Strato X User Manual - Image Works

USER'S MANUAL
General instructions for use
These offset values, that can be input on the system when it ask for
them, are measured with the following steps using longitudinal and
transversal images of the point of interest.
1. Place the radiograph on the lighted viewing plane, taking into
account that the longitudinal image is on the left whichever is the
interested teeth.
2. Place the special ruler (refer to Figure 24) on the film; care has to be
done on such a way to have the four lines (two upper and two on
lower) defining the limit of the image exactly on the borders of the
image (please refer to Figure 22). In this way, the central line of the
ruler, that now is exactly placed in the middle of the image, defines
the point of interest defined by STRATO X. Now measurements of the
offset can be made, having this line as a reference; the ruler has also
the positive and negative indication of the measures.

3. Measure first, using the ruler, the distance from the real point of
interest to the reference line, considering also the sign: + if the
point of interest is on the right side of the reference line, - if it is on
the left one. This value is the longitudinal displacement; it has to be
input (if needed) on STRATO X when display showa the following
message:
LONGIT OFFS:>+00
On the same way, it is possible to measure the transversal
displacement (offset).
