Low-field magnetic resonance imaging with a high-Tc dc superconducting quantum interference device
نویسندگان
چکیده
A spectrometer incorporating a high transition temperature dc superconducting quantum interference device ~SQUID! is used to obtain nuclear magnetic resonance signals from protons in mineral oil at room temperature in fields up to 3 mT. The spatial separation between the SQUID magnetometer at 77 K and the sample at room temperature is less than 1 mm. At 2 mT, the signal is easily resolved in a single scan. Two-dimensional images of samples consisting of pieces of lucite or glass immersed in mineral oil are obtained at 2 mT. © 1999 American Institute of Physics. @S0003-6951~99!03649-9#

Magnetic resonance spectrometer with a de SQUID detector
We describe a dc superconducting quantum interference device (SQUID) based magnetic resonance spectrometer particularly suited to measurements in the frequency range of 100 kHz to several megahertz. Results are presented for nuclear quadrupole resonance (NQR) of boron-II in boron nitride at 4.2 K, yielding {uQ = 1467 ± 2 kHz. We also present a direct measurement of the methyl group tunneling fr...
متن کاملInfluence of magnetoplasmonic γ-Fe2O3/Au core/shell nanoparticles on low-field nuclear magnetic resonance
Magnetoplasmonic nanoparticles, composed of a plasmonic layer and a magnetic core, have been widely shown as promising contrast agents for magnetic resonance imaging (MRI) applications. However, their application in low-field nuclear magnetic resonance (LFNMR) research remains scarce. Here we synthesised γ-Fe2O3/Au core/shell (γ-Fe2O3@Au) nanoparticles and subsequently used them in a homemade, ...
متن کاملNMR and MRI at ultra - low magnetic fields ( Title )
Laser polarized Xe and a high-Tc Superconducting QUantum Interference Device (SQUID) are used to obtain magnetic resonance images in porous materials at a magnetic field of 2.3 mT, corresponding to a Larmor frequency of 27 kHz. Image resolution of 1 mm is obtained with gradients of only 1 mT/m. The resolution of xenon chemical shifts in different physicochemical environments at ultra-low fields...
متن کاملMicrotesla MRI with a superconducting quantum interference device.
MRI scanners enable fast, noninvasive, and high-resolution imaging of organs and soft tissue. The images are reconstructed from NMR signals generated by nuclear spins that precess in a static magnetic field B0 in the presence of magnetic field gradients. Most clinical MRI scanners operate at a magnetic field B0 = 1.5 T, corresponding to a proton resonance frequency of 64 MHz. Because these syst...
متن کاملNovel excitation coils for non-destructive evaluation of non-magnetic metallic structures by high-Tc dc SQUID
A non-destructive evaluation (NDE) system was set up in our laboratory. A high-Tc dc superconducting quantum interference device (dc SQUID) made from YBa2Cu3O7−δ thin film on a 24◦ bicrystal SrTiO3 substrate was adopted as the magnetic flux sensor. Novel excitation coils and a balance circuitry were proposed and employed for evaluation of multilayer aluminium structure with artificial slits in ...
