When entering contrast imaging mode, the screen displays the contrast image. If the [Dual

image (marked with “ ”) are displayed (the two window positions can be changed).
Parameter area displays as follows:

To adjust the contrast image as well as the tissue image, use the left/right keys of soft
menu controls <4> to switch between the menus of tissue image and contrast image.
The parameters in Contrast mode are similar to those in B mode. See chapter B for details.
Special Contrast imaging parameters are introduced below.
Timer
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 image, the
corresponding time can be seen.
Timer 2 stops timing when a contrast exam is frozen, and after unfreezing the image
Timer 2 is off.
NOTE:
The starting time displayed may be inconsistent with the actual one due to
system error or some other human error. Check the agent-injecting time.
Set [Timer 1(2)] to “ON” to start timing from the moment you inject the contrast agent. The
screen displays the times in the bottom-right corner.
