The introduction of faster gradients and a parallel acquisition technique has resulted in even greater spatial resolution and faster acquisition times.
Spin-echo images were employed as opposed to the faster gradient-echo, as spin-echo approaches are less prone to confounds from radiofrequency inhomogeneity in assessment of T1 changes than are gradient echoes.
Given the complexity of protein samples, columns with higher peak capacities are needed, especially for the faster gradients that are useful for multidimensional separations.
As for the optimization algorithm, we adopt a fast gradient method, i.e., GAPG [34], to estimate latent image, contributing to the faster convergence of the deblurring algorithm.
The acquisition protocols for dMRI are inherently complex, which require fast gradient switching in Echo-Planar Imaging (EPI) and longer scanning time.
Benefits of simultaneous programmed elution in two-dimensional liquid chromatography are shown, with emphasis on fast gradient elution in second dimension using various gradient types and profiles.
A fast gradient HPLC method (cycle time 15 min) has been developed to determine Human Serum Albumin HSAA) binding of discovery compounds using chemically bonded protein stationary phases.
They have shown that in the particular case γ(t)= 3t, this is a continuous version of the fast gradient method initiated by Nesterov, with Φ(x t))−minHΦ="O 1t2) as t→+∞ in the worst case.
The purpose of this study was to investigate the diagnostic utility of a PET/MRI with only an axial T1-weighted fast gradient echo sequence using a body coil (which is the basic sequence needed for MR-based attenuation correction [MRAC]) compared with standard low-dose PET/CT.
The potential of the fast gradient method for solving linear quadratic model predictive control (MPC) problems in the sub-millisecond range was only recently recognised by Richter et al. This paper aims to push the execution-time limit even further by exploiting the computational power offered by parallel computing architectures.
Whole-brain anatomical images were acquired at the end of each session using an axial 3D T1-weighted inversion-recovery fast gradient echo (or IR-prepped fast gradient echo) sequence.
