Sentence examples for more powerful gradient from inspiring English sources

The hardware solution that reduces MRI data acquisition time by using more powerful gradient amplifiers is limited by technical and biological considerations like nerve stimulation.

With identical pulse sequences, a shorter TE can only be achieved if more powerful gradient systems are used, but current 3 T MR systems often utilise the same gradient units as high-end 1.5 T systems (Fig. 1).

With the advent of MRI systems with magnets as large as 7 T and more powerful gradient coils, both in small animal and clinical use, we anticipate an improvement in signal/contrast for the same MSN formulation.

By adopting a multi-layer design in which the coil wires are allowed to spread out into multiple layers wound at increasing radii, a more favourable scaling of resistance with efficiency is achieved, thus allowing the design of more powerful gradient coils with acceptable resistance values.

The improved performance of endorectal MRI is probably due to the maturation of MRI technology, including improvements in MRI technique (e.g. faster imaging sequences, more powerful gradient coils, and post-processing image correction), a better understanding of morphologic criteria used to diagnose extra-prostatic disease, and increased reader experience.

This makes superconducting circuits especially well-suited for combining a coarse search using simplex methods, which may then be refined with a more powerful gradient-based method.

The applications of diffusion MR imaging of the chest have increased considerably in the last few years due to recent technologic improvements, such as more powerful gradients and phased-array coils and the development of fast imaging techniques, such as echo planar imaging (EPI) and parallel imaging.

The ecological Carstairs indicator is more powerful, confirming a socioeconomic gradient for cancer of the lung, breast and bladder.

A potentially more powerful analysis to examine latitudinal gradients would be based on standardized sampling protocols to avoid any biases introduced by varying collection methods.

In the present study, ANN was trained by Levenberg Marquardt technique, since this technique is more powerful and faster than the conventional gradient descent technique (Aleksander and Morton 1995; Sivanandam and Deepa 2006).

Furthermore, the dose-response gradient can be confounded, e.g. by severity of the disease which may be a more powerful effect modifier than the dose-response pattern (23).
