Onvision® Needle Tip Tracking
Choose a category or subcategory
Ultrasound guidance system for peripheral nerve blocks
Onvision is an Ultrasound based Needle Tip Tracking Technology for Peripheral Nerve Blocks that works exclusively with Xperius® Ultrasound System and the dedicated Stimuplex Onvision needle.
In real-time, Onvision accurately indicates where the needle tip is inside the body, in or out of plane. It allows Anesthesiologists to align the needle with the probe in a user-friendly manner.

Needle guidance to the point
Our ambition is to make Peripheral Nerve Blocks (PNBs) more straightforward for healthcare workers and safer for patients. The needle tip position is indicated by circles that are displayed on the ultrasound image. The circles appear automatically when the needle tip sensor enters the imaging plane.
Onvision helps to see the needle tip and to master the needle beam alignment. With Onvision, users experience a real time guidance which gives them confidence in block success when performing both in and out-of-plane blocks.2

Onvision® Needle Tip Tracking Demonstration Video
Ultrasound based Technology for needle guidance
The dedicated Stimuplex Onvision Needle with embedded tip sensor allows the exact detection of the tip location and display this information in real time on the live Xperius Ultrasound image. Needle tip tracking can be used for 2D Mode with the Nerve 0‑4 cm and the Nerve 4‑6 cm preset on the L12-4 transducer and Nerve 6+ cm presets on the C5-2 transducer.
Technical working principle
The Onvision system detects the exact location of the Stimuplex Onvision tip sensor using the three dimensional space of the Ultrasound beam. The technology combines ultrasound image data from the ultrasound system with signals from the needle to accurately locate the position of the sensor on the Onvision Needle. This projects the position of the sensor by overlaying a circle over it on the ultrasound image in real time.
