چکیده
Fig. 2 Results for three HS pulses: a high bandwidth pulse (row 1), a reduced bandwidth pulse (row 2), and an optimized pulse with reduced bandwidth (row 3). Flip-angle maps are calculated on the grid of targeted static and RF field variations (column 1) and within an axial slice of the human brain (column 2). Frequency profiles for B1/ B1,nom intensities of 0.35, 0.50, 0.75, and 1.00 are shown in column 3 with AM and FM waveforms in column 4.

Hyperbolic secants yield Gabor frames
We show that (g2, a, b) is a Gabor frame when a > 0, b > 0, ab < 1 and g2(t) = ( 1 2πγ) 1 2 (cosh πγt)−1 is a hyperbolic secant with scaling parameter γ > 0. This is accomplished by expressing the Zak transform of g2 in terms of the Zak transform of the Gaussian g1(t) = (2γ) 1 4 exp(−πγt2), together with an appropriate use of the Ron-Shen criterion for being a Gabor frame. As a side result it f...
متن کاملReducing Contamination in PASL using BASSI RF pulses
Introduction Arterial spin labeling is sensitive to contamination due to off-resonance effects of the RF label. While it has been argued that in PASL these effects are small compared to pulse profile effects [1], this assessment has to be re-evaluated in view of the advent of highly selective gradient-modulated adiabatic pulses such as FOCI [2], requiring several times more RF energy than the c...
متن کاملAdiabatic inversion pulses for myocardial T1 mapping.
PURPOSE To evaluate the error in T1 estimates using inversion-recovery-based T1 mapping due to imperfect inversion and to perform a systematic study of adiabatic inversion pulse designs in order to maximize inversion efficiency for values of transverse relaxation (T2) in the myocardium subject to a peak power constraint. METHODS The inversion factor for hyperbolic secant and tangent/hyperboli...
متن کاملTwo Settings of the Dai-Liao Parameter Based on Modified Secant Equations
Following the setting of the Dai-Liao (DL) parameter in conjugate gradient (CG) methods, we introduce two new parameters based on the modified secant equation proposed by Li et al. (Comput. Optim. Appl. 202:523-539, 2007) with two approaches, which use an extended new conjugacy condition. The first is based on a modified descent three-term search direction, as the descent Hest...
متن کاملJoint inversion of ReMi dispersion curves and refraction travel times using particle swarm optimization algorithm
Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...
