8 Contrast Imaging
For every single contrast imaging procedure, use [Timer 2] for timing.
If necessary, activate destruction function by tapping [Destruct] to destruct the micro-bubbles
left by the last contrast imaging; or to observe the reinfusion effect in a continuous agent
injecting process.
7. Exit contrast imaging.
Tap [B] to return to B mode.
8.2 Image Parameters
When entering contrast imaging mode, the screen displays the contrast image, and if [Dual Live]
item on the touch screen is “ON”, both the contrast image (marked with “C”) and tissue image
(marked with “T”) are displayed (the two window position can be changed).
Parameters in Contrast mode are similar to those in B mode; please refer to B chapter for details,
special Contrast imaging parameters are introduced in the following.
Image Optimization
The parameters in Contrast mode are similar to those in B mode. See B mode imaging parameters
for details. Special imaging parameters are introduced below.
Timer
The starting time displayed may be inconsistent with the actual one due to system error or some
other man-made mistakes; please check the agent-injecting time.
The two timers are used to record the total time of the contrast imaging and the single time of one
contrast exam.
After the image is frozen, Timer 1 is still running, and after unfreezing, the corresponding time can
be seen.
Timer 2 stops timing when an exam is frozen, and after unfreezing, Timer 2 is off.
Activate [Timer 1(2)] to start timing from the moment you inject the contrast agent. The screen
displays the times in the bottom-right corner.
• The time begins at 0.
• In live mode, the elapsed time is displayed. For example, 00:00:08 means the elapsed time is 8
seconds.
• If the image is frozen during timing, the timer stops working and the elapsed time is displayed.
• Turn off [Timer 1] or [Timer 2] and the timer stops running.
Micro-bubble Destruction
Use the contrast imaging according to the residual level of the micro-bubbles,
using contrast imaging continuously may result in human harm.
Destruct the micro-bubbles left by the last contrast imaging; or to observe the reinfusion effect in a
continuous agent injecting process.
Tap [Destruct] to enable the micro-bubble destruction function:
