The intelligence layer for fluorescence-guided surgery

Transforming fluorescence into real-time anatomical and functional insight during surgery.

For surgeons: talk to us about collaboration Contact
Built for the OR

A smarter way to see fluorescence.

01

The raw signal

Injected ICG fluoresces for a short window. On the endoscope feed the signal is diffuse, and it is read by eye.

02

The reading

Time-series analysis of the same feed separates vessels from surrounding tissue by how the signal arrives and clears.

03

The overlay

The map is drawn on a second monitor. No new instruments, no new steps, no change to the sterile field.

Lineage Founded by Perfusion Tech alumni, in Copenhagen.
Intellectual property Licensed patent families covering the signal method.
Clinical Collaborations with leading Danish cardiothoracic centres are being formalised.
Integration Camera-agnostic: works alongside existing Stryker, Karl Storz, Olympus and Intuitive systems.
Why now

Fluorescence has become infrastructure. Intelligence comes next.

Fluorescence-guided surgery is moving from a niche imaging technique to a routine part of the surgical workflow. The way the signal is interpreted has barely changed.

01

More surgery happens through a camera

Minimally invasive and robotic approaches increasingly make the camera the surgeon's primary view of the anatomy. That makes the information carried in the image more important — and it makes software interpretation possible.

02

Fluorescence is becoming standard infrastructure

Near-infrared imaging is increasingly built into surgical platforms, and ICG is already used across multiple procedures. The hardware and the signal are entering the operating room at scale.

03

The signal is still read by eye

Fluorescence is dynamic, spatial and time-dependent, but most systems still present it as a transient green image. The underlying signal holds far more information than a surgeon can extract visually in real time.

Technology

A noisy feed, read as a time series.

The software under development converts a near-infrared video feed into a structured map of the vasculature. It analyses how the fluorescence signal changes across frames rather than processing each frame on its own.

Segment

Segments and classifies tissue in the field, separating vascular structures from parenchyma.

Track

Tracks that tissue through breathing, retraction and camera movement, so the map stays on the anatomy.

Differentiate

Differentiates arteries from veins from the temporal phase of the signal — the order in which vessels fill and clear.

Design principles

Camera-agnostic. It works alongside the fluorescence systems already in the theatre — Stryker, Karl Storz, Olympus, Intuitive.

On device. Processing runs locally. There is no cloud dependency during surgery.

Workflow-neutral. No new steps in the sterile field, and nothing new for the surgeon to hold.

The surgeon decides. The system presents a reading. The clinical decision stays with the surgeon.

Clinical collaboration

We are looking for thoracic departments to develop this with.

Development happens in the theatre or it does not happen. Collaborations with leading Danish cardiothoracic centres are being formalised, and we have room for more.

What we offer
Early access. Hands on the prototype well before market. Co-development influence. The overlay, the workflow and the priorities are shaped by the departments using it. Publication opportunities. First-in-class work, with the clinical authorship where it belongs.
What we ask for
Operating-room access. Observation of relevant procedures, on your terms and your schedule. Clinical feedback. Honest reading of what the overlay gets right and what it gets wrong. Validation data. Anonymised fluorescence video, under an agreement drawn up with your department.

Two lines on your department and your case volume is enough to start.

Company

The same problem, followed for a decade.

Navisurg Vision continues a body of work on reading fluorescence signal quantitatively rather than by eye, carried from perfusion imaging into thoracic surgery.

Perfusion Tech Quantitative perfusion assessment from ICG video. The team behind it built the signal expertise this company rests on.
UltraGreen.ai The next step in the same line of work, and the origin of the patent families now licensed to Navisurg Vision.
Navisurg Vision Founded in Copenhagen to bring that reading into keyhole lung surgery.
