• The Fusion Imaging is contraindicated to the person wearing the internal pacemaker, cochlear
implant or nerve stimulator. People wearing the implant or intra-corporeal devices should keep
one-meter away when the magnetic generator starts working.
Needle navigation feature combines technology of real-time imaging and mini-magnetic locating to
provide GPS real-time guiding biopsy. Based on the sensors attached to the probe and needle,
magnetic navigator provides the related 3-dimentional orientation of the needle and the ultrasound
image plane.
There are two types of needle navigation: in-plane and out-plane. In-plane navigation applies to
needle path inside the ultrasound image plane and out-plane navigation applies to needle path not
inside the ultrasound image plane.
17.3.1 Basic Procedures for Needle Navigation Guiding
Needle navigation guiding biopsy procedure under non-Fusion mode
Perform the following procedure:
1.
Connect all accessories of magnetic navigator. Refer to chapter “6.15.2 Magnetic Navigator”
and “17.3.2 Installation” for details.
2. Activate needle navigation guiding feature and select needle type and length. Perform
accuracy verification. For details, refer to chapter “17.3.3 Accuracy Verification”.
3. Perform ultrasound image scanning and confirm position/size/structure of tumor/lesion. Mark
the lesion. For details, refer to chapter “17.3.4 Mark”.
Tap [SSC] to perform acoustic speed correction.
4. Place the needle next to the probe and adjust the biopsy guideline on the image for
recommended needle position and angle.
The guideline turns green if it is able to reach the lesion mark.
5. Perform biopsy by the guideline.
The distance indicating box shrinks by the time needle tip goes towards the lesion mark. When
the tip reaches the lesion mark, the box turns green and merges with the tip.
For detailed procedure description, refer to chapter “17.3.5 Screen Display in the Guiding”.
6. Save the single-frame and multi-frame image if necessary.

3. Enter Fusion imaging and load CT/MR/PET/freehand data. Refer to step 1-5 in chapter
“6.15.4 Basic Procedures” for details.
4. Mark the tumor/lesion on CT/MR/PET/freehand image. For details, refer to chapter
“6.15.6 Marks”.
Tap [SSC] to perform acoustic speed correction.
5. Register CT/MR/PET/freehand data. For details, refer to chapter “6.15.4 Basic Procedures”.
6. Place the needle next to the probe and adjust the biopsy guideline on the image for
recommended needle position and angle.
