Table A7-10 Image Processing parameters
Parameter Definition
Contrast
Adjust
Adjusts image contrast. Also known as window width.
• Move the slider right for more contrast (towards pure black and white).
• Move the slider left for less contrast (towards uniform gray).
Range: 25% – 400% with increment of 1%
Brightness
Adjust
Adjusts image brightness from 25-210%. Also known as window level.
• Move the slider right for a lighter image.
• Move the slider left for a darker image.
NOTE: Brightness Adjust and Contrast Adjust should not be used for per-image
tuning/correction of brightness and contrast. They are used to modify the
default look of images from a particular exam. For example, if images from a
particular type of exam are appearing consistently lighter than they should
be, the Brightness Adjust slider can be moved left to adjust. However, for small
alterations of brightness on a particular image, use the Brightness and
Contrast controls in the Image Viewer screen.
Tissue
Contrast
Controls the general contrast between the thick and thin anatomy.
• Move the slider right to decrease bone/soft-tissue contrast.
• Move the slider left to increase bone/soft-tissue contrast.
Range: –0.15 to 0.15 with 0.01 increments.
NOTE: Unlike Tissue Equalization, which controls contrast within under-penetrated
(thick) or over-penetrated (thin) areas, Tissue Contrast controls the general
contrast between the thick and thin anatomy. For example, Tissue Contrast
can be used in combination with Tissue Equalization to define a Chest PA look
that is equalized in the lung fields, but with light spine/ribs.
Edge The amount of detail visible in bone structures. Increased edge equals increased
detail.
• Move the slider right to make images sharper.
• Move the slider left to make images smoother.
Range: 1 to 10 (discrete setting) with increments of 1
