6 - 32 Operator’s Manual
6 Image Acquisition
• [A2C]: apical two chamber.
• [ALAX]: apical long-axis view, also called 3-chamber view.
• [PSAX B]: short axis view of base section, short axis view of mitral valve.
• [PSAX M]: short axis view of base section, short axis view of papillary muscle.
• [PSAX AP]: short axis view of apex.
Parameter Adjustment
• [Thickness]: adjusts the tracing thickness, i.e., the distance between the endocardium wall and
the tracking points on the epicardium.
• [Tracking Points]: adjusts the number of points within the segment.
• [Cycle]: select the next cycle.
• [Display Effect]: turns on/off the arrow vector graphical display of the myocardial movement.
• [Velocity Scale]: adjust the scale length of the velocity.
• [Display Style]: display the endometrial, the epicardium, the myocardial or all.
• [Tracking Cycles]: select the cycles to be tracked.
• [Average Cycles]: obtain the average parameter curves of the tissue.
• [Cycle Select]: select among different cycles.
Time Mark
According to the status of the current section, tap the corresponding key on the touch screen to
check the matching time.
•
[AVO]: displays aortic valve open time.
• [AVC]: displays aortic valve closure time.
• [MVO]: displays mitral valve open time.
• [MVC]: displays mitral valve closure time.
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).
