About Us
Our Mission
We develop groundbreaking imaging technology that enables real-time visualization of intracellular oxygen — for the first time. By bringing this capability to the clinic, we aim to transform how oxygen is used as a marker of disease, from improving tumor detection during surgery to enhancing treatment precision in radiotherapy and beyond.
Our Story
Our technology originated from pioneering research in the Optics in Medicine Lab at the Thayer School of Engineering at Dartmouth. What began as a scientific effort to image oxygen at the cellular level has evolved into a mission to bring that innovation to the clinic. Our team brings together expertise in optics, engineering, and oncology, focused on turning this breakthrough into tools that meet real clinical needs and improve patient outcomes.
Our Technology
Our platform uses a unique optical signal emitted by Protoporphyrin IX (PpIX), a molecule that can be induced throughout the body using the FDA-approved prodrug 5-ALA. This signal, known as delayed fluorescence, reveals tissue oxygen levels at the cellular scale. We’ve developed a system that captures this signal across an entire surgical field at video frame rates.
