Reveal Surgical is developing a real-time intraoperative cancer detection (virtual biopsy) device based on Raman spectroscopy. The intraoperative probe system relies on the unique signature of light scattering that occurs when light is used to illuminate different types of tissue.

Why we invested

At the margins of tumors, it is not always possible to differentiate diseased from healthy tissue. Reveal’s technology allows surgeons to get clear information about the type of tissue they are studying during surgery.

This innovative, non-invasive approach to cancer detection will provide surgeons with sub-millimeter accuracy on tissue characterization to help them make decisions while seamlessly integrating into their workflow.
