An eye on the patient
with ARNI

 The project ARNI ("Augmented Reality Needle Intervention") is funded by the German Ministry of Research and Education (BMBF).

ARNI started on 01.01.2019 and originally had a duration of 30 months, but could be extended by 12 months until 30.06.2022.

The project parties are:

Ultrasound-guided Augmented Reality Needle Intervention with Hololens 1

In paediatric emergency care establishing intravenous lines (IVs) are one of the most basic skills but can be challenging due to the particular situation of young patients: small vessels, agitated patients and nervous parents often complicate the situation. Ultrasound (US) support has proven to be very helpful in these challenging cases.

ARNI supports physicians during vascular needle interventions by visualizing all relevant information for the intervention at the site of the event/procedure. There is no need for a constant change of view between the monitor of the ultrasound device and the site of the intervention.

Further developments deal with the integration of ARNI in combined AR and VR environments (mixed reality) in order to give remote experts the possibility to be virtually present during the intervention. A combination of ARNI with a 3D scanner such as the Microsoft Kinect allows virtual work in volumetric environments.
