times, never at an angle. The movement is repeated until the
measurement cycle is complete. A single scan movement
through 180 degrees should take 4-5 seconds.
Figure 15.7 The range of probe movement during the scan
To ensure accurate and reproducible results, note the
following:
•
One end of the probe surface should follow the marked
point on the skin at all times.
•
Never hold the probe at an angle to the surface of the limb.
The probe should be held so that the short dimension of its
surface is tangent to the bone while its long dimension is
parallel to the bone axis.
•
Do not use a circular motion. The probe movement should
follow parallel to the marked line.
•
Scan approximately 180 degrees but no further.
•
Check to ensure that a scan movement through 180 degrees
takes about 4-5 seconds. The scan is being conducted too
slowly or too quickly if the movement takes longer or
shorter, respectively, than this amount of time.
•
Maintain the probe’s surface in contact with the patient’s
skin throughout the scan. No part of the probe surface
should be raised from the skin at any point during the scan.
To scan, move the probe
first in the medial direc-
tion, about 90 degrees,
then back to the start
point and further in the
lateral direction, again 90
degrees, and return to
start.
