Michael Mössle,Michael Mössle,Whittier Myers,Whittier Myers,Nathan Kelso,Nathan Kelso,Andreas Trabesinger,Andreas Trabesinger,Alexander Pines,Alexander Pines,John Clarke,John Clarke +12 more
TL;DR: T(1)-weighted contrast MRI with prepolarization was detected with a superconducting quantum interference device (SQUID) in this article, where a spin evolution period in a variable field between prepolarisation and detection enabled the measurement of T(1) in fields between 1.7 microT and 300 mT.
Journal ArticleDOI
Multi-channel atomic magnetometer for magnetoencephalography: a configuration study.
Kiwoong Kim,Samo Begus,H. Xia,Seung-Kyun Lee,Vojko Jazbinšek,Zvonko Trontelj,Michael Romalis +6 more
TL;DR: Two configurations of such a multi-channel atomic magnetometer optimized for MEG detection are studied and measurements of auditory evoked fields (AEF) from a human brain as well as localization of dipolar phantoms and auditory evoking fields are described.
