Interventional Procedures
WARNING: Percutaneous procedures always involve heightened risk to the patient and to the
operator handling biopsy needle guides. Clinicians using Siemens recommended biopsy devices
under ultrasound guidance should be trained and must observe proper needle insertion
sequencing with the needle guide in order to avoid undue discomfort and unnecessary risk and
injury to the patient.
You can perform interventional procedures, including ultrasound-guided ablation and biopsy
procedures, using the blended image as a reference. Biopsy controls are available only when
Scan is activated.

Before you perform an interventional procedure, you can create planning data such as
landmarks, segmentations, and planned needle paths.
See also: Planning Data, p. 9-17
To track the position of the needle:
Prerequisite: You must connect a needle-tracking sensor to port 4 on the tracking system and a
transducer sensor to the port associated with the active transducer.

1. Select Scan to display the blended image.
2. To view both the reference image and the ultrasound image select the required display
format (1:1, 2:1, or 1:3).
The system displays the reference data on the left side of the screen and the ultrasound
image on the right side of the screen.
3. Select Track Needle .
The system displays the tracked needle on the ultrasound image. Red indicates the part of
the needle on the right side or above the ultrasound image plane, depending on the
orientation of the transducer. Blue indicates the part of the needle on the left side or below
the ultrasound image plane, depending on the orientation of the transducer.
The system displays an indicator (green circle) when the needle is more than 5° outside
the imaging plane. The needle tip is pointing to the location identified by the green circle
(indicator). The circle decreases in size to a point as the needle tip nears the image plane.
