8. If the contour is not optimal, adjust Trace Fit to modify the
traces according to different threshold values.
If the contour is still not optimal, try to perform the IMT
measurement on another frame, preferably close to the end
diastole.
IMT trace approval
NOTE: Erroneous contour detection of the Intima and Media layers may
lead to incorrect measurement results. The contour detection
should be visually checked and edited if required.
Since the IMT measurements are done semi-automatically, the
operator has to approve the detection by visual inspection
before storing the results in worksheet and report.
1. If the traces fit both layers of the posterior wall, approve the
measurement by selecting Transfer in the Measurement
menu.
Once transferred, the calculations can be viewed in the
worksheet and report.
NOTE: Measurements that are not approved will not be saved.
NOTE: Any image adjustments (e.g Gain or zoom) on approved
(transferred) measurements will unassign the
measurements. Press Transfer to approve the
measurements again.
Vascular AutoDoppler
Vascular AutoDoppler enables the Vivid S70 / S60 to detect and
identify a cardiac cycle, and allows measurements and
calculations during live timeline imaging while the image is
frozen or in cine.
