Abstract

Lasers have become a generally accepted tool for surgery due to their advantages compared to traditional approaches like the scalpel. However, lasers lack a feedback system for safe laser guidance. This problem prevents the potential laser application for a lot of medical cases in the clinical environment. In this work, a new tissue differentiation modality which might be implemented as a feedback system using remote speckle-sensing is presented. This modality is tested on three tissue types and the results are discussed.
