The user may modify the offset or length while performing the
exam, in case these are not set to optimal dimensions.
To modify Protocol defaults
1. Set the Protocol button ON or OFF.
2. In case Protocol is ON: adjust the Offset and Length
values.
3. Press the Store default soft-key to store the status of
"protocol" button ON or OFF and the current settings of
Offset and Length, to be used in the future exams.
4. The default settings may be defined differently for the CCA
and the ICA.
Note: When adjusting the offset for the ICA, the offset
values are negative, as the ROI is located to the left of the
vertical reference marker.
IMT trace approval
Since the IMT measurements are done semiautomatically, the
operator has to approve the detection by visual inspection
before storing the results in worksheet and report.
• If the traces fit both layers of the intima-media walls,
approve the measurement by selecting Transfer in the
Measurement menu.
Once transferred, the calculations can be viewed in the
worksheet and report.
CAUTION
Measurements that are not approved will not be saved.
CAUTION
Any image adjustments (e.g. Gain or zoom) on approved
(transferred) measurements will unassign the measurements.
Press Transfer to approve the measurements again.
