Preferences: Hip Analysis
The following figure shows the default Hip Analysis parameters. The default settings should be effective for
most scanning situations.
Figure 3-13:
The default Hip Analysis Parameters
Note:
WHAT TO DO: To restore the
default
Analysis parameters, click
and
. This will restore the defaults for
all
scan types.
Note:
WHAT TO DO: To
change
the default Analysis parameters, access the Scanner Preferences
window from the main Database Navigator window as described next.
If it is not already open, click on Edit > Scanner Preferences > Analysis tab.
Locate the Hip analysis parameters in the window (shown above).
Select and change any of the analysis parameters (see Parameter Descriptions below).
Click
and
at the bottom of the window. These settings now become the
default settings until changed again.
PARAMETER DESCRIPTIONS:
Femoral Neck Length: Femoral Neck Length determines the length of the region of interest along the
femoral neck axis. 1.5-cm is recommended because the longer length ensures better precision. The soft-
ware will automatically default to 1-cm if unable to attain a 1.5-cm region.
High Density Point Exclusion: when checked (enabled), it will exclude data points with a density >3.75
g/cm
2
from the analysis. In addition, the note “HD Point Exclusion” will be printed under the image of the
Bone Exam Report.
Caution:
Norland strongly recommends operating the system with the High Density Point Exclusion
box un-checked (disabled), in order to provide consistent results for trending. The option should only
be turned on for individual scans when needed to remove artifacts from the scan.
Alternate R-Value Analysis: if checked (enabled), the software algorithms will first use standard methods
to analyze hip data. If the computed R-value is determined to be outside of an acceptable range, a second
analysis method will automatically be invoked to analyze the hip scan data.
An R-value is a computed value used during the analysis process to allow the software to estimate the
amount of soft tissue above and below bone. In some individuals with very low density, the routine
algorithms for calculating the “R” value do not allow for the proper processing of hip data.
Ward’s Region: is the minimum BMD Region automatically defined by the software. It is un-checked (dis-
abled) by default.
