A Concept of LNA with Low Input Impedance Using Common Base BJT for Low-Field MRI
Aleksei A. Nasonov, Mikhail V. Murzin, Nikolay V. Anisimov +4
Purpose: In magnetic resonance imaging (MRI), preamplifier decoupling is used to improve the signal-to-noise ratio of a multichannel receive coil array. In low-field and ultra-low-…
Dual-Tuned 31P-1H Dual-Row Loop/Dipole 32-element Transceiver Array for Human Brain Spectroscopy at 9.4T
G. A. Solomakha, R. Pohmann, F. Glang +8
Purpose The goal of this work is to develop and evaluate a single-layer tight-fit 32-element double-tuned loop/dipole transceiver (TxRx) array for human brain 31P MRS at 9.4T, achi…
Overcoming the limitations of NMR Field Probes: A Novel Integrated Sensor Utilizing Pre-Polarization for (Ultra) Low Field MRI
Pavel Povolni, Dominique Goerner, Praveen Iyyappan Valsala +9
Access to magnetic resonance imaging (MRI) remains severely limited in low- and middle-income countries, especially in sub-Saharan Africa, despite rising rates of non-communicable…
Coaxial Dipole Array with Switching Transmit Sensitivities for ultrahigh field MRI
Dario Bosch, Georgiy A. Solomakha, Felix Glang +3
Purpose: To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra-high field MRI Methods: An array of eight…
High-resolution deuterium metabolic imaging of the human brain at 9.4 T using bSSFP spectral-spatial acquisitions
Praveen Iyyappan Valsala, Rolf Pohmann, Rahel Heule +6
We demonstrated the feasibility of using bSSFP acquisitions for off-resonance insensitive high-resolution [6,6'-2H2]-glucose deuterium metabolic imaging (DMI) studies in the health…
A wireless bilateral transceiver coil based on volume decoupled resonators for a clinical MR mammography
Pavel M. Tikhonov, Alexander D. Fedotov, Georgiy A. Solomakha +1
Wireless radio frequency coils provide a promising solution for clinical MR applications due to several benefits, such as cable-free connection and compatibility with MR platforms…
