6 Image Acquisition
After adjustment, the LVOT spectrum tracing and calculation results display in real time.
7. Press the <Freeze> key to freeze the image, and check the Smart VTI calculation results.
If necessary, you can edit the LOVT spectrum manually:
a. Tap [Edit VTI] on the touch screen.
b. Press the <Cursor> key to activate the cursor.
c. Move the cursor to the spectrum tracing line and press the <Set> key.
d. Use the trackball/trackpad to trace a line.
After tracing, the calculation results display in real time.
8. Tap [Save VTI] to save the Smart VTI calculation results of the current cardiac cycle to the
database.
9. Tap [Graph] to check the quantitative index trend curve.
VTI, SV, and CO have different trend curves and are differentiated by colors. A maximum of 6
sets of Smart VTI results can be saved and displayed.
6.13 Smart IVC
Smart IVC is used to automatically measure the IVC inner diameter and calculate the change rate in
the B mode image. Measure the IVC (Inferior Vena Cava) in real time, and the system
automatically tracks and measures the changes of IVC inner diameter. It can be used to assist in
treatments, such as volume estimation and fluid infusion.
TIP:
• Smart IVC is an option.
• Smart IVC supports calculation in both real time and freeze modes.
–
Enable Smart IVC in real time. The calculation starts from the current frame and ends
after the image is frozen.
– Enable Smart IVC in freeze mode or from the cine file. The calculation starts from the
current frame and ends at the last frame. If the cine length is no longer than 10 seconds, it
is allowed to calculate in retrospective from the current frame after the cine length reaches
10 seconds.
Perform the following procedure:
1.
Select an appropriate probe and exam mode.
2. Move the probe to gain an appropriate IVC long axis image.
