A family of new on-resonance saturation pulses for magnetization transfer in MRI is proposed. These pulses can be represented as a product of a shaped function and a cosine function. The shaped function can have many different forms, one of which is a Gaussian function. The experimental ...
A method of performing magnetization transfer contrast (MTC) using a pulse sequence based on a series of onresonance binomial pulses preceding a convention... MD Hollett,AM Aisen,NY Hong,... - 《Magnetic Resonance Imaging》 被引量: 34发表: 1994年 Optimum setting of binomial pulses for magnet...
A general method is described for the accumulation of nuclear magnetic resonance proton spectra in water and other proton-containing solvents, which minimizes the spectral distortions usually associated with the intense solvent resonance. The technique involves the addition of a relaxation agent, which di...
Many studies have since chosen a similar repetition frequency in USN pulses presumably based on this work, but there is little physiological basis for introducing this pulsed scheme26,28,29. King et al. did not find PRF to increase stimulation success, while others have noted that burst ...
In two human experiments conducted outside the magnetic resonance imaging (MRI) environment18, post-extinction L-DOPA reduced CRs at test only in participants who showed successful extinction learning; in one other non-MRI study, the L-DOPA effect was not significant19. Hence, L-DOPA is a ...
Toward quantum information processing by nuclear magnetic resonance: Pseudopure states and logical operations using selective pulses on an oriented spin 3/2 nucleus 来自 掌桥科研 喜欢 0 阅读量: 37 作者:N Sinha,TS Mahesh,KV Ramanathan,A Kumar ...
We create high-energy pulses by providing large amounts of excessive negative dispersion, which increases the pulse width while keeping the nonlinearity of the cavity constant. With a chirped fiber grating of 3.4-ps(2) dispersion, 3-ps pulses with an energy content higher than 1 nJ are ...

Hyperfine-mediated gate-driven electron spin resonance An all-electrical spin resonance effect in a GaAs few-electron double quantum dot is investigated experimentally and theoretically. The magnetic field dependence and absence of associated Rabi oscillations are consistent with a novel hyp... E Laird...
Alternatively, we can directly connect the resonator of the signal source to the qubit and tune them on resonance when performing the qubit gate operation. With a similar coupling strength and photon numbers, the estimated Rabi rate is about 30MHz, which is much faster than that of the ...
