2. Get magnetic devices prepared. Connect the magnetic devices. Power on the magnetic
navigator.
3. Activating the magnetic positioning:
a. Tap [Fusion] on the touch screen or user-defined key to enter Fusion Imaging mode (see
also Chapter 12 Setup for key preset operations). Tap [Tracking System] on the touch
screen. The magnetic navigation positioning is activated when the soft key becomes
highlighted (it is usually activated by default).
b. Checking indicator. The Fusion Imaging works when the indicator becomes green.
4. Acquire/import CT/MR/PET/freehand volume data. XX
You can load PET volume data and CT volume data, and tap [Multi Data Regi] to register the
PET image with CT image. Tap [Mark on Multimodality] to make marks on CT and PET
images. Tap [Exit]. Then tap [Multi Data] to select “PET-CT”. The PET-CT volume data will
be used in later registering with ultrasound image.
NOTE:
• The Ultrasound System sets CT/MR/PET/freehand volume data to 3-dimensional
display automatically. One of anatomical planes (2-dimensional image) appears on the
screen.
• After freehand volume data is imported or acquired, the system registers freehand
volume data with the ultrasound plane automatically. Do not move the magnetic
generator and the patient for any circumstances after the freehand volume data is
imported or acquired. Otherwise, the registration display for freehand image and the
ultrasound image is affected.
5. The brightness and the grey level of loaded data can be completed via Window Width and
Window Level. Set Window W and Window L.
6. Obtain an optimum plane as the registration plane from CT/MR/PET image.
NOTE:
Registered with the ultrasound plane). (For freehand volume data, skip steps 6-8.
It is suggested that the plane concentrated with blood vessels, organs, tissue margins, lesions is
optimum for registering.
Tap [View Type] to change CT/MR/PET plane (transverse plane/coronal plane/sagittal plane).
The pan (using the trackball), the shift or the rotation (along Z-axis) can be completed on CT/
MR/PET plane until an optimum plane for registering appears.
See XX for CT/MR/PET image operations.
7. Obtain an ultrasound plane consistent with CT/MR/PET plane (taking as the registration
plane) from human body in ultrasonic scan.
NOTE:
• It is usually easier to obtain an optimum plane when the probe sweeps.
• The registration is only approved when the image is frozen after pressing <Freeze>.
8. Data registering (first time registering).
a. Tap [Registration] to activate the registration. Tap [View Type] to select.
b. To register the ultrasound image with the CT/MR/PET image, perform the following
procedures to set CT/MR/PET image.
–
The icons for different plane operations appear after pressing <Set> for multiple
times.
