Micro-Coils for MR Spectroscopy by Deep Silicon Etching
A process for batch fabrication of low-cost microcoils for magnetic resonance spectroscopy is demonstrated. Conductors are fabricated on oxidised silicon substrates by electroplating metals inside a deep photoresist mould, and passivated using an epoxy-based resist. Through-wafer deep reactive ion etching is used to define sample volumes and stencil cuts around each die, and dies are separated ...
متن کاملMR imaging of the intratemporal facial nerve by using surface coils.
MR images of the intratemporal portion of the facial nerve were obtained with surface coils using a 0.3-T permanent magnet whole-body imaging system. Various 2DFT spin-echo pulse sequences were used to produce 5-mm thick sections with 0.5-mm pixels on a 512 X 512 acquisition matrix. The MR images from normal volunteers were correlated with cryosection specimens of three fresh human cadavers. Th...
متن کاملDo carotid MR surface coils affect PET quantification in PET/MR imaging?
Translational and Molecular Imaging Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA To evaluate the effect of surface coils for carotid MR imaging on PET quantification in a clinical simultaneous whole-body PET/MR scanner. A cylindrical phantom was filled with a homogeneous 2L water-FDG mixture at a starting dose of 301.2MBq. Clinical PET/MR and PET/CT systems were used to...
متن کاملWhole Body Screening Using High-Temperature Superconducting MR Volume Coils:
Previous studies on HTS coils can be put into two categories: tape surface coils and thin-film surface coils[1-4]. In this study, we build a whole new Bi2Sr2Ca2Cu2O3 (Bi-2223) superconducting volume coil (length of 8 cm) designed for the mice whole body imaging at Bruker 3T MRI system. The HTS volume coil has 2.3 folds higher S/N than that of the HTS volume coil at 300K for the mice body screen...
متن کاملMR scanner independent 3D B1 eld mapping of magnetic resonance spectroscopy RF coils using an automated measurement system
Knowledge about the magnetic eld distribution in radio frequency coils is important for both magnetic resonance imaging and magnetic resonance spectroscopy. The information about the eld's distribution is used to obtain correct excitation pulse ip angles, as well as to perform signal strength corrections. Another use is also accelerating imaging and spectroscopic examinations, where accurate de...
