Alternative winding patterns for twisted solenoid coils with improved characteristics for TRASE MRI
Nahid Ghomimolkar, Alexander E. Krosney, Christopher P. Bidinosti
Transmit Array Spatial Encoding (TRASE) is an MRI technique in which spatial encoding is achieved using phase gradients of the B1 field. This approach offers potential advantages s…
Generating accurate tip angles for NMR outside the rotating-wave approximation
Christopher P Bidinosti, Geneviève Tastevin, Pierre-Jean Nacher
The generation of accurate tip angles is critical for many applications of nuclear magnetic resonance. In low static field, with a linear rather than circular polarized rf field, t…
The Impact of Coupling on Estimation of Local and Global SAR with Transmit Arrays
Pei-Shan Wei, Christopher P. Bidinosti, Scott B. King
In pTx MRI systems, the prediction of local SAR is based on numerical electromagnetic (EM) simulations and used to scale RF power to ensure FDA SAR limits are not exceeded. This pr…
MRI of the lung using hyperpolarized He-3 at very low magnetic field (3 mT)
C. P. Bidinosti, J. Choukeife, G. Tastevin +2
Optical pumping of He-3 produces large (hyper) nuclear-spin polarizations independent of the magnetic resonance imaging (MRI) field strength. This allows lung MRI to be performed a…
In-Vivo NMR of Hyperpolarized Helium-3 in the Human Lung at Very Low Magnetic Fields
Christopher P. Bidinosti, Jamal Choukeife, Pierre-Jean Nacher +1
We present NMR measurements of the diffusion of hyperpolarized helium-3 in the human lung performed at fields much lower than those of conventional MRI scanners. The measurements w…
