Patent ID: 8649849

Claim:
An optical spectroscopy system to differentiate malignant tumors from benign tumors of one or more tissues comprising: at least one electromagnetic radiation source for illuminating one or more tissues; an intraoperative optical probe connected to the electromagnetic radiation source and adapted to contact the one or more tissues and adapted to transmit electromagnetic radiation from the electromagnetic radiation source to illuminate the one or more tissues and adapted to relay a light-scattering reflectance, a time-resolved auto-fluorescence and a diffuse near infrared emission; a detector connected to the intraoperative optical probe and adapted to capture and receive the light-scattering reflectance, time-resolved auto-fluorescence and diffuse near infrared emission from the one or more tissues; and a computer device connected with the detector, wherein the computer device comprises one or more tissue classification algorithms comprising minimal distance method and support vector machine algorithm that differentiate a malignant tumor from a benign tumor.
