The Line Profile
The Line Profile shows the information that follows:
• Baseline —The program calculates results from the area above the baseline (
➊
).
• High Density Points —The High Points on the profile show areas of high
density: dense bone (
➋
) and implant material (
➌
).
• Edge Markers —The edge markers (
➍
) are used to isolate the bone from the
implant. The high points contained inside the area between each pair of markers,
and above the baseline, are used to calculate results.
• Soft Tissue Points —The low points on the profile (
➎
) show areas of
soft tissue.

Examine Edge Markers
Refer to the information that follows to make sure the edge marker positions are
correct (figure G-8):
• Pelvis Edge —If the pelvis is shown on the scan image, the markers are on each
edge of the pelvis bone points (
➊
and
➋
).
• Left Femur Edge —The left femur edge marker (
➌
) is on the last soft tissue
point before the bone points start up to the implant points.
• Left Implant Edge —The left implant edge maker (
➍
) is on the first
implant point.
• Right Implant Edge —The right implant edge marker (
➎
) is on the last
implant point.
• Right Femur Edge —The right femur edge marker (
➏
) is on the point
immediately after the bone points join the soft tissue points.
NOTE: Change edge markers only if they are obviously not correct. Let the
program calculate the edges for you.
