Chemical shift imaging (CSI) by precise object displacement.
A mechanical device (NMR lift) has been built to displace vertically an object (typically an NMR sample tube) inside the NMR probe with an accuracy of 1 microm. A series of single pulse experiments are performed for incremented vertical positions of the sample. With a sufficiently spatially selective radio-frequency (r.f.) field, one obtains chemical shift information along the displacement dir...
متن کاملNatural linewidth chemical shift imaging (NL-CSI).
The discrete Fourier transform (FT) is a conventional method for spatial reconstruction of chemical shifting imaging (CSI) data. Due to point spread function (PSF) effects, FT reconstruction leads to intervoxel signal leakage (Gibbs ringing). Spectral localization by imaging (SLIM) reconstruction was previously proposed to overcome this intervoxel signal contamination. However, the existence of...

X. Zhu, H. Qiao, X. Zhang, H. Lei, W. Chen Center for Magnetic Resonance Research, University of Minnesota, Minneapolis, Minnesota, United States SYNOPSIS In vivo 3D P chemical shift imaging (CSI) was performed on entire human brain using a H/P double-tuned TEM volume coil at 7 Tesla. Excellent P NMR sensitivity was achieved with voxel size of 15.5 ml. The P CSI approach was incorporated with t...
متن کاملSNR Maximization at CSI Aware AF Relay
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

Summarn Recognition of psychological distress in patients with cancer. some of which can be ameliorated With appropriate intervention. is a crucial aspect of patient care. Previous studies, with the exception of one. indicate that oncologists often fail to detect general distress and do not identify those patients with significant psychological disorder. As approximately 25-30% of patients expe...
