B.2.3 DualFemur™ Acquisition
NOTE: DualFemur acquisition is not available for the Compact DPX-IQ. In
software versions earlier than 4.6d, DualFemur acquisition begins
with the right femur.
During a DualFemur™ acquisition, the program acquires the left femur first: you
must position the laser light for the left femur before you start a DualFemur™
acquisition. When the scan is started, the program 1) acquires a scan image for the
left femur, 2) automatically moves the scan arm and detector to locate the start
position for the right femur, and 3) acquires a scan image for the right femur.
User intervention is NOT required between left and right DualFemur™ scans.
However, the program may not locate the start position for the right femur due to
incorrect patient positioning or unusual anatomy. If the program can not locate the
start position, a message is shown which prompts you to “Adjust position for the
Right Femur.”
Abort a DualFemur™ Acquisition
Abort during acquisition: Select
#
to abort the scan while the program is
acquiring the left or right femur. Refer to section 2.3.5 for more information.
Abort between left and right femur scans: You can select
#
to abort the scan
while the scan arm and detector are moving to locate the right femur start position.
The message that follows is shown:
Continue with SmartFemur positioning (Y/N) ?
Select Y to continue the right femur scan. If you select N, the message that follows is
shown:
Manually adjust start position for the right femur (Y/N) ?
Select Y to manually adjust the start position for the right femur, or select N to abort
the right femur scan. If you select N, the left femur scan is still available for analysis.
B.3 Femur Image Analysis
NOTE: In most cases, the software will accurately analyze the scan image.
However, unusual anatomy or incorrect patient positioning may
require you to complete manual adjustments to the scan image or
ROI position.
The procedure that follows gives the basic steps necessary to complete a femur image
analysis. Refer to section B.4 for more information.
1. Refer to section 2.4.1 to select a patient scan file for analysis.
NOTE: If you are analyzing DualFemur™ scans, both the left and right
femur scans have the same acquisition date as shown on the Scan
Directory screen.
