Using the Window/Level Tool
The Adjust Contrast tool also lets you adjust contrast and brightness by clicking and dragging the mouse. In medical applications, this type of interactivity is often called adjusting the window/level.
When you start the Adjust Contrast tool and move the cursor over the image displayed in the Image Tool, the cursor changes shape to the Window/Level cursor . The following table summarizes the mouse motion.
|Horizontally to the left
||Shrinks the window from both sides
|Horizontally to the right
||Expands the window from both sides
||Moves the window to the right over the histogram, increasing brightness.
||Moves the window to the left over the image histogram, decreasing brightness.
The following example shows how to use the window/level capability to improve the contrast of an image.
