Abstract
A method and system is used to locate tissue for removal during a resection. The system includes a container that holds a photoactivatable agent capable of binding with unwanted tissue at a treatment site, a light source, and a viewing device. The light source is adapted to continuously output light that causes fluorescence of the photoactivatable agent in unwanted tissue. The system provides fluorescence-enhanced viewing of the treatment site through the viewing device. The viewing device has a filter that filters out light from the light source that is reflected from the treatment site while allowing a fluorescence emission from the photoactivatable agent to pass therethrough to each eye of the user. The light from the light source and the fluorescence emission are in different regions of the energy spectrum.
