3.7.3.1
Measuring lengths
Explanation
The purpose of this function is to determine dimensions, distances or size
ratios of the objects in the X-ray image. It is also possible to measure curved
lines by setting interpolation points.
3.7.3.1.1
Validity
Explanation
This function can be used for X-ray and video images (but not for live and still
images).
Special case for TSA exposures with an
ORTHOPHOS XG Plus:
NOTICE
For safety reasons, a message prompting you to reconfirm the command
is displayed before the changes are undone.
CAUTION
Always use a reference object as a reference for length measurements,
intraoral exposures and ORTHOPHOS exposures! See Section
"Correcting the results of a length measurement [
NOTICE
The indicated lengths are relative values.
They depend on the dimensions of the sensors used for acquiring the
images.
This also applies to imported images.
NOTICE
Measurement results on imported images may, and on video exposures
will, only appear as pixel values if the imported data does not contain the
necessary information for the exact determination of the length.
This may be the case, for instance, with exposures which were not taken
with SIDEXIS.
The display can, however, be switched to millimeters via the
"Adapt
measurement"
function (see section "Correcting the results of a length
91]").
CAUTION
There are different magnification factors for TSA exposures with an
ORTHOPHOS XG Plus!
Please note that the magnifications of the partial images vary according to
the technique concerned.
