DoseOptics LLC

DoseOptics LLC is a Dartmouth spinoff based in Lebanon, New Hampshire that builds BeamSite, the first FDA-cleared camera system to record radiation therapy as it happens by imaging Cherenkov light - the faint glow emitted when a radiotherapy beam passes through tissue. The technology lets radiation oncology teams literally see the beam on the patient in real time, turning an invisible treatment into a video they can review, catching positioning errors and delivery anomalies that were previously undetectable.
