Integro‐Differential Equations in Angular Stabilization of Drone's Motion by Distributed Feedback Control

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we propose angular stabilization of drone's motion using distributed feedback control in the form of an integral operator. It should be stressed that the memory of this integral operator could be unbounded. It is intuitively clear that large length of the observation time opens new possibilities to construct better control based

Fiber orientation‐dependent T1 angular features in human white matter at 1.5 T, 3 T, and 7 T

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose White matter (WM) microstructure influences T1 in vivo. Here, T1 angular features were studied in human WM in vivo in quantitative terms at 1.5 T, 3 T and 7 T. Methods MP2RAGE MRI was used to compute absolute T1 images of the brain at three fields.

Dynamic contrast enhanced‐magnetic resonance fingerprinting (DCE‐MRF): A new quantitative MRI method to reliably assess tumor vascular perfusion

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose The clinical utility of conventional DCE‐MRI methods is limited by the use of conventional qualitative dynamic T1‐weighted images, resulting in poor reproducibility. This study presents the initial implementation of a new DCE‐magnetic resonance fingerprinting (DCE‐MRF) methodology to provide reproducible, quantitative assessments of ...

Quantitative macromolecular proton fraction imaging using pulsed spin‐lock

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Recent studies have shown that spin‐lock MRI can simplify quantitative magnetization transfer (MT) by eliminating its dependency on water pool parameters, removing the need for a T1 map in macromolecular proton fraction (MPF) quantification. However, its application is often limited by the requirement for long radiofrequency (RF) pulse

Absolute quantification of cerebral metabolites using two‐dimensional proton MR spectroscopic imaging with quantitative MRI‐based water reference

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Metabolite concentrations are valuable biomarkers in brain tumors (BTs). However, absolute quantification of metabolites using MR spectroscopy requires a correction of water relaxation using time‐consuming quantitative MRI (qMRI) sequences in addition to a lengthy two‐dimensional spectroscopic water‐reference acquisition.
