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.

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.
