Contrast scale definition

Contrast scale means the change in the linear attenuation coefficient per CTN relative to water, that is:
Contrast scale means the change in the linear attenuation coefficient per CTN relative to water, that is: where:µx = Linear attenuation coefficient of the material of interest.µw = Linear attenuation coefficient of water.CTNx = of the material of interest.CTNw = of water.
Contrast scale means the change in the linear attenuation coefficient per computed tomography number relative to water, that is:

Examples of Contrast scale in a sentence

  • Image quality report must record the actual results of the assessments, manufacturer specifications for comparison, and indicate Pass or Fail for the following parameters:Standard 1.4Ba. Contrast scale; b.

  • This definition assumes that the dose profile is centered around z = 0 and that, for a multiple tomogram system, the scan increment between adjacent scans is nT.b. "Contrast scale" means the change in the linear attenuation coefficient per CTN relative to water, that is: where: μx=Linear attenuation coefficient of the material of interest.μw=Linear attenuation coefficient of water.(CTN)x=CTN of the material of interest.(CTN)w=CTN of water.

  • Contrast scale" means the change in the linear attenuation coefficient per CTN relative to water, that is: CS = where:μx − μw(CTN ) x − (CTN ) w μx = Linear attenuation coefficient of the material of interest.μw = Linear attenuation coefficient of water.

  • Contrast scale values were not linearly related to either of the dimensions: Note that each tone-mapper plotting symbol sits on a ring of constant apparent contrast (the plot includes iso-contrast con- tours, the smallest contour in the center of the plot indicating the lowest level of apparent contrast ratings).

  • Ironically, as mentioned before, the Dutch parliament, operating in a country boasting the highest penetration level of broadband Internet access, had also found the need to put cable and landline access on equal regulatory footing, by forcing them both to unbundle their local loops.
