6 Image Acquisition
Operator’s Manual 6 - 19
NOTE:
• iScape panoramic imaging is intended for use by well-trained ultrasound operators or
physicians. The operator must recognize image items that will produce a sub-optimal or
unreliable image.
• If the image quality cannot satisfy the following criteria, you shall remove the image and
capture it again.
–
The Image must be continuous (no part of an image moves suddenly or disappears.)
– No shadow or absent signal along the scan plane.
– Clear profile of anatomy through the entire scan plane without distortion.
– Skin line is continuous.
– The images are captured from the same plane.
– There are no large black areas in the image.
6.9.4 Cine Review
Tap [Review Cine] on the touch screen in panoramic image viewing status to enter cine reviewing
mode. In cine reviewing mode, a frame marker indicates the sequence of the currently reviewed
images in the panoramic image on the left-hand side of screen.
In cine review status:
•
Use the trackball/trackpad to review the captured images frame by frame.
• Tap [Auto Play] to start or end auto play.
• In auto play mode, tap [Auto Play] on the touch screen, or press/rotate the corresponding knob
to change the play speed. When the speed is off, the system exits auto play mode.
• Review to a certain image. Tap [Set Begin] to set the start point. Review to another image. Tap
[Set End] to set the end point. In auto play mode, the review region is confined to the set start
point and end point.
• Tap [iScape View] > [Overview] on the touch screen to exit cine review mode. The panoramic
image displays.
• In cine review mode, press <Freeze> on the control panel to return to the acquisition
preparation status.
6.10 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, coefficient of hardness 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) represents 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.
Perform the following procedure:
