Probes and Biopsy 13-45
13.4 eSpacial Navi
13.4.1 Overview
The eSpacial Navi function builds up the connection between the ultrasound system and the
processed needles. The needle position appears on the image in real time. Meanwhile, the virtual
needle mark guides the needle path on the ultrasound image. Based on the magnetic induction
technology, the eSpacial Navi function aids in and enhance the ultrasound needle guidance.
Only probe L11-3VNs supports the eSpacial Navi function.
Ultrasound images should be referenced during the
whole process of needle guidance.
The magnetizer is a single use device. Dispose of the
magnetizer properly after use.
The needle cap is a sterile, single use device. To
maintain procedural sterility, it is important that the
needle cap is isolated from non-sterile objects.
Keep the magnetizer away from any device that is sensitive to
magnetic fields. Never place or hold the magnetizer within 1 m of
the probe.
The eSpacial Navi system supports only the needle types listed on
the needle list. For details, refer to “13.4.2 Interface”.
Keep the probe away from the source of disturbance, such as metal
objects and magnetized objects.
When used under optimal operating conditions by an experienced medical
professional, the eSpacial Navi system can achieve precision as high as ±2.4mm.
Place the magnetizer in the proper position to prevent the magnetizer from falling off or
becoming damaged.
