Set a Rim Value
The Rim option sets the distance between the edge marker and the outer edge of the
bone region.
1. From the Profiles screen, select
)
. The number following “Rim =” below the line
profile is highlighted in green.
2. Record the distance (0–10mm) necessary between the bone edge and the
edge marker.
3. Select
0
. The program shows a set of edge markers the distance you specified
from the outside edge of the bone region.
G.3.7 Histograms
Longitudinal Histogram
At the Auto Analysis screen, select
*
to access the Longitudinal Histogram. The
Longitudinal Histogram (figure G-14) shows the density of bone next to the implant.
Use this histogram to monitor bone remodeling along the entire length of the implant.
The program calculates BMD values for the bone regions and shows the values below
the histogram.
Figure G-14. Longitudinal Histogram screen
Transverse Histogram
At the Longitudinal Histogram screen, select
&
to access the Transverse Histogram
screen (figure G-15). Use this histogram to monitor bone remodeling next to
the implant.
The Transverse Histogram gives the bone density of regions next to the implant, much
like the Longitudinal Histogram. However, the bone region on the Transverse
Histogram screen cannot be more than 12 mm tall. In addition, the program does not
calculate BMD values for the regions shown on the histogram.
