Abstract

A system SY for determining a tissue type TY of a tissue region TR is provided in which the distal ends OFDEof at least three optical fibers define a plurality of intersecting optical paths IOPwithin the tissue region TR. A tissue signal Qindicative of a tissue type TY for the respective optical path IOPis generated from said spectral measurement data SMD corresponding to each of the plurality of intersecting optical paths IOP. Each tissue signal Qis compared with a reference threshold QRT for the tissue type, and with an average of the tissue signals QMA. At least a portion of the tissue region is identified as the tissue type TY if i) every tissue signal Qin the tissue region TR indicates that its corresponding tissue is not the tissue type TY in the comparison with the reference threshold QRT and ii) at least one of the tissue signals Qin the tissue region TR lies between the average QMA of the tissue signals Qand the reference threshold QRT, and a difference Δ between the at least one tissue signal Qand the average QMA of the tissue signals Qexceeds a predetermined value ΔP.
