Image Optimization 5-85
Timing (If timer is
―ON‖)
In real time mode, the time displayed is the elapsed time.
In freeze mode, the timer stops working, the frozen time is
displayed.
5.12.3.2 Image Optimization
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.
5.12.3.3 Timer
The two timers are used to record total time of contrast imaging and single time of one contrast
exam.
After the image is frozen, Timer 1 is still timing, and after unfreezing the image, the corresponding
time can be seen.
Timer 2 stops timing when one contrast exam is frozen, and after unfreezing the image, the Timer
2 is off.
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.
Set [Timer 1] as ―ON‖ to start the timing at the moment you inject the contrast agent. Here, the
screen displays the times at the lower right corner.
The time begins at 0.
In live mode, there displays the elapsed time. For example, , it means the elapsed time
is 8s.
Freeze the image during the timing, the timer stops working, and there displays the elapsed
time. For example, , it means the elapsed time between begin timing and freeze the
image is 9s.
Set [Timer 1] or [Timer 2] as ―OFF‖, the timer discontinues its work.
5.12.3.4 Micro-bubble Destruction
Function: destruct the micro-bubbles left by the last contrast imaging; or to observe the reinfusion
effect in a continuous agent injecting process.
Entering: touch [Destruct] on the touch screen to enable the micro-bubble destruction function.
Parameters: set the parameters through the touch screen/menu.
DestructAP: adjust the destruct acoustic power by the touch screen/menu item.
DestructTime: adjust the destruct time by the touch screen/menu item.
Use the contrast imaging according to the residual level of the micro-
bubbles, using contrast imaging continuously may result in human harm.
5.12.3.5 Dual Live
In live mode or freeze mode, set touch screen item [DualLive] as ―ON‖ to enable dual live function.
Both the contrast image (marked with ― ‖) and tissue image (marked with ― ‖) are displayed
(the position can be changed). Meanwhile, you can switch to [Contrast] or [Tissue] page to adjust
the corresponding parameters.
