13.3.1 Basic Procedures for Needle Navigation Guiding
Needle navigation guiding biopsy procedure under non-Fusion mode:
1. Connect all accessories of magnetic navigator. Refer to chapter "5.17.2 Magnetic Navigator" and
“13.3.2 Installation” for details.
2. Activate needle navigation guiding feature and select needle type and length. Perform accuracy
verification. For details, refer to chapter “13.3.3 Accuracy Verification”.
3. Perform ultrasound image scanning and confirm position/size/structure of tumor/lesion. Mark the
lesion. For details, refer to chapter “13.3.4 Mark”.
Tap [SSC] to perform acoustic speed correction. For details, refer to chapter “5.2.3 B Mode Image
Optimization”.
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 “13.3.5 Screen Display in the Guiding”.
6. Save the single-frame and multi-frame image if necessary.
