win·dow width

the range of CT numbers (in Hounsfield units) included in the gray scale video display of the CT image, ranging from 1 to 2000 or 3000, depending on the type of machine. Also, the range of electromagnetic energies passed by an electronic screening module of an imaging device, as by a scintillation camera.
See also: window level.

Abbreviation: WW
In digital imaging, the number of shades of gray in an image.

The integrated residual squares criterion (IRSC) method of Fan and Gijbels (1995) is used to obtain the window width, which is a pre-asymptotic, data-driven, residual-based approach.
Acute stroke: improved nonenhanced CT detection--benefits of soft-copy interpretation by using variable window width and center level settings.
The window width of the WMPDS-S/B algorithm in TN concentrations is 15 and in TC concentrations is 11.
(3) Main lobe was obtained by a window, where the window width was the same as the original probe pulses width, as shown in Figure 1(c); maximum likelihood algorithm was applied to find the starting point of the window.
One method to reduce this complexity is to set smaller parameter values for the number of variations, window width and height.
From Figures 29-56, the best kernel models for Bloemfontein are Rectangular for all the four seasons and the optimum window width, h, is 0.006 for all the four months.
We computed the correlation between window width and hit ratio for both the healthy control and patient group and then compared these correlation coefficients between them.
We introduced a "normalized window width" that is normalized on the basis of the averaged value of the center of the window.
But, STFT also has the limitation of fixed window width chosen apriority and this causes limitations for low-frequency and high-frequency non-stationary signals analysis at the same time, the location on the time series may be lost or incorrect [10].
The 2009 International Energy Conservation Code (IECC), for example, requires that general lighting in daylighted areas adjacent to windows--measuring window width plus 2 ft on each side, and 15-ft deep--must be controlled separately from other general lighting in the space, imposing an additional control zone and limiting its size to the size of the daylight zone.
Drapes are similar to screen shadings, except that the drapery fabric may be folded or pleated along the window width, hence forming open vertical pockets of air.
