Sentence examples for ratio of attenuation from inspiring English sources

The following measures were directly made or calculated by the PIXImus2 software: bone mineral density, bone mineral content, bone area, tissue area, R soft tissue value (RST – ratio of attenuation of low energy and high energy beams in soft tissue), percent fat, and total tissue mass (TTM).

CCO was calculated as the ratio of mean attenuation in the coronary ROI over the aorta ROI.

Corrected contrast opacification (CCO) is calculated as the ratio of mean attenuation in the coronary ROI over the ROI in the descending aorta (large white circles).

The observed ratio of the attenuation of a P wave to that of an S wave for frequencies higher than 1 Hz mostly ranges between 0.7 and 2 in the lithosphere as shown in figure 5.3 of Sato and Fehler (1998).

The ratio of energy attenuation in the luminescent panel separates bone, lean tissue, and fat mass.

The PEW and RPEW are the percentage enhanced wash-out ratio of enhanced attenuation according to the timing of the early and delayed imaging.

Because direct hydrogen exchange of the backbone amide protons with solvent cannot be fully eliminated by lowering the sample pH to 6.0 and lowering the temperature to 5 °C, we monitor the ratio of the attenuation factors caused by water saturation in aS samples without CR and equivalent samples containing CR in a 1 1 or 4 1 stoichiometry.

In summary we have presented the Relative Contrast Gain as a simple and practical tool to determine the relative contrast-to-noise-ratio of the attenuation- and differential phase-contrast signals that are available from grating-based X-ray imaging.

While relationships of Fat or Lean with the percentage traits FatPC and LeanPC, as well as with Weight are obvious, there is also a linear relationship between FatPC and ratio of the mass attenuation coefficients of soft tissue (R value = X-ray attenuation coefficient) [ 32- 34].

A detailed parametric study of the bubble behavior was executed using the ratio of scattering to attenuation (STAR).

Also, a new parameter (composition factor k) given by the ratio of the linear attenuation coefficients from the two tomograms is introduced.
