6 Image Acquisition
– 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).
6.20.6 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.
6.20.7 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.
6.20.8 Data Export
The system provides data exporting function, so that you can export calculation result for analysis
(for instance, SPSS analysis).
Tap [Data Export] on the touch screen, to export analyzed data of each segment in .csv format.
6.21 Application
This function is used to evaluate respiratory failure, shock and trauma in emergency treatment,
quickly determine the cause of respiratory failure, identify the type of shock, and determine
whether there is fluid in the trauma.
Perform the following procedure:
1. Select a probe and click [Application] in Function menu to enter an application.
2. Select the site or section for scanning.
– Select [Help] to view help information about the scanning of the section.
– Select [Setup] to set the section type.
3. Adjust the image parameters, select the annotation information, and save the image.
4. Repeat step 2~3 to scan all parts and sections.
5. Click [Summary] to view all comments and images.
6. Click [End Application] to end the exam.
