Our approach

More information.
With just light.

We turn the way tissue interacts with polarized light into a view of its underlying structure.

01

Illuminate.

Polarized light interacts with tissue without touching it. No injected contrast agent is needed.

02

Reveal.

Mueller polarimetry maps the optical properties of tissue, revealing local fiber orientation.

03

Follow.

Choose a point, and our algorithms follow the local orientation field to trace the fibers, bringing fiber tracking closer to real time.

Applications

One approach.
Many surgical perspectives.

We are developing polarimetric imaging to explore tissue structure across a range of surgical applications.
