Enhancing the Digital Image

Using the Relief Filter
Relief Filter
The Relief filter interprets the gray shades in bulk. Use
the filter to distinguish and compare between similar
shades of gray.
For example, use this filter to distinguish the extremity
of an endodontic file placed in a canal that is confused
with Gutta Percha or cement.
To tweak the
Relief filter, manually adjust brightness
and contrast.
Using the Measurement Tool
Measurement Tool
Use the Measurement tool to calculate the distance
between points on an image. Measurements taken
on x-ray images always contain a certain degree of
uncertainty due to the properties of the radiological
examination itself. The projection phenomenon
renders a three-dimensional reality into a reduced
two-dimensional image. The curves positioned in the
axis of the x-ray beam are thus translated into straight
lines on the image.
Make sure the sensor positioning technique respects
the rule of parallel planes and that the targeted subject
does not contain any curves in the axis of the x-ray
beam. Depending on the distance object to sensor or
focal point to object, calibrate the tool to compensate
for the conic enlargement of the projection. Refer to
the Kodak dental imaging software online Help.
Caution!
The information
provided by the
filters is only
indicative. Confirm
diagnosis on a
non-filtered image.
Caution!
Take the
measurements in the
software with the
tools provided in
the Kodak dental
imaging software.
Do not take
measurements on a
printed image.
