6 Image Acquisition
Curve Display
Select [Parameter], the system provides different curves of different segments for observation.
•
General
–
Speed curve: The X-axis represents time (s); the Y-axis represents velocity (cm/s).
– Displacement curve: The X-axis represents time (s); the Y-axis represents displacement
(cm).
• Long axis section
–
Volume: The X-axis represents time(s); the Y-axis represents volume (ml).
– Strain curve (Longitudinal, Transversal): The X-axis represents time (s); the Y-axis
represents strain deformation of the tissue (%).
– Strain-rate curve (Longitudinal, Transversal): The X-axis represents time (s); the Y-axis
represents strain by time (s
-1
).
• Short axis section
–
Area curve: The X-axis represents time(s); the Y-axis represents area (cm2).
– Strain curve (Radial, Circumferential): The X-axis represents time (s); the Y-axis
represents strain deformation of the tissue (%).
– Strain-rate curve (Radial, Circumferential): The X-axis represents time (s); the Y-axis
represents strain by time (s
-1
).
– Circumferential Rotation curve: The X-axis represents time (s); the Y-axis represents
rotation of the tissue (Deg).
– Circumferential Rotation Rate curve: The X-axis represents time (s); the Y-axis represents
rotation by time (Deg/s).
Torsion & Torsion Rate Curve
The system provides left ventricular torsion data based on short axis sections of PSAX AP and
PSAX B. Torsion is acquired by calculating difference of apex and base of the heart.
Torsion = PSAX AP Rot. - PSA XB Rot.
• The X-axis represents time (s).
• The Y-axis represents tortion by time (Deg/s).
6.15.6 Bulleye
After tracking, the system can display Bull’s Eye graph, so as to judge reverse movement or scope
of myocardium.
1.
Tap [Bull’s Eye] on the touch screen to turn on the function:
You can acquire:
– Time to peak value and peak value of the 17 segments (similar to 16 segments);
– Display measurement result EDV/ESV/EF/TPSD.
2. Use [Parameter] on the touch screen to see different parameter bull’s eye graph.
“-” will display in the table to indicate those segments that are not well tracked.
6.15.7 Measurement/Comment
Under tissue tracking QA mode, only Time measurement is available. For details, please refer to
Operator’s Manual
Advanced Volume .
Comments and Body Mark operations are the same as in other modes.
