US Patent:

6597932, Jul 22, 2003

Filed:

Feb 20, 2001

Appl. No.:

09/785549

Inventors:

Wei Dong Tian - West Roxbury MA
Pierre Trepagnier - Medford MA

Assignee:

Argose, Inc. - Waltham MA

International Classification:

A61B 500

US Classification:

600317

Abstract:

An instrument for evaluating fluorescence of a heterogeneous tissue includes means for exciting a two-dimensional portion of the tissue surface with excitation radiation at a plurality of excitation wavelengths, means for collecting emission radiation from the two-dimensional portion of the tissue surface simultaneously with excitation of the portion, and means for forming a two-dimensional excitation-emission map of the excitation radiation and the simultaneously collected emission radiation and spatially averaging the excitation and emission radiation.
