Abstract
(EN)
The present invention relates to a system comprising: a surgical instrument comprising an incident light source and a sensor for using incident light from the light source to generate a signal indicative of fluorescence of a subject tissue into which a fluorescent medium has been introduced; and a processor configured to receive the signal and to determine a tissue characteristic of the subject tissue responsive to the response of the fluorescence as indicated by the signal.
