Method and System for Distinguishing Between Stone and Tissue with a Laser
The present disclosure provides a method and system for distinguishing between a stone and a tissue based on reflected light from the stone or the tissue. It is to be appreciated that the efficiency of treatments using lasers often depend upon the relative position and orientation of the optical fiber tip with respect to the target.

For example, where a stone is the intended target, unintentionally activating the laser while aimed at tissue could damage the tissue. This may lead to unnecessary complications, and in some cases, it can also lead to permanent damage to the tissue, which could make portions of the body of the subject dysfunctional.
