6 Image Acquisition
– Preview report: Select [Preview] to preview the report. The RIMT mean value, standard
variance and ROI length of the patient's previous exams (including the current exam) are
displayed.
For details about the report, refer to the Operator’s Manual Advanced Volume.
7. Select [RIMT] again to exit.
6.15 Contrast Imaging
The contrast imaging is used in conjunction with ultrasound contrast agents to enhance imaging of
blood flow and microcirculation. Injected contrast agents re-emit incident acoustic energy at a
harmonic frequency much more efficient than the surrounding tissue. Blood containing the contrast
agent stands out brightly against a dark background of normal tissue.
• Set MI index by instructions in the contrast agent accompanied manual.
• Read contrast agent accompanied manual carefully before using contrast
function.
• Make sure to finish parameter setting before injecting the agent into the patient to avoid
affecting image consistency. This is because the acting time of the agent is limited.
• The applied contrast agency should be compliant with the relevant local regulations.
6.15.1 Basic Procedures for Contrast Imaging
Perform the following procedure:
1. Select an appropriate probe, and perform 2D imaging to obtain the target image, and then fix
the probe.
2. Select [Contrast] to enter the contrast imaging mode.
3. Adjust the acoustic power experientially to obtain a good image.
Set [Dual Live] to be “On” to activate the dual live function. Observe the tissue image to find
the target view.
4. Inject the contrast agent, and set [Timer 1] at “ON” to start the contrast timing. When the timer
begins to work, the time will be displayed on the screen.
5. Observe the image, use [Pro Capture] and [Retro Capture] button to save the images.
Select the Freeze button to end the live capture.
Perform several live captures if there are more than one interested sections.
For setting cine length in contrast imaging mode, see the Setup chapter.
6. At the end of a contrast imaging, set [Timer 1] at “OFF” to exit the timing function.
Perform steps 3-6 if necessary.
For every single contrast imaging procedure, use [Timer 2] for timing.
If necessary, activate destruction function by setting [Destruct] at “ON” to destruct the micro-
bubbles left by the last contrast imaging; or to observe the reinfusion effect in a continuous
agent injecting process.
