ScanNav Anatomy Peripheral Nerve Block (PNB)

Real-time AI assistant for training and clinical practice of ultrasound-guided regional anaesthesia

ScanNav Anatomy PNB is designed to enhance the accuracy and standardisation of ultrasound image interpretation by providing a real-time colour overlay of key sono-anatomical structures.

This enables qualified healthcare professionals to perform more ultrasound-guided regional anaesthesia with safety and enhanced accuracy.

Features

Peripheral Nerve Blocks

ScanNav Anatomy PNB supports 9 high-value ultrasound guided regional anaesthesia procedures

In real time, ScanNav Anatomy PNB automatically identifies and provides coloured highlights of key anatomical structures relevant to each peripheral nerve block procedure.

The interactive interface allows users to adjust the intensity of coloured highlighting and view native and anatomy highlighted images side by side.

3D Reference Material

In-built reference material for each of the 9 PNB procedures.

Block-specific 3D reference material provides an overview of procedure ergonomics, such as probe positioning, a refresher on anatomy, and scanning technique for the selected block.

Compatibility

Designed to be compatible with general purpose ultrasound machines

ScanNav Anatomy PNB uses the HDMI or DVI feed from your ultrasound machine without interfering with the native scan, allowing the user to be fully in control of their workflow.

ScanNav Anatomy PNB will help tip the balance of safety and confidence in favour of performing regional anaesthesia. Our aim is to make a real clinical difference to patients by increasing the availability of regional anaesthesia through cutting edge technology

Frequently Asked Questions

How do I check if the ScanNav Anatomy PNB will work with my ultrasound device?

ScanNav Anatomy PNB is designed to work with most modern ultrasound machines however, there are some minimum requirements that your ultrasound system needs to have, which are:

  • An HDMI, or DVI external video output
  • A resolution of 640×480 or better with a framerate of 15 fps or higher
  • A high frequency linear and/or lower frequency curvilinear probe
  • It will not work on any hand held or portable ultrasound probes (e.g Butterfly)

Does ScanNav Anatomy PNB store or record any data?

ScanNav Anatomy PNB is a real-time solution which uses the HDMI feed from your ultrasound machine and does not store or record any data or images.

Will ScanNav Anatomy PNB interfere with my ultrasound scan?

ScanNav Anatomy PNB connects to general purpose ultrasound machines using a standard HDMI / DVI output connection. This does not interfere with or obstruct the standard operation of the ultrasound machine.

Who will benefit from ScanNav Anatomy PNB?        

ScanNav Anatomy PNB is intended to assist qualified healthcare professionals in the identification of anatomical structures for ultrasound-guided interventional procedures.

The clinical benefits of ScanNav Anatomy PNB are as follows:

  • Support the performance of healthcare professionals who are suitably qualified but who perform ultrasound-guided procedures on an infrequent basis.
  • Enhance the accuracy and standardization of ultrasound image interpretation by making it easier to identify key anatomical structures.

Does the system need an internet connection to function?

ScanNav Anatomy PNB is a real-time solution which uses the HDMI feed from your ultrasound machine and does not require an internet connection to function. Its Ethernet port is disabled and the system does not support wireless connectivity.

What is the difference between ScanNav Anatomy PNB and ScanNav Anatomy PNB Trainer?

  • ScanNav Anatomy PNB is a licensed medical device (CE approved) in the UK and Europe. Currently available for sale in the UK only.
  • ScanNav PNB Trainer is available in the USA for training in a non-clinical environment only. It is not licensed for clinical use in the USA.

Can you project the ScanNav screen onto a bigger screen for teaching?

Yes, there is a HDMI output on the ScanNav panel PC allowing you to present the ScanNav display on a bigger screen. The HDMI output has a resolution of 1200×800. See the Instructions for Use for more details.

Clinically Validated

In a validation study 3, experts in regional anaesthesia judged the AI-driven colour highlighting to be helpful for identifying anatomical structures in 1,330/1,334 cases (99.7%), and for confirming the correct ultrasound view in 273/275 ultrasound scans (99.3%).
