)
at the Spaces/Labels screen to examine baseline and edge markers: the
Profiles screen shows the Line Profile.
NOTE: The Line Profile is an optional feature. Refer to chapter 4 to activate
the “Display Line Profile” option.
The Profiles screen shows an image of the spine and a Line Profile (figure A-8). The
Line Profile uses baselines and edge markers to identify soft body tissue and dense
bone. Baselines and edge markers let the program calculate accurate BMD results.

The Line Profile
The Line Profile shows the information that follows (figure A-9):
➊
Baseline: The baseline is the horizontal line at the bottom of the profile. The
points below the baseline identify soft tissue the program does not use to
calculate results.
➋
High Density Points: The high points on the profile identify high density points
(bone) the program uses to calculate results.
➌
Edge Marker: The circles on the left and right side of the analysis region
identify the edge markers. The high density points contained inside the area
between the edge markers and above the baseline are used to calculate results.
➍
Soft Tissue Points: The low points on the profile identify soft tissue the
program does not use to calculate results.
