Method and apparatus for regulating light administered at a patient treatment site

摘要

In one embodiment, apparatus is provided with at least one solid-state light emitter, at least one fiber optic light guide, at least one photosensor, and a control system. Each of the at least one fiber optic light guide has a first end that is independently positionable with respect to the solid-state light emitter(s) to receive the light emitted by the solid-state light emitter(s). Each photosensor is positioned to receive light emitted from a second end of one of the light guides. The control system is operably associated with the solid-state light emitter(s) and the photosensor(s) to regulate the light output of the light emitter(s) in accordance with measurements received from the photosensor(s).
