5-122 Image Optimization
the probe scan orientation and position to obtain the CT/MR plane which is identical
with that on the ultrasound image (the CT/MR plane moved).
b) Tap [Freeze US] and [Freeze MPR] to highlight the soft keys, tap [Confirm Registration] to
complete the fine tuning.
Use the plane concentrated with the patient’s lesions to perform the fine
tuning.
The adjusting levels of the CT/MR plane and the ultrasound plane become
finer after entering the fine-tuning. The ultrasound image and CT/MR image
can precisely be registered after several times of fine tuning.
Freeze the ultrasound image and CT/MR image simultaneously after the
fine tuning. Tap [Register]→[Confirm Registration] to make the fine tuning
worked.
11. Respiration compensation (it is suggested that the respiration compensation should be
operated according to your demands).
The respiration compensation can possibly enhance the fusion accuracy of the ultrasound
image and CT/MR image, and reduce the aspiration motion effects to the image. See also
Chapter 5.16.7 Respiratory Compensation.
12. Conduct the ultrasonic exam and operation after the registration is completed.
13. Freeze the ultrasound image to save the single frame image or multi-frame cine.
Marks (setting the mark based on your need)
Mark the lesion position on CT/MR image. See also Chapter 5.16.6 Marks.
Note: mark the tumor on CT/MR image after CT/MR data is imported. Generally, it is available to
mark the tumor before/during/after the registration.
Ultrasound Contrast Fusion (conducting the Contrast Fusion based on your need)
Inject the contrast gel after the registration is completed. Enter Ultrasound Contrast Fusion imaging
mode. See also Chapter 5.16.8 Contrast Fusion Imaging.
Data registration of same patient/body part in different phases
When different phases of CT/MR data from the same patient/body part exist and one CT/MR data
has been registered already, system will register the data by previous information if other phases
data are imported.
