3. Roll the trackball to locate ROI over the target area. The dotted line of the ROI is in the middle of the
blood vessel. Press <Set> to confirm the position and size of the ROI.
Note RIMT inside ROI is highlighted in red, yellow and green. There is no gap between the
filling area and the vascular wall.
The green color indicates the normal acceptable value.
The red color or yellow color indicates the abnormal unacceptable value.
4. Tap [Start Calc] to measure RIMT of left carotid and right carotid. Six RIMT values (each RIMT value
represents maximum IMT value within one cardiac cycle), RIMT average value (arithmetic mean
value of the 6 RIMT values), SD (standard deviation of the 6 RIMT values) and ROI length are
displayed in the result pane.
5. Tap [Accept Result] or press <Set>. The image is frozen. You may save single frame image and
results to the result pane.
Tap [Cancel Result] to recalculate RIMT. Perform 4~5 step to reset the RIMT.
6. Tap [Report] to view the report. Only last acceptable data, including RIMT on left and right carotid, is
in the data sheet. You can perform:

Deleting data: select RIMT data from the data sheet. Tap [Delete Rows] to remove the RIMT
data of the left and the right carotid.

Viewing graphic: tap [IMT Trend] to view the RIMT graphic. The data on the graphic is same
with these in data list. The RIMT average value, SD and ROI length of the exams are displayed
at the bottom of the graphic (including the current exam).

Previewing the report: tap [Preview] to show IMT. The RIMT average value, SD and ROI length
of the exams are displayed.
See Advanced Volume for the settings, print, saving or loading the report.
7. Tap again [RIMT] to exit.
5.19 R-VQS
R-VQS (RF-data based quantification on arterial stiffness) tracks movements of the upper and lower
vessel walls and measures vessel diameter, displacement, hardness coefficient and
PWV(dimensionless pulse wave velocity).
Hardness coefficient: Arterial stiffness is changed with the blood pressure changing. The bigger the
value the higher the stiffness.
PWV (dimensionless pulse wave velocity) reprerents the transmit speed of pulse wave. The bigger the
stiffness parameter the higher the PWV.
Note:
Vascular Package should be configured.
R-VQS is an option. Only linear probe under Carotid exam mode supports this feature.
Basic Procedures
1. Select a probe and carotid exam mode. Perform B real-time imaging and search for carotid vessel.
Try to place the vessel on the image horizontally.
2. Tap [R-VQS] and roll the trackball to locate green ROI box on the target area. Dotted line of the ROI
lies in the middle of the vessel and divides the vessel upper wall and lower wall. Use <Set> and
