Enhancing the Digital Image
2–18 Getting Started
Using the Sharpness Filter
Sharpness Filter
Use the Sharpness filter to emphasize a radiological
feature that could go unnoticed in the pure image and
spot the subtleties of the image. The filter emphasizes
lateral ducts or small fissures, exaggerates details
that are already clearly visible on the image, such as
amalgams or any other high-density material. Always
compare the filtered image to the pure image.
To confirm the interpretation, remove the
Sharpness
filter and use a contrast tool such as the
Highlight tool.
Using the Highlight Tool
Highlight Tool
The Highlight tool reinforces contrasts locally in an area
of the image. This tool is useful for investigating
interproximal areas and detecting caries and fractures.
You can apply the tool on a reduced image as well as
on a real-size image 100% (1:1) or at 200% (2:1).
To use the
Highlight tool, click the Highlight button,
and click and hold the mouse button to activate the tool
on the area of the image you want to investigate.
To adjust the diameter of the contrast enhancement
circle, use the slider displayed above the
Control
Panel window. Move the slider left to decrease the size
or right to increase the size.
Note
The data from the
Highlight tool is
exempt of artifacts
and there is no
counter-indication to
its use.
