Sentence examples for selective pulse from inspiring English sources

A cardiac gated one-dimensional chemical shift imaging sequence was used, and to eliminate contamination from liver, a 7 cm slice was selected in the foot head direction using a selective pulse (of the 'spredrex' type, as outlined in [ 22]).

Thus, the sensitivity of a ZS experiment is directly proportional to the bandwidth of the selective pulse, and inversely proportional to the strength of the slice-selection gradient.

The Oneshot segment of the pulse sequence used the same parameters as for Figure 2 c; the Zangger Sterk segment used a 37 ms (50 Hz) rsnob[ 36] selective pulse under a 0.23 G cm−1 gradient, with coherence transfer pathway selection pulses of width 1.5 ms with amplitude G1=31.31 G cm−1.

The result is a Globally Antisymmetric Selective Pulse, or GASP.

Increasingly, the development of specific contrast agents and selective pulse sequences allows more detailed analysis of tissue properties such as diffusion, flow, and changes in vascular oxygenation.

By decomposing the point-to-point pulses into two sub-pulses, it is shown that an inverse scattering algorithm for selective pulse design can be used to calculate selective rotation pulses with any desired spinor response, subject to the constraint that the second spinor component have constant phase across the slice.

Applications include increased bandwidth for a given pulse length compared to equivalent pulses requiring no phase correction, selective pulses, and pulses that mitigate the effects of relaxation.

The non-selective pulses are subsequently transformed into spatially selective pulses with the same field-insensitive properties through modification of the spectral composition of the individual sub-pulses which are then executed in conjunction with an oscillating gradient waveform.

The design of slice selective pulses for magnetic resonance imaging can be cast as an optimal control problem.

29Si NMR spectra of reaction mixtures of TEOS and DMDEOS were effectively measured by a slightly modified DEPT experiment, in which the pulse sequence is divided into two parts and all pulses on protons are replaced by selective pulses.

The goal of this article is to demonstrate the efficacy of optimal control methods to provide broader bandwidth frequency selective pulses for in vivo spectroscopy in the presence of limited RF power.
