Description: This book presents the first in–depth reference to discuss Susceptibility Weighted Imaging for students and professionals Within the pages of this book, the reader will find comprehensive coverage of the major concepts that underlie the origins of susceptibility weighted imaging (SWI) in magnetic resonance imaging (MRI) and its wide range of… (More)
PURPOSE To reduce the off-resonance artifact in susceptibility-weighted imaging (SWI)-based MR venography (MRV) in the brain regions with severe field inhomogeneity and to reduce the signal loss in the minimum-intensity projection (mIP) display of the 3D MRV. MATERIALS AND METHODS A novel postprocessing approach was presented to map the local field… (More)
In this paper we investigate the step-type contrast structure of a second-order semilinear differential equation with integral boundary conditions. The asymptotic solution is constructed by the boundary function method, and the uniform validity of the formal solution is proved by the theory of differential equalities.
GOAL Random phase-encode undersampling of Cartesian k-space trajectories is widely implemented in compressed sensing (CS) MRI. However, its one-dimensional (1-D) randomness inherently introduces large coherent aliasing artefacts along the undersampled direction in the reconstruction and, thus, degrades the image quality. This paper proposes a novel… (More)
Tencent Weibo, the Chinese Twitter-like service gains its popularity in recent years. Enormous commercial potential lies in the user behavior on the social media such as Tencent Weibo. In this project, different machine learning algorithms were applied to predict user following behavior on Tencent Weibo. The accuracy of prediction, true positive rate and… (More)
Conventional susceptibility-weighted imaging (SWI) uses both phase and magnitude data for the enhancement of venous vasculature and, thus, is subject to signal loss in regions with severe field inhomogeneity and in the peripheral regions of the brain in the minimum-intensity projection. The purpose of this study is to enhance the visibility of the venous… (More)
